Platzhalter-BildSince 1977 Beutler has been building gas warning devices for cooling and air-conditioning technology.

The first NH3 warning devices were developed in collaboration with the Swedish company Frigoscandia who fitted their cold stores with them. The facilities were continuously developed and adapted to the conditions in meat factories, cold stores and ships.

The aim was to develop devices that were low-maintenance and that would function as reliably as possible in adverse environmental conditions. Furthermore they should be simple for the company to operate, and maintenance through instructed operating personnel should be possible. This goal was achieved, demonstrated by 520 gas warning devices with 3 to 80 monitoring points and 4000 individual devices .

Our gas warning devices are installed in cold stores, meat factories, large bakeries, power stations, bank and office building air-conditioning systems, fishing trawlers, cruise and factory ships, dam research ships and patrol boats.

Several patents were granted for the sensor model.

Whereas initially only refrigeration plants with ammonia as a refrigerant were monitored, later other refrigeration plants in operation were also monitored as it turned out that the so-called halocarbon refrigerants such as R11, R12, R22 etc. have a harmful effect on the ozone layer. Meanwhile new refrigerants were developed to replace the above-mentioned refrigerants or old refrigerants such as ammonia were increasingly used.

Depending on the field of application, partially gas warning devices are made for the following refrigerants. R123, R134a, R170 (ethane), R290 (propane) R404A, R407A, R407C, R413A, R507, R600 (butane), R600a (isobutane), R717 (ammonia), R723 (ammonia 60% + dimethyl ether 40%), R744 (carbon dioxide) etc. The list cannot be exhaustive, as the development is not finished and it remains to be revealed which refrigerants will be the standard refrigerants in the future.

At any rate facilities which work with them must be monitored.

A further area is the monitoring of cooling and chilled water cycles for contamination with refrigerants. For this a gas sensor has been developed with can be built into a cooling and chilled water pipe.

For the monitoring of chilled water cycles for ammonia, our ion sensitive NH3 probe is available.
