Self Contained Refrigeration Units for Mortuary Coolers: The Complete 2026 Guide

Every upright mortuary cooler in the AMC line ships with a self contained refrigeration unit — a fully packaged, top-mount system that combines compressor, condenser, and evaporator in a single plug-and-play cabinet. No remote condenser, no field refrigerant charging, no hard-wiring on standard 115V models.

What "self contained" means

The Heatcraft PRO³ Top Mount Packaged Refrigeration System arrives factory-charged, factory-wired, and UL listed. It drops into the cooler ceiling, plugs into a dedicated grounded circuit, and runs on preset Dixell XR40CH controller defaults. Compare that to remote-split systems on large custom-built coolers, which require an outdoor condensing unit and licensed refrigeration piping.

2026 changes buyers should know

2026-forward PRO³ systems run next-generation low-GWP A2L refrigerants under new federal refrigerant regulations. That brings a highly efficient process with many new features — and new startup requirements around condensate drainage and hose adapters. Before energizing any 2026 unit, read the full documentation on our Packaged Refrigeration Manuals & Startup Guide hub, which hosts the latest manuals of operations from Heatcraft Corp.

Which coolers use these systems

The full upright line: 3 Body Standard Upright, 3 Body Extra Wide, 4 Body Extra Wide, 6 Body Dual-Door, plus roll-in and hybrid models. Each runs 34–40°F body holding on a dedicated 115V/20A circuit.

Buyer responsibilities

Self contained doesn't mean zero site prep. Depending on cabinet model, humidity, and run time, an external condensate drain or field-supplied condensate pump may be required — drainage and site readiness are the responsibility of the purchaser and installer. Review the manual before operation.
