Zephaire - 2-10 Ton (Horizontal) Water-Cooled Heat Pump Air-Conditioners

Our Zephaire water-cooled heat pump air conditioners are amazingly efficient, easy to use, and simple to install. We recommend coupling them with one of our evaporative fluid coolers or pond loop heat exchangers for ideal condensing temps and maximum equipment longevity with pristine closed-loop condensing water. However, they're also also frequently used with clean well or tap water in open-loop systems, or with other geothermal ground loop systems. These units are all built in the USA.
