Yuasa chosen to help clear the way in underground ventilation system


GS Yuasa’s industry-leading industrial batteries have been installed as part of a smoke and fume ventilation system in the town of Poundbury in Dorset.

The batteries, installed in an underground car park, provide back-up power to a ventilation system. In the case of a fire occurring in the car park, or any of the vehicles parked within it, the ventilation system is designed to reduce both smoke density and temperature. It also increases ventilation allowing for the accelerated clearance of smoke once the fire has been extinguished.

One of the unique demands for this type of system is the need to meet the requirements of the ‘BS9999 Code of Practice for Fire Safety in the Design, Management and use of Buildings’. This includes the need to have two independent power supplies.

Mark Trolley, commercial director at UPS Power Services Ltd, said: “As this wasn’t possible in this location, this part of the standard is met by using an Uninterruptable Power Supply (UPS) for the secondary supply in case of a mains failure. This is not intended to assist in means of escape in case of a fire but to assist fire-fighting operations by providing smoke clearance.”

Commissioned, delivered and installed by UPS Power Services, the system uses 120 Yuasa SWL3300FR batteries to provide up to three hours back-up power. The SWL series is made in Britain, maintenance free and has a 10 to 12-year Eurobat classification. Designed for use in UPS and other high-rate discharge applications, the SWL series is available in both 6 and 12 Volt types and ranges from 24 to 120 Ampere hours (Ah).

Trolley added: “We chose Yuasa’s SWL series due to its technical superiority and unparalleled reliability. Their aftersales support is fantastic too, as is the ability to add a five-year warranty to the product, making them the perfect choice for the Poundbury project.”

Lee Allen, regional sales manager for GS Yuasa Battery Sales UK Ltd said: “Yuasa batteries are used in a wide variety of innovative applications across the world – their reputation for quality makes them the obvious choice for UPS systems where dependability is key. We were delighted to be chosen by UPS Power Services as the preferred battery supplier for their Poundbury project.”
