Small Duct High Velocity
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.

High Velocity Air Handlers

- Multiple configurations for all types and size applications including R410A, heat pumps and hydronic coils.
- Fully insulated and durable “E-Coat” finished cabinet for ultra quiet operation and superior longevity.
- Low-profile horizontal or vertical design for application flexibility. Fits in tight spaces including attics, basements, closets, crawl-spaces and garages.
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.

The basic difference between SpacePak and other air conditioning systems is the way SpacePak actively circulates air within the room and throughout the structure’s entire living/working space. Circulating the air more effectively is what makes a home with SpacePak central air so uniformly comfortable: no cold or warm spots, no drafts, and up to 30% more humidity removed.Conventional central air systems merely drop cold air in at the ceiling; the distribution of cool air is haphazard, leading to over-cooling in some spots or drafts in others.
While every installation is configured specially to the individual home’s unique requirements, fundamentally the SpacePak system consists of the following components as labeled in the diagram below. Each one is briefly described below.
