RGSP SERIES

90% Temperature Efficiency (+/- 5%)

RGSP Series units are ideal for small commercial and residential applications. Their compact size and configuration make them ideal for small mechanical rooms, or crawl spaces. Units can be mounted vertically, horizontally on the side, or horizontally on the back.

DUAL CORE T M TECHNOLOGY

RGSP Operation

Design Considerations

Due to the Dual Core’s fast acting damper design, cross leakage rates are less than 1-3% which is well under ASHRAE 62 -2004 prescribed acceptable cross leakage rates for energy recovery applications. Consult your local approval agency to ensure they will allow ASHRAE’s recommendation.

When choosing a location for the unit, ensure that the duct length for outside/exhaust air is as short as possible. When the cycles switch, the exhaust air in the duct will be drawn back into the outside air. Cross leakage is less than 1-3%, but will increase with longer outside air duct runs.

Ensure ducting for outside/exhaust air is designed to handle the switching positive and negative pressures. These ducts will experience alternating positive and negative pressures every 60 seconds.

The supply air and exhaust air duct work (to the unit) must be well insulated to assure maximum heat recovery is attained. Insulating outside air ducts located in non-heated areas is not necessary.

Phase 1

Exhaust air passes through Core A, where Core A will absorb energy from the exhaust air stream. Simultaneously, Core B is adding energy to the supply air stream.

Phase 2

Once the damper flips, Core A is adding energy to the supply air stream, while Core B is absorbing energy from the exhaust air stream “recharging” Core B, and preparing it for the next cycle.

These phases will cycle every 60 seconds, constantly delivering extremely high energy recovery, frost free!
