No more nightmare ‘night-door’ thanks to SMI’s Green Door

No more nightmare ‘night-door’ thanks to SMI’s Green Door

A unique innovation from the creators of world-leading Tempro thermal insulation is beginning to make its money-saving mark at Britain’s top supermarkets. It’s called the Green-Door . . . but it’s actually blue!

It is a more lightweight and user-friendly replacement for the unwieldy ‘night door’, with the potential to save a considerable amount of energy and physical effort for users of chiller units, and freezers.

Green-Door has been created by Seymour Manufacturing International (SMI), the company behind market-leading temperature control innovations such as Cold Stop curtains, and the vehicle energy-saving Back-Stop range.

After several years of painstaking research and development, and rigorous testing, Green-Door is now in production, and being trialled by top UK food retailers.

Green-Door uses the same acclaimed material as SMI’s ground-breaking temperature controlled curtains, cold room doors, flexible temperature-controlled zones, pallet covers, roll cage covers, bags and boxes.

All of the products use Tempro, which remains unchallenged as the world’s thinnest and most thermally-efficient material of its kind.

It is a popular choice in the food sector, and is now also being supplied to the health, logistics, military and pharmaceutical industries.

SMI chairman Brian Seymour explained: “Cheap flip-flap doors have been used in chillers for several years, despite having relatively short lifespans, high maintenance costs and breakage.

“We researched the real needs of the food industry and targeted economic performance, being user friendly, and longevity.

“With Green-Door, the aim was to create a quality door that would require little maintenance, was easy to use and saved significant amounts of energy, and carbon.”

When the product was 90 per cent completed, SMI began low-key trials to test the product’s performance under realistic and gruelling conditions.

Mr Seymour added: “Green-Door makes the much-hated supermarket night-door redundant in chillers and freezers, saving capital, maintenance costs, nuisance value and labour. The advantages and savings are enormous.”

The first pair of Green-Doors for chilled applications, replacing the night door, were installed at a busy Taunton supermarket in September 2009, and many more have since been successfully trialled at other retail sites.

Maintenance has been low, they have proved easy to use, and the loss of a night door has been described by the companies as ‘a gift’ to both management and staff alike.

“The Green-Door, supplied with its own frame and with integral Tempro thermal protection and built-in shock-resisting buffers, is a perfect answer to several major questions, and is bound to create keen interest,” said Mr Seymour.

“It is easy to use, it saves expensive energy and carbon, it reduces maintenance costs and the need to fit the hated time wasting, labour intensive, costly night-door.

“In fact, when return on investment is considered, the Green-Door could pay for itself on day one, depending upon what size and cost you pay for a night-door. The saving on maintenance and labour can just be treated as a bonus.”

SMI was founded in the 1980’s and has a blue-chip list of clients around the world.

Mr Seymour said: “We strongly recommend that no single cold room door is fitted unless it is at least 230mm larger than the goods entering the cold room, or 460mm for a double door.”
