Oil/air heat exchangers
type LKI
Low noise level
High performance
Low cost
Product description
With this new generation of Universal Hydraulik LKI oil-coolers, the manufacturers have succeeded in reducing the noise level. These coolers are ideally suited for stationary installations - for the cooling of hydraulic or lubricating oils. The range has been extended to include slow-running ventilators, and the housings have been optimised, in order to produce the very low noise level. In order to make the cooler range as comprehensive as possible, the smaller models are also available as single or dual versions, thus covering oil-cooling requirements for both low and high oil throughflow volumes.

AIR-OIL HEAT EXCHANGERS -SERIES AP WITH HYDRAULIC MOTOR :
This type of exchanger has been designed for use on movable machines where battery feed is insufficient or when exchangers with direct current supply are inadequate to produce high thermic yields. The radiative unit is of aluminium because this material is a very good conductor; providing high thermic yields and relatively compact over-all dimensions. Thanks to the particular construction of the radiative unit the exchangers of the series APL cope well with water hammer conditions which, at peak values, must not exceed the minimum allowable dynamic pressure of 20 bar. The maximum allowable static pressure is of 35 bar.

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.

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
