Thermal-XR

High-emissivity coating for heat exchange

Thermal-XR is a surface coating that dramatically improves radiative heat rejection from metal surfaces. For HVAC and refrigeration systems, that means better condenser performance, lower compressor head pressure, and measurable electricity savings—without replacing your equipment.

Emissivity that changes the equation

Emissivity measures how effectively a surface radiates heat. Thermal-XR achieves an emissivity index of 1.0—near the theoretical maximum for radiative heat transfer.

Compare that to typical bare metal surfaces used in heat exchangers:

Bare polished aluminium: 0.04–0.09
Copper: 0.03–0.05

A metal surface coated with Thermal-XR delivers 8.6× more radiative heat rejection from the same surface area—turning underperforming condenser fins into far more effective heat radiators.

How it improves system efficiency

Better condenser heat rejection. Coated surfaces radiate heat away faster, improving condenser efficiency under load.
Lower compressor head pressure. As the condenser rejects heat more effectively, discharge pressure drops—reducing strain on the compressor.
Lower electricity consumption. Field results show compressor electricity savings of 8%–16% or more, depending on system configuration and operating conditions.

Built for harsh environments

Thermal-XR has been tested for salt spray corrosion resistance up to 20,000 hours to date—making it suitable for coastal, industrial, and mining applications where equipment faces aggressive conditions.
