Industrial Thermal Coating
Better Heat Transfer. Stronger Protection. Longer Equipment Life.
The Hidden Efficiency Loss in Industrial Equipment
In industrial plants, heat exchangers and cooling systems are critical to production stability and energy efficiency.
Yet over time, industrial heat-transfer equipment quietly loses performance due to:
- Corrosion and oxidation of metal surfaces
- Fouling, scaling, and contamination from process fluids
- Surface roughening and pitting that reduce effective heat-transfer area
- Moisture retention that accelerates corrosion and thermal resistance
Even when equipment is still operating, these issues lead to higher energy consumption, unstable process temperatures, increased maintenance, and unplanned downtime.
In many cases, the problem is not system design—it is degraded heat-exchange surfaces.
What Industrial Operators and Asset Owners Want
As plant owners and operators, you want:
- Improved heat-transfer efficiency without equipment replacement
- Lower energy and operating costs (OPEX)
- Protection against corrosion in harsh industrial environments
- Extended asset life and deferred capital expenditure (CAPEX)
- Solutions that can be applied on existing equipment with minimal disruption
You need a solution that restores thermal performance and surface protection at the same time.

How Radiant+ Coating System Works
Radiant+ E3 restores and enhances industrial heat transfer by improving all three key mechanisms:
Conduction
Corrosion layers and fouling act as thermal bottlenecks.
Radiant+ E3 Coating forms an ultra-thin (10–15 micron) thermally conductive layer that restores efficient heat flow from:
process fluid → metal surface → cooling medium
This allows systems to achieve the same heat duty with lower energy input.
Convection
Rough, degraded surfaces increase resistance to fluid or airflow.
Radiant+ E3:
- Smooths surface roughness caused by corrosion
- Reduces boundary-layer resistance
- Slows future fouling build-up
This results in improved heat-transfer coefficients and reduced pump, fan, or compressor load.
Hydrophobic Protection
Water films and trapped moisture reduce heat transfer and accelerate corrosion.
Radiant+ E3 creates a super-hydrophobic surface that sheds moisture quickly, keeping heat-exchange surfaces thermally efficient and better protected over time.
Radiant+ E3 Coating Heat Transfer Capability Tests
Heatsink Test of Heat Transfer Capability (Same heat sink size)
The TIMPAD temperature under coated heatsink is significantly lower than TIMPAD temperature under bare heatsink.
Coated heatsink dissipate heats significantly better than bare heatsink.
Heatsink Miniaturization Test
TIMPAD temperature under coated but shorter heatsink is close to TIMPAD temperature under bare heatsink (despite of half-fin lenght-heatsink). Even lower with slight airflow.
Coated smaller heatsink allows miniaturization of heatsinkHow Radiant+ E3 Coating Hydrophobicity Test

Why Better Heat Transfer Means Lower Industrial Energy Use
When heat transfer improves:
- Required temperature differentials decrease
- Pumps, fans, and compressors operate at lower loads
- Process temperatures stabilise
- Mechanical stress and thermal cycling are reduced
This leads directly to:
- Lower operating costs
- Improved reliability
- Longer equipment lifespan
- Reduced unplanned downtime
Independent testing and thermal imaging confirm restored efficiency and faster heat rejection after Radiant+ E3 application .
