Trane chm00781 Heat Absorbing Chemical 1 Qt

Product Description

The TRANE chm00781 is a thermo-trap heat absorbing liquid designed to mitigate heat transfer during service and maintenance work on HVAC systems. Applied to nearby components before soldering, brazing, or any heat-intensive procedure, it absorbs and dissipates thermal energy to protect valves, fittings, gaskets, and other heat-sensitive parts from damage. The formula is non-hazardous, water-soluble, and translucent in appearance. It meets OEM specifications and is packaged in a 1-quart spray bottle for easy, targeted application in the field. HVAC technicians and refrigeration service professionals are the primary installers.

This heat absorbing chemical is suited for residential and light commercial HVAC service applications where brazing or soldering is performed near components that cannot be removed from the line. It is particularly useful during refrigerant line repairs, coil replacements, and any service task where open-flame work must occur close to factory-installed fittings, expansion valves, or other thermally sensitive parts. The spray bottle format allows precise application in tight spaces common to air handler cabinets and rooftop unit service panels.

Key Features

• Absorbs and dissipates heat to protect nearby components during brazing and soldering
• Non-hazardous, water-soluble formula suitable for indoor service environments
• Translucent appearance allows visual confirmation of coverage
• Specific gravity of 1 at 60 degrees F indicates a water-like density for consistent application
• Packaged in a 1-quart spray bottle for field-ready, targeted use
• Manufactured to OEM specifications for consistent, repeatable performance

Compatibility

Designed as an OEM-style heat absorbing chemical for use during HVAC service and maintenance procedures requiring heat protection of adjacent components.

Installation Notes

This chemical is applied by licensed HVAC technicians prior to any open-flame work such as brazing or soldering. Shut off system power and isolate refrigerant circuits per standard lockout/tagout procedures before beginning service. Apply the liquid generously to surfaces requiring thermal protection and reapply as needed during extended heat exposure. Follow local fire codes and manufacturer safety data sheet guidelines when working with open flame in enclosed spaces.
