The complete line of Envision commercial geothermal heat pumps feature two-speed compressors, reaching up to a 5.0 COP (coefficient of performance) in heating and a 30 EER (Energy Efficiency Ratio) in cooling in ground-loop applications. The systems use ultra-quiet scroll compressors mounted on double-isolation plates made of acoustically treated metal and wrapped in a compressor blanket to provide noise reduction. Two-speed compressor technology also improves IAQ by allowing extended run times. Features include an optional FX10 direct digital control platform, field-adjustable filter racks, status lights on the front of the unit for field service, and onboard diagnostics.
