FENdefrost is Fenagy’s robust control system featuring adaptive algorithms that ensure reliable defrosting of industrial air-to-water heat pumps in cold weather.

Effective defrosting is crucial in freezing conditions to maintain efficiency and avoid downtime. Our intelligent system manages defrost cycles based on real-time conditions.
The built-in Winter Mode keeps evaporator fans running at low speed when the unit is idle, preventing snow accumulation and ensuring the heat pump stays ready for operation.
