Air Curtains Provide Energy Saving Solutions



When you process and ship more than 1 billion packages a year through more than 150 fulfillment and sorting centers, those vast working spaces need to be consistently clean and comfortable despite dozens of wide openings for people and equipment to pass through 24/7.One Amazon center is so large it's the size of 28 football fields. These facilities are known to have internal temps reach over 90°F, which is a common challenge for large industrial spaces. In fact while large spaces with colossal doors and high ceilings would seemingly move air in and out rather well, HVAC experts affirm that they are instead known for their inherent air management challenges. And, while goods move in and out quickly, employees are long-term guests who have to deal with the air quality and temperature constraints for hours each day, year after year. Industrial facility managers need consistent, durable solutions that are customized for their unique climate and constraints.

The Solution

Amazon's industrial facility managers called in the titan of tough when it became clear that air management, climate control, employee safety and energy savings solutions could be realized with the right solution.Across the U.S., the Mars air curtain now stands guard at Amazon fulfillment and sorting facilities and manages their many large dock doors. They now safeguard against air transfer and pollutant infiltration, while keeping passages free and clear from obstructions that lead to accidents. Interior spaces can be climatically segregated to keep forklifts and engine-led equipment (and their exhaust) separated from other staff. Staff and customer entrances, known to be a source of dust, unconditioned air, and flying pests, are also under the protection of the Mars air management solution. Now entrances of every type rest secure, and Amazon facility managers can turn their focus back to their mission of ensuring speedy and accurate fulfillment of the thousands of boxes that pass through their doors.


When You're One of the Largest Shippers... You Use the Best Air Curtain


Cavernous manufacturing centers grapple with complexities — numerous staff, high traffic, inconsistent climate control, and ongoing pressure to create productive working environments to hit output goals month after month.In the Campbell Soup Company’s sprawling, 2.4 million-sq.-ft. facility, an array of exterior doors continually introduce outside air into the workspace. Facility managers were using propeller-based fans in an inefficient attempt to block the unwanted airflow responsible for drafts and shrinking productivity. The fans were doubly ineffective because they used excessive horsepower to produce a wide flow of unfocused air. The Mars Air Systems air curtain solution was able to produce a precision air barrier with a concentrated blast of air that used only 3 HP versus the old system's 15 HP. Better still, the Mars solution completely eliminated the view obstruction of the fans while consuming the energy equivalent of one standard metal parking light with a 1500-watt metal halide bulb operating for one hour.


When you bring in the world's top entertainment venue designers to build an iconic sports facility valued at $1.1B, filling the 1.75M sq ft structure with premium equipment that performs with the latest technology is the name of the game.U.S. Bank Stadium – home to the Minnesota Vikings football franchise – is big, bold, and best-in-breed. With entry doors that serve as the gateway for tens of thousands daily, they needed the most technologically-advanced way to thwart flying pests and keep climatized air inside and harsh winds outside. Now with 25 sizable Mars air curtains, fans experience a halo of heated air during Minnesota winters and an invisible protective barrier from dust and pests year–round. Down below, the dock doors that service a the facility's over 430 food points of sale, have their own protection with a cluster of Mars industrial air curtains, designed for environments that need heavy-duty brawn.


P&G's Cairo plant, the third largest diaper plant in the world, responsible for exporting 60 percent of its production to Europe, Asia and the Mid- East, often leads as one of Egypt’s top American business success stories.Set in an area known for legendary dust storms that transfer accumulated debris from the far reaches of the Saharan Desert, air quality measurements routinely record dangerously high levels of suspended particulate matter. Mars Air Systems to the rescue. With the installation of over 100 Mars air curtain units in a plant hosting over 1200 workers, the result was an effective embargo on bad air and dust from blowing in at doorways and entryways. By deploying the Mars comprehensive facility-wide approach to controlling both loading dock entries and doorways with a directed stream of air, facility managers were assured that unpredictable climatic conditions would surrender to the power of the Mars air curtain and their invisible shield of protection.


In their 62,000 sq. ft. facility, Empire Packaging and Displays produces $50M annually in corrugated boxes and power wing displays, many of which give food producers the means to package and ship products in hygienic envelopes. The Empire team realized that “plastic strips were the number one hazard in the factory – even more than the equipment we used,” said co-owner Hal Mottet, “because they were constantly dirty, had turned cloudy after a month of use, and were often pushed aside by staff who found them cumbersome and intrusive to their work.” The Empire team discovered that for a few dollars in electricity per month they could achieve a safe and effective barrier to keep dust, debris, and flying insects out of the plant, with the bonus of a more productive climatic conditions for workers. With the installation of three Mars air curtains over their 14-foot dock doors, “The plant is definitely more comfortable and visibility around the dock doors is at all-time highs which eliminates our worries about worker safety.
