A heat exchanger is a heat-transfer device that is used for the transfer of thermal energy b/w two or more fluids (gas or liquid) available at different temperatures. The primary elements of a PHE include the heat transfer plates, gaskets, the supporting end frames (a fixed and a movable cover plate or frame) that house inlet & outlet fluid port nozzle, carrying and guiding bars, the supporting column, and end-frame tightening bolts.
Air-oil coolers as the name states are another type of heat exchanger (read about plate type and shell and tube type in our previous blog) that make use of oil for cooling purposes. Engine oil coolers/ heat exchangers are small radiators placed in front of engines, in most cases automobile with a fan present.
Heat exchangers operate by intermittently passing hot and cold liquid contents across opposite sides of a conductive thermal metal. The hot liquid runs through the metal into the cold liquid without making any physical contact. This process is facilitated by fluid velocity, turbulence and temperature differentials and brings about the heat transfer rate depending on the heat exchanger structure.
Traction transformers are critical components in a locomotive and Varalka Transformer Oil Coolers are providing satisfactory service for traction transformers for metro and local trains all over the country. Flow of electric current through the winding and due to core losses, heat is produced in the windings and core of the transformer.
Air oil cooling is the use of engine oil as a coolant. The most typical applications involve using these means as a way of removing surplus heat from an engine, usually a combustion engine. Air oil coolers/heat exchangers operate by the engine in relation transferring heat to the oil when is then transferred into the heat exchanger.
What are ammonia refrigeration systems (ARS)? Ammonia refrigeration systems are one of the older types of refrigeration means used up till now. This application ever since discovery in France in the 1980s has been used in just about any company that deals in perishable goods such as foods and drinks to keep their products within required temperatures.

There is the general perception that the effectiveness of any plate heat exchanger (PHE) is only dependent on qualities such as the build makeup, the materials used in development, maintenance routines and also the environment in which the heat exchanger operates in and in what conditions it operates on.
Just installed a heat exchanger but not sure how to maintain it properly? Worry not! After reading this, you will have a fair idea about how to service your heat exchanger. Heat exchangers, just like any other appliance, need to be maintained and serviced on a regular basis to prevent long-term damage. Why? Not only does regular maintenance ensure operational efficiency, but also reduces downtime and improves the life of the equipment.
