Genesal Energy, part of Manchester Royal Infirmary’s refurbishment

Genesal Energy is proud to announce its involvement in the refurbishment of the Manchester Royal Infirmary (MRI) Emergency Department.

This ambitious project not only aims to improve the hospital’s facilities, but also reaffirms the commitment to providing a first-class healthcare service in a constantly evolving landscape of medicine. The renovation of this facility is designed to increase capacity and improve efficiency, adapting to the changing needs of today’s healthcare.

With nearly 5,200 square metres, 27 Boxes, six new ORs and 10 resuscitation rooms, the hospital will be consolidated as a regional centre of reference for the management of emergencies, trauma and various specialised surgeries.

One of the biggest challenges is to ensure that the Emergency Department and the ORs remain operational during the construction works. Temporary access routes and segregated work areas will be implemented, allowing the hospital to continue to provide vital services with minimal impact to users.

A crucial element of this project is the design and installation of a 1770 kVA soundproof generator set for hospitals. This system not only provides a reliable power solution, but also meets the stringent acoustic requirements of the hospital environment, achieving an average attenuation level of 75-78 dB(A) at 1 metre.

This project was installed by one of our UK Partners Ingram installations Ltd. Ingram installations is one of the UK’s leading Standby Generator Specialist installers that has been working with the UK’s NHS for over 50yrs. Genesal Energy, together with Manchester University NHS Foundation Trust (MFT) and Ingram installations Ltd., is committed to leaving a lasting legacy for staff, patients and the community the hospital serves.

Our Engineering Solution

To guarantee a minimum noise level was paramount, so a 40 feet HC container with double rock wool acoustic insulation (100 mm) and an acoustic membrane on walls and ceiling was designed. It is also fire resistant for 60 minutes (RF-60 Panel).

For further noise reduction, large air inlet and outlet baffles have been installed, as well as an external reinforcement silencer on the air outlet. The – 30 dB stainless steel exhaust silencer has been incorporated to prevent corrosion.

To ensure total soundproofing while the unit is switched off, motorised air inlet and outlet louvres are fitted, which close automatically. The power connection of the generator is made by means of a Modular Busbar System, which has required the design of an external Link Box that allows a flexible and safe connection.

This Link Box is powered directly from the genset power cabinet via internal wiring with six wires per phase of 240 mm², ensuring efficient power management. In addition, the genset is equipped with a 1,000 litre double-walled fuel tank feeding directly the engine via double-walled fuel pipes, with a vacuum leaks detection system. In the event of a fire, a mechanical safety shut-off valve is activated, shutting down the engine immediately.

To ensure efficient refuelling, the system includes a custom-designed redundant fuel transfer system with dual pumps and a ‘Flow Switch’ for automatic switching between pumps. This system can be connected to an external mother tank, ensuring a constant and reliable fuel supply.

Finally, the generator features a dual start system, which includes two electric starter motors and a double set of AGM batteries, ensuring operability in critical situations.

Features

• 40′ HC container with double rock wool insulation in walls and ceiling. Air inlet and outlet baffles. Interior and external air outlet silencers attached. All to meet the specific attenuation level of 75-78 dB (A) at 1 metre.
• 1,000 litres Double-walled (Steel-steel) fuel tank with leak detection (vacuum) at the rear of the container.
• Double-walled, leak-detection (vacuum) fuel pipes.
• Redundant fuel transfer system, with double pump (24Vdc & 230Vac). Both with manual shut-off valve and limit switch. In addition, a ‘Flow Switch’ for the automatic changeover from one to the other and a motorised valve (with spring return to closed position).
• Easily accessible from the outside control panel
• Power panel independent of the monoblock, and therefore isolated from vibrations, with adjustable LSI switch and busbar with top outlet.
