Air fin coolers
A device in which a fluid is cooled by ambient air; the fluid is separated from the air by finned tubes. Airfin cooling installations are a common piece of equipment in modern petrochemical, oil & gas facilities and power plants. Air is a clean, free, non-corrosive cooling material, which does not have to be treated. Moreover, air is an unlimited resource. Heat Exchanger Service specialises in the manufacturing of new installations in all available special materials. In addition, we have the expertise and all the necessary equipment to upgrade, overhaul and even re-tube large cooling installations.
Double pipe exchangers
In its simplest form, the double pipe heat exchanger, (also known as a concentric pipe, hairpin, jacked pipe and jacketed U-tube heat exchangers), consists of a single tube mounted inside another. One fluid flows in the inner pipe, while a second fluid flows in the outer pipe annuals. Heat Exchanger Service can supply a full range of services from thermal and mechanical design through to complete manufacture.
Shell & Tube exchangers
A device in which energy (heat) is transferred from a hot fluid to a colder fluid. The fluids are separated by a wall, and cannot mix. A heat exchanger is a relatively straightforward product in almost every industry. It is, however, not a piece of equipment to take for granted. Thanks to our know-how and experience, we have proven ability to improve the efficiency of any kind of heat exchanger dramatically. Our years of experience have provided us with specialised know-how, which plays a significant role when it comes to perfect advice. Whether you are an engineering consultant or an end user, we will gladly share our knowledge.
Heat Exchanger Service builds tank heaters for many different applications. We offer either the bundle by itself, or we offer the entire tank heater assembly which includes: the bundle, cast or fabrication head, and sleeve which the bundle slides into. We have very few limitations on length or diameter and can size your tank heaters to match your existing tank. Heat Exchanger Service also offers the same wide variety of materials for tubes and tubesheets that we offer for our tube bundles.
This is a container for process fluid. Heat Exchanger Service knows pressure vessels and knows how to make them – from relatively small ones to really large ones. We build pressure vessels for clients in the chemical and petrochemical industry as well as for research institutes and power plants.
