The Cold-Environment Pneumatic Actuator (-50°C) is a type of actuator specially designed to operate in low temperatures. It is manufactured to function reliably under extreme weather conditions down to -50°C. These actuators are mechanical systems that operate with compressed air and provide rotary motion. They are used in environments where conventional pneumatic systems cannot operate.

Standard actuators may experience freezing, seal failure, and performance loss. However, these products can be safely used even at temperatures as low as -50°C. The seals and materials used in their internal structure are selected to withstand low temperatures. This eliminates the risk of freezing and ensures long-lasting performance.

Cold-resistant pneumatic actuators are generally preferred in polar regions, high-altitude locations, or open-field facilities.

Where to use?

These specialized actuators are used in cold-region facilities such as power plants, LNG terminals, and refineries. They provide ideal solutions for controlling valves located outdoors. They are also preferred in water treatment and natural gas plants operating under winter conditions.

In industrial systems, it eliminates the risks posed by snow and ice. It is critically important for the safety and continuity of the system. With its structure providing stable operation down to -50°C, it offers full protection against harsh climatic conditions.

In addition, it can operate in integration with double-acting pneumatic actuators and 120° rotary models.

What Are the Technical Specifications?

UNOX cold-climate pneumatic actuators feature an aluminum extrusion body and are resistant to external effects. The internal surfaces are specially treated to minimize the coefficient of friction. The pistons are made of aluminum casting material and provide high efficiency with their symmetrical design.

The shaft is made of cadmium-plated steel and is resistant to high torque. Special nitrile rubber seals, which maintain their elasticity even at -50°C, are used for leak prevention. All mounting dimensions comply with ISO 5211 and VDI/VDE 3845 standards, allowing the actuator to be easily adapted to a wide range of valve types.

It can be supported with accessories such as switch boxes, directional valves, and solenoids as auxiliary components.

Why Should This Product Be Preferred?

In extremely cold regions, the safety and operability of systems are of great importance. While standard products carry a risk of failure due to freezing, this product can operate safely for extended periods. In addition, it requires minimal maintenance and offers high energy efficiency.

It is an ideal choice for businesses seeking a reliable solution in harsh field conditions. UNOX-branded locally manufactured models offer both high quality and cost-effectiveness. For more information and similar products, the UNOX Actuator Category can be visited.
