The Frigomar CU70VFD shares the CU-series variable-speed BLDC inverter platform in a larger 70,000 BTU/h (≈6 ton) capacity. It runs on a single-phase 230 V supply and offers an ECO mode of 24,000 BTU/h for efficient part-load operation, making it well suited to larger yachts and light commercial installations that still require single-phase power.
Key features
- 70,000 BTU/h (~6 tons) from a single-phase 230 V supply
- Variable-speed BLDC inverter compressor, 20–100 Hz modulation
- ECO mode: 24,000 BTU/h at ~1.2 kW input
- Detachable touch display, up to 50 m remote cable
- R410A refrigerant, seawater-cooled condenser
