A device sized for large volumes

With a cooling capacity of 33,000 BTUs and an efficient heating capacity down to -30°C , this Midea wall-mounted heat pump is designed for the harsh climates of Quebec. We regularly recommend it for open-plan spaces, residential lofts, or even professional premises requiring significant thermal coverage without complex centralized installation.

Its high-performance motor, combined with variable frequency inverter technology, guarantees stable temperature maintenance, while reducing peak power consumption.

A new generation refrigerant: R-454B

One of the major advantages of this unit is its use of R-454B refrigerant , a gas with low environmental impact (lower GWP than R-410A) and already in compliance with future regulations. It is a responsible choice that responds to the ecological transition of the HVAC sector, while ensuring high-level thermal performance.

At AirGreen, we have trained our technicians in the specific features of A2L refrigerants such as R-454B, particularly in terms of safe installation, leak detection and maintenance.

Compact dimensions for simplified installation

Despite its power, this unit remains compact:

• Indoor unit: 46.88 x 11.25 x 14.63 inches

• Outdoor unit: 37.25 x 16.13 x 31.88 inches

It integrates easily into most residential or commercial configurations, without requiring major modifications to the existing infrastructure.

Professional installation with AirGreen
