Refrigeration systems

Measured are the pressure and temperature in the pipes of refrigeration units. But also the function of the ventilator motor or the expansion valve is monitored as well as the filter function and the temperature in the cold room. Particularly large refrigeration systems are very often operated with a (H)CFC- / HFC refrigerant. In this case, all components in contact with the medium must be made ofhigh-quality stainless steel (e.g. 1.4571, 1.4301), and also in the selection of the sealant material, the right choice, e.g. NBR (acrylonitrile butadiene rubber) or FPM (fluoropolymer rubber) is of major importance to ensure a reliable operation.

For the use in refrigeration systems, JAKO offers a wide range of specific device designs. Special refrigerant-specific scales, screw-in, weld-in and flange sleeves in accordance with EN 43 772 or dial pressure gauges for low and high pressure ranges with or without transmitters make up the wide JAKO product range that allows realising customized solutions.

JAKO is also accredited verification centre and the partner of refrigeration system manufacturers and operators when it comes to the compliance with legal requirements regarding the use of verified pressure gauges in refrigeration systems.
