Features of PHOENIX AIR SYSTEMS™ Direct-Fired Heating, Cooling and Pressurization Systems

Make-Up Air (MUA)

• 100% replacement air with a fixed discharge air volume.
• Function: Supplies direct replacement air for building mechanical exhaust.
• Application: Used as make-up air for industrial processes which incorporate mechanical exhaust.

Air Management (AM)

• Design: Variable outdoor air from 20% to 100% and a modulating burner with a 30:1 turn-down ratio. Discharge air volume is fixed.
• Function: Automatically responds to building pressure and temperature needs.
• Application: Used in industrial and commercial buildings that have air quality and specific air management requirements.

Variable Air Volume (VAV)

• Design: 100% replacement air with variable discharge air volume from 25% to 100% of total capacity.
• Function: Provides efficient, low-cost heating where minimum ventilation rates are required.
• Application: Used in warehouses, distribution centers, retail outlets, etc.

Fixed Recirculation (FR)

• Design: Fixed 80% air turnover rate and 20% outdoor air replacement rate. Discharge air volume is fixed.
• Function: Provides efficient, low-cost heating where minimum ventilation rates are required.
• Application: Used in warehouses, distribution centers, retail outlets, etc.
