How AUMA actuators drive energy efficiency in chemical plants

Published: 28th April 2025 | Issue 98

AUMA Actuators Limited’s advanced range of electric actuators provides a transformative solution in the chemical industry, where operational efficiency and sustainability are paramount, delivering tangible energy and cost savings while enhancing operational reliability.

Chemical plants require precise flow control, often relying on valve automation to regulate the movement of gases, liquids, and other process media. Traditional mechanical and pneumatic actuation systems can be energy-intensive and costly to maintain.

Paul Hopkins, Managing Director of AUMA Actuators Limited, explains: "At AUMA, we are committed to providing solutions that enhance operational efficiency and drive sustainability. Our electric actuators offer chemical plants a smarter way to reduce energy consumption, cut costs, and improve reliability, helping them meet both economic and environmental goals."

AUMA’s comprehensive range of electric actuators eliminates the need for compressed air, a common source of inefficiency in chemical plants. Pneumatic systems rely on compressors, which consume significant energy to generate the necessary air pressure. Leaks and inefficiencies in compressed air networks can lead to energy losses of up to 30%¹, increasing operational costs. AUMA’s electric actuators reduce energy consumption, leading to a lower carbon footprint and cost savings.

AUMA actuators also incorporate intelligent control features that optimise energy usage. Precise torque and position control ensure that valves operate only when necessary, reducing unnecessary energy expenditure. The integration of variable-speed drives also enables smooth start-stop operations, preventing energy spikes and extending equipment longevity in service.

The shift from pneumatic to electric actuation reduces energy costs and lowers overall maintenance expenses. Pneumatic systems require regular servicing, including the maintenance of compressors, filters, and air lines, all of which contribute to ongoing operational expenditures. In contrast, AUMA’s electric actuators have fewer moving parts and are designed for extended service intervals, reducing downtime and maintenance costs.

AUMA’s modular actuator design allows for easy upgrades and component replacements, further enhancing long-term value. The ability to integrate with modern digital control systems means that chemical plant operators can benefit from predictive maintenance, avoiding unexpected failures, whilst optimising asset management strategies.

AUMA’s electric actuators support environmental objectives by reducing CO₂ emissions associated with energy-intensive pneumatic systems, contributing positively to the increasing focus on sustainability across the global chemical sector. The efficiency gains also contribute to regulatory compliance, helping plants meet stringent energy efficiency and emissions targets.

As chemical plants continue to modernise, the adoption of AUMA’s electric actuators presents a compelling opportunity to enhance process efficiency, cut costs, and support sustainability initiatives. AUMA’s solutions are paving the way for a more efficient and environmentally responsible chemical industry by controlling energy waste, reducing maintenance, and enabling smarter process control.

For example, the Air Infiltration and Ventilation Centre (AIVC) notes that duct leakage can severely impact the energy efficiency of systems that include air heating or cooling. en.wikipedia.org
