When hot weather causes the electronics inside a control cabinet to fail, the operator might choose to simply open the panel door and aim a fan at the circuit boards. The fan ends up blowing a lot of hot, humid, dirty air at the electronics and the cooling effect is minimal. If the machinery starts functioning again, the likelihood of repeated failure is great since the environment is still hot and threatens permanent damage to the circuit boards. Worse yet, that open panel door is a safety violation that presents a shock hazard to personnel.
EXAIR has a complete line of Cabinet Coolers that are suitable for PLCs, line control cabinets, CCTV cameras, modular controls, etc. They mount in minutes through an ordinary electrical knockout and have no moving parts to wear out, eliminating maintenance concerns and making them virtually impervious to hostile environments. Wastewater treatment, chemical processing, food processing, paper manufacturing, steel mills and power generation are just a few of the facilities that are suitable for the technology.
NEMA 12 (IP54) Cabinet Coolers are dust-tight and oil-tight. They are suited to general industrial environments where no liquids or corrosives are present.
NEMA 4 (IP66) Cabinet Coolers are dust-tight, oil-tight, splash-resistant and indoor/outdoor capable. They incorporate a low-pressure valve for the air exhaust, which closes and seals when not operating to maintain enclosure integrity.
NEMA 4X (IP66) Cabinet Coolers offer the same protection as NEMA 4 systems. They are available in 303SS and 316SS for food and chemical processing, pharmaceutical, foundries, heat treating and other corrosive environments.
High Temperature Cabinet Coolers for NEMA 12, 4 and 4X applications are suitable for ambient temperatures up to 93°C. They are suitable for mounting near ovens, furnaces and other hot locations.
Thermostat control to minimise compressed air use is available for all models. All EXAIR Cabinet Coolers are UL Listed and CE Compliant.
