    Air Doors Protect Against Food Borne Illness

    Brands Mars


    While a Health Department code may prescribe the barrier of air curtains to create cleaner pest-free food prep areas, the real mandate comes from patrons who insist on a fly-free guest experience with well managed temperatures that eliminate hot or cold air pockets. Creating a pest-free space with evenly distributed conditioned air does more than give guests the impression of clean, it’s actually a building block to designing a truly hygienic venue. New research is clear – food poisoning is directly linked to flies who carry pathogenic organisms that cause E. coli, salmonella and shingles and introduce other bacteria species. Leading chains recognize the risk and won’t leave their reputation up in the air when a bad experience can go viral as easily as a favorable review.


    Working hand in hand with the sanitation protocols you already have in place, Mars Air Systems’ air curtains above entry doors, pass through windows and back receiving doors becomes a silent take-charge partner that seizes control of keeping the uninvited “guests” out. And, we’ve been doing that for over 50 years for iconic hospitality brands such as Panda Express, In-N-Out Burger, Taco Bell, Subway, Olive Garden and growing up-and-comers like Smashburger and Five Guys Burgers. Whether it’s the need for a recessed unit that blends seamlessly in a well-defined décor vision, or defense against brutal weather conditions -- both hot and cold -- or the need for food storage areas to be vigorously defended from encroachments that threaten food quality and safety, Mars products have been the solution of choice for the most demanding operators world-wide. When creating true hospitality is on the menu and tireless 24/7 operations need to be the norm, Mars is the name that delivers.

    Mena House Hotel Cairo


    To make sure frozen food keeps its sensory and nutritional quality, as well as maintain food safety standards, temperature requirements have been set for every stage of the cold storage chain. No less a consideration is the hit to food storage life when products are exposed to temperature fluctuations. In challenging environments, the mere act of moving food from a transport truck to a freezer can raise the temperature of the food significantly and tax a cooling system as it struggles to return to the thermostat set point. The Mena House Hotel in heat-steeped Cairo, Egypt has welcomed dignitaries such as Winston Churchill, Queen Mary and Richard Nixon as well as average summer temperatures of 94°F to 104°F. With a bank of 20 foot by 20 foot freezers that needed repeated stocking to feed hotel guests, a solution of significance was on demand to unburden the freezer compressors, protect the food from heating up and give some relief to rising energy costs. Using a series of 42-inch custom-engineered models, the Mars Air Systems engineering team was able to create a wall of cold air sufficient enough to consistently halt the incursion of heat and dust. The air curtains eliminated temperature fluctuations, cut out the stress on the equipment trying to re-cool and helped reduce burgeoning energy costs.



    Campbell Soup Company, one of the largest food companies in the world, operates a sprawling, 2.4 million-sq.-ft. facility on a 949-acre parcel, which includes operating a cooler/freezer storage unit 24 hours/day alongside a 8’x16’ heavily trafficked forklift entrance with a fast-acting vertical-lift door. The hot, humid warehouse conditions collide with the cold, dry-storage area air which produces condensation and pools of water at the base of the freezer -- both inside and out. Water also flowed from the freezer opening directly into the walkways that hosted both foot and forklift traffic. The Mars Air Systems Engineering team isolated the precise area that needed an air burst then installed a bundle of door-activated air curtains and air diffusers right at the forklift entrance. The air curtain’s forced-air action stabilized cold area temperatures by creating an air seal which effectively evaporated most surface condensation and eliminated pools of water in the walkway.

    McDonald House Charities


    Sometimes the challenge is less a problem and more an opportunity to repeat what already works well. When Camp Ronald McDonald for Good Times in Southern California unveils a new dining hall in 2015 that will significantly enhance the camp experience for youth struggling with cancer and their families, two donated Mars Air Systems air curtains will stand guard over their foodservice delivery doors. For the staff, finding a solution meant having to look no further than skyward in the existing dining hall because a circa-1989 Mars air curtain is still hard at work in the retiring dining center. The 26-year old unit continues to create the wall of air needed to dispel dirt, dust and insects and repel exterior air. Happy to be able to keep the still-operating air curtain in place as the outmoded facility transitions to a culinary teaching center, the staff reached out to Mars for two additional workhorses. The Mars contribution joins with built-environment leaders such as HunterDouglas and Dupont™ Corian® to breathe life into the new 14,000 square foot complex so guests can recreate the family dining table while at camp.



    When you’re as successful as Westmoreland County Food Bank because you serve 7,200 families a month and operate a 40,000 sq.ft. facility that processes 8.6 million pounds of food a year, your food storage equipment needs to work flawlessly. For Westmoreland, facility limitations forced the freezer and evaporator to sit side-by-side which led to a healthy dose of humidity leading to ice and frost on the floor outside the freezer doorway – a safety hazard for both forklifts and workers on foot. When it’s too important or costly to be anything other than right, Mars Air Systems is the team you want on your side. Mars has been repeatedly the source for answers when large industrial and foodservice operators need no-fail solutions to vexing humidity, unwanted conden-sation or accident-provoking pools of water. Deploying air baffles to ride shotgun along side the series of air curtains gave the Westmoreland workers the means to ward off the flowing water that had been a source of slippage, falls and worker injury.
