EXAIR NEMA 4X (IP66) UL Cabinet Coolers

EXAIR NEMA 4X (IP66) UL cabinet coolers are dust- and oil-tight, splash-proof and suitable for indoor and outdoor use in hazardous locations, manufactured from stainless steel 303 or stainless steel 316. NEMA 4 UL control cabinet coolers are approved according to the UL (not ATEX) guideline for application to hazardous locations and meet the following classifications: Class I Div 1, Groups A, B, C and D; Class II Div 1, Groups E, F and G – and Class III. NEMA 4 classification is ensured by installing a low pressure check valve for all air outlets. Control cabinet coolers are particularly suitable for systems that require only occasional cooling. If the temperature rises in summer and the cabinet is no longer sufficiently cooled, control cabinet cooling can be activated. Even in environments where the ambient temperature is generally high or where the air contains a lot of dust or dirt, control cabinet coolers are often the only solution. Fans are then of little use and only blow dust or dirt into the control cabinet. Devices function with difficulty in high temperature and break down much faster. Dusty spaces require not only control cabinet cooling to keep the dirt at bay.
