- This uncased OMNI coil is designed for 1.5 to 2 ton HVAC systems, providing efficient heat transfer and reliable performance for residential applications. Built with a heavy gauge steel cabinet and an aluminum slab, it is optimized for upflow installations and uses environmentally friendly R454B refrigerant. The coil’s robust construction ensures long-term durability and consistent climate control.
- Omniguard® Total Corrosion Protection - Armstrong Air's enhanced evaporator coil helps protect against leaks and corrosion for long- term performance. A fully-insulated cabinet and pre-bent duct flanges with rolled edges allow for a tight fit to existing ductwork, preventing heating and cooling losses.
- Factory-installed TXV- Optimized to deliver the right amount of refrigerant providing high-efficiency and energy savings every day.
- Matched System- Armstrong Air's evaporator coils are specially designed and sized to match Armstrong Air heating and cooling products. Removable cabinets and a single drain pan offer quick access and easy clean up for lifelong performance efficiencies. Plus, when you add a matching coil, you get a system that runs at peak performance while maximizing efficiency.
- Fully insulated cabinet- Wall-to-wall insulation ensures less than 2% air leakage increasing efficiency and energy savings.
- ProtectionPro™ Refractory Detection System (RDS)- Factory installed RDS that protects your investment by taking action should refrigerant not remain sealed within the HVAC system.
- Anti-Microbial Protection- Drain pans are infused with an antibacterial agent that destabilizes the membrane of microorganism cells, disrupting the cellular function of odor-causing mold and bacteria so that they can no longer grow or reproduce.
- MHT™ Technology- Armstrong Air’s proprietary heat transfer system. The coil features rifled tubing to enhance refrigerant flow, while lanced coil fins increase surface contact between metal and air. They combine for maximum heat transfer and efficiency.
