Work environments do their utmost to account for staff comfort, equating a cool workforce with high productivity. Consequently, a facility typically provides ample ventilation and fans to keep the air at a comfortable temperature. But times change, and the number of workers increases. Expansion takes place. A well-balanced cooling system strains to cope but fails. Heat is radiating from friction-based tools, and electronic circuitry is failing due to the circulation of extreme heat. The addition of more fans reduces the calamitous effects of industrial heat, but the hot space needs an active solution to dramatically improve cooling. This is a typical circumstance for adding evaporative coolers as a dynamic means of bringing high temperatures down to a work-comfortable level.

Overviews of cooling technology quote evaporative models as profit winners, as appliances capable of cooling large spaces without applying exorbitant amounts of energy. Here’s a basic industry-based equation that demonstrates the efficiency of these coolers: Raw material goes in one end, is processed by tools and a labor force, and the fabricated output forms a product that sells to create a company profit, a solid entry in the positive earnings column. An evaporative cooler used on the industrial scale enters the middle part of this process, keeping the work ticking along without consuming tons of energy and killing the profit. The device employs the same principle as its residential brethren, the suction of hot air through a fan, the discharge of cool air to the floor of a factory, a greenhouse, or any area of notable size where heat is causing a problem. The laws of physics take care of the cooling action by adding the placement of a cooling medium in-between the powerful fan and the fast-moving air. This medium is a mechanical circulatory system full of water as delivered by the heart of the device, an electrical pump.

Created far tougher than comparable household models, industrial evaporative coolers house their parts in a stainless steel chassis that can be fixed in place as part of a permanent system, or the device can act as a standalone model, wheeled from one section of the facility to the next. A compartmentalized design is integral in the engineering design. Gasket seals close access panels, preventing water and air from mixing. The same principle of design separates the wet section, the space where the water tank and pump are located, from the dry compartment. Logically, all electrics are kept in the dry cabinet. But it’s the Green effects of the device that are promoted above the engineering aspects. The multi-speed fan consumes very little electricity, and the industrial design focuses on the quality of construction and sealing, reducing maintenance and any possibility of corrosion.

A corrugated evaporative module with a large surface area may be the secret to transferring the heat to the rapidly pumped water within the cooler, but it’s the application of a cooling theory older than the industrial age that stops the heat, increasing productivity without emptying the company wallet.
