DIRECT-FIRED MAKE-UP AIR UNITS
Request Catalog 5-160 For Complete Technical Information and Specifications.
Modine has developed the best in direct-fired, make-up-air units - the MDB (Single and Two
Speed 100% Make-Up Air) and MRB (Fresh and Return Air). These units are designed to
provide an economical and efficient means of supplying tempered make-up air to a space
or building. Available in eight airflow configurations, the units cover a wide variety of
applications.
Standard Features:
•100% thermal efficiency (92% sensible) results in lower fuel bills.
•Units are designed for indoor or outdoor mounting, providing flexibility in applications or
design, as well as simplifying installation.
•Natural or propane gas manifolds are factory-assembled to provide flexible fuel options
and to reduce field-installation, start-up costs and problems.
•Factory-wired electrical panel with numbered terminals significantly reduces start-up delays.
•100% factory flame-testing eliminates the majority of field start-up problems caused by
defective controls.
•Weatherproof roof with drip ledge provides protection from water being drawn into the
unit from the roof.
•18-gauge galvanized steel casing provides high corrosion protection for long life.
•Adjustable drives through 10 HP simplify air balancing and eliminates the need to
change drives.
•Four access doors provide maximum access for easy adjustments and service.
•22:1 firing rate turndown for optimum temperature control.
Optional Features:
•V-bank filter section
•Inlet hood
•Inlet damper
•Discharge damper
•Evaporative cooling
•IRI and FM manifold arrangements
•Discharge air temperature control, space temperature control, or building management
(0-10 Vdc or 4-20 mA input) control
•High and low gas pressure switches
•Internal blower and motor vibration isolation
•Acrylic paint finish on exterior casing parts
•ETL Certified •Btu/Hr Outputs from 42,000 to 7,862,000 •CFM Ranges from 1,600 to 60,000
•100% Make-Up Air and Recirculating Configurations • 100% Thermal Efficiency • Designed for Indoor
or Outdoor Mounting •Factory-Assembled Natural or Propane Gas Manifolds
