Velair 22571WU 21K BTU VSD Smart 115V Marine Air Conditioner

The Velair 22571WU is a self-contained 21,000 BTU Variable Speed Drive (VSD) marine air conditioner designed for superior efficiency and climate control on boats and marine vessels. This advanced unit operates on 115V power and features reverse-cycle heat capability for year-round comfort.

Advanced VSD Technology:

• Brushless DC motor compressor with inverter technology continuously adjusts speed based on cabin temperature
• Variable Speed Drive operates between 20-100 Hz for optimal efficiency
• Twin rotary compressor delivers up to 21,000 BTU/h maximum cooling output
• Soft start capability reduces electrical system strain during startup
• Electronic expansion valve for precise refrigerant control

Intelligent Climate Control:

• Smart temperature management runs at maximum power for rapid cabin cooling
• Automatically reduces power consumption once set temperature is reached
• Maintains optimal comfort with minimum energy usage
• Reverse-cycle heating for cold weather operation

Marine-Grade Construction:

• Self-contained design simplifies installation in marine environments
• Reverse blade brushless fan motor for quiet, efficient airflow
• Meets EMC 2004/108/EC electromagnetic compatibility directives
• Built specifically for marine applications and harsh saltwater conditions

Unlike traditional fixed-speed marine air conditioners, the VSD technology in the Velair 22571WU continuously modulates compressor speed to match cooling demand, resulting in significant energy savings and more stable cabin temperatures. The brushless DC motors provide longer service life and quieter operation compared to conventional AC motors.
