50 to 500 kW - Air Blast Dry Coolers - Water to Air
Description
Our standard AF range of Dry Coolers are air-cooled liquid heat exchangers manufactured from copper tubes with extended aluminium finned heat transfer surfaces. They are supplied as a complete fan, heat exchanger assembly with vertical air flow and do not include coolant pumping circuits. Our Dry Coolers can also be supplied with horizontal air flows, V bed configurations, stainless steel tubes and various fin finishes and materials.
The AF range of Dry Coolers have many advantages over mains water or open tower cooling and provide an ideal method of maintaining suitable working temperatures in many process applications. They can be used to remove heat from processes where the required coolant temperature is approximately 10°C – 20°C higher than ambient. Typical industrial applications for our Dry Coolers include heat removal from induction equipment, welding plant, vacuum chambers and Dynamo-meters. Other applications for our Dry Coolers include the indirect cooling of refrigeration and air conditioning circuits and supplementary free cooling.
