1, the unique cold room independent system design, internal unit layout more reasonable. Will be vulnerable to the effects of high temperatures damage the electrical components and oil separation and filtration modules, placed in a cold room to improve the life of the unit. 2, professional air duct design makes the intake air temperature and the internal temperature of the compressor is kept relatively low, significantly improving the overall compression efficiency and stability. - A compressor inlet to provide separate intake passage, using cold air intake, improve the stability and efficiency. - To provide a separate cooler intake, greatly improving the cooling efficiency. - For the motors and electrical components to provide cooling air intake alone, to ensure reliability. - The top of the exhaust, user-friendly installation hot exhaust system with heat recovery.
