In the heart of Rotherham, a global engineering firm is demonstrating how sustainability and innovation go hand in hand. When AESSEAL – renowned for its commitment to environmental responsibility – sought to modernise its office climate systems, it turned to Airmaster for a solution that would match its high standards for efficiency, reliability and sustainability.
The result? A state-of-the-art, low-carbon hybrid HVAC system designed not only to reduce environmental impact, but to future-proof the workplace for changing climates and working patterns.
High Efficiency, Low Impact
The brief from AESSEAL was clear: reduce the carbon footprint of their office HVAC system while maintaining high performance and comfort for staff. Airmaster responded with the installation of a Mitsubishi Electric R32 Hybrid VRF system – a significant upgrade from traditional refrigerant systems thanks to its lower global warming potential (GWP) and hybrid use of refrigerant and water to deliver both heating and cooling simultaneously.
With a GWP of 675 – a considerable drop from the previous R410a-based system – the new setup not only cuts emissions, but supports AESSEAL’s wider decarbonisation goals.
Intelligent Infrastructure
As part of the office refurbishment, Airmaster carried out extensive ductwork modifications to optimise airflow. Fresh air is delivered to fan coil units mounted in the ceiling void, where it is pre-conditioned before being distributed evenly throughout the office. Secondary ductwork was connected and insulated to ensure balanced delivery via sleek linear grilles running the full length of the space.
The hybrid system required sophisticated integration – including a category 5 break tank, pressure monitoring, and distribution pipework – all connected to a central touch-screen controller. This intelligent system provides advanced diagnostics, zoning and scheduling, while seamlessly linking with AESSEAL’s building management system through BACnet protocol.
Partnership in Progress
Phase one of the installation was completed in August 2024, transforming the comfort and energy profile of the company’s modernised office floor. A second phase is already underway, expanding the system to additional areas of the Rotherham site from February 2025. Later this year, AESSEAL will go even further – removing legacy gas boilers in favour of more efficient, lower-carbon technologies inspired by the success of their warehouse heating systems.
Airmaster’s work with AESSEAL reflects a growing trend in South Yorkshire’s business community: a shift towards sustainable, intelligent infrastructure that supports both environmental goals and workplace wellbeing. As the region continues to lead in advanced manufacturing and green innovation, collaborations like this one are setting the benchmark for what a modern, climate-conscious workplace can look like.
For businesses looking to reduce their carbon footprint without compromising on performance, Airmaster is proving to be the partner of choice.
