Commercial Heat Pump Condensing Unit – Reverse Cycle

Designed for applications with remotely located indoor air handler units or gas furnaces (dual-fuel) with indoor add-on coils.
Units are shipped completely factory assembled, piped and wired.

 

Key Features

  • R-410A Refrigerant
    Non-chlorine, ozone friendly, R-410A.
    Unit pre-charged with refrigerant.

  • Outdoor Coil Fan
    Direct drive fan moves large air volumes uniformly through entire condenser coil for high refrigerant cooling and heating capacity. Vertical air discharge minimizes operating sounds and eliminates damage to lawn and shrubs.

  • Copper Tube/Enhanced Fin Coil
    Lennox designed and fabricated coil.
    Ripple-edged aluminium fins.
    Copper tube construction.

  • Reversing Valve
    4-way interchange reversing valve effects a rapid change in direction of refrigerant flow resulting in quick changeover from cooling to heating and vice versa.

  • High Pressure Switch
    Shuts off unit if abnormal operating conditions cause discharge pressure to rise above setting.
    Protects the compressor from excessive condensing pressure.

  • Scroll Compressor
    Compressor features high efficiency with uniform suction flow, constant discharge flow and high volumetric efficiency and quiet operation.

  • Defrost Control
    Solid-state time/temperature defrost control is furnished as standard equipment.

  • Cabinet
    Heavy gauge steel cabinet with five station metal wash process. Powder paint finish provides superior rust and corrosion protection. Heavy duty steel base channels raise the unit off of mounting surface away from damaging moisture. Unit lifting holes and forklift slots furnished in base rails.

  • Refrigerant Line Connections, Electrical Inlets, Service Valves
    Sweat connection vapour and liquid lines are located on corner of unit cabinet.
    Fully serviceable brass service valves prevent corrosion and provide access to refrigerant system. Vapour valve can be fully shut off, while liquid valve may be front seated to manage refrigerant charge while servicing system.
    Refrigerant line connections and field wiring inlets are located in one central area of cabinet for easy access.
