Pneumatics for the energy industry - high-temperature actuators
We design and manufacture pneumatic actuators, hydraulic cylinders and air preparation systems for power plants, heating plants and refineries. We specialise in high-temperature designs, ATEX versions and custom-engineered solutions for the most demanding site conditions.
Where does pneumatics operate in the energy industry?
In the energy industry, actuators control dampers, gate valves, throttle valves and valves in steam, water and gas systems. They operate at high temperatures, in dust and moisture, often in continuous duty. That is why they require different selection criteria than standard automation components.
- Power plants and combined heat and power plants: secondary air dampers (OFA/S-OFA), flue gas desulphurisation systems, start-up burner lances, throttle valves, steam flow control in turbines.
- Heating plants: water and gas flow control, burner control and throttle valve control in heat exchangers.
- Refineries and chemical installations: ball valve control in explosion hazard zones - ATEX designs, with no sparking risk.
High-temperature designs - our speciality
We design special actuators for secondary air dampers, OFA/S-OFA systems, flue gas desulphurisation systems and start-up burner lances so that they maintain stable operating time even at local temperatures above 150°C.

What we offer for the energy industry
High-temperature actuators
For OFA/S-OFA dampers, flue gas desulphurisation systems, throttle valves and turbines - with FKM/FFKM seals, PTFE/PEEK sliding elements and thermal shielding. Operation up to +150°C continuous and +210°C temporary.
Water-jacketed actuators
Versions with an additional water jacket for operation in very high-temperature zones - up to approximately 300°C.
Rodless actuators
Compact solutions with long stroke in a small installation space, used for example for start-up burner lances, such as D50x500.
Position-controlled actuators
With a positioner or a linear displacement transducer (BTL) - full control of damper and throttle valve opening, continuous regulation.
ATEX designs for EX zones
Actuators for refineries and gas installations controlling ball valves - no sparking, which minimises ignition risk.
Hydraulic cylinders
Hydraulic cylinders, including plunger cylinders, such as D380x1400 with VITON seals, for shut-off dampers and dedusting installations.
Key benefits of pneumatic drives in the energy industry
Safety
No sparking - solutions compatible with ATEX and EX zones, such as refineries and gas installations.
Reliability
Operation at high temperature, in moisture and dust - with proper material selection and thermal shielding.
Control precision
Double-acting actuators with a positioner or displacement transducer - continuous regulation and opening degree control.
Lower operating costs
Lower energy consumption than electric or hydraulic drives, simple design and easy service.

How to select an actuator for the energy industry?
- Application OFA/S-OFA damper, flue gas desulphurisation system, lance, throttle valve, ball valve or steam regulation - this determines the design.
- Operating temperature Local temperature and thermal gradient - they determine materials, shielding and possible water jacket requirements.
- Hazard zone Whether the application requires ATEX design, such as a refinery or gas installation.
- Force and stroke Piston diameter, stroke, loads and torque on the damper.
- Control and feedback Two-position or continuous regulation - positioner, BTL linear displacement transducer.
- Environment Dust, chemicals, moisture, anti-corrosion protection, for example C5-M class.

FAQ - pneumatics for the energy industry
What energy industry applications are your actuators used for?
They are used for secondary air dampers (OFA/S-OFA), flue gas desulphurisation systems, start-up burner lances, throttle valves, steam flow control in turbines, and valve control in steam, water and gas systems.
What temperature can high-temperature actuators withstand?
As standard, they operate up to +150°C continuously and up to +210°C temporarily. In the version with an additional water jacket, operation is possible up to approximately 300°C. We use FKM/FFKM seals, PTFE/PEEK sliding elements and thermal shielding.
Do you offer ATEX designs for refineries?
Yes. For explosion hazard zones, we offer non-sparking actuators used, among others, to control ball valves in chemical and gas installations. These designs are certified under the ATEX system by KOMAG.
Can the damper opening degree be controlled?
Yes. We use double-acting actuators with a positioner or a BTL linear displacement transducer, which enables continuous regulation and full control of the opening degree.
Do you manufacture hydraulic cylinders for the energy industry?
Yes. We manufacture hydraulic cylinders, including plunger cylinders, for example D380x1400 with VITON seals, used for shut-off dampers and in dedusting installations.
What warranty applies to your products?
