Considering that Australia is the largest emitter of greenhouse gases per capita in the world, ensuring that a cold storage or refrigerated production facility is operating at its optimum efficiency means not only will a company reduce their carbon footprint but they can also save money due to a reduction in energy usage.
Envico Doors have recently undertaken a study into the benefit of the use of Envico Rapid Roller door as opposed to a standard PVC swing door within a refrigerated environment. Using data analysis equipment placed on identical entrances and environments Envico was able to collect comparable information including: exchange and moisture mass flow rates, heat ingress and importantly daily Kw usage rates. The results of the study showed that there was a 26% reduction in Kw usage when an Envico High Speed Door was installed, in this case that equated to a saving of around $5K per year in energy costs.
Enhanced sealing properties, positive pressure resistance and high operating speeds give the Envico range of high speed doors the ability to minimize the amount of cold air that escapes from a refrigerated facility whilst also reducing the ingress of warm air. The Envico range of high speed doors includes a variety of solutions for all door requirements including sizes up to 9 X 9 meters and a specialty freezer door which incorporates an insulated curtain rated to -25 deg.
Mark Brunton, director and designer of Envico “obviously it is in our best interest to have this information as a promotion tool for our range, but these figures show that there can be significant dollar savings for a company and also a reduction of waste in the form energy loss. This is particularly important in a warm climate like Australia where inside and outside temperatures of a facility can be very different”.
