The HYFRA Alpha series was developed as a stand-alone solution for recirculation cooling with water, oil and emulsions. It is mainly used in filtration technology. These recirculating chillers are equipped with high-power pumps featuring flow monitoring. At an adequate input pressure level, they keep the refrigerant in circulation. These chiller can be set up within a generous radius around the machine to be cooled.
70% refrigerant savings with microchannel
Thanks to sector-leading HYFRA microchannel technology, machines in the HYFRA Alpha series use up to 70 % less refrigerant. Power levels of up to 28 kW are possible on a footprint of only 0.5 m² – due to their compact design. This results in significant flexibility advantages when planning production area layouts and boosts productivity as well.
FleXX technology for demand-based operation
Depending on the performance class, easy-to-clean plate heat exchangers or solid shell & tube heat exchangers are installed in the HYFRA Alpha series. HYFRA Alpha recirculating cooler are also available with the innovative HYFRA FleXX technology that ensures energy-efficient, extremely precise operation with demand-based controls. The attached control cabinet is equipped with an ST120 controller that reliably monitors compression pressure and temperature.
Our HYFRA Alpha c series for cooling water, oil and emulsions offers reliable cooling power of up to 16 kW in a compact design. They are up to 40 % lower than the standard models in the HYFRA Alpha series. As an entry-level model, it also uses our energy-efficient HYFRA microchannel technology, thanks to which the refrigerant used can be reduced by up to 70 %. The frame and plate heat exchangers are made of durable stainless steel. Otherwise, the HYFRA Alpha c series is equipped only with essential components, making it the cost-optimized alternative. The new, continuously variable pressure transducer keeps the system from freezing. HYFRA Alpha c devices can be modified with a FreeSmart controller. Further equipment options can be added to these recirculating water chillers and are available upon request.
