The Enfinity™ horizontal water-source heat pump gives engineers the flexibility to design efficient, cost-effective geothermal or boiler/tower heating and cooling systems for schools, offices, healthcare facilities, and other buildings, says the company. Standard range (55 to 110 degrees F) and extended-range/geothermal (25 to 110 degrees) models in 0.5- to 5-ton capacities feature four small-footprint cabinet sizes. The units can be specified with left- or right-return and straight- or end-discharge configurations, or they can be modified on site using interchangeable airside panels. They have up to a 17.5 EER. Units sized from 19,000 to 60,000 BTUH use R-410A.
