BETTER AIR MEANS BETTER PERFORMANCE – Customer Application Case Study. Belimo

casestudy

We all know the situation; a meeting where your performance drops sharply. In most cases, this is a direct result of the poor quality of the air in the room.

Original Article from www.rotronic.com

Uncomfortable situations like this need not arise. CO2 displays by Rotronic make it easy to measure air quality, and the results can be used to initiate the appropriate measures. In an enclosed room, some 25 to 35 cubic metres of fresh air per person per hour are needed, given normal activities. This ensures that the carbon dioxide (CO2 ) content remains below 1,000ppm (ppm = parts per million [value of the proportion of carbon dioxide in the air]), and that the volatile substances exuded by humans are extracted to a sufficient degree. By comparison, the CO2 concentration in outdoor air is around 400ppm. The CO2 concentration is a good indication of the quality of the air in a room. The consumption of air rises particularly quickly in meetings, with many people in small rooms. By the time we notice this productivity has already declined. A CO2 sensor is the answer here. Alfred Freitag, Sales Manager for Switzerland at Belimo Automation AG, points out that a meeting should be interrupted when the CO2 concentration reaches 1,200 ppm and the room should be ventilated. The CO2 content in the air then drops rapidly, and productivity increases again.

The right to good air

Every person has a right to healthy indoor air (WHO). In the case of workplaces, the labour laws require that air quality and room climate must not represent a health hazard for employees. In the private sector, there are no regulations, and the owner is responsible. However, the Swiss Cantonal building regulations require energy-efficient buildings. This requirement can be met only when the buildings are airtight. Consequently, free exchange of air is no longer possible. Martin Bänninger, director of the SVLW (Swiss association for air and water hygiene), has this to say: “Most Cantonal building laws, or municipal building regulations, state the principle that a building must not endanger life or health of the building‘s users.” Furthermore, buildings must be erected according to the rules of the building trade, as laid down in the standards, directives and bulletins (SIA, SWKI).

Careful planning of ventilation systems

Today, however, an adequate supply of fresh air cannot be taken for granted. In densely built-up housing areas, normal ventilation through the windows is of limited value. A good room climate cannot be achieved by regular airing in all buildings – climate-regulating systems are a necessity. Building owners and ventilation planners should therefore conform to the specifications in the SWKI Directives – “Hygiene requirements for room air systems and devices” – starting with the positioning of the air intake, through the controls of the ventilation and heating systems to the instruction of the occupiers. In the case of more complex systems, the responsibilities for surveillance and maintenance must also be clearly defined. “The maintenance of the system should have high priority,” Alfred Freitag emphasises. To keep the ventilation systems functioning reliably, and to keep them hygienic, they must be carefully planned, constructed, regulated and maintained. Rotronic CO2 displays can then be used to monitor these ventilation systems, the data being read out via USB stick when necessary. Asked why Belimo decided in favour of the Rotronic CO2 displays, Alfred Freitag says, “We were very competently advised by Rotronic CEO Michael Taraba. He took care of our needs personally. In addition, the visualisation of the measured data was very important to us. They are simple and clear to read on the Rotronic display. Hitherto, Rotronic has proved a very reliable partner.” In addition, the Rotronic display permits global assessment of the air. It measures CO2 , humidity and temperature. This allows suitable countermeasures to be taken.

Introducing the Rotronic Monitoring System (RMS)

Rotronic, the largest Swiss manufacturer of products sold worldwide for the measurement of temperature and humidity, low dew point, CO2, differential pressure and airflow, has developed a complete new continuous monitoring system. The  Rotronic Monitoring System (RMS) checks, documents and visualises all required measurements in one place and makes them available to the user in the desired form. The data can be retrieved from anywhere, at any time by PC, Mac, tablet or smartphone. The system offers the highest level of performance, flexibility, versatility yet is easy to set up and operate.

