80/20 Pressurizing/Recirculating Direct-Fired Heating & Cooling System

Arizon’s 80/20 Pressurizing/Re-Circulating Indirect or Direct-Fired Heating and Cooling System provides customers with the benefits of building pressurization control and air re-circulating capabilities all in one unit. Available in a fixed or modulating control operation, Arizon’s system can re-circulate between 0 and 80% of the inside conditioned air in a building while pressure-controlling the space and providing between 20% and 100% fresh, outside air. By combining building pressurization and air re-circulation in one system, we prevent both unconditioned outside air from migrating into the space while continuously re-circulating the inside conditioned air to provide higher efficiency versus competitors 100% make-up air alternatives.
