HVAC VFD/Inverter

    1. Air Cooled VFD Cabinet, AS700STEP's air cooled VFD was particularly developed for HVAC industry. It adopts mature control technology, the ratio between voltage/frequency is automatically adjusted according to the motor load, thus greatly improving the efficiency of the system.
    1. Liquid Cooled VFD Cabinet, AS720AS720 series liquid cooled VFD adopts STEP's mature platform of VFDs. The radiator of the general VFD is replaced with a cold plate cooled by refrigerant, which greatly reduces the size of the VFD while saving the cost. The power of cold plate VFD covers a range from110kW to 710kW.
