Three Frigomar 610NT 130,000 BTU units retrofit on a 132' Benetti. After testing the chillers, we were able to record a constant 20amp draw including pumps. On start up with a hot boat, the compressor will start at low speed (20 Hz) and approx 2amp with no peak current and then accelerates smoothly up to the max frequency (100 Hz) in order to cool or heat quickly. This is made possible with the BLDC compressors and inverter technology built into the system. With some vessels, power consumption is critical and the engineer thus have the option to restrict the units to eco mode where the hz will not increase above 45hz. This will restrict amp draw to approx 5.2 amps per unit. As water temperature approaches the set point value, the compressor slows down, keeping a constant temperature in silent operation and saving energy. In term of Seasonal Energy Efficiency Ratio, the average reduction in electrical energy consumption is 50%, compared to the equivalent traditional air conditioner. The new generation chillers are standard with a touch screen display and an optional switch board where all units can be controlled from one screen.
