Corrugated Tube Heat Exchangers
XLG® S TUBE-IN-TUBE - Corrugated Tube Heat Exchangers
These are corrugated tube heat exchangers formed by two concentric tubes and are especially useful for treating slurries (fluids which contain significant amounts of fibres or suspended particles) and particulate fluids (such as fruit dices).
XLG®S Tube-in-Tube heat exchangers are constructed from stainless steel and are formed by having two concentric tubes. The fluid to be treated is normally passed through the corrugated inner tube and the service fluid, providing the source of cooling or heating, passes through the annulus formed by the two tubes.
This range is formed from units of different tube diameters chosen according to the flow rates of the working fluids. Corrugated tubes are used in order to significantly enhance the rate of heat transfer and thus minimise the size of heat exchanger required.
XLG® I-SERIES - Corrugated Tube Heat Exchangers
Multi-tube heat exchangers developed for industrial applications such as steam water heating, energy recovery, condensation etc.
XLG® I-Series Industrial Multitube heat exchangers are manufactured from stainless steel. They consist of a bundle of corrugated tubes mounted within an outer tube (which forms the outer shell). The fluid to be treated (the product) flows through the interior of the tubes forming the tube bundle, while the service fluid flows outside the inner tubes, through the shell.
The range of units uses shell and inner tube diameters to satisfy the flow rates of the process fluids. The inner tubes are corrugated to significantly enhance the rate of heat transfer.
The exchanger incorporates an expansion bellows welded to the shell to absorb the thermal expansion that takes place between the shell and the tube bundle. The fluids flowing through the inner tubes (the product) and the outer shell (the service) are completely isolated from each other, with heat being transferred through the inner tube walls.
XLG® MD REGENERATOR
Multi-tube heat exchangers developed for hygienic/sanitary product to product heat recovery applications in the food, dairy and beverage industry. The fluids may also contain limited quantities of pulp and/or fibres.
XLG® MD Regenerative Multitube heat exchangers are manufactured entirely from stainless steel. They consist of a bundle of corrugated tubes mounted within a corrugated outer tube (which forms the outer shell).
The sterile fluid flows through the interior of the tubes forming the tube bundle, while the raw (not-sterile) fluid flows outside the inner tubes, through the shell.
All product wetted surfaces, including the welds, have a surface roughness Ra < 0.8 µm. They are therefore able to process food products under the normal hygiene regulations. Such processes include pasteurisation, high temperature sterilisation, and thermal treatment for aseptic packaging.
Both fluids (sterile and not-sterile) are completely isolated from each other, with heat transfer taking place across the inner tube walls. Leakage of the service fluid to atmosphere is prevented by a pair of elastomeric O ring seals at each end of the tube.
If hygiene and process conditions require it, steam packing can be provided between the O ring seals at both ends of the units. One tubeplate is fixed to the outer tube assembly while the other is free to expand and contract with the changes in temperature occurring in service. This avoids the potentially damaging stresses that occur in other types of fully welded heat exchangers that use expansion bellows to absorb the differential expansion between the shell and the inner tubes.
Connections are DIN/ISO/ASME standard ferrules and clamps or DIN food standard screwed compression fittings.
XLG® SS - Corrugated Tube Heat Exchangers
These are Tube-in-Tube corrugated tube heat exchangers specially designed for direct regeneration (product to product) between hot and cold sludge and biomass. Units are formed by two concentric tubes. The transition between units is done by means of special clogging-free headers.
XLG® GVP STEAM GENERATOR - Corrugated Tube Heat Exchangers
Packaged systems for the production of clean steam in a large range of capacities. They are used in the food and beverage, pharmaceutical, healthcare, biotechnology, electronics, and brewing industries.
XTUBE BOXER®
A new Scraped Surface Heat Exchanger specially suitable for processing high viscosity fluids or for high fouling applications.
About XLG Heat Transfer Systems:
XLG Heat Transfer was founded in 2005 by a group of engineers specialised in heat exchanger design and manufacture. They have a long professional experience in the use of heat exchangers across all sectors of industry, particularly in the Food Processing Industry, water, Environmental Control, Automotive, Chemical, Pharmaceutical, Shipbuilding, and many other diverse industrial applications.
COMPANY
XLG is a company specialised in optimising both the designs and the final quality of the heat exchangers that they produce. Their corrugated tube heat exchangers exemplify maximum thermal performance, high mechanical strength, and reliability.
PERSONALISED SOLUTIONS FOR YOUR INDUSTRY
XLG always offers its clients, partners, and distributors the best solution for whatever application they require. This means that they offer products from their own comprehensive range which are the best type and size of unit to solve the heat transfer problem, whilst being most advantageous in terms of first cost and running costs.
To achieve this, the professional engineers of XLG study each enquiry in detail for every application. They select the best type and size of heat exchanger to achieve maximum performance at the least cost to the client.
KNOW-HOW
XLG designs all of its heat exchangers using in-house developed software for both thermal and mechanical design.
All heat exchangers supplied by XLG comply with the European Pressure Equipment Directive 97/23/EC. XLG is authorised to apply the 3-A Symbol from the United States as they conform to 3-A Sanitary Standards. The XTube Boxer® units also comply with the Electromagnetic Compatibility Directive 2004/108/EC, the Low Voltage Regulations 2006/95/EC, and the Machinery Directive 98/37/EC.
When we are permitted to do so, we CE mark our equipment as required by the various Directives.
All heat exchanger manufacturing processes use the most modern techniques and equipment. Our welders are highly qualified and experienced, with certification for all processes and techniques employed.
