"The proprietary technologies we have in ETS, deliver electrification solutions at scale within a broad range of critical industries and applications. These also provide new ways for customers to maintain their existing operating processes* while also achieving their net zero aims. This applies to the solutions we provide directly as ETS as well as the TargetZero solutions, deployed by Steam Thermal Solutions, which decarbonise* the raising of steam."


Armando R. Pazos

Lowering emissions and delivering efficiencies

We create electrical process heating and temperature management solutions, including industrial heaters and systems, heat tracing and a range of component technologies.

Our electrical process heating and temperature management solutions improve process efficiency through better thermal energy management and control systems.

Electrical heating solutions are a complementary medium to steam and there are synergies with the broad industrial and geographical application.

They are easy to incorporate, install, maintain and control and can have zero emissions at point of use, making them a sustainable choice.

Our solutions excel in applications that require rapid ‘on-off’ control, higher temperatures and concentrated power loads as well as in an increasing range of sustainable applications where decarbonisation of industrial processes is a key driver.

How we support oil and gas producers to reduce CO2 emissions

Chromalox, part of ETS, is helping to reduce carbon emissions in the exploration and production facilities of a major energy company in the USA. Using our innovative Medium Voltage technology, we retrofitted electric immersion heaters into heater-treaters to replace the gas-fired element, conducting the operation on site to minimise expensive asset downtime and providing a zero-emission solution when supplied with renewable energy. Heater-treaters are critical to processes in the global energy industry and Chromalox is reaching more operators in the sector to help them decarbonise this key equipment.
