SpacePak makes it possible to install central heating and cooling in any home or small business; regardless of structure design, age, size or type of construction. SpacePak is an air distribution system which uses a principle known as aspiration - as the air stream enters the room, it creates a gentle mixing of air in the room to provide thorough, comfortable draft-free air circulation. SpacePak eliminates stratification with a minimum floor-to-ceiling temperature difference.
Below is a list of climate control products offered by SpacePak with a brief overview of capabilities and features. Also listed is any related literature. Click on the titles for more information (where available) or download the appropriate literature.

Chiller Series - Reverse Cycle Heat Pumps
Chiller Series heat pumps work similar to conventional heat pumps by circulating refrigerant, which vaporizes at a low temperature in its enclosed evaporator producing additional energy in the process. Further concentration of the conditioned warm vapor occurs in SpacePak's dual programmable compressor raising it to a temperature where it can be circulated through a matching SpacePak WCSP air handler for distribution to the occupied space.
- Dual Programmable Compressor
- Simple Piping & Pumping
- Easily Zoned
- 30% larger condenser coil than traditional units
- Self Diagnostic Control - Factory Programmed
- Low AMP requirements
- Simplified installation & ease of service
- Quiet Operation - "Soft Start" package standard
- Highest R-410A COP and EER
- No Refrigerant Handling
- Refrigerant stay outside the building
- Low ambient antifreeze protection
- Manual J Load Calculation
