1.Hi-efficient heating coil Heating coil is made from ellipse copper tubes that welded after being tested.To be sure no leakage, Pressure test at 1.6 Mpa for one set coil should be had in the water. Ellipse tube may raise the acreage of heating coil.Intersect tube, reasonable distance between tubes and water film on the tube wall promote evaporating and cooling efficient. Flow direction of air outside coil and cooled water is opposite, ellipse tube and intersect tube make the beat-ing coil excellent heating effcient and lower air resistant.
2.Hi-efficient spray circulating system ABS special nozzle has the features of much spray water, well-distributed water and on blocked up.Rea-sonable layout of tube, height of spray and layout of nozzle can become will-distributed water film outer wall of heating coil and preventing from reverse flow. Spray circulating system is equipped with scour-resistant device, which reduce corrosion and promote the efficient of heat exchange. Circulating pump is mounted outdoor will reduce power consumption and maintenance.
