We are manufacturing of the heat transfer equipment as per the TEMA (Tubular Exchanger Manufacturers Association) ASTM Section (VIII) (unfired pressure vessels) BS, DIN Standards. And follows IS 2825, IS 6088, IS 4503, codes. Our devices efficiently transfer heat from one fluid to another & are in wide use in engineering processes. We have the facility of various software from development of flow chart, P & I diagrams piping layout to preparation of fabrication drawing through CAD. It is supported by a library consisting of ASME, BS, ADMERKBLATTER, ANSI, IBR, TEMA, LLyod rules, Indian register of shipping rules, Regulation and standards. Our plant has modern plate processing, machining, welding, heat treatment, NDE and handling equipments.

We are using tubes of SS 304, 316, 304L, 316L, copper, brass etc for fixed or floating heads and removable or fixed tube bundle, in single or multi pass. In all plate materials are SS, CS, Aluminium etc. For high temperature and pressure with self latest computerized thermal as well as mechanical design. We provide well conceived optimum designs to suit every application of heat exchanger and recovery for captive consumption and OE application. Heat exchangers are having two divisions one is shell heat exchangers where there are two fluid Medias are used for exchanging heat in tube and shell side. For this purpose seamless/ERW pipes are used for shell and rolled shells are also used. For tubes seamless, copper, brass, cupronickel, stainless steel is used. The end of tube is properly expanded with tube expanded up to a pressure level of 1000 PSI pressure.

Fixed tube heat exchangers are the ones that are very much used in process chemical industries and refinery services, as there is absolutely no chance for intermixing of fluids. This type of heat exchanger is employed where even slightest intermixing of fluids can not be tolerated. The special features of Removable bundle type heat exchanger is that the tube bundle can be withdrawn from the shell which facilities cleaning of the outer surface of the tubes and inner surface of the shell. The sealing between the shell and tube side fluids achieved by means of rubber o rings which set in a groove between the tubes a shell flange.

This type heat exchangers a special German technology in which a continues wire or strip of fin materials is wounded spirally onto the tube and strengthened to withstand higher internal pressure comparing with radiator type, in this finned heat exchanger are having more heat transfer area is allowed to improve the efficiency. The tubes & fins are in brass, copper, cupronickel, steel, etc materials. Where low density, low heat transfer fluids are exchanged with a high heat capacity streams, finned Tube Heat Exchangers are an ideal solution. The main features of these heat exchangers are: 

• Wire wound/drilling rig compressor oil collars
• The upper/lower guide bearing coolers
• Transformer oil coolers
• Generator air coolers-wire/strip-alu370 & alu 680
• Thrust bearing coolers
• Gas coolers
• Hydraulic coolers for all engineering [oil coolers for bulldozers
• Oil coolers for excavators

A plate type heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. This has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids spread out over the plates. This facilitates the transfer of heat, and greatly increases the speed of the temperature change. It is not as common to see plate heat exchangers because they need well-sealed gaskets to prevent the fluids from escaping, although modern manufacturing processes have made them feasible.

The concept behind a heat exchanger is the use of pipes or other containment vessels to heat or cool one fluid by transferring heat between it and another fluid. In most cases, the exchanger consists of a coiled pipe containing one fluid that passes through a chamber containing another fluid. The walls of the pipe are usually made of metal, or another substance with a high thermal conductivity, to facilitate the interchange, whereas the outer casing of the larger chamber is made of a plastic or coated with thermal insulation, to discourage heat from escaping from the exchanger. The plate heat exchanger (PHE) was invented by Dr Richard Seligman in 1923 and revolutionized methods of indirect heating and cooling of fluids.

Plate type heat exchanger one is composed of multiple, thin, slightly-separated plates that have very large surface areas and fluid flow passages for heat transfer. This stacked-plate arrangement can be more effective, in a given space, than the shell and tube heat exchanger. Advances in gasket and brazing technology have made the plate-type heat exchanger increasingly practical. In HVAC applications, large heat exchangers of this type are called plate-and-frame; when used in open loops, these heat exchangers are normally of the gasket type to allow periodic disassembly, cleaning, and inspection. There are many types of permanently-bonded plate heat exchangers, such as dip-brazed and vacuum-brazed plate varieties, and they are often specified for closed-loop applications such as refrigeration. Plate heat exchangers also differ in the types of plates that are used, and in the configurations of those plates. Some plates may be stamped with "chevron" or other patterns, where others may have machined fins and/or grooves.

Liquid foods such as milk, fruit juices, beers, wines, and liquid eggs are pasteurized using plate-type heat exchangers. Wine and fruit juices are normally deaerated prior to pasteurization in order to remove oxygen and minimize oxidative deterioration of the products. Plate-type heat exchangers consist of a large number of thin, vertical steel plates that are clamped together in a frame.
 

The Marine coolers manufactured by us conform to all international and national quality standards such as TEMA and various IS standards such as IS 4503 and IS 6088. Our excellent manufacturing facility ensures the superior quality of our equipment.

Marine Coolers are the most common way to cool a boat's engine, using the lake, river or ocean water in which the boat floats. Since this water may be corrosive the engine may be cooled by a sealed mixture of distilled water and antifreeze. Heat from the water-antifreeze mixture is then transferred to the ocean (or lake or river) water which flows into a heat exchanger. The water-antifreeze mixture runs through the heat exchanger dumping heat, but remaining separate from corrosive salts and chemicals found in the water the boat is floating in. If the ocean water eventually corrodes and ruins the heat exchanger it can be replaced at a fraction of the cost of replacing the engine. To protect the marine heat exchanger from corrosive salts, a sacrificial zinc anode is screwed into the heat exchanger. This anode must be periodically replaced as part of regular maintenance.

Because the water the boat floats in may be contaminated with floating particles such as wood or styrofoam balls the well designed boat will have a filter (often stainless steel mesh) to remove these particles before they are moved toward the heat exchanger. This filter must be periodically cleaned or else the flow of water to the heat exchanger will become obstructed and the engine will overheat.

Ocean water is caused to flow through the heat exchanger by an impeller, often made of rubber and looking like a paddle wheel. Impellers commonly fail by having their paddles fall off and when this happens the engine will overheat unless promptly shut off. Many marine engines using heat exchangers have a grease reservoir for the impeller. In such cases a screw is often made part of the reservoir and is turned a small amount periodically, such as once a month, to apply a bit of grease to the rubber impeller to reduce friction and prolong its life.

A consequence of using a heat exchanger on an in-hull marine engine is that there must be a thru-hull opening below the waterline to admit the ocean water to the marine cooler. Most boats with this arrangement have a valve which closes this hole when the boat is unattended so that a leak in the cooling system will not cause the boat to fill with water and eventually sink.
