Double pipe heat exchangers are the simplest exchangers used in industries. On one hand, these heat exchangers are cheap for both design and maintenance, making them a good choice for small industries. On the other hand, their low efficiency coupled with the high space occupied in large scales, has led modern industries to use more efficient heat exchangers like shell an
Water cooling heat exchangers (WL, LA and WW Series) are designed to circulate water or a water glycol (antifreeze) mixture and keep the temperature of the coolant at or near ambient. The WL/LA Series is a recirculating liquid to air heat exchanger that offers
3 · Heat exchangers are used to transfer heat energy from one fluid to another in order to control the temperature of a system or substance. Heat exchangers contain two streams of fluid, one hot and one cold,
Heat exchangers are commonly used in applications such as heating water, cooling air, and recovering waste heat from industrial processes. The primary purpose of a heat exchanger is to improve energy efficiency by maximizing the transfer of
System Water-to-Water Heat Exchangers. Take advantage of an existing in-house water system for heat removal. Thermo Scientific System Water-to-Water Heat Exchangers use less energy and cost less to operate than traditional compressor-based chillers. They provide a clean, stable, controlled, closed-loop water cooling system that rejects the
3 · In cooling applications, the hot medium is the target fluid being cooled (e.g. steam); in heating applications, the hot fluid is the heat transfer medium (e.g. water). The cold side medium or fluid is the fluid that enters the heat exchanger at a lower temperature.
In this unit, a coolant fluid enters the exchanger at 26 C (78 F) and leaves at 43 C (110 F), taking heat from water that enters at 59 C (137.5 F) and leaves at 43 C (110 F). Photo by R.G.

Water heated in the heat exchange process can be handled in one of two ways. The water can be discharged at the increased temperature into a receiving body (once-through
Heat exchangers transfer heat between two or more gases or fluids by containing one of them within the other so that they are in contact but do not mix. For example, a typical water shell and tube heat
As a leading UK manufacturer of shell and tube heat exchangers and oil coolers, Bowman offer one of the widest product ranges available covering a multitude of water-cooled applications. Backed by 100 years of heat transfer experience, Bowman heat exchangers can today be found in some of the most extreme and demanding applications known
where r 0 denotes evaporation heat of water at 0 C, and it equals 2501 kJ/kg.3.2 Evaporative Cooling ProcessEvaporative cooling process can be well illustrated and understood on a psychrometric chart. Figure 1 shows an example of a psychrometric chart, which is drawn with dry bulb temperature in horizontal axis and humidity ratio in
In large-scale cooling water systems for heat exchangers, water treatment such as purification, addition of chemicals, and testing, is used to minimize fouling of the heat exchange equipment. Other water treatment is also used in steam systems for power plants, etc. to minimize fouling and corrosion of the heat exchange and other equipment.
Finned Tube Bundle Shell & Tube Water to Oil Cooling. The EK Series – the ''Green'' cooler – is the most efficient heat exchanger offered in the water cooled series. The aluminum finned tube bundle design provides an increased surface area that allows for optimal heat rejection with low water usage. An optional Surge-Cushion ® bypass is
Using water cooled heat exchangers allows the process to be cooled to temperatures not achievable by air cooled heat exchangers which are limited by the ambient climatic conditions. Also, water cooled heat
Water cooling Shell-and-tube heat exchangers, Figure 2, have an outer flanged shell with end bonnets appropriately sealed to the shell ends. A precise pattern of tubing within the shell runs the length of the shell and terminates in
A heat exchanger is a system that transfers heat between substances, through the movement of a cooling medium (fluid or air). They are used for both heating and cooling in a wide range of industrial applications: power stations, computer processors, chemical plants, food and beverage processing, refineries, refrigeration, space heating/cooling,
Common applications of heat exchangers in the nuclear field include boilers, fan coolers, cooling water heat exchangers, and condensers. The basic design of a heat exchanger normally has two fluids of different
For water cooled shell-and-tube heat exchangers, the shell is often carbon steel, with higher-grade materials for the tubes. In a steam condenser, potential tube materials include admiralty brass (70% copper, 29% zinc with minor additional elements), 90-10 copper-nickel, 70-30 copper-nickel, and more recently the 300-series stainless steels.
The answer lies in its use of cross-counterflow sub-cooling. This technology enables the heat exchanger to capture both the latent heat and the sensible heat from the steam condensate. The result is an incredibly efficient system for generating hot water from steam. Shell & coil heat exchangers, like the Cooney Thermo-Pack, are an evolution in

Liquid Heat Exchangers: Standard Flat Tube Heat Exchangers. Boyd''s standard flat tube liquid heat exchangers have aluminum fins and flow paths, with 3/8 – 18 NPT fittings, and pre-installed fan plate. Customers have the option of adding a fan kit with their heat exchanger, with either 115V or 230V fans. Max. operating temperature: 200°C
Heat exchangers are devices designed to transfer heat between two or more fluids—i.e., liquids, vapors, or gases—of different temperatures. Depending on the type of heat exchanger employed, the heat transferring process can be gas-to-gas, liquid-to-gas, or liquid-to-liquid and occur through a solid separator, which prevents mixing of
A heat exchanger is exactly what the name implies, a device used to transfer (exchange) heat or thermal energy. Heat exchangers are either given a hot fluid to provide heating or a cold fluid to provide cooling. A fluid can be either a liquid or a gas. Heat always flows from hot to cold.
For example, a typical water shell and tube heat exchanger setup enables a pipe of hot wastewater to be cooled by placing that pipe inside a wider shell or tank of colder freshwater. As the two
Place these heat exchangers in open tanks to heat or cool their contents by transferring heat from water or steam that flows through passageways in the panel.
Air Cooled Heat Exchangers consist of bundle of tubes, a fan system and supporting structure. The tubes can have various type of fins in order to provide additional surface area on the air side. Air is either sucked up

Core tubes may be carbon steel, stainless steel or various alloys and are usually of 25.4 × 10 −3 m outside diameter. For low pressure or highly viscous applications the tubes can be up to 50.8 × 10 −3 m diameter. Tube lengths vary to suit the installation, which will often be over a piperack, but generally do not exceed 15 m.
