Shell & Tube
We can manufacture all types of “shell and tube” heat exchangers to order. We will design and manufacture based on your requirements or select from our stock range of coolers. We can manufacture from 1m² up to over 1000 m² surface area. Quite often we can manufacture a complete unit cheaper than the replacement element cost from the original supplier. Heat exchangers in this category include:
- Lube Oil Coolers
- Jacket Water Coolers
- Fuel Oil Heaters
- Steam Drain/Dump Condensers
- Hydraulic Oil Condensers
- Steam Heaters
- Compressor Coolers (Air)
- Freon Condensers
- Fresh Water Generators
- Water Heaters (non-electrical)
- Gearbox Oil coolers
Only quality materials from reputable suppliers are used in the construction of these units. We carry a large range of stock tubes and tube plates – the majority of which are suitable for seawater use. Material selection is subject to operating parameters and conditions of use. Naval Brass tube plates with Aluminium Brass tubes are commonly found on tube bundle (elements) used in the marine industry.
We can supply completely brand new equipment, refurbish of an existing shell casing by installing a new cooling bundle element or we can supply all necessary parts in “kit form” to allow in situ refurbishment using your own staff or one of our travelling engineers. In the event the old unit is sent to our workshops, we can usually offer significant savings by reusing original parts when suitable. In some cases, we can convert heat exchangers with fixed tube plates into a “removable tube bundle” type, this allows easy maintenance, reduced cleaning costs and cheaper future replacement. For units operating in particularly harsh environments, we can offer tube inserts (to reduce tube end erosion) and protective coating of tube plates (to reduce attack due to corrosion/erosion).
We can also offer directly or via our global network of contacts, the following services relating specifically to heat exchangers:
Onboard Riding gangs to carry out re-tubing or repairs
Ultrasonic, Chemical or Vibrasonic cleaning
Repair and refurbishment locations close to many ports
All units are supplied with full material certification and are pressure tested at our workshops. Units are manufactured using proven techniques and inspected regularly throughout manufacture.
U Tube BundlesWe have numerous options available for U tube bundle construction, a selection of tube material as well as alternative baffle options such as PTFE to reduce the damaging effects of vibration. Ask us for more details.
Tube OptionsWe can supply CuNi, Naval Brass, Alu Brass and many more depending upon your requirements and application. For units subjected to high pressure environments, we can weld tube ends and conduct high pressure hydro and gas tests.
Industrial Applications & Bespoke DesignWe can take on jobs of any size up to around 6 tonnes, our design team also specialise in getting the maximum performance out of a set amount of space, ideal if installation areas are tight.
