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.

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.

HYDAC bladder accumulators consist of a welded or forged pressure vessel, an accumulator bladder and valves at the gas and the fluid connection.
In addition to the standard construction, special constructions are possible, especially for applications for very high flow rates (e.g. up to 100 l/s) or pressures (e.g. up to 1,000 bar).
The technical specifications are:
- Nominal volume: 0.5 ... 450 l,
- Max. working pressure: up to 1,000 bar,
- Available elastomers as standard: NBR, ECO, IIR, FKM (FPM),
- Accumulator shell materials: carbon steel, stainless steel, aluminium.
The following advantages set HYDAC bladder accumulators apart:
- high flow rates possible,
- no pressure differential between fluid side and gas side,
- compact, low maintenance,
- high cyclic frequencies.

energy, silence, comfort, service life…
energy storage
A hydro-pneumatic accumulator is a vessel which, in hydraulic circuits, is capable of storing a large amount of energy in a small volume.
a simple principle
If the very low compressibility of fluids makes it difficult to store their energy in small volumes, it does, however, enable them to transfer a significant force. Gas on the other hand is highly compressible, and can therefore store considerable amounts of energy in small volumes.
The hydropneumatic accumulator makes use of these two properties.
