Water-oil heat exchangers are shell and tube type. they permit to waste the heat in hydraulic plants. They can operate on exhaust line of the main hydraulic circuit, or on a separate circuit dedicated to cooling

WATER-OIL HEAT EXCHANGERS WITH TUBE BUNDLE
They consist of small diameter smooth tubes; this allows the best compromise between high thermic yield and low pressure loss. For a good exchanger practices some oil rates are indicated in the tables. Going down to the lowest rate of flow, indicated in the tables, the low oil speed causes a great loss in yield, whereas a rate of flow which is superior to the maximum indicated, causes great pressure loss and does not considerably increase the thermal yield. The yield diagrams indicate the heat quantity each exchanger can disperse according to the difference between oil and water mean temperatures. Such diagrams assume the exchangers to be working with the maximum oil rate indicated in the table. With the minimum rate, the yield decreases by about 10%. Required water volume is a follows:
85 l/h for each kW to disperse with water temperatures (20°C)
170 l/h for each kW to disperse with higher water temperatures

On the heat exchangers PICKER, connections of the fluids are carried out according to families' of exchangers :
> By tapping known as "cylindrical gases" carried out in the element and/or the lids (usually for connections until 1"1/4).
> By counter-flanges of our standard, usually delivered "full" with joints and screws and bolts (for connections welded, brazed or screwed).
With additional charge, the machining of the counter-flanges can be carried out by our care (only borings or tapping "cylindrical gases"). This option must be mentioned with the order by indicating the desired diameters.

As a type of screwed plate device, the module welded plate heat exchanger has greatly expanded the field of application of this type of heat exchanger. Alongside the 'classic' exchange of heat between liquids, screwed plate apparatuses also cover applications at high operating pressure and / or phase transitions in the flow gap. One 'module' consists of two heat exchanger plates of the same size which are welded together by lasers. This laser welded seam is resistant to both high levels of static pressure and the changes in pressure commonly occurring. Since no additional material is used to weld the plates, more frequent changes in temperature can also be tolerated. The laser welded seam reduces the remaining seal length (seal between module A and module N) to 10 % of the seal length of a gasketed apparatus. It is financially advantageous to also use expensive special elastomers where necessary for the remaining ring gaskets.

All heat exchangers are assembled in modules. The size is determined mainly by the gas flow and output and, to a lesser extent, by the parts.
The most important features are:
* Materials of PE, PP, PVDF
* Allowed operating temperature is from -30° C to + 140° C depending on the material selected
* Allowed operating pressure is between 3 and 16 bar depending on the material selected and the operating temperature
* Gas flow rate up to 150,000 Nm3/h per heat exchanger
* Outer pipe diameter 6 mm; wall thickness of 0.6 mm

Schmidt Brazed Plate Heat Exchangers
Brazed Plate Heat Exchangers represent the most compact, rugged and cost-effective means of transferring heat in many industrial and refrigerant applications. Built from 316 stainless steel with copper brazing materials, they provide exceptional corrosion resistance. The SB-Series features corrugated plates that produce highly turbulent flow in a true counter-current direction. This results in high efficiency and a very compact heat exchanger design. Due to the smaller size and reduced material content, they can be the most economical heat transfer choice.

- Developed more than 50 years ago to meet the needs of the aeronautics industry, where compactness, light weight and efficient heat exchanges are essential qualities, brazed aluminium plate-fin heat exchangers now have an excellent reputation in the gas processing industry following enhancements which have added to their initial qualities to meet the requirements of process engineers, investors and producers.
Fives Cryogenie brazed aluminium plate-fin heat exchangers offer the possibility of integrating various processes (up to 20 fluids flowing simultaneously through a single heat exchanger) over a wide range of dimensions.
Fives Cryogenie brazed aluminium plate-fin heat exchangers are especially suitable for processes requiring a high level of heat transfer under low temperature difference (1°C to 2°C or less) between warm and cold fluids.
- Some typical applications:
- Separation of air gases
- Hydrocarbon processing
- Natural gas liquefaction
- Industrial gas liquefaction (oxygen, nitrogen, argon, helium, etc.).
- Through continuous improvements in the performance of modern processes, Fives Cryo is at the top of development in the fields of fluid dynamics, design and simulation of equipment.
- The numerous component parts of a heat exchanger are manufactured with the greatest care and asembled by vacuum brazing. Our fully automated brazing facilities optimize the brazing process with outstanding reliability, whatever the size of the heat exchangers.
Inspection / QC means, using up-to-date technology, ensure the product's impeccable quality.

Schmidt Gasketed Plate Heat Exchangers
SIGMA Plate Heat Exchangers utilize corrugated plates stacked between a fixed and a movable pressure plate. The corrugation patterns alternate for maximum operating pressures. As virtually all of the material is used for heat transfer, Plate Heat Exchangers can have large amounts of effective heat transfer surface in a small footprint. It is not uncommon that a Plate Heat Exchanger will have the same thermal capacity as a Shell & Tube five times larger.
The unique corrugation pattern pressed onto each Schmidt thermal plate produces the highest overall heat transfer rate by assuring highly turbulent flow and excellent fluid distribution across the entire surface. With high heat transfer rates and true counter current flow, Schmidt Plate Heat Exchangers economically handle close temperature approach requirements.

Schmidt Semi-Welded Plate Heat Exchangers
API Heat Transfer Semi-Welded plates feature plates that are welded using advanced laser welding techniques. Two plates are welded together and are fitted with a Viton® O-Ring and/or Teflon® gasket liner. The resulting plate pack has every other plate fully serviceable, while maintaining integrity of the welded plate pair.
This is especially suitable for critical fluids and gases, such as ammonia or caustic process chemicals where fluid loss is not acceptable. In the case of ammonia refrigeration, the reduced volume results in significant savings.

Our Shell and Tube Heat Exchangers are designed to transfer heat efficiently and effectively while reducing fuel consumption. A Heat Exchanger can be combined with any of our other systems or as a retrofit. In addition, Epcon has several designs that combine burnerless ovens with Thermal Oxidizers.
The price of the fuel necessary to run a Thermal Oxidizer can be exorbitant. In order to lower operating costs, a heat exchanger can be used. Heat Exchangers are used for transferring heat from one fluid (such as air) at higher temperature to another fluid at a lower temperature, thus making use of heat which would otherwise be expelled. In the various systems manufactured at Epcon, heat exchangers are used for the following purposes:
1. Pre-Heating the process gas as it enters the thermal oxidizer (also called Primary heat exchange). The heat is transferred from the hot gas leaving the combustion process to the cold air entering it. The two basic methods are Regenerative and Recuperative.
2. Using the gas for Secondary heating systems, such as process heating of the manufacturing facilities and heating boilers.
