York 4 Ton Horizontal Cased Coil for R-454B Refrigerant (21" High)

The York CT Cased Coils are specially designed for installation with our residential furnaces or modular air handlers as part of a matched air conditioning or heat pump system.

Our residential indoor coils can be applied with indoor thermostatic expansion valves (TXVs) according to the application. Most indoor coil models are available as flex coils for installation of the specific expansion device in the field. Select SKUs are available with factory mounted TXVs. Refer to the Technical Guide for the matched outdoor unit to determine the required indoor expansion device for your specific application.

CTF series full-cased coils are suitable for upflow or downflow applications. CTM series full-cased multi-position coils are designed for horizontal left, horizontal right, upflow, or downflow applications.

Standard Features:

• The rigid case construction provides structural support and eliminates screw heads protruding from the side of the cabinet that could damage property during installation.
• The cabinet is constructed of heavy gauge galvanized steel with a primer and finish coat that provides a high-quality corrosion resistant finish.
• MaxAlloy™ coil: These long-life aluminum coils are built to deliver lasting performance, efficiency, and reliability.
• Foil-faced insulation: The cabinet is insulated with a single piece of cleanable foil-faced insulation. The cabinet is designed so that all edges of the insulation are contained.
• Compact cabinet: With the coil and access doors removed, the cabinet has a 20.5 in. casing depth in all models, allowing ease of access in attics and applications where space is constrained.
• Thermoset drain pan: The drain pan is corrosion and UV resistant with a positive slope for proper drainage. The low water retention design maximizes indoor air quality and consumer comfort.
• Low leakage cabinet design: Fully gasketed doors minimize air leakage to no more than 2% when measured at 1.0 in. W.C. external static pressure, minimizing conditioned air leakage and infiltration.
• Duct flange: An integral duct flange is part of the coil casing for easy installation.
• TXV: Select factory-installed and field-installed models are available. They use Chatleff fittings, and no brazing is required.
