The proven HYFRA Sigma series for cooling water recooling is equipped with high-efficiency plate heat exchangers. In combination with sector-leading HYFRA microchannel technology, the refrigerant used is reduced by up to 70 % in comparison to conventional devices. The low level of refrigerant used for devices with up to 30 kW of cooling power means annual leak tests are a thing of the past and also leads to a reduction in maintenance costs.
No leak tests up to 30 kW and up to 70 % less refrigerant thanks to microchannel technology
Energy costs are perceptibly lower when HYFRA Sigma recooling systems are used. Because the compressors always function at optimal efficiency, the plate heat exchangers are also extremely energy efficient. A 2-point pressure transducer that constantly regulates system pressure and has an early warning function for leak detection ensures smooth operation.
FleXX technology for demand-based operation
HYFRA Sigma models are also available with the innovative HYFRA FleXX technology that ensures energy-efficient, extremely precise operation with demand-based controls.
Our Sigma c series for cooling water offers reliable cooling capacity of up to 16 kW in a compact design. Designed to save space, they are up to 40 % lower than the standard models in the Sigma series. An entry-level recooling model, it also uses our energy-efficient HYFRA microchannel technology, which uses up to 70 % less refrigerant. The frame is made of durable stainless steel.
The attached control cabinet is equipped with an ST120 controller that reliably monitors compression pressure and temperature. Equipment options – for example, reinforced pumps and variable frequencies or voltages – are available upon request.
