Case of Installing a Tank Receiver While there is no easy way to calculate how much you can save by purchasing a larger receiver, the logic is simple. A receiver tank's key advantage is its zero energy consumption and low maintenance. Switching Load to Idle Kaeser or another fixed-speed compressor will use its maximum motor horsepower and kilowatt draw when it is fully loaded. Once the machine reaches your set pressure, it will receive a signal to turn from load to idle. The machine's power consumption drops by 60% when it is in idle. Let's show you how it works by using a Kaeser 75 horsepower CSD compressor. 75 horsepower is equivalent to 55 kW 55 kW is the consumption of a Kaeser compressor 75 HP at full load. It uses 22 kW in idle. If the plant is operated for 8,000 hours per annum, its power consumption will be $57,200 (55kWx 8,000 hours x $0.13) There are 20600 hours of loaded time without the use of a receiver tank. The total number of hours that can be run without a ...
