We serve industries such as oil & gas, chemicals, food & beverage, and water treatment, offering tailored, compliant, and energy-efficient solutions.

Why Is a Heat Loss Calculation Important?

Uncontrolled heat loss can lead to:

• Temperature instability
• Higher energy consumption
• Reduced system efficiency and safety risks

What Is a Heat Loss Calculation?

A heat loss calculation determines the rate at which heat escapes from a system to its surrounding environment. Key factors include:

✅ Material composition
✅ Surface area exposure
✅ Ambient and internal temperatures
✅ Insulation properties
✅ Environmental conditions (e.g., wind, humidity, altitude)

Our heat loss calculation services include:

IBC & Drum Heating
Maintain optimal temperatures for viscous fluids such as bitumen, oils, and chemicals — preventing crystallisation or degradation.

Pipework & Valve Trace Heating
Protect pipelines from freezing and maintain flow during cold conditions.

Tank & Vessel Heating
Ensure critical storage tank temperatures in sectors like food processing, pharmaceuticals, and petrochemicals.

Hazardous Area Heating
ATEX/IECEx certified heat tracing for safe operation in explosive gas and dust environments.
