XTRAN® Heat Exchangers : The XTRAN® heat exchanger is of shell and tube configuration, arranged singly or as a multi-module system. Modular Shell and Tube Heat Exchanger : Fully owned by RareTechSEA since 2012, the XTRAN® Heat Exchanger is a unique design concept in Modular Shell and Tube Exchangers. It has been manufactured in South Africa since 1979 under licence from the original Swiss designer. Originally covered by international patents, this modular approach to heat transfer technology incorporates features not available in other heat transfer equipment. A Unique Design Concept in Modular Shell and Tube Heat Exchangers : All tubes are straight and are not expanded or welded into the tube sheets but sealed under compression using elastomeric seals allowing the XTRAN® Heat Exchanger to be completely dismantled if required. The shell side cage design incorporates a unique baffle arrangement that provides uni-directional spiral flow in the shell thereby eliminating dead spots and flow reversal which also reduces fouling. Separate headers with an airgap are used for tube pass and shell pass fluids which prevents contamination if a leak were to occur.

Simple Maintenance Procedures for Extended lifespan : The unique design of the XTRAN® Heat Exchanger allows complete dismantling without the use of special tools. Individual tubes can be withdrawn and replaced which greatly eases inspection and cleaning. Caps are removable for tube cleaning without having to disconnect pipe work. Component parts are readily available ex-stock to enable repairs to be carried out simply and effectively with a minimum of downtime.

Customisable, Flexible Design : The variable shell side cage geometry allows the shell side fluid velocity to be accurately determined and selected to affect the maximum heat transfer and at the same time ensuring efficient removal of condensed moisture or steam condensate when this is required. Being of modular construction the overall size of the heat exchanger can be altered by the addition or reduction of modules thereby matching the size of the exchanger to the required duty. This enables plant expansion to be accommodated without the need of replacing heat transfer equipment. An outstanding feature of the design is that individual tubes, or the complete tube bundle, can be removed and replaced in-situ without disconnecting related pipework.
