Indirect-Fired Outdoor Make-Up Air
Indirect-fired outdoor heating and make-up air systems are designed and engineered to deliver superior performance in a variety of applications. The unit is constructed of a weatherproof duct furnace with a blower, and optional cooling and/or downturn plenum section designed for use with a building’s heating, heating/ventilation/cooling make-up air system.
- Available in 17 model sizes with input ranges from 75,000 to 1,200,000 Btu/Hr.
- Airflow ranges from 556 to 14,500 CFM
- Natural or propane gas
- All units a minimum of 81% thermally efficient
- 20°-100°F air-temperature
- ETL certified
- Superior corrosion resistance and extended equipment life with 18-gauge, polyester-powder paint on an aluminized steel casing
- Blower and motor vibration isolation
- Blower performance up to 3.0” W.C. is perfect for longer ductwork or accessories with high-pressure drops
- Quick and accurate field connections with separate line and low-voltage terminal strips with job specific wiring diagrams
- UL60335 Compliant
- 409 stainless steel heat exchanger, burner, and drip pan
- Two-stage and electronic modulation controls
- Modine Control System option provides a programmable microprocessor controller with building management compatibility
- High and/or low gas pressure switches
- Ultra-low leak class-I leakage resistance outside air dampers
- Two position, modulating, or floating building pressure control damper actuators maximizes control of outside ventilation air with fresh and return air dampers
- Variable frequency drives for maximum air volume control flexibility
- Factory-installed DX or chilled water coil
- Dead-front disconnect switches
- Double-wall construction for the blower and/or cooling cabinet
- Circuit analyzers minimize start-up and service time by immediately identifying causes of improper unit operation
- Smoke detectors, timed freeze protection, thermostats, time clocks, and many other control devices
- Roof curb and supply and/or return duct connectors to allow ductwork be field installed before unit arrives at the job site
