Innovative temperature and ventilation control with Trevira CS Bioactive from Airtex GmbH

(lifePR) (Hattersheim, ) Be it hot or cold, cool or warm, damp or airless: the way we feel the atmosphere is of fundamental importance for our efficiency, and this is especially so at work. Series of scientific tests have shown that people undertaking light activity at room temperatures of around 20°C find air speeds over 0.2 metres per second to be uncomfortable. Climatic conditions assume a no less important role, in the food industry for instance, where foodstuffs can spoil if the same temperature is not maintained at each stage in the production, storage and sales areas.

Conventional HVAC (heating, ventilation & air conditioning) systems mostly operate with ventilation ductwork made from metal. Being good conductors of heat, however, metal ducts are liable to fall below the dew point and are susceptible to humidity. Cleaning them is no easy matter, since they are difficult to access. Consequently contaminated air and bacteria may become the source of impurities that are hazardous to health. In addition, unpleasant draughts may affect the workforce, since metal ducting blows cold air into spaces, like large wind machines.

In contrast, air cooling using textile ventilation systems is based on the displacement principle. With textile ductwork the total surface functions as an air outlet. Air enters at a low speed, inflating the textile sock. The resulting pressure dispels air through the fabric uniformly and releases it gently into the surroundings.

With its textile ventilation systems, Airtex GmbH, a specialist in HVAC products, offers customised solutions for every workplace and area where particularly high requirements exist in terms of clean air and the systems make for a pleasant environment.

The selection of the right material is critical when it comes to the functional properties, lifespan and appearance of textile ventilation ductwork.

The latest generation of such ducts from Airtex is made of Trevira CS Bioactive material. As a supplier of textile ventilations systems, Airtex uses the combination of flame retardant and antimicrobial properties of Trevira fibres in the HVAC field. The Airtex Bioactive fabric is, in addition, antistatic and non-absorbent. Resistance to abrasion is very good, both in wet and dry conditions. At the same time it works as a highly effective filter. The special textile surface retains particles of dirt, mould and bacteria. In all this Airtex Bioactive remains permanently durable and the anti-microbial and flame retardant properties are unaffected, even after frequent washing. Airtex textile channels achieve a lifespan of 10 to12 years.

Thanks to its built-in safety concept, Airtex Bioactive is ideally suited for use in areas where high requirements in terms of hygiene apply, such as the food or electronics industries, in laboratories and hospitals, production halls, refrigerated warehouses and supermarkets. Textile ducts are also found in refrigerated transport, in office blocks, hotels, discothèques, theatres and residential buildings.

Textiles in Trevira CS Bioactive satisfy in like manner the requirements in terms of preventative fire safety and enhanced hygiene. With this fibre the flame retardant property is supplemented by an added antimicrobial function, in that a silver-based agent is firmly embedded in the fibre polymer. The additive exercises a permanently antimicrobial effect and is not affected either by frequent washing or usage. In its action this effect emerges on the surface, without the agent migrating into the environment.

What advantages do textile air ducts offer over metal ducts?

- Even large amounts of air (in excess of 50,000 cubic metres per hour) are circulated and they are totally draught-free and uniformly distributed in work areas.
- Air speeds of less than 0.2 metres per second create a comfortable atmosphere for workpeople.
- Textile air ducts make it possible to work with substantially greater differences in temperature. In the same time they are capable of transmitting considerably more cold or heat than conventional ventilation systems.
- Desired room temperatures are attained faster than with traditional systems: shorter running times of ventilators make for energy savings.
- Airtex Trevira CS Bioactive textile ductwork functions noiselessly and due to their sound-absorbent properties acts as a sound muffler in addition.
- Textile air ducts are easy to maintain, can be assembled and dismantled quickly and are machine-washable at 30°C.
- Due to their low weight and volume it is possible to cut transport and storage costs to a minimum.
- Colour and shape combinations enhance appearance.

Based in Kerken, Germany, Airtex GmbH has been working successfully in the refrigeration, air conditioning and comfort sectors since 1984. Among its main customers it now numbers large concerns from the international food industry, together with small and medium-sized companies. All Airtex materials are tested to DIN 24 185 and carry the TÜV seal of approval. (German Association for Technical Inspection).

In 1991 company head Hans de Zeeuw gained the innovation award of the International Techtextil Symposium for his groundbreaking work on air circulation, using technical textiles.

With the introduction of the Airtex System Bioactive in 2006 the company set a further milestone in HVAC products, underlining the importance of Trevira special fibres for modern technical textiles. (
