Refrigerant piping requires less space than traditional ductwork, allowing greater design flexibility.
The refrigerant flow rate varies through the lines with the use of an inverter compressor and electronic expansion valves, which modulate to match the load variations as individual rooms require more or less heating/cooling.
Configured as a 3-pipe heat recovery system.
Configured as a 2-pipe heat pump system.
Compressor efficiency is optimized through meticulous attention to the design details of the release valve and orbiting scroll.When synchronized, our compressor maximizes output while minimizing power consumption. The lifting force of the rotating scroll and release tension of the valve have been balanced to limit over compression while minimizing loss through leakage.
This fine tuning of the valve and scroll help make our IEER and SCHE ratings among the highest of all VRF systems in the industry.
An inverter is a variable speed drive that changes the electrical frequency being fed to a motor.
When this technology is applied to a compressor’s motor, the air conditioning systems operating capacity can be adjusted.
A variable speed compressor consists of an inverter and compressor. The inverter converts incoming alternating current (AC) to direct current (DC).
It then uses pulse width modulation (PWM) to produce AC to a desired frequency. This frequency is used to drive the speed of the compressor motor.
The cooling and heating can be varied depending on a number of inputs such as outdoor or indoor air temperature and humidity, set point, occupancy, etc.

A heat recovery system offers high energy-saving efficiency by drawing heat from the rooms to be cooled, and effectively using it as a heat source for the rooms to be heated.
Only currently occupied areas of the building are maintained at comfortable levels.
With our advanced control system and heat recovery units working together, each zone is comfortable and the transition from heating to cooling is efficient.
Consider an office building, at 3:30 in the afternoon on a 55 degree day, but very sunny.
On the west side of the building, the sun is shining, warming the space to the point that it could use some air conditioning.
The east side of the building is in the shade, cold, and needing heat from the VRF system.
With the heat recovery VRF system, heat is taken from the west side of the building (thus cooling it down) and moved to the east side of the building.
Because the outdoor unit isn't required to use the compressor to generate the heating (east side) or cooling (west side) efficiency is extremely high.
- tailored to any building
- System engineered to meet your building's diversity
Available for heat pump or heat recovery applications
With an air outlet kit, the unit can be installed inside the building
Extended piping limits increase flexibility and save cost.
Outdoor units can connect with multiple indoor units in various styles.
