Pressure compensation valves are used to offset the variations of slow pressures and of low amplitude (air pressure variations, hygrometry or temperature variations). They are not designed to absorb sudden or exceptional variations. Important variations can take place : • when the enclosure is rst put into service or when the cold is The best location for restarted After prolonged opening of doors valves is where pressure • on defrosting variation are the Most • at cold restart after defrosting Variations such as those create a shock wave likely to bring regular. It is advisable to about damage even so far as to cause the collapse of walls move them away from or ceiling. fans and angles. Those phenomena are induced by the running and/or design of refrigerating facilities. It is incumbent on the customer to take appropriate measures to reduce those risks. The conditions for the commissioning of cold rooms equipped with valves must comply with instructions set out in DTU 45.1 NFP 75-401-1. TS 20 valves for small cell : • average debit : 8 m3/h, • power : 8 W under 230 V, • mounting only on vertical panel of maximum thickness 130 mm TS 22 and TS 22+ valves airtight, in waterproof lids : • average debit : 15 m3/h, • power : 16 W under 230 V, • TS 22 is mounted on vertical and ceiling panel of thickness 60 to 120 mm • TS 22+ is mounted on vertical panel of thickness 150 mm • Threshold of release 20 Pa TS 25 watertight valves with heating cane anti-icing : • average debit : 30 m3/h, • heating strip power : 40 W under 230 V, • mounting only on vertical panel of maximum thickness 220 mm • Threshold of release 100 Pa This valve can be transformed into type TS 25 P by a simple modication (transfer of spring blades) to mount it in the ceiling. most economic solution
