Units are convertible to up-flow or horizontal design.

Key Features

  • Multi-Circuit, Copper Tube Coil
    Extra large surface area of Lennox designed coil provides maximum cooling efficiency, excellent heat transfer and low air resistance.  Coils on 090-240 models are face split with separate circuits, each circuit has its own expansion valve.

  • Expansion Valve
    For use with R-410A systems.
    Factory installed and piped.
    Multi-circuit coils are equipped with one thermal expansion valve per circuit.
    Valves are sized for best performance.

  • Refrigerant Piping and Drain Connections
    Refrigerant line inlets (knockouts) are provided on both sides of the cabinet.
    Refrigerant lines require sweat connections and are made internal to the cabinet.

  • Filters
    51 mm thick, throwaway fiberglass media filters are furnished as standard.  Filter rack design permits quick and easy removal of filters for servicing.

  • Belt Drive Blowers
    090-120-150 models are equipped with a single blower wheel.  180 and 240 models have dual blower wheels.  Centrifugal belt driven blowers deliver large air volumes quietly and with low power consumption.
