Lytron's ES Series aluminum oil coolers are engineered for high performance with poor heat transfer fluids such as oils and EGW. The extended surface flat tube design provides 2.5 times better performatnce than competitive units. The unique flat tube and header designs result in lower pressure drop so smaller, less expensive pumps can be used. Welded headers are pressure tested to 150 psi (10.3) bars and the fluxless, vacuum-brazed core provides strength and reliability. The Aluminum Oil Coolers are available with or without a fan plate, and with finish options of aluminum or black paint.

DIRECT CURRENT AIR-OIL HEAT EXCHANGERS:
This series of heat exchangers is particularly useful in cooling oleo-hydraulic plant on mobile machinery as it is fitted with direct current 12 or 24 V electric fans. The cooling element is in aluminium, a material of high thermal conductivity, which provides high thermal yield from relatively contained dimensions. The particular conformation of the radiant block is such that APL series heat exchangers are highly resistant to the stress produced by hammering which, however, at peak value, should not exceed the maximum dynamic pressure of 20 bar. The maximum permitted static pressure is 35 bar.

The heat exchangers PICKER are manufactured with following building materials, according to families of exchangers. This list is not exhaustive, to refer in the overall plans of the apparatuses to know the possible material combinations for a given family of exchangers. The choice of such or such material is mainly dictated by nature, the temperature and the conditions of circulation of the fluids in the exchangers.

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

The mixer/heat-exchanger CSE-XR was developed and patented by Fluitec AG. It is the most important invention in the static mixing technology of the last 20 years.
The CSE-XR is mainly used for temperature conditioning of highly viscous liquids at laminar flow. A strongly defined and well controlled homogeneity is guaranteed in any situation as well, as a very narrow residence time distribution. The reason for this excellent performance is its geometry, which is consequently based on the geometry of the most efficient static mixer type, the CES-X.
The very high radial mixing efficiency constantly ensures an intensive flow against the internal heat transferring tubes, thus allowing a
the compact design of this device.
Multitube heat exchangers are often not dedicated for scale-ups. Problems occur mainly in cooling processes at laminar flow conditions, when the product can "freeze" in particular tubes, due to its increased viscosity at lower temperatures. Uncontrolled residence time distribution and maldistribution are thereby leading to a bad process control.
Monotube heat exchangers (tubes with a double shell) can be built much smaller, if using static mixers. The mixing elements are improving the surface renewal rate significantly.
