It is possible to convert pumps to inverters at a low cost.

By opening the valve and adjusting the inverter to the same flow rate as before, power consumption is reduced. Since control is not performed using sensors for temperature, pressure, or flow rate, it can be implemented at a low cost. Five inverters are compactly installed on one panel. 【Features】 ○ Control Method: Fixed frequency (constant flow) control ○ Target Equipment: Absorption chiller/heater Primary chilled and hot water pump (2.2kW × 2 units), Secondary chilled and hot water pump (3.7kW × 3 units) For more details, please contact us or download the catalog.
