When conventional air-source heat pumps operate in colder ambient conditions, water vapor condenses on the cold source coil and freezes, restricting airflow & reducing efficiency. To remove frost, they rely on defrost cycles - interrupting heating, increasing energy use, & requiring backup heat sources. NexGen DOAS’s patent-pending FrostShield technology eliminates this inefficiency on their packaged heat pumps by preventing frost formation at the source. This means: ? No Defrost Cycle Disruptions – Heat pump operation remains continuous, eliminating defrost cycles where energy is consumed without providing heat. This ensures the building receives usable heat every minute of the hour without unnecessary energy waste. ? Smart Auxiliary Heat Integration – In extreme conditions, the system logic seamlessly switches to auxiliary heat while locking out compressors, reducing full-load amp draw by up to 50%. ? Lower MCA/MOCP Ratings – With compressor lockout, required electrical service capacity is cut in half compared to conventional heat pumps, reducing installation costs. ? Grid-Friendly Operation – By lowering peak demand, FrostShield minimizes strain on electrical infrastructure, supporting decarbonization and electrification efforts. ? Low Total Cost of Ownership – Reduced energy consumption, lower installed costs, and improved system longevity translate to long-term savings for owners. Custom Reps supports engineers designing efficient, grid-conscious HVAC solutions. With FrostShield, NexGen DOAS’s packaged heat pumps eliminate defrost inefficiencies, providing uninterrupted heating & lower energy use than conventional options.
