The LPF for HFC / HFO refrigerants has a maximum pressure of 42 bar, while the LPF-D for CO2 has a maximum pressure of 60 bar.
LPF is specially designed for refrigeration applications with many key features such as a shut-off function; the LPF closes as tightly as a solenoid valve (<1ml/min).
The ‘equal percentage flow curve’ allows the LPF to open fast in the case of high load demand and to perform control more accurately under low load conditions.
The LPF is equipped with a new coil with protection IP67 class and the cable length has been extended from 1.5 meters up to nine meters to meet remote installation needs.
The LPF electronic expansion valve can replace a thermostatic expansion valve with a cooling capacity of up to 30kW and is compatible with Sanhua's controller SEC series.
