Plate Heat Exchangers Information
Plate Heat Exchangers
We know heat exchangers!
With over 25 years combined working with the OLAER / OILTECH Group we know their water / oil cooler (heat exchanger range) whether you have an PWO B or K series plate coolers to the SW, ST1, EM1 and EL3 shell and tube series Exotech can size and answer any of your techical questions.
Compact Design, Big Performance
The EPC is a brazed plate water oil cooler, it’s a compact and lightweight oil cooler with a high cooling capacity compared to size. This lightweight and compact water oil cooler consists of corrugated channel plates sandwiched between the front and rear cover plates.
The heat transferring surfaces consist of acid-resistant stainless steel plates. Every other plate is turned by 180 degrees and placed on the preceding plate. The channels between the plates allow the media to flow counter current. By brazing the special plate profiles together the numerous contact points allow for very high operating pressures.The unique plate design provides high turbulent flow conditions throughout the cooler, the key to efficient cooling. This turbulent flow reduces the risk for clogging, which in turn makes this EPC virtually maintenance free.
EPC water oil cooler is ideal for use in stationary lubricating systems, hydraulic applications and an excellent choice for replacing shell and tube units on injection moulding machines. Where the minimum of space is required and the heat transfer capacity is very high.
WATER OIL COOLER OPERATION
EPC provides an oil temperature very close to the cooling water temperature, eliminating the need for an active cooling system in certain applications. The EPC design features result in a turbulent oil and cooling water flow, the key to high cooling capacity. This turbulent flow prevents clogging, a frequent cause of reduced heat transfer efficiency. The EPC cooler provides reliable temperature control of oils, a condition for maximum performance.
BENEFITS
- Low water consumption – economical in operation
- Turbulent flow – prevents clogging – reduced maintenance
- Compact – small installation dimensions – easy assembly
Freshwater is vital for all life but the global supply is limited. Despite this, we continue to waste water. Obsolete technology is still used in systems for cooling oil with freshwater. But there is an alternative.
Plate type heat exchanger is the new technology available today, the hydraulic oil cooler of tomorrow. A technique which means that less of the world’s freshwater goes to waste.
LOW PRICE WITH WATER
Water and air, naturally occurring, environment-friendly and inexpensive are the coolants with which we work. Water oil coolers are used in the majority of stationary hydraulic systems because the cost is low, the cooler occupies little space and cools effectively. Because of its low cost, the water oil cooler can be over-sized to be able to cope with possible increased future cooling demands or peak loading due to, for example, clogging and impair system efficiency.
LOW TEMPERATURE
The EPC water oil cooler works with water inlet temperature which is often lower than room temperature. It can therefore be used to maintain the oil temperature. It can therefore be used to maintain the oil temperature at a very low level. It also withstands extreme environmental conditions. If the room temperature is too high, an air oil cooler may be unable to cool the oil satisfactorily and a water oil cooler is then preferable. Plate type water oil coolers ensure quiet operation and are more compact than comparable coolers using air as coolant.
EFFICIENT OPERATION
Off-line circuits for cooling and filtration increase the service life of both the hydraulic system and the oil. A careful sizing of the water oil cooler also reduces cooling water consumption providing cost-effective operation and efficient use of resources. A turbulent flow reduces the risk of clogging as the cooler is continuously self-cleaning. The rugged construction of the PWO-cooler lowers the risk of contamination of the hydraulic oil with water.
SECONDARY ADVANTAGES
Direct savings are obtained when a water oil cooler from Oiltech is installed in your system. And use can be made of the surplus energy resulting from the cooling process. The heated cooling water is often used for pre-heating water for other purposes. The special properties of Oiltech’s water oil coolers make them ideal for a variety of tasks in many kinds of installations and working environments. WEGO and PWO are the designations of our oil coolers which, with different capacities, constitute a complete program to cover all requirements.
OUR MAIN WATER OIL COOLERS
PWO Braced plates heat exchangers
ST Industrial Shell and Tubes cooler
EM1 Industrial Shell and Tubes cooler
EL3 Marine Shell and Tubes cooler
PULP AND PAPER INDUSTRY
Compact design, reduced maintenance and outstanding heat transfer economy are all important reasons for considering a PWO water oil cooler in your application. Olaer is marketing special-made water oil coolers for various pulp and paper industry applications.
MOTOR CAR INDUSTRY
The PWO water oil cooler have many similarities to the principles in the motor car industry, e.g. adaptability to customers needs with maintained prices, using standard components for specially made products. Olaer is marketing water oil coolers, adaptable to a wide range of applications within the motor car industry.
STEEL AND METAL INDUSTRY
From heat to cold steel, an immense quantity of thermal energy is required to transform iron ore to casting pigs, sheet metal and tubes. A great deal of this heat is transformed into gas or vapour. Besides, heat is absorbed by the walls of the blast furnace, presses and moulds as well as by the tempered oil, quench water, lubricants and other fluids, which all require cooling.
Similar conditions prevail when making aluminum, copper and many more metals. Olaer’s high quality water oil cooler provides fast and high-efficient cooling. Our expertise can show you at the same time as meeting your requirements.
PLASTICS INDUSTRY
The chemical industry shows the highest variation of applications using water oil coolers. Olaer can supply a broad range of water oil coolers to match the requirements from every specific application with great accuracy, even when extremely sophisticated and very resisting materials are used.
