Plate heat exchangers solve problems

A recent contract to supply Covrad Heat Transfer with plate heat exchangers for power generation applications is just the latest of a long line of orders.

The recent contract to supply Covrad Heat Transfer with plate heat exchangers (PHEs) for power generation applications is just the latest of a long line of orders that the company has awarded to Tranter International.

The long running partnership is a testament not only to the comprehensive nature of Tranter's product range - given Covrad's activities in the power generation, rail traction and off-highway/commercial vehicle fields - but also to the considerable synergy that exists between the two companies forming a true partnership.

Plate heat exchangers offer a number of advantages over traditional shell and tube systems but Tranter's whole approach is a problem-solving one.

In the latest contract, with the power generation set located in the basement and radiators at rooftop level, it was necessary to isolate the two and eliminate the static head, a criterion which Tranter welded plate exchangers were ideally placed to satisfy.

The number of applications for PHEs is considerable and increasing in number with each passing year.

One of the most recent is combined heat and power, but it is worth listing some of the others.

PHEs are easily cleaned, which means in cooling applications that they can be used to isolate effectively parts of the system and protect equipment from contaminants as well increase efficiency and/or performance.

PHE units are also extremely compact and in heating applications can perform a variety of heat recovery and isolation duties as well as safely heating potable water if manufactured of stainless steel.
