The ChillGrille ceiling assembly brings upgraded airflow control to Coleman Mach non-ducted rooftop AC units. Omni-directional louvers let you aim conditioned air anywhere in the cabin, and the heat-ready design means this assembly works with both cooling-only and heat-pump-equipped Coleman Mach systems -- no separate heating grille required.
Standard ceiling assemblies on non-ducted RV air conditioners push air in fixed directions, leaving hot spots near the ends of your rig. The Coleman Mach ChillGrille solves that with omni-directional louvers that pivot to aim airflow toward any area of the interior. When you want wider, more passive distribution, close the louvers and the assembly automatically redirects conditioned air forward and aft through dedicated front and rear dampers -- giving you two distinct airflow modes from one unit.
Designed as a direct replacement for compatible Coleman Mach rooftop units, this assembly mounts to the existing interior ceiling cutout and connects to your AC unit's air plenum without modification. The heat-ready rating means the louvers and housing are built to handle warm air output from heat-pump systems, not just the cool output of a standard compressor cycle.
Pivot to direct conditioned air toward any area of the RV interior for precise comfort control.
Louvers open for targeted direction; louvers closed routes air fore and aft through dedicated dampers.
Rated to handle warm-air output from Coleman Mach heat-pump systems -- no swap-out needed for heating season.
Drop-in replacement for compatible Coleman Mach non-ducted ceiling cutouts. No ductwork required.
Non-ducted (also called "free delivery") RV air conditioning systems deliver conditioned air directly through the ceiling assembly into the living space, rather than routing air through a duct network. The ceiling assembly is the visible interior component -- it houses the return-air intake, the louvers or diffusers, and any dampers. Because all airflow passes through this single assembly, its design has a significant impact on how evenly the coach is cooled or heated.
The ChillGrille assembly replaces a worn, broken, or outdated ceiling grille on Coleman Mach non-ducted units. If your current grille has cracked louvers, broken dampers, or fixed airflow direction that leaves the front or rear of your rig uncomfortable, this is the upgrade.
Standard non-ducted ceiling assemblies are engineered for cooling only. A heat-ready assembly like the ChillGrille uses materials and damper construction rated for the higher air temperatures produced by a heat pump (typically 90-120 deg F discharge). If your Coleman Mach unit has a heat pump, always use a heat-ready ceiling assembly to prevent warping or damper failure over time.
This ceiling assembly is designed for Coleman Mach non-ducted rooftop AC units. It is not compatible with ducted systems or with non-Coleman Mach brands. Confirm your unit model number and ceiling cutout dimensions match before ordering. Not all Coleman Mach models use the same ceiling assembly -- cross-reference your existing part number or rooftop unit model to confirm fitment.
