IHR Series

High-Intensity Indoor Gas-Fired Infrared Heater

The Modine IHR High-Intensity Infrared Heater Series is engineered to deliver concentrated, gas-fired radiant heat in industrial and commercial environments with high ceilings and demanding heating requirements. Unlike conventional forced-air systems that heat large volumes of air, the IHR Series emits infrared energy that directly warms floors, equipment, and occupants, providing rapid comfort where it is needed most.

Designed for high-bay applications, the IHR Series is well-suited for facilities that require spot heating, zoned comfort control, or fast recovery in cold environments. The high-intensity infrared design allows for effective heating even in spaces with air movement, open doors, or intermittent occupancy.

Models

  • IHR – High-Intensity Infrared Heater (30,000 to 160,000 BTU)

Highlighted Features

High-Bay Performance

Designed for mounting heights typical of warehouses, manufacturing plants, and industrial facilities.

High-Intensity Radiant Heat

Concentrated infrared energy delivers fast, targeted heat to people and surfaces below.

Fuel-Efficient Zonal Heating

Radiant heat minimizes air stratification and reduces wasted energy in large spaces.

Product Details & Specifications

Key Features

High-Temperature Cordierite-Based Grooved Ceramic Tiles: Designed with perforations on both the top and bottom of the grooves to enhance temperature control and surface area, optimizing heat transfer while maintaining lower gas input ratings.

Polished Aluminum Reflectors: Efficiently direct radiant heat to specific areas, improving comfort over larger spaces.

16-Gauge Aluminized Steel Frame: Durable construction provides sturdy support for easy chain mounting.

Fanless Design: Eliminates noise, drafts, and maintenance, while also reducing electrical energy costs.

Wide Input Range: Available from 30,000 Btu/hr to 160,000 Btu/hr, suitable for a wide range of heating requirements.

Flexible Ignition Options: Features direct-spark or self-energizing standing-pilot ignition for maximum application versatility.

115V and 25V Controls: Accommodates a wide range of electrical inputs.

Externally-Mounted Controls: Allow easy access to the gas valve, control system, transformer, and gas orifices, simplifying installation and maintenance.

Easy Burner Replacement: Burners can be replaced by removing just one fastener, negating the need to remove the unit from its mounted position for servicing.

CSA Design Certification: Ensures conformity to national safety standards for indoor, unvented operation in commercial and industrial applications.
