ILAHP Inverter Extreme Air-to-Water Heat Pump
Benets and Features
Inverter Compressor
ILAHP Inverter Extreme Heat Pump uses Inverter technology to
precisely match the heating or cooling load.
Advanced Controls
Unit function is managed by a parametric microprocessor allowing
on site adjustment to match specific operating requirements.
Easy Installation
The monobloc configuration keeps all refrigerant outdoors with
no refrigeration connection or handling done on site. Only the
water/antifreeze mixture is plumbed indoors.
Quiet Operation
The insulated housing, advanced fan profile, and variable speed
fan and compressor all combine to achieve a low noise level of
47dBA to 57dBA @ 3 meters.
Efficient Energy Transfer
ILAHP Inverter Extreme heat pump is equipped with high
efficiency, large surface area energy exchangers for both the air
to refrigerant heat transfer and the refrigerant to water energy
transfer.
Low Ambient Temperature Cooling Operation
ILAHP Inverter Extreme heat pump is capable of operating in
cooling mode in ambient temperatures as low as 5°F.
Enhanced Vapor Injection
Compressor and refrigeration system are optimized for efficient
and powerful heating performance in ambient temperatures as
low as -22°F (-30°C).

Typical System Diagram
*Autoll system is suggested but not required by SpacePak. If such installation is desired or required by local code, the
Autoll MUST draw from a reservoir of pre-mixed glycol/water solution. Filling directly from a well or municipal water
source may introduce contaminants and will dilute the glycol solution in the event of a system leak.
This may impact warranty coverage.
