Direct-Fired Indoor/Outdoor Make-up Air - Modine HVAC

Direct-Fired Indoor/Outdoor Make-up Air

Direct-Fired Indoor/Outdoor Make-up Air

Ideal for applications that require 100% outside air, the direct-fired make-up air unit is the perfect fit.  This unit provides excellent efficiency with 100% thermal efficiency and 92% sensible cooling.

By directly heating the make-up air by a gas flame, the need for a heat exchanger is eliminated, as well as the efficiency loss that goes with it.  It is designed to provide value through best-in-class features to simplify installation and reduce maintenance costs.


Modine Model MCV/MVV

  • Auto-Velocity profile system on every unit continuously monitors burner profile pressure drop and automatically adjusts burner air velocity for optimum combustion.
  • Direct Spark Ignition (DSI) to simplify operation and minimize cost on units rated 1125MBH and smaller.
  • Factory assembled natural or propane gas manifolds.
  • Low-maintenance aluminum cast burner with stainless steel mixing plates and 30:1 turndown capability.
  • Foil-faced insulation on the cabinet for ease of cleaning.
  • Standard Neoprene vibration isolation blower and motor for quiet operation.
  • Prewired 10-foot power and control wire harness in flexible conduit for speed and ease of field wiring. Wires are labeled for easy identification on each job-specific wiring diagram.
  • Floor-mounted wiring chase to eliminate the need to drill holes in the floor for routing electrical wiring harnesses to the space.
