Refrigeration dryer DRYBERG RFE77 , 4620 Nm3/h
High-performance heat exchanger for DRYBERG RFE
EXTENDED HEAT EXCHANGE
RFE dryers feature a very robust 2-in-1 aluminum heat exchanger with an air-to-air heat exchanger, the air-to-air heat exchanger with a water separator connected externally through Victaulic connections. This advanced heat exchanger has been specially designed to maximize the heat transfer coefficient. Oversized Demister separator ensures optimum dew point performance and guarantees industry-leading pressure drops.
Air-air heat exchanger
Hot and humid air enters the air-to-air heat exchanger, where it exchanges heat in the total counterflow with the existing cold air. Pre-cooling saves energy by reducing the heat load to the evaporator area. The cold, dry compressed air flows through the secondary side of the air-to-air heat exchanger, where it is reheated by the hot supply air that pre-cools it.
Air-to-cooled mass heat exchangers
The precooled air enters the heat exchanger from air to cool where it is cooled to the required dew point by exchanging heat in countercurrent with the cold mass thermal fluid, allowing for maximum heat exchange.
