    ECO GOLD Chiller The chiller mainly consists of a fully hermetically sealed compressor. The dissipation of the condensation and motor heat takes place via a fan-ventilated lamellar condenser. Here, atmospheric air is drawn in at the front of the device, heated up and discharged at the back and sides. To ensure proper air circulation the ventilation openings must not be covered up.
