Compressed Air Energy Audits
Our energy audits identify cost-saving opportunities in compressed air systems through pressure reduction and leak detection. Using advanced diagnostic tools, we provide actionable reports to enhance efficiency and reduce energy consumption by up to 7%. Tailored for businesses seeking long-term financial and environmental benefits.
Digital Air Leak Detection
This service pinpoints and quantifies air leaks using acoustic technology, reducing energy waste and CO2 emissions. Real-time data analysis enables immediate remedial action, while detailed reports prioritise repairs. Essential for maintaining system efficiency and minimising operational costs in industrial settings.
Planned Maintenance
Our planned maintenance ensures uninterrupted system performance with scheduled visits and genuine spare parts. The Guardian service plan offers 7-9 years of coverage, including SMARTLINK remote monitoring. Ideal for maximising uptime and extending equipment lifespan while adhering to manufacturer standards.
Breathing Air Quality Testing
We conduct EN 12021-compliant testing to ensure workplace breathing air safety. Regular assessments detect contaminants like carbon monoxide and oil vapour, preventing health risks. Critical for industries reliant on respiratory protection equipment and regulatory compliance in compressed air applications.
Compressed Air Pipe Installation
Specialising in AIRnet aluminium and stainless steel pipework, we design layouts minimising pressure loss. Systems are tailored to operational demands, ensuring efficient air distribution. Includes maintenance to prevent leaks and sustain energy efficiency across manufacturing and industrial environments.
