The Frigomar CU50VFD is a self-contained, seawater-cooled marine chiller built around a variable-speed BLDC inverter compressor. The compressor modulates continuously between 20 and 100 Hz to match the cooling load, giving stable comfort and reduced electrical draw compared with a fixed-speed unit. A dedicated ECO mode delivers 18,000 BTU/h at greatly reduced power for light-load conditions. A detachable touch-screen display can be mounted up to 50 m from the unit.

Frequently Asked Questions
How many tons is the CU50VFD?
The CU50VFD delivers 50,000 BTU/h, which is approximately 4 refrigeration tons of cooling capacity.
Does it need a three-phase supply?
No. The CU50VFD runs on a single-phase 230 V / 50–60 Hz supply, which makes it suitable for vessels without three-phase power.
What is ECO mode?
ECO mode reduces the compressor output to about 18,000 BTU/h at roughly 0.85 kW input for efficient cooling when full capacity is not needed.
