Product Features & Fitment

Optimized specifically for R-32 refrigerant, the CAPTA4230C3 utilizes engineered circuits and manifolds alongside an AlumaFin7 all-aluminum design to prevent formicary corrosion. The factory-installed thermal expansion valve (TXV) ensures precise refrigerant control across both air conditioning and heat pump setups, while an integrated R-32 sensor provides continuous, long-term monitoring over the entire lifespan of the coil.

Encased in a durable galvanized steel cabinet with a leather grain-embossed finish, the unit features foil-faced insulation to limit cabinet sweating. Installation and service are simplified thanks to a shallow cabinet depth for easier attic access, a single front access panel, standardized copper suction tube stub lengths, and specialized drain pan rails designed to allow smooth coil removal and repositioning without compromising structural integrity.
