Countess of Chester Hospital
Medical Air Technology (MAT) has completed another successful theatre refurbishment, this time at the Countess of Chester Hospital. The large 600-bed district general hospital, operated by the Countess of Chester NHS Foundation Trust, serves patients from Western Cheshire, Ellesmere Port, Neston and North Wales. In order to meet the growing number of referrals it receives for orthopaedic surgery, the hospital brought MAT in to completely refit and upgrade Theatre 9 and bring it up to the standard required for orthopaedic procedures with the installation of an ECOflow™ ultraclean ventilation (UCV) canopy.
MAT was awarded the contract for the work after tendering a winning bid that demonstrated it had the expertise and capacity to deliver the project within the required time and budget. MAT has carried out previous theatre upgrades at the site and has developed an excellent working relationship with the estates department and project teams, with all parties working closely together to ensure the best outcome.
Work on Theatre 9 was carried out between October and December 2018. It included a full stripout of all existing services and replacement of the air handling unit (AHU), building management system (BMS), ductwork, domestic water services, medical gas system and fire alarm modification. The theatre features new general lighting, a theatre control panel and an IPS/UPS system. At its heart lies the MAT ECO-flow™ UCV canopy, which dilutes air so it contains not more than 10 CFU/m3, the level required for ultraclean air in HTM 03-01. Creating a ‘clean zone’ around the patient that is effectively free of bacteria-carrying airborne particles while the operation is in progress reduces contaminants at the wound site and dramatically reduces the risk of post-operative infection, meaning less requirement for antibiotics, less chance of costly remedial surgery and less ensuing pressure on already busy operating theatres. MAT also carried out commissioning of the new theatre prior to its opening.
MAT offers a wide range of services so is able to respond flexibly and quickly to the specific needs of each client, providing all the benefits that come from working with a specialist contractor. With its own in-house UK manufacturing facility and dedicated team of highly skilled engineers, MAT manufactures and supplies bespoke equipment for demanding clinical arenas. Clients can choose from several options, ranging from UCV canopy only right through to a total turnkey package, ensuring they get exactly the solution they need. In addition, MAT FM can provide a range of competitively priced and highly effective service and maintenance packages for all core products and turnkey solutions offered by MAT or other suppliers, ensuring that equipment is maintained, serviced and validated correctly for optimum performance.

After completing several previous cleanroom and containment laboratory projects at Imperial College London, MAT was proud and excited to once again have the opportunity to work in partnership with such a prestigious institution to deliver the new research environments.
After initial designs were developed and approved, building work began in summer 2020 and the new cleanrooms were handed over in June 2021, the entire project having taken just 11 months.
Imperial College London is a global top ten university with a world class reputation. Its alumni include 14 Nobel Prize winners, including Sir Alexander Fleming.
To enable the highest level of research, the university offers the best
possible facilities. One of its flagship buildings is the £90m Sir Michael
Uren Hub, located at the White City campus. Designed as a
collaborative facility, the 13-storey Hub provides space for Imperial’s
world-leading researchers, engineers, scientists and clinicians to work
alongside one another to investigate some of the twenty first century’s
most urgent biomedical and healthcare problems.
FEATURES CONTAINED WITHIN THE CLEANROOMS:
The new cleanrooms MAT was commissioned to design and build both had to be ISO Class 6 standard to safely accommodate the semiconductor research that would be carried out in them. Class 6, as defined in ISO 14644-1:2015 Cleanrooms and Controlled Environments, refers to the cleanliness levels that must be met within the cleanroom.
In addition to having a high air change rate, an ISO 6 environment must be accessed through airlocks to preserve pressurisation differentials and prevent the migration of particles from outside into the cleanroom space, increasing one class at a time. So, users should pass through an ISO 8 environment, then an ISO 7 environment, before entering the ISO 6 cleanroom.
MAT acted as the designer and main contractor on the cleanroom project, working closely with the university to ensure minimum disruption to the other activities being carried out in the Sir Michael Uren Hub.
The team developed a design built around the complex research equipment and specialist tools that would be housed in the new cleanrooms. Work included final services connections and extensive bottled and house gases installation to several hazardous gases and associated gas detection systems.
HVAC design is complex and requires a highly skilled delivery team.
MAT is an expert in the provision of specialist HVAC systems. The HVAC system is at the heart of cleanroom design. Cleanroom HVACs differ from standard systems in that they have an increased air supply, different airflow patterns, use of high efficiency particulate air (HEPA) filters, and room pressurisation, and clean to dirty room air cascades.
In order to meet the required air cleanliness, the air must pass through HEPA filters. The lower the ISO class, the more often the air must pass through the HEPA filter. This ‘air changes per hour’ rate (ACH) and the room volume are used to calculate the HVAC’s required airflow. A conventional HVAC system usually makes two to four air changes per hour, whereas in a cleanroom it can range anywhere from 10 to 250 or even more.
The ISO Class 6 cleanrooms at Imperial College London require air change rates from 50 to 70 per hour.
MAT designs, manufactures and installs bespoke critical ventilation systems and turnkey project solutions for new build and refurbishment projects. As a specialist contractor with many years’ experience, we are passionately committed to improving patient protection and end-user safety in demanding clinical, research and drug production arenas.
We have extensive experience of working in live environments and understand the challenges around delivering a project within an operational scenario.
In addition, MAT FM provides a range of competitively priced and highly effective service and maintenance packages for all core products and turnkey solutions offered by MAT or other suppliers, ensuring that equipment is maintained, serviced and validated correctly for optimum performance.
