Mestek 1144135000 Infrared Heater Body Package 75000 Btu/h

Product Description

The MESTEK 1144135000 is a 20-foot infrared heater body package rated at 75,000 BTU/h, designed for use with the RSS Series radiant tube heating systems. This package includes all major structural and combustion components needed for a complete body assembly: one 12-hole flanged aluminized steel combustion chamber, one hot rolled steel heat exchanger with reflectors, couplings, brackets, hangers, and a body fastener kit. It is intended for installation by licensed HVAC or mechanical contractors working on commercial or industrial radiant heating applications.

This body package is suited for large open spaces such as warehouses, manufacturing facilities, garages, and agricultural buildings where radiant tube heating is the preferred method of space conditioning. The 20-foot assembly length covers substantial linear runs, and the included hardware simplifies field installation. The package is rated for use with RSS Series units in the 40- to 75,000 BTU/h range, making it appropriate for mid- to higher-capacity radiant heating configurations.

Key Features

• Complete 20-foot body package with all structural and combustion components included
• 12-hole flanged aluminized steel combustion chamber for corrosion resistance and durability
• Hot rolled steel heat exchanger with reflectors for directed radiant output
• Includes couplings, brackets, hangers, and body fastener kit for a self-contained installation

Installation Notes

Installation should be performed by a licensed HVAC or mechanical contractor familiar with gas-fired radiant tube heating systems. Shut off all gas and electrical supply to the heater before beginning any service or assembly work. Ensure all hangers and brackets are secured to structural members capable of supporting the full assembly weight, and verify clearances to combustibles comply with the manufacturer specifications and applicable mechanical codes such as the IFGC.
