The nominal flow rate is between 0.8 m³/h and 46 m³/h (3.5 gpm to 203 gpm), depending on the model. The minichillers of the HYFRA eChilly/eChilly+ series use a water pressure of 2.2 bar to 3.3 bar (32 psi to 48 psi). The nominal volume flow for these units is 0.14 m³/h to 0.77 m³/h (0.6 gpm to 3.4 gpm).More Information
