Transparent roller shutter door reduces energy loss

A high speed industrial roller shutter door has been installed at Brita Walter Filter’s manufacturing and logistics centre in Bicester.

Produced by sara LBS the Sprint 392 has been shown to reduce energy losses, keep rodents out and improve safety through and increased natural light level.

Its manufacturing site in Bicester, Oxon supplies the company’s global distribution network, so has a constant flow of goods inward and outward throughout its five day working week. At goods inwards there are four loading bays fitted with dock levellers, plus one level travel route into the building. Warehouse Manager, Bryan Edwards, says that efficiency and reliability of the loading bays are essential to smooth operations throughout the whole plant.

“The level bay has an outer roller door plus a PVC inner door,” he says. “Originally, the latter was transparent but, after many years of operation, it was turning opaque. This meant the loading bay lights were switching on automatically more and more often, and I was also beginning to worry that door’s reliability would become an issue. So I started to look for replacement options.”

Brita required a high quality solution that was suitable for temperature control, to improve energy efficiency, and ingress protection, with a particular emphasis on rodent control. sara LBS produced the roller doors for the site that required multiple cycles a day performed reliably for years.

Bryan Edwards and colleagues were able to visit a number of Sprint 392 installations in the local area that demonstrated the quality of the product and the seal it provides when closed.

sara LBS has a range of Sprint products to which they state offers the fastest operating speeds on the market, making it suitable for most industrial applications. Special features of the Sprint range include the sara LBS non-contact travelling safety beam, which is fitted as standard and provides unparalleled safety for personnel and equipment.

The drive on the Sprint includes sara LBS’s patented MCC Vector Frequency control system, which facilitates the fast operating speeds and reliability by optimising the acceleration and deceleration rates to reduce wear and tear. Brita was pleased with the installations they visited and tested, and specified the Sprint 392 with a transparent curtain as their chosen product.

At 4.5m high and 3.5m wide, Brita’s actual door opening is quite large, and the acceleration/deceleration profile was worked out to give a top speed of 3m/s to ensure rapid operation. The seal was tested to ensure rodent proofing, particularly at the bottom profile. On average it opens and closes 20 times a day, five days a week and is expected to have a working life of 10-20 years.

Bryan added the installation for the product went smoothly and only took three days as there were no major issues faced. Long term there has been energy savings and the roller shutter door has been very reliable, yet the immediate affect was the clarity of the PVC curtain. “It lets in so much more light that the overhead lights were rarely coming on and the improved visibility ensured safety and a pleasant working environment.”
