Air conditioners for enclosure cooling

Closed-loop cooling systems are recommended for harsh environments, or when there are washdown requirements, heavy dust and debris, or airborne chemicals present.

Because heat inside an enclosure can decrease life expectancy in controlling units such as PLCs, HMI, and AC drives, AutomationDirect has added NEMA-rated Stratus air conditioners for enclosures to its line of enclosure products.

Excessive heat can cause nuisance faults from electrical and electronic components, circuit breakers and fuses. These closed-loop cooling systems are recommended for harsh environments, or when there are washdown requirements, heavy dust and debris, or airborne chemicals present.

Available in 120 V and 230 V units, the NEMA 12, 4 and 4X-frame Stratus 1,000 to 8,000 BTU/H air conditioners feature free-standing rigid chassis for easy installation and maintenance. NEMA 12 and 4 models are constructed of 16-gauge cold rolled steel; NEMA 4X units are made of 16-gauge 304 stainless steel. All units contain an active condensate management system and protective-coated condenser coils.

Designed to fit enclosures as shallow as 12 in., each unit features a digital LED temperature controller with visible alarm and is pre-wired for external alarm monitoring. The highly energy-efficient compressors are charged with CFC-free refrigerant and equipped with anti short-cycle protection. Replacement filters are also available for each of the three frame sizes.
