Support with low-cost inverter panels (EBL series), shortening the investment recovery period for equipment.

By opening the valve and adjusting the inverter to the same flow rate as before, power consumption is reduced. For educational facilities, during breaks, the switch is operated to switch to low-speed operation for further energy savings. Since control using sensors for temperature, pressure, and flow rate is not performed, it can be implemented at a low cost. The low-cost inverter panel (EBL series) is used to shorten the investment recovery period. 【Features】 ○ Control method: The rotation speed of the pump motor is controlled by the inverter using a manual step switch. ○ Target equipment: Absorption chiller/heater Chilled and hot water pumps (11.0 kW × 2 units) For more details, please contact us or download the catalog.
