Running smoothly
The unit's primary filter adopts plate type, and the filter material adopts nylon concave-convex net, which can be washed repeatedly. The medium-efficiency filter device is a bag-type non-woven fabric filter device.
The heat exchange system adopts high-quality copper tube with hydrophilic aluminum foil and is processed by a fully mechanical tube expansion process to ensure that there is no gap between the pipe and foil. All heat exchangers have undergone a 2.5MPa tightness test to ensure no leakage.
The air supply system adopts low-noise double-inlet centrifugal fan, which has undergone strict dynamic and static balance tests to ensure stable operation and low noise. Fan bearings are all internationally renowned brand products.
Excellent performance
The unit adopts non-cold bridge aluminum alloy structure with special cast aluminum fittings for insertion, high strength, light weight, corrosion resistance, high accuracy and long service life.
The shell of the unit adopts double-sided color steel plate, filled with high-density polyurethane foam insulation material, which has better thermal insulation performance than glass fiber material and higher strength. Its good thermal insulation performance prevents condensation in the unit under any climatic conditions. The overhaul surface of the unit adopts the locking technology with self-tightening function, which has high air tightness, low air leakage rate and easy disassembly and assembly.
This series of units has the characteristics of superior refrigeration performance, compact structure, light weight, good rigidity and corrosion resistance.