The new Rotronic Monitoring system (RMS) provides one complete, flexible and yet simple environmental monitoring solution instead of many fragmented and complex systems working in isolation. The RMS software stores all recorded measurements securely in a system that the user can access at any time, data can be retrieved in any form and integrated into 3rd party systems, automated reports are easily generated and sent autonomously to key personnel. The heart of the system is server based web software with a secure SQL database. It records all data and events generating a range of alerts or warnings when customer defined criteria are breached. The RMS data loggers transmit the measured values to the software via wireless or LAN communication. The system has already been extensively tested successfully and proven its worth in large scale projects from global pharmaceuticals to local manufacturing companies. Customer feedback has enabled the system to continue to evolve, further enhancing many key features.

RMS

RMS is Highly Versatile

The modular system is suitable for use in laboratories, cleanrooms as well as production and manufacturing processes, stability cabinets and storage facilities throughout the food, pharmaceutical, biotechnology and cosmetic industries. It is highly suitable for monitoring data reliably for building management systems, across industry, museums and art galleries, archive stores and during the transportation of valuable products that are sensitive to variations in humidity and temperature levels. Data loggers record all data continuously with temperature, humidity and many other parameters. Third-party devices and existing systems can be integrated easily, making the RMS extremely flexible and allowing trouble-free expansion at any time. The system sends error messages and alerts by voice call, e-mail or SMS text messages as well as smartphone apps and switch outputs.

RMS has a Wide Reach and Data is Secure

Whether the user is abroad travelling, or working in an adjacent room access to the real-time data is guaranteed at all times. Control and monitoring is possible at any time via PC, Mac, tablet or smartphone. This gives peace of mind and also saves costs. Thanks to the SQL server database and the latest ASP.NET server software, high availability of the data is guaranteed and data security ensured by https protocols – regardless of the location or terminal device. It is also possible to encrypt all data.

RMS Meets All Regulatory Requirements

The new Rotronic Monitoring System meets all the regulatory requirements of GxP, FDA Annex 11, 21 CFR 11 and GAMP5. Thanks to the technical experts in the research and development department at Rotronic, installation is simple and uncomplicated. Local support is available through a worldwide network of Rotronic subsidiary companies and distributors.

The Hygroclip2 Advanced Revolution + Evolution + Innovation

This month Rotronic launch the Hygroclip2 Advanced range (HC2A). This is important especially for all our existing customers as the HC2A range will replace the existing Hygroclip2 (HC2) range.

HC2A-

Firstly, why change?

The HygroClip digital probe was launched in 1999 a revolutionary product that set the standard for accuracy, stability and changed the market by offering digital interchangeability and the inclusion of calibration and adjustment data on the probe. Ten years later our entire range was updated to the HygroClip2 a modern digital probe with a far greater digital capability. The HC2 provided more advanced calibration and adjustment as well as data logging and sensor diagnostics. Manufacturing processes were also improved. Since then it has nearly been 10 years again and so it’s time to further develop the HygroClip.

This year we have seen the launch of several new HygroClip solutions, Our Low Dew Point range (HC2-LDP) utilises our next generation AirChip4000, our new ATEX range (HC2-EX) gives a well needed update to our intrinsically safe devices and now the HC2A brings a number of subtle evolution’s to our flagship product the HC2-S.

HC2A.png
Nearly 20 years of development brings us to the HC2A

What’s new in the HC2A;

  • Much more robust HT-1 sensor which measures up to 93°C dew point
    • This sensor has been used in industrial probes for the past 12 months with proven performance
    • Allows measurements up to 95%rh at 95 °C
    • Also can withstand temperatures up to 200°C for longer durations
      • 190°C long term
      • 100 hrs at 200°C without increased drift
  • New improved housing with fully potted electronics
    • Further increasing the resilience of the HygroClip in the most demanding applications
  • Standardised and fully interchangeable filter for all  upcoming HC2A probes
    • Simplified filter design and options, also ensures sensors are mechanically protected even when changing Polyethylene and Teflon (PTFE) filters.
    • Industrial wire mesh and sintered steel filters are now single modules preventing leaks
  • Completely backward compatible to HC2
    • No new hardware or OEM device changes required!
  • Improved power management
    • Improved power supply regulation

So what does this mean to customers already using our HC2 probes.

