Maintenance and Installation Features
The EZ Series VP units are designed for individually-zoned comfort controlled heating and cooling. The unit is an industry standard of 23 1/8” wide by 23 1/8” deep by 31” high. We offer our cooling chassis to operate with cooling only or heat pump with back up electric heat. The design standards, heavy duty construction and the focus on indoor noise reduction have positioned our unit as the premier unit of the future. Standard warranty is a one year parts and labor including a five year compressor part only warranty or a two year parts only including a five year compressor part only warranty.
Available in cooling-only and cooling plus heat pump models.

Recycling/reusing Dr. PTAC in secondary market where the "first costs" are prohibitive to owners
The Dr. PTAC system is an add on system to our standard PTAC unit to provide conditioned makeup air into a space through the PTAC unit by providing 55 CFM of outdoor air 24/7 by forced fan and cycling dehumidifier compressor based on outdoor relative humidity levels.
Dr. PTAC was created to solve issues with dehumidification in rooms and to introduce fresh air due to deficiencies of oxygen levels. Dr. PTAC is not only a PTAC but a Conditioned Make Up Air unit. New ASHRAE studies show that many illnesses in hotel rooms can be attributed to oxygen deficient atmospheres. Dr. PTAC solves that issue by introducing tempered conditioned make up air that satisfies both humidity level introduction and supplied oxygen.
Dr. PTAC is a two stage system. The primary unit is responsible for control of Sensible Heat that is introduced into the room via make up air temperature and occupant thermal load. The secondary unit is primarily a dehumidification unit that provides 55 CFM of outside fresh air into the room. The correction of the sensible temperature comes from the main PTAC unit which provides additional dehumidification with temperature correction. Overall unit efficiency improvement over standard PTACs is approximately 3%. The compressor/dehumidification process is controlled by a humidistat (factory set at 50% RH) which is monitoring the outdoor relative humidity level and is adjustable by a qualified servicer. When the outdoor humidity level raises above 50% RH the compressor and dehumidification process starts. Below 50% RH compressor operation and dehumidification is stopped, however, fan operation continues to provide 55 CFM of outdoor air into the space.
The dehumidification system has a temperature switch which is monitoring both the refrigeration and the outdoor air temperatures. If the outdoor air goes below 38°F the compressor is disabled with fan operation continuing to provide outdoor air into the space. All dehumidifier controls and safeties are automatically reset. An optional air tempering heater is available for the fresh air system for applications where operation in cold winter climates is required. Condensate from the dehumidifier drains into the PTAC drain pan, where it is then also slung onto the condenser coil for re-evaporation outside when the A/C runs. Excess condensate is drained into the wall case which can then either drain to the outside through the louver OR piped to a drainage system via the optional drain kit.
