Duo Pak

Multi-Circuit Condensing Unit

The Duo-Pak condensing unit will perform the functions of two condensing units. It will replace either a 99M (1 hp) or 69M (3/4 hp) medium temp condensing unit, and a 249L (2-1/2 hp) or 199L (2 hp) or 149L (1-1/2 hp) condensing unit. This combo unit will supply refrigeration to both a walk-in cooler and a freezer. Duo-Pak is available as PCL (pre‑charged with refrigerant and up to 40' of pre‑charged lines provided), PC (pre-charges with refrigerant for up to 50' line length) or PR (pre‑assembled remote system shipped with nitrogen holding charge).

Installer only has one unit to mount (reduces the amount of space required)
Single point electrical
Easy access electrical panel
Timer for freezer is pre-wired and mounted in electrical box
Compressors are branch circuited and individually fused
Crank case heaters (outdoor models) only come on when unit is in off-cycle (reduces excess heat that the compressor has to overcome during warm conditions and reduces energy consumption overall)
Shipping cost is reduced
Outdoor models come standard with headmaster valves (optional on individual units) Note: headmaster valves allow refrigerant to bypass the condenser coil during cold weather conditions by maintaining a minimum head pressure.
Color-coded wiring
