Water chiller 24000-70000 BTU/h 230V

VARIABLE-SPEED INVERTER TECHNOLOGY

The CU70VFD model is equipped with a variable-speed BLDC compressor. Rather than stopping and restarting regularly, it adjusts its speed to maintain the desired temperature inside the boat.

Its operating range extends from 20 to 100 Hz. When heating or cooling demands increase, the compressor speeds up. It then gradually slows down as the set temperature is approached.

• Up to 50% energy savings on average compared to a traditional on/off system.
• Start-up current limited to 2 A thanks to soft start, with no significant power spikes.
• More consistent temperature thanks to continuous power adjustment.
• Reduced noise and vibration associated with compressor operation.

This control system also reduces mechanical stress caused by repeated starts. A significant advantage for marine air conditioning systems that operate for long periods of time.

ECO MODE: 1,200 W OF ELECTRICAL POWER

When cooling demands are lower, the CU70VFD’s ECO mode limits the compressor’s maximum speed to reduce power consumption.

In this mode, the cooling capacity is factory-set to 24,000 BTU/h, with a power consumption of 1,200 W. The unit then operates at reduced power, without utilizing its full cooling capacity.

• Maximum heating and cooling capacity: 70,000 BTU/h.
• Maximum power consumption: 3,800 W.
• Cooling capacity in ECO mode: 24,000 BTU/h.
• Power consumption in ECO mode: 1,200 W.

ECO mode is selected via the control system. It is particularly useful when cooling demand is moderate or when the available electrical power on board is limited.
