Nordyne 921955 Coil Assembly

The Nordyne 921955 Coil Assembly is a specialized 4 Ton Cased C Evaporator Coil engineered for high-performance heat exchange in residential and light commercial HVAC applications. This Tube & Fin Cased Coil is built with advanced Anteater coil technology, providing superior resistance against formicary corrosion—a critical factor for long-term reliability in varying environmental conditions. As a genuine Nortek replacement part, this aluminum evaporator coil is equipped with a 0.099-inch orifice and follows a one-stage operation design. It is fully compatible with both R-22 and R-410A refrigerants, making it a versatile drop-in solution for legacy system repairs or modern high-efficiency upgrades. The assembly features a durable white finish and is rated for a 10-amp minimum circuit, ensuring it meets the rigorous electrical and thermal demands of 4-ton cooling systems while optimizing overall high SEER performance.

Key Technical Benefits:

• Broad Compatibility: Supports dual refrigerant applications (R-22/R-410A) for maximum field flexibility.
• Corrosion Resistance: Anteater technology utilizes specific alloys to prevent premature leaks caused by household chemical vapors.
• Enhanced Heat Transfer: Optimized tube and fin geometry maximizes surface area for efficient thermal energy transfer.
• OEM Fitment: Designed specifically for Nortek/Nordyne air handlers and furnaces, ensuring proper static pressure and airflow.
• High-Efficiency Output: Engineered to help systems maintain high SEER ratings and reduce compressor strain.

Common Questions:

Is the Nordyne 921955 compatible with older R-22 systems?
Yes, this cased evaporator coil is engineered to function with both R-22 and R-410A refrigerants, provided the expansion device is correctly matched to the system requirements.

What is the primary benefit of the Anteater technology in this coil?
Anteater technology is a specialized metallurgical treatment applied to the aluminum components to combat formicary corrosion, which is a leading cause of pinhole leaks in modern evaporator coils.

Does this assembly include a factory-installed TXV?
The Nordyne 921955 typically ships with a 0.099-inch orifice; however, field installation of a Thermostatic Expansion Valve (TXV) may be required depending on the specific 4 Ton outdoor unit and SEER requirements.
