Mansfield Pollard delivers hospital AHU solution

Mansfield Pollard has completed the design, manufacture and delivery of six fully electric air handling units (AHUs) for the new £80million Ambulatory Diagnostic Centre (ADC) at West Middlesex University Hospital.

Each AHU was designed and manufactured to meet the specific environmental and clinical requirements of its destination department, including imaging, oncology, dialysis and education spaces.

All systems are fully compliant with Health Technical Memorandum (HTM) 03-01 and deliver precise control over temperature, filtration, air quality and pressure across each critical zone. Airflow design and filtration configurations were tailored to protect immunocompromised patients and support clinical performance in highly sensitive treatment environments.

Each unit connects directly to the hospital’s building management system through a factory-fitted controls package, allowing real-time monitoring and automatic adjustments to maintain the right conditions across different departments.

To boost energy efficiency, the AHUs use advanced components such as EC fan arrays, DX heat pump coils, and counterflow heat exchangers that recover warmth from outgoing air. The units are built to high standards for air tightness and insulation, with critical components carefully positioned for long-term reliability in demanding healthcare settings.
 
Lou Ellis-Frankland, Chief Executive Officer of Mansfield Pollard, said: “This project demonstrates how healthcare ventilation can support real decarbonisation. By transitioning to fully electric systems, and tailoring each unit to specific clinical needs, we’ve helped future-proof the hospital’s infrastructure while supporting national Net Zero goals. Our team worked closely with delivery partners to ensure performance, safety and sustainability were delivered without compromise.”
 
The new centre will increase diagnostic capacity by 43%, supporting an additional 67,000 imaging procedures annually and doubling chemotherapy and dialysis capacity. The ADC is one of a number of NHS projects supported by Mansfield Pollard, whose decarbonisation-focused air handling systems are now in use across healthcare, retail and manufacturing estates nationwide.
