The cooler is a kind of heat exchange equipment, which is used to cool the fluid.Usually water or air is used as a coolant to remove heat. A recuperative cooler, spray cooler, jacket type cooler and cooler coil etc..Widely used in high power silicon rectifier and induction furnace and medium frequency furnace electric equipment as a pay of pure water, water, grease and oil cooling device for cooling protection.Water filter for backwashing type structure, also known as the industrial water filter, break up that move water filter and filtering electric water heater for in pipe diameter dn50-500mm power plants, chemical industry, printing and dyeing, papermaking and so a variety of industry for water supply pipeline, filter water greater than 2mm debris, the water filter has advantages as follows.

1: small size, easy to site layout and installation.
2: filter water inlet and outlet structure for the upper and lower split, not only to avoid pressure of a direct impact on the screen, but also changed the traditional filter because of debris from the sewage outfall, sewage required on several filtration room one by one to wash, tends to cause blocking phenomenon.
3: mesh material and structure to maximize water over flow area, effectively reduce the resistance of the screen, to ensure reliable operation card, plug, plug phenomenon does not occur, thereby greatly prolonging the service life of the filter screen.
4: filter using 2-8mm stainless steel plate as a whole stamping process, the net core can withstand 150 kPa of the differential pressure, but not deformation, no damage. With long working life, corrosion resistance, non - rust, smooth surface, non - scaling characteristics.
5: electric device speed is slow, running smoothly, can be positive and reverse washing, cleaning effect is strong, sewage water consumption is low.
