A design thought out for Quebec's climate

The Quebec climate requires systems capable of performing as well at -30°C as in the middle of summer at 30°C. The CANAIR 4C28 series was made for Quebec , and this is reflected in every detail:

• Heating capacity down to -30°C without loss of efficiency;

• Continuously modulated inverter compressor , ensuring stable comfort and reduced consumption;

• Corrosion-resistant TU1 copper coil for increased durability;

• Built-in exterior heating cables to prevent ice buildup;

• “Follow Me” function to maintain the exact temperature wherever the remote control is located;

• Cold air draft prevention function , ideal for starting in heating mode.

These features enable consistent performance, even in the worst winter storms, while ensuring superior comfort and quiet operation.

Cutting-edge technology for your comfort

Inverter technology: precision and economy

The secret of the CANAIR 4C28 lies in its inverter technology : it adjusts the compressor frequency in real time according to thermal demand. This means:

• Less energy waste , as the compressor never needs to stop and restart abruptly;

• Constant temperature , without the unpleasant variations of traditional systems;

• Extended system life due to reduced mechanical stress;

• Impressive silence : with only 65 dB(A) for the outdoor unit, sound comfort is guaranteed.

R-454B gas: efficiency at the service of the environment

R-454B is the new standard for low global warming potential (GWP) refrigerants. It is a great replacement for R-410A by offering:

• An environmental impact reduced by more than 75% ;

• Superior thermal performance;

• Better overall energy efficiency .

Exceptional energy performance

The CANAIR 4C28 - R454B 2-zone (outdoor model 4C28MC648H21 ) boasts impressive efficiency values :

These numbers aren't just data: they translate into real energy savings , a lower electricity bill , and a smaller carbon footprint .

Total flexibility for all configurations

The CANAIR 4C28 – R454B 2-Zone model can power up to six indoor units (depending on the chosen configuration). This allows you to adapt the comfort to each room:

• Living room and bedroom;

• Office and basement;

• Or any other combination depending on the size of your residence.

Thanks to its intelligent multi-zone , each indoor unit operates independently : you control the temperature room by room, optimizing comfort and energy consumption.

Thermal comfort is not limited to temperature; it also depends on the silence and gentleness of the air flow .

• In quiet mode , the CANAIR 4C28 emits less than 20 dB(A) indoors — barely a whisper.
