Shell & tube heat exchangers - Import export

We design and manufacture products based on the project sent by our customers or according to customer requirements. Calculations, designs and projections according to customer demand and in accordance with ASME Code Section VIII Div 1 and 2 (American Society Mechanical Engineers), API 661, API 650 (American Petroleum Institute), TEMA (Tubular Exchanger Manufacturers Association), AD-MERKBLAATTER, CODAT, DIN, EN 13445, PED 2014/68 / AB and TSE. The most common processes in the Oil & Gas, Petrochemical & Chemical, Food & Beverages and Heavy & Light Industry require a significant number of equipment to exchange heat or to storage different fluids or components. The fluid can be either liquid or gas, and one of each flows into the tube and the other flow out of the tube is used to boil, condense or cooling the fluid.

IT IS THE MOST WIDELY USED HEAT EXCHANGER IN INDUSTRIAL FACILITIES SUCH AS IRON AND STEEL, PETROLEUM, PETROCHEMICAL, GAS, POWER PLANTS, FOOD, PHARMACEUTICALS, LEATHER, TEXTILES, AIR CONDITIONING, SHIPS AND MARITIME SECTORS THE HEAT EXCHANGERS USED IN THE INDUSTRIES CAN BE USED IN ALL SECTORS WHERE THERE IS A SECOND ALTERNATIVE ENERGY REQUIREMENT FROM AN ALTERNATIVE ENERGY WHILE ONE FLUID RUNS THROUGH THE TUBES, OTHER FLUID FLOWS OUTSIDE THE TUBES BUT INSIDE THE SHELL AS PARALLEL OR ACROSS THE TUBES. SO, HEAT IS TRANSFERRED OVER TUBE SURFACES. IT CAN BE PRODUCED AS COPPER TUBE, BAFON TUBE(CU-NI), STAINLESS STEEL AND STEEL.

A Box Cooler is a vessel water cooling system. It comprises a U-tube bundle that is fitted in the sea chest on the side of a vessel, saving space in the engine room. The sea chest is equipped with inlet and outlet grids. Cooling sea water enters through the inlet grid and flows along the U-tube bundle to the outlet grid, thus cooling the water inside the tubes. The cooling effect is achieved by the forced circulation of sea water when the vessel is moving or by natural convection when it is stationary. Box coolers can be used for a wide variety of temperature-reducing duties on a vessel, from cooling the main engines, auxiliary engines and bow thrusters to air conditioning and hydraulic systems. Kelvion Box Coolers are ideal for small and medium sized vessels, including for example: tugboats, barges, fishing boats, carriers, dredgers, supply vessels, ferries, ice breakers, cargo freighters, tankers and reefers.

Double tube safety heat exchangers play an important role in applications where preventing media mixing in the event of a leak is paramount. They are widely used and accepted as standard in the chemical industry, power, heavy and light industry, oil & gas, marine, transportation, refrigeration and food & beverage sectors. Kelvion has a long track record in developing ground-breaking technologies always aiming to reach the highest levels of safety, environmental protection and cost-efficient operation. Our expert engineers are fully trained to provide you with the best-in-class solutions tailored to your specific requirements. As industries face ever stricter regulations for safeguarding requirements of environment and water supply, double tube safety heat exchangers are the technology of choice.

Optimization of the global efficiency of a power plant based on the Rankine Cycle, requires the incorporation of highly specialized equipment that supports the maximization of the efficiency of the steam cycle, reducing the primary energy consumption, minimizing the environmental impact and helping to optimize the OPEX and consequently the return on the investment. The highly increasing competitiveness among the different centralized electricity generation technologies and the increasing concern on environmental issues, force all the available generation technologies to improve their efficiencies, reducing the primary energy consumption.

Different applications require different designs for an optimal fit, so we provide Shell & Tube heat exchangers in single tube design with plain, low and high fin tubes and also with compact fin bundles. The plain tube design is most suitable if media have similar heat transfer properties, where the compact fin design means the best possible performance if there is a substantial difference in heat transfer rate, for example when exchanging heat between oil and water. The low and high fin single tube solution is between the previous two designs in order to further optimize on flow, pressure drop and velocities of media.

Fine Tubes leads the manufacture of precision tubes required in the fabrication of shell and tube heat exchangers. Our heat exchanger tubes are used for the cooling, heating, or re-heating of fluids, gases, or air in a diverse range of industries. Alloys Fine Tubes heat exchanger products are produced as seamless, welded or welded redrawn tubes in the following materials nickel alloys, stainless steels, duplex, super duplex. Please note that we have a minimum order value of £10,000.

Shell & tube heat exchangers are manufactured with a bundle of tubes inside a shell.

There are two different construction types.   It's possible to create a design using a  little construction space using the customer's data. The Thermo-Fluid S is connected directly between the oven pipe (or the heating system) and the chimney.  The operating temperatures are up to 300°C (standard). The Thermo-Fluid S is low maintance with low pressure drop in the flue gas. Depending on the application you can have energy savings up to 15 %.     A bigger construction is the Thermo-Fluid M, which is optimised for utilisation of waste heat from process air, flue gas or exhaust air. An energy yield of up to 1600 kW is possible, whereupon the pressure drop in the process air is less than 1.5 mbar. The pressure drop in water circuit is less than 200 mbar.   This Shell and Tube heat exchanger is low maintance using the small type of construction. The Thermo-Fluid M modular and the standard temperatures are up to 300°C too.    Both Shell and Tube Heat Exchangers are low maintance. One-off or

The UniWeld combines the advantages of conventional shell and tube heat-exchangers with spiral and plate heat-exchangers due to its design and construction. This mixed construction is based on the design of the heat-transfer channels, which are on one side in the tube design and on the other side in a plate heat-exchanger. UniWeld Hybrid exchangers utilise in this way the advantage of tubular heat-exchangers (high temperature, pressure resistant and solid construction) and plate heat-exchangers (high heat transfer, minimal space and low logarithmic temperature difference) in a compact system. Other advantage compared with gasketed plate heat-exchangers is the safe splitting of the 2 media at pressures up to 80 bar and between -200°C and +900°C.

High capacity liquid-cooled chillers with the cooling power from 140 kW to 2 MW are perfectly suitable for medium to large industrial or large commercial applications. These chillers can be integrated with a dual liquid system, where the condenser uses glycol mixture and the evaporator uses water for the refrigeration process. Due to the glycol-free ability, CS chillers are ideal for particularly sensitive equipment that requires refrigeration with clean, distilled water. CS chillers are assembled on a welded open frame, equipped with maximum 4 screw compressors and shell and tube heat exchangers. Usually stored in special technical rooms and connected to secondary devices such as cooling towers or dry coolers to reject the absorbed heat to an additional fluid loop. Refra manufactures modern devices using plug-and-play ideology, making the installation and use of the devices as easy as possible.

High capacity condenserless chillers with the cooling power from 140 kW to 2 MW are perfectly suitable for medium to large industrial or large commercial applications. These chillers are mounted with a separate remote condenser that is built outdoors. The rest of the equipment is installed in a special technical room in the building. Refra can offer a condenserless chiller that can be connected to an existing condenser or a complete system with Refra condensers. CS Condenserless chillers are assembled on a welded open frame, equipped with maximum 4 screw compressors and shell and tube heat exchangers. They are usually chosen when there are sound restrictions in the project. The louder part of the system is built in an isolated room and the quiet condenser is built on the roof. The whole system is connected by a pipeline for refrigerant circulation and absorbed heat rejection. Refra manufactures modern devices using plug-and-play
