Compulsory for motors with an output of 15 kW and above. - Differential pressostat for the detection of clogged filters. - Differential pressostat for control of air flow. - Smoke detecting station in accordance with the NF S 61-961 standard. - Refrigerant leak detector (with CIATrtc control). This allows prompt identification of gas leaks, guaranteeing the safety of any people in the vicinity. Installation of the device ensures compliance with European standards F-GAS and EN378 as well as ASHRAE 15.