Firstly what produces are affected. The changes to date impact our standard HC2-S(3) and HC2-SM probes as well as their Hydrogen Peroxide resistant counterparts the HC2-S(3)-HH and HC2-SM(3)-HH. Wider industrial ranges will be updated in due course.

Compatibility

  • HC2A and HC2 range devices use the same electronics so are completely compatible in terms of
    • Power supply
    • Power consumption
    • Digital and analogue outputs.

Changes

  • Filters;
    • Only affects HC2-S and HC2-S3 probes
    • The HC2A range incorporates a similar filter and filter carrier system as used on existing industrial probes.
    • The filter thread is different as such a new range of filters and carriers are available for the HC2A range
    • All HC2A probes (standard and industrial) will use the same range of filters and carriers
    • Wire mesh and sinter-steel filters are physically mounted to the carrier to prevent minor gaps and leakage.

filters.png

  • Dimensions
    • The HC2A-S poly-carbonate probes are 23mm longer
    • The HC2A-SM stainless steel probes are 2mm shorter

hc2a-dims.png

  • Construction
    • Automated sensor production
    • Greater space between sensor pins with domed construction to prevent condensation formation around connections
  • Sensing element
    • The HC2A range utilises our HT1 sensor. A subtle change to the IN1 sensor previously used. The new sensor design improves its physical properties and can measure up to 93°C dew point.

hc2s-accuracy

Price

  • Probe pricing remains the same as existing HC2 ranges.
  • Filters and carriers are also priced the same as current equivalents.

In Summary

Experience from over the past 50 years has been combined along with specific development and testing during the last three years to bring the further advancements to our flagship probe range. This gives us the confidence that the HC2A probes are already a mature humidity and temperature solution which further advances our customers ability to measure humidity with the excellent quality and long term stability expected of Rotronic products.

Measuring in clean rooms – Hands on with the Rotronic CRP5

For many years Rotronic products have been widely used in the monitoring and control of clean rooms, however more often than not our products are found out of sight quietly performing their measurement tasks away from areas with strict requirements for cleanliness demanded by modern clean rooms.

In the past few months Rotronic have launched two new clean room panels that are as the name suggests designed specifically for use within clean room environments.

Our flagship product in the field is the CRP5 which we will take a look at first.

CRP5 – Clean room From Rotronic

The CRP5 is a comprehensive clean room panel designed specifically for the requirements of modern clean rooms. Once installed the unit provides virtually no areas for dust to collect and the industrial glass front is extremely resistant to chemicals. With a fully configurable colour screen it is a stylish looking device!

CRP1a
Unpacking the CRP5, the glass front, colour display and stainless steel fittings make the CRP5 elegant, easy to clean and functional

Internally the CRP5 delivers some serious capability, providing potentially a solution for all your clean room measurement and monitoring requirements. Including;

  • Differential Pressure via internal diaphragm sensor (measurement via rear ports and front ports for flexible instalation and calibration).
  • Interchangeable humidity and temperature sensor.
  • Two fully configurable analogue inputs (for particle counters, lux meters etc)
  • Two configurable switch inputs (for pressure or door switches etc)
  • 6 configurable relays (for alarm triggers)
  • Digital connectivity via RS485 and Ethernet (Modbus or direct connection to Rotronic HW4 software)

A unique feature of the CRP5 is the optional flush mount humidity probe. The probe is locked into place through the use of magnets and can easily be removed for cleaning or calibration. An optional rear mount connection is available for Rotronic HC2 humidity and temperature probes should you wish to monitor ducts or spaces remote to the CRP5 itself.

CRP2
The unique removable Humidity and Temperature probe for ease of cleaning and calibration

The configurable colour display shows alarm conditions which can be acknowledged via the front panel. Alarms can be used to trigger relays associated with audible and larger visitual alarms. Interaction with the CRP5 is via four optical buttons –  their use is completely unaffected if operators are wearing protective gloves or not (unlike capacitive interfaces).

