Off-line Cooler BNK ATEX-3GD

Drives and hydraulic aggregates are also used in explosive areas in machine construction or raw material production. In hydraulic systems oil transfers power and motion, in drives, it’s a vital lubricant. Both as a power transfer medium and lubricant oil is heated by friction losses during operation. Oil/ air coolers stabilize the temperature and are indispensable for systems and drives for consistent power. The temperature further affects the aging behavior and the life of oils. BNK ATEX 3GD series coolers are suitable for use in zones 2 (gas) and 22 (dust) and temperature class 3. In addition to adequately protected drive motors, they are designed for easy maintenance and have a noise-optimized fan. To minimize the negative fluctuating oil flow has on the cooler design with varying ambient air temperatures, the BNK ATEX series features a built-in generator pump to circulate the oil.
