 Heat Recovery Options For Even More Savings 🌱

In compressor, a high amount of heat is released during the compression of the air. A large amount of heat is recovered with a suitable oil/water exchanger placed at the oil tank outlet ofthe compressor. The hot water obtained with the heat recovery can be used in many areas in your facilities. By directing the hot air coming out of the compressor, a room can be heated when heating is required, or hot air can be given outside with thermostatic control, in accordance with seasonal changes. In this way, savings from the heating system and natural gas are provided.80% of the compressor’s total energy consumption can be recovered.

 Intake System

Air circulation inside the cabin with negative pressurized cabin andsealed cover structure.

Fresh air intake thanks to hot air evacuated at a point away from the suction.

Low noise level thanks to intake blinds.