CRP3
Optical buttons can be used easily even when wearing gloves!

As an FDA and Gamp5 compliant device the CRP5 is a safe choice for regulated industries. The instrument can be used with 3rd party systems via its analogue outputs or industry standard Modbus TCP / RTU communication. Alternatively the CRP5 can be connected to the Rotronic HW4 software package to provide a one stop solution for monitoring, control and alarming. Pharmaceutical validation services as well as ISO 17025 (UKAS) calibrations are available from Rotronic if required.

To get some more detailed information about our clean room solutions give us a call or visit our website… Rotronic Website and CRP5 Datasheet

Next time we will look at the Rotronic CRP1 a dedicated temperature and humidity clean room panel for  applications with slightly simpler requirements but still demanding a clean installation  and high accuracy measurements!

Why do we need Warehouse Mapping?

Rotronic is proud to be able to offer an increasing range of products and services to meet the demands of our customers. The requirements for mapping especially thermal mapping are increasing dramatically in food, pharma and cosmetics production and transport industries.

But what is Thermal Mapping?
Mapping is the process of determining the temperature and often humidity gradients within a defined space. It is a vital process when the product is regulated by government agencies such as the US Food & Drug Administration (FDA) or the European Medicines Agency (EMA). Regulated materials must not exceed strict storage conditions. Fixed limits will typically exist for humidity and temperature both in terms of the absolute value and also the allowable rates of change. Mapping serves as a baseline for proving compliance within the storage spaces.

The reason for increasing regulatory compliance is to ensure products do not spoil or otherwise degrade during production, storage and transport. Warehouses are notorious for having warm or cold spots that are outside of the regular control specification. A proper mapping study serves to locate these spots and either modify or avoid the problem area. Similar problems can occur during transportation so increasingly transport is at least monitored if not fully controlled and mapped.

At 4.3 million square feet, the largest warehouse in the world is the Boeing Everett factory in Everett, WA USA. It was originally designed to construct the Boeing 747.

An FDA Form 483 is issued to a company’s management at the conclusion of an inspection when an investigator(s) has observed any conditions that in their judgement may constitute violations of the Food Drug and Cosmetic (FD&C) Act and related Acts.

Mapping in General
A mapping strategy is needed for several reasons. It is important for regulators or quality managers to understand the philosophy employed for the mapping. A documented strategy will decrease questions from any regulators reviewing your mapping study. The strategy document also helps them understand the data that is produced by the mapping process. The document acts as a tool for collaboration as other people may suggest ideas that will make your study produce better data or make your effort more efficient.

As the mapping study progresses from start to finish, the strategy document acts as your reference guide, ensuring you remain true to the agreed upon process and do not make changes that will negatively affect the study. A typical strategy is usually comprised of a few written paragraphs that includes a description of the warehouse space, the type of equipment used, the number of sensors to be used, a general idea of the sensor placement, and the duration of the study. It is not unusual for the mapping strategy to change as it evolves. Writing a detailed document at the early stages of the project may cause re-writes that can increase the total length of the project. It is usually more efficient to fully document the warehouse mapping project after the strategy is agreed. Think of the strategy document as a proposal for your mapping team or the approval team so they can buy into and understand your mapping strategy. It may also facilitate the final approval stage, later in the project, because the auditor already understands the warehouse mapping project.

Continuous Monitoring After the Warehouse Mapping
Continuous monitoring is a best practice within controlled and regulated spaces. The mapping study will determine the hot and cold zones for “worst case” sensor placement. These worst case locations should be considered when installing a permanent, continuous monitoring system. The number of sensors used for a permanent system will be far fewer than what is required for the mapping study. In some cases, continuous monitoring may require only a few sensors once the problem areas have been determined through the mapping study. A continuous monitoring system offers peace of mind as product components, manufacturing space, or storage space are maintained and on record as meeting specified environmental conditions.
