Description
Product Summary
The RDI Systems PC449LZOP-2E is a 4-1/2 HP low temp scroll air-cooled condensing unit from the RDI 120 Series PC Pre-Charged line rated at 17,323 BTU/h (-20°F SST, 90°F ambient, R-404A). It is wired for 208/230V 1-phase 60 Hz power.
RDI PC systems ship pre-charged with refrigerant for up to 50 ft of line, which shortens field charging time on walk-in cooler and freezer installations. The air-cooled cabinet is rated for indoor or outdoor installation.
Approved refrigerants: R-404A. Pair it with a matching evaporator sized to the box load; contact HVAC365 for a system match.
