● large internal space, convenient maintenance;
● fully closed circulation, to prevent blockage caused by sundries;
● the heat exchanger adopts the building block superposition mode, which can be installed and disassembled layer by layer;
● no need for water pool, small land occupation and convenient relocation;
● automatic digital display temperature control, energy saving and environmental protection;
● simple operation and low maintenance cost.
Product description
● WBH series closed cooling tower is improved on the absorption of good heat exchange technology, and a kind of efficient heat exchange equipment is developed.
Product performance
The WBH product uses the technology of the combination of coil and PVC filler of the air-water mixed flow type secondary heat exchange to realize the efficient heat exchange. Because the air and spray water flow through the coil in the same direction, the spray water can cover the surface of the coil to a large extent, so that the surface of the coil is completely wet. Compared with the air-water reverse structure, the formation of the dry point and the ditch of the coil wall is greatly reduced.
Fan
● the ventilation system adopts aluminum alloy axial flow fan of cooling tower, with forward inclined blade structure design, streamlined inlet air duct, small wind resistance, large air volume, low noise, good performance and high efficiency. No belt drive structure, reduce the transmission parts, and adopt the fully enclosed self cooling low noise cooling tower motor, with small size, light weight, good starting performance, reliable operation, durable and other advantages!
Low failure rate
High quality bearings are used for fans and water pumps, and there are no other wearing parts. The fan adopts direct connection structure. No rotation loss caused by pulley structure, low noise and low failure rate.
PVC filler heat exchange layer
The designed PVC honeycomb cross flow and short-cut cross air inlet structure enable the air to carry the heat in the water. The packing flow passage enables the water flow to form a large area of flowing water film on the surface of the packing, prolongs the cooling time of the water in the packing, and improves the cooling effect of the water. The utility model has the advantages of small wind resistance coefficient, anti-aging and no deformation.
circulatory system
The circulating water pump adopts closed cooling tower pipe pump, with stable performance, convenient maintenance, low voice, beautiful appearance, installation dimension in accordance with ISO2858 standard, motor protection grade IP55, insulation grade F, and the circulating water tank adopts SUS304 stainless steel plate, stamping forming, beautiful appearance and strong pressure resistance. The material of the connecting pipeline between the circulating pump unit and the water tank can be customized according to the customer's requirements. The base frame is based on the quality of the pump set to match the corresponding specifications of channel steel, which is simple to operate, stable and firm, and convenient to transport.
cooler
The design of cooling coil can make the operation power higher, the design of double row pipe can make the arrangement of pipes compact, and reduce the flow resistance of air at the same time. The coil is inclined to extend the flow direction of circulating medium. At the same time, air inlet valve and drain valve are set at the inlet and outlet of circulating medium. When the equipment is shut down, open the air inlet and drain valve, and the circulating medium will be discharged automatically. It has successfully solved the common problem of cold cracking of coil pipes in winter that puzzled the same manufacturers. The design pressure of cooling coil is 1.97mpa. After welding and assembly, the coil is tested in water for air tightness of 2.5MPa to ensure no leakage.
