Medical Air Technology return to George Eliot Hospital for total turnkey project
After the success of an earlier project at the George Eliot Hospital NHS Trust in Nuneaton, Medical Air Technology (MAT) has completed another major theatre refurbishment and upgrade on the site, further improving flexibility and patient flow. Of the hospital’s nine operating theatres, four now have an MAT ECO- flow™ ultraclean ventilation (UCV) canopy, allowing a full range of procedures to be carried out, including orthopaedic surgery. The work was completed in just two months, including stripout and commissioning of the final system, and theatre shutdown time was kept to an absolute minimum. Close collaboration between hospital staff and the team from MAT ensured there was no impact on patient care while the upgrade was underway.
Theatres 3 and 4 already had MAT laminar flow canopies, which had been performing very successfully since they were installed. However, technology has advanced and their replacement with MAT’s ECO-flow™ canopies was a major part of the refurbishment. The innovative and advanced ECO-flow™ is engineered to significantly reduce energy usage and cost, without any reduction in the level of performance. The system uses up to 60% less power than other similar canopies, even in full ultraclean mode. Energy efficiency is achieved through innovative internal design and the introduction of infinitely variable-speed DC motors, while highly efficient centrifugal fans reduce the energy drain required for cooling. The introduction of LED cruciform lighting also improves energy efficiency. The new user-friendly canopies offer larger clean zones and are exceptionally quiet, enhancing the operating experience for clinical staff.
This total turnkey project also included a major stripout and replacement of ductwork, new air handling units, operating lights, BMS control panels, medical gas pendants, touchscreen surgeon’s or theatre control panels, PACS viewers, and IPS and UPS electrical systems. Both anaesthetic rooms were also upgraded to improve the patient journey through the theatres. New vinyl flooring, ceilings, hygienic wall cladding and LED general lighting throughout completed the upgrade of this fully HBN and HTM-compliant theatre suite.
MAT offers a wide breadth of services that mean is it able to respond flexibly and quickly to the specific needs of each client. With its own manufacturing facility and dedicated team of highly skilled engineers, the company manufactures and supplies bespoke equipment for demanding clinical arenas. Clients choosing the total turnkey solution, as the George Eliot Hospital NHS Trust did, gain from having a single point of contact to project manage the entire installation, resulting in benefits such as improved co-ordination, faster response, continuity of drawings, better communication between people and products, and streamlined logistics.
MAT also offers “equipment only” packages, delivered working closely with the main contractor. 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.
