2 CEILING-TEMP Features Ceiling-Temp unit coolers are designed for use in walk-in coolers and freezers with very low headroom clearance. Units mount flush to the ceiling to provide extra storage room. Ceiling-Temp unit coolers feature two-way air flow to provide for even circulation and temperature, hinged drain pan for easy serviceability, and are available in air and electric defrost models. SIZES There are a wide array of sizes available with capacities ranging from 5,00 to 27,00 BTUH at a 10 TD. Three through six fan models are available with air flow spanning a range of 1,200 to 3,270 CFM. HOUSING Rust free heavy gauge textured Aluminum is standard. Optionally available with white enamel coating. COIL The coil is constructed from seamless Copper tubes which are staggered and mechanically expanded into heavy gauge, corrugated, Aluminum fins, assuring maximum heat transfer. Optionally available with Copper or phenolic coated fins (phenolic fins are for air defrost only). FANS Fan motors and blades can be easily accessed by lowering the hinged drain pan. ELECTRICAL Available for 115V, 208/230V and 0V. All components are factory wired to terminal strips and are UL and cul listed. AIR DEFROST Air Defrost models (CTA) are designed for use in coolers down to 35 o F. ELECTRIC DEFROST Electric Defrost models (CTE) are designed for use in coolers and freezers down to -10 o F. MOTORS Standard models feature highly efficient Electronically Commutated (EC) motors PSC motors are also available for 115V/1 or 208/230V/1 requirements. All motors include thermal overload protection.
