Islandaire VTAC



Islandaire now manufactures vertical thru-the-wall air conditioner and heat pump units (VTACs & VTHPs)! These Islandaire VTACs & VTHPs can be used for direct replacement of Amana, GE and Friedrich vertical units or for new construction projects. VTACs are available with the DR.PTAC option!

Cooling from: 8900-17500 Btu
Heating: 8500-16500 Btu

Comfort & Dehumidification

  • Quiet operation
  • Separate thermostat settings (limiting) for cooling and heating nodes
  • Samples the room temperature in intervals to monitor and maintain desired temperature
  • Optional constant fan mode for additional comfort options
  • Compatible with most smart remote thermostat systems

Sound Reduction Technology

  • New 2-motor design allows the indoor motor to run at slower speeds, which reduces indoor sound levels
  • The quiet, efficient compressor is mounted on vibration isolators, which absorb vibration-causing noise
  • Permanently lubricated motors reduce noise
  • Blower fan design moves air over a wider area so it’s quieter

Commercial Grade Construction

  • Islandaire’s advanced anti-corrosion protection protects the outdoor coil against deterioration and extends unit life, especially in harsh coastal environments
  • Front cover system attaches securely with optional locking mechanism
  • Room Freeze Protection initiates heat if room temperature falls to 40 °F in an unoccupied room
  • Various overloads protect electrical systems
  • Stainless Steel endplates on both indoor and outdoor coil
  • Indoor coil frost sensor protects the compressor
  • Durable front panel with break-proof control door and design
  • Permanently lubricated fan motors
  • Tamper-resistant grille
  • Durable, powder coat paint finish

The Dr. PTAC System

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.
