The split systems are mainly used for fan drives in which the power section is already integrated in the motor housing or the drive concept and the like provides a separate inverter or voltage regulator. Operating manual - translation into English © thermofin GmbH...
Page 9: Scope Of Application
Without an appropriately classified control cabinet, control units of the TCS series may only be operated in dry, weather-protected and properly air-conditioned rooms. Control cabinets from thermofin® company meet all of the important criteria for outdoor installation and therefore also enable trouble-free operation with a built-in TCS.

The hygienic circuit should prevent legionella formation and stagnation in the supply line of the thermofin® spray system. As soon as the adiabatic system is switched off, a counter begins to record the waiting time. When the set time is reached, the drain valve opens and the entire water line up to the main water valve is drained.
