RTL Chassis Series

RTL Chassis picture

The Adirondack-Aire RTL Series zerOzone replacement chassis provides environment friendly, high efficiency cooling and heating where individual, quiet control is a priority. This application flexible unit is a direct replacement for Zehnder/Rittling VHCH series vertical stacked water source heat pump chassis. The chassis is a part of a complete system, which consists of the chassis, blower section, control box, and furred-in room cabinet with risers. The chassis contains the compressor, air side heat exchanger, water side heat exchanger, and refrigerant circuit control and safety components. Also included is the C

ontrol Conversion kit. Blower applications with PSC motors may be field converted, blower applications with EC motors must be replaced.

The RTL is dimensionally identical to the original for a fast, easy, and trouble free-installation. Quality components, careful design and testing and the latest in environment friendly technology means long unit life, user satisfaction, and lower energy costs. Consider the extensive list of standard features which includes: stainless s

teel drain pan, refrigerant circuit access ports, double insulation compressor mounting, water coil freezestat, and high-pressure over protection. Adirondack-Aire is the replacement solution the competition can't match. Cold Point Corp. backs the RTL 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 RTL series zerOzone replacement chassis fits the existing Zehnder/Rittling room cabinets and works with the existing blower section and control box without modification. Because the chassis dimensions and construction details are like the original unit, replacement work is fast and easy. The chassis installs without the need for water loop shut down or draining. Water and drain connections line right up to the original installation. The electrical connectors plug directly into the control box connectors. A chassis pull handle is provided to facilitate easy removal and handling. Using Adirondack-Aire replacements eliminate the need for room renovation, redecorating, and piping changes. The RTL chassis is the solution to get 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, or 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.
