Heating and cooling power adapted to Quebec's harsh winters

Thermal capacities and technical specifications

The LENNOX MMLD central heat pump is a 4-ton outdoor unit (model MMLD048S6S) using R-32 refrigerant , which is more environmentally friendly than older gases. It offers a cooling capacity of 48,000 BTUs and a heating capacity of up to -25°C , making it an ideal choice for our harsh winters.

Among its most remarkable technical characteristics:

• Energy efficiency : up to 18.0 SEER , 9.5 HSPF , 12.0 EER

• Voltage : 220V single phase

• Sound level (outdoor): 62 dB(A)

• Dimensions : 37 in (L) x 15.13 in (D) x 55.88 in (H)

• Piping : 3/8 - 5/8 in

• Wi-Fi compatibility through integration with Samsung's SmartThings app

Reliable Samsung technology, suitable for all needs

The Lennox MMLD series, equipped with Samsung parts , incorporates major innovations such as the variable frequency compressor (inverter) , intelligent sensors , and a microprocessor control system for continuous adaptation to the actual thermal needs of the building.

The brushless motor (DC) compressor uses neodymium magnets to provide quiet operation and exceptional efficiency. This technology ensures better temperature control , while reducing energy consumption.

Versatility of indoor units

The MMLD048S6S outdoor unit can be combined with different types of indoor units depending on the layout of the premises:

• MFMD Floor Console

• 1-track M1WD or 4-track M22D/M33D cassette

• Ducted unit (high or medium pressure)

• MMD multi-position fan coil

This variety allows for great flexibility of installation, whether in a condo in Laval, a house in Longueuil or a commercial space on the South Shore.

An ecological, safe and standards-compliant choice

R-32 refrigerant is a low global warming potential (GWP) gas , and the system incorporates a leak detector inside, compliant with UL 60335-2-40 . In the event of a leak, the compressor is automatically stopped and the indoor fan is activated to ensure safe dispersal of the refrigerant.

Simplified maintenance and long-term reliability

Our certified refrigeration engineers handle the installation, after-sales service, and routine maintenance of these units. All components are easily accessible, and the robust construction (galvanized steel, anti-corrosion protection) guarantees a long service life, even in harsh environments.

Guarantees and subsidies

The heat pump is Energy Star® certified and eligible for certain provincial grants . It is covered by a standard 12-year warranty on the compressor and parts . An additional 10-10-10 warranty may be available.
