80/20 System

80/20 systems can be a variable make-up air unit, a total-building heat unit, or a combination of both. By recirculating air, this system provides the most efficient building heat system.

 

One unit can handle multiple and varying exhaust loads as a variable, make-up air unit using the 80/20 System. This system offers constant discharge airflow but varies the amount of outside air introduced to the building. With the use of the 403M or the 404M space-temperature control system, the unit can be a complete building heating system for either fixed or variable exhaust loads.

 

The 80/20 System supplies at least 20% outside air to the building and mixes with re-circulated room air at a maximum of 80%, without the return air re-circulated through the burner. A building-pressure switch controls the modulating-burner bypass and return-air dampers introducing more outside air as the building’s exhaust load changes. The varying exhaust-air loads automatically and continually adjust the amount of make-up air introduced into the system.

All Rupp Air direct fired systems are provided with terminals to integrate operation with the building exhaust system.
