Time-Saving Essentials for Working in Low Temperatures
Specialists who work in challenging conditions, especially offshore professionals, often turn to us for equipment advice. This means we hear their feedback on the products available on an almost daily basis.
One product they consistently praise is our SA FLEXIHEAT EX Heating Jackets and SA FLEXIHEAT High Power Heating Jackets for pipes, valves, pumps and other applications.
That’s because, in demanding work environments where every minute counts, the jackets prevent solidification almost immediately after being fitted.
Both versions keep essential equipment, such as compressors and pumps, operational even at temperatures as low as -40°C (or -50°C with the high-power jacket), enabling maintenance work to proceed with fewer delays.

Pipe Heating Jackets
A choice between two ATEX and IECEx certified jackets means an ideal version is available for any low temperature environment.
The SA FLEXIHEAT EX Pipe Heating Jackets and SA FLEXIHEAT High Power Heating Jackets are both feature-packed:
- ATEX and IECEx certified for Zones 1 and 2 (gas), 21 and 22 (dust)
- Tough and durable
- Highly portable and lightweight
- Rapid and easy to install
- Different size options: 400mm, 700mm and 1,000mm (narrow)
- Self-regulating heat output
- Allows for virtually any sized pipe or application
- Suitable for straight or curved areas
- Linkable
Both heating jackets are highly portable & lightweight, making it extremely easy to quickly assemble them onto any pipework to take immediate effect.
No additional equipment is needed for the pipe heaters to function, they can simply be plugged in and will start working straight away: saving money and valuable time on-site.
However, both the EX Heating Jacket and the EX High Power Heating Jackets have some important differences.
SA FLEXIHEAT EX Pipe Heating Jackets
The SA FLEXIHEAT EX Pipe Heating Jackets operate effectively in temperatures as low as -40°C and come in both 110V and 230V versions. These jackets provide a safe, efficient, and fast alternative to costly and complicated heating systems.
Ideal for situations where trace heating is impractical or difficult to install, the heating jackets quickly and easily wrap around areas prone to waxing or solidification due to low temperatures—and can be installed by a single worker in seconds.
FLEXIHEAT EX High Power Heating Jacket
The FLEXIHEAT EX High Power Heating Jacket is designed for temperatures as low as -50°C and is available in a 230V version. This high-powered jacket offers safe and reliable temporary frost protection and maintenance for process equipment.

Its flexible design allows for quick and easy installation, significantly reducing maintenance and installation costs. Additionally, the jackets feature both input and output cables, enabling connection between multiple jackets to insulate larger areas efficiently.
