HW Chassis Series


The Adirondack-Aire HW Series zerOzone chassis is a direct replacement for American Air Filter/ Enercon HW series ducted horizontal water source heat pump units. The HW is a complete unit that contains the compressor, blower, air side heat exchanger, water side heat exchanger, safety components, and control components. Low voltage wiring is compatible with the original wall thermostat. Duct connections are identical and line right up with the existing ductwork. A full range of unit sizes are available and each are dimensionally identical to the original for a fast, easy, and trouble-free installation.

Proven technology, quality components, careful design and testing and the latest in reliability and efficiency advances mean long unit life, user satisfaction, and lower energy costs. Consider the extensive list of standard features which includes: powder painted drain pan, refrigerant circuit access ports, high efficiency PSC blower motor and dynamically balanced DWDI blower wheel, evaporator freeze protection, water coil freezestat, high-pressure over protection, and lockout circuit. Adirondack-Aire is the replacement solution for upgrading old, worn out, inefficient original chassis. Heavy gauge mounting brackets and isolation grommets are provided. Cold Point Corp. backs the HW with a customer friendly one-year parts and labor warranty and five-year compressor warranty, (see Warranty document for details).


Fast and Easy Replacement

The Adirondack-Aire HW series zerOzone replacement chassis fit the existing space and ductwork without modifications. Because the chassis dimensions and construction details are like the original, replacement work is fast and easy. The unit installs without the need for water loop shut down or draining. Water, drain, hanger bracket, ductwork, and electrical connections line right up to the original installation. Using Adirondack-Aire replacements eliminates the need for room renovation, redecorating, ductwork and piping changes. The HW is the solution that gets your property back in service quickly and at the lowest total cost.

Damage Protection

The standard high-pressure switch and evaporator coil freeze protection stop unit operation before damage occurs, should airflow become reduced or obstructed due to dirty coils, obstructed airflow, motor failure or lock up. A freezestat protects the water coil from freeze damage due to water temperature or flow problems. The water coil is designed for low water-side pressure drop, eliminating potential pump sizing and water flow problems.
