Sanitary Heat Exchangers

Spiral tube type heat exchangers are fabricated from coiled tubing. In some cases the tubing is installed inside a fabricated bundle to provide a compact stand alone heat exchanger. These exchangers are used primarily for small services such as pump seal fluid and sample coolers. Advantages

Spiral plate heat exchangers are fabricated from two metal plates that are wound around each other. One process fluid stream enters the exchanger at the centre and flows outwards while the second fluid enters on the outside and flows inward. This creates almost a true counter current flow. Advantages Typical Applications

Advantages Very compact design High heat transfer coefficients (2 – 4 times shell & tube designs) Expandable by adding plates Ease of maintenance Plates manufactured in many alloys All connections are at one end of the exchanger Good temperature approaches Fluid residence time is very short No dead spots Leakage (if it should occur) is...

A plate and frame heat exchanger is a compact heat exchanger where thin corrugated plates are stacked in contact with each other, and the two fluids flow separately along adjacent channels in the corrugation. The closure of the stacked plates may be by clamped gaskets, brazed (usually copper brazed stainless steel), or welded (stainless steel,...

The hairpin heat exchanger design is similar to that of double pipe heat exchangers with multiple tubes inside one shell. The design provides the flexibility of a U-tube design with an extended shell length that improves the exchanger’s ability to achieve close temperature approaches.   Advantages Good counter current or co-current flow –...

Double pipe heat exchangers are the simplest of all types. They are fabricated from two pieces of pipe – one inside the other. One fluid flows through the inner pipe while the second fluid flows through the annulus between the pipes Advantages •Inexpensive •True counter current or co-current flow •Easily designed for high pressure service...

Shell and tube heat exchanger The principle components are: •shell •shell cover •tubes •channel •channel cover •tube sheet •baffles, and •nozzles Other components include tie-rods and spacers, pass partition plates (channel partitions), impingement plates, longitudinal baffles, sealing strips, and supports

Shell and tube heat exchangers have the following advantages:

Shell and tube heat exchangers are known as the work-horse of the chemical process industry and represent the most widely used vehicle for transfer of heat in industrial applications. In essence, a shell and tube exchanger is a pressure vessel with many tubes inside of it. One process fluids flows through the tubes of the […]

Oil cooling is commonly used to cool high-performance motorcycle engines that are not liquid-cooled. Typically, the cylinder barrel remains air-cooled in the traditional motorcycle fashion, but the cylinder head benefits from additional cooling. As there is already an oil circulation system available for lubrication, this oil is...

Oil cooling is the use of engine oil as a coolant, typically to remove surplus heat from an internal combustion engine. The hot engine transfers heat to the oil which then usually passes through a heat-exchanger, typically a type of radiator known as an oil cooler. The cooled oil flows back into the hot object […]

The Oil Cooler heat exchangers are most suitable for clean water low in lime, for example with a closed cooling circuit. Our PHE, oil-water cooler is provided with painting appropriate for marine applications (CDP + powder painting). Applications are as follows: It is possible to use other media, for example oil, water glycol, water, refrigerants,...

The oil cooler is arranged in the circulating oil circuit of the lubrication system. Full-flow (also known as water-cooled oil cooler) is actually a liquid-liquid heat exchanger. The heat is oil and the coolant is water. Typically, the oil in this heat exchanger enters the tube and the water enters the shell.   Oil/water coolers […]

Material of Construction for Lube Oil Coolers is as follows Shell: Carbon Steel, SA106 Gr.B, IS 3589 ERW, SS 304 or SS 316 Tubes: SS 304, SS 316, Admiralty Brass, Copper, CuNi 90/10, CuNi 70/30 Tube sheet: IS 2062 Gr.B, SA 516 Gr.70, Naval Brass, AB-2, SS 304, SS 316 Baffles: Brass, Carbon Steel, SS […]

shell and tube heat exchangers offer various benefits such as versatility, durability, compact size, and cost-effectiveness. As a result, these heat exchangers are widely used in industries such as oil and gas, chemical processing, food and beverage, and power generation

An oil cooler is a separate, smaller radiator to an engine’s main radiator, which maintains an oil supply at a consistent, optimal temperature. Its purpose is to cool the oil passing through the coils, thus improving the engine and the transmission’s lifetime. They are situated in front of an engine’s cooling system.

The three most common types of shell-and-tube exchangers are (1) fixed tube sheet design, (2) U-tube design, and  (3) floating-head type.    In all three types, the front-end head is stationary while the rear-end head can be either stationary or floating , depending on the thermal stresses in the shell, tube, or tube sheet, due...

 A heat exchanger consists of heat transfer elements such as a core or matrix containing the heat transfer surface, and fluid distribution elements such as headers, manifolds, tanks, inlet and outlet nozzles or pipes, or seals. Usually, there are no moving parts in a heat exchanger; however, there are exceptions, such as a rotary regenerative...

SHELL AND TUBE HEAT EXCHANGERS are the most commonly used heat exchangers in oil refineries and other large chemical processes.are used when a process requires large amounts of fluid to be heated or cooled.provide transfer of heat efficiently.use baffles on the shell-side fluid to accomplished mixing or turbulence.

A heat exchanger is a device that is used to transfer thermal energy (enthalpy) between two or more fluids, between a solid surface and a fluid, or between solid particulates and a fluid, at different temperatures and in thermal contact. In heat exchangers, there are usually no external heat and work interactions. Typical applications involve...

A regenerative heat exchanger, or regenerator, is a type of heat exchanger where heat from a hot fluid is stored in a thermal storage medium and then transferred to a cold fluid. This is achieved by having the hot and cold fluids alternately pass through the same channels, washing the same surface area. Unlike recuperative heat...

A tubular exchanger is a type of heat exchanger with tubes encompassed in a shell. It is a very common device in industries where the focus is recovering heat from gas or liquids. The principle of the shell and tube heat exchanger is based on a bundle of tubes that is arranged vertically or horizontally […]

A flue gas cooler is a heat exchanger that lowers the temperature of flue gas, which is the exhaust gas from combustion processes, before it is released into the atmosphere. This is often done to recover waste heat, reduce emissions, or prepare the flue gas for further treatment.         Here’s a more […]

A syngas dehumidifier removes water vapor from syngas (synthesis gas) to improve its quality and prevent issues in downstream processes like power generation or chemical synthesis. It’s crucial for removing moisture which can cause corrosion, reduced efficiency, and operational problems in systems using syngas.   What is Syngas? Syngas...

Biogas Dehumidification System (BDS) reduces biogas temperatures from around 40ºC to approximately 5-7ºC, condensing more than 90% of the water volume. It works via a chiller system which supplies a coolant that is transferred to heat exchangers. Biogas flows on the product side of the exchanger, while the coolant flows on the service side. More...
