Such Heat Exchangers are made up of stainless steel plates with gasket arrangements wherein the oil flows in one direction & water in other direction. They are compact in design & efficient.

Such types of heat exchanger are also called forced draft oil cooler. This is because the cooling in done by external fan. Here the oil is passed thru radiator & behind the radiator there will be fan which blows over the radiator thus cooling the oil. Radiators are made up of cooper tube with aluminum fins. Aluminum fins are bounded to the copper by expanding the cooper tube by high pressure water. These are manufactured by using special braze welding.  We manufacture mini range & higher range air blast type of heat exchanger depending upon the capacity & application. We have designed & developed certain models considering the hydraulic system which are normally used in the industries. We also supply custom built design as per the customer's requirements. These types of heat exchangers are normally supplied with AC power supply. We also supply with DC power supply and with shaft driven pulley.  Main advantages of these cooler are   No water is required for cooling. So can be used in remote places. Maintenance is less. Space required is less. can be moved from one place to other place. Such air blast type heat exchangers are mainly used in cooling of hydraulic oil in drain line of hydraulic system.
