With this new generation of Universal Hydraulik LKI oil-coolers, noise level has been reduced. These coolers are ideally suited for mobile installations – for the cooling of hydraulic or lubricating oils. The housings have been optimized, in order to produce the very low noise level and 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 through-flow volumes.
Product Features
Testing pressure: 363 psi (25 bar) static according to DIN 50104
Operating pressure: 232 psi (16 bar) (min. 2 Mill. Cycles from 0-232 psi (0-16 bar) at 2 Hz and 140 °F (60 °C))
Bare tube heat exchangers are an ideal choice for cooling high viscosity fluids and particle containing fluids that may clog a cooler with internal cooling fins.
Fail-safe coolers prevent the mixture of fluids should one of the cooling tubes fail. This is achieved by double wall tubes and safety switches that indicate a tube failure.
Hybrid heat exchangers combine the advantages of shell & tube and plate heat exchangers. The larger surface area permits a physically smaller heat exchanger with better cooling capacity.

The Fail-Safe Safety Heat Exchanger from Universal Hydraulik is satisfying the highest quality demands for decades. Since then, it is avoiding application errors and the unintended mixing of two fluids.
The SCM/FS failsafe series is based on the successful SCM series of hybrid coolers. This brings all the benefits of the high-efficiency hybrid coolers to the failsafe series. A further enhancement of this series is that no accumulator is required. Leakage is monitored 100% by an electronic sensor which sends out a signal should leakage occur in either the inner or outer tube.
The 100% electronic monitoring is suitable for all Industry 4.0 applications. Safety Heat Exchanger is used for applications where an error could lead to serious consequences.
