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.

AC Industrial Coolers (LAC) - Coolers with AC motors for industrial hydraulic systems
The LAC air oil cooler with single-phase or three-phase AC motor is adapted for use in the industrial sector.Together with a wide range of accessories, the LAC cooler is suitable for installation in most applications and environments. The maximum cooling capacity is 160 kW at ETD 40°C. Choosing the right cooler requires precise system dimensioning. The most reliable way to dimension is with the aid of Oiltech’s calculation program. This program, together with precise evaluations from our experienced, skilled engineers, gives you the opportunity for more cooling per pound invested.

The first choice for oil cooling in hydraulic circuits.
Your Advantage
The correct cooling solution offers a longer oil life, i.e. lower maintenance and change frequency. A constant oil temperature also means improved machine precision.
AKG-Range T1 - T 11... maximum working pressure 26 bar

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.

Airtech Aluminum Fan Cooled Units
Our line of Airtech Fan Cooled Heat Exchangers provides a standardized, reliable and self-contained solution for remote cooling requirements in both the Industrial and Mobile Vehicle markets. These compact, high efficiency Oil Coolers and Aftercoolers can be the perfect answer for applications where cooling requirements are remotely located, cooling water is unavailable or impractical, or where coolants may be subject to freezing.
These pre-engineered packages include an all-aluminum vacuum brazed bar & plate heat exchanger for superior durability and performance in a cost-effective, compact, light weight construction. Motors can be supplied in either 60 hertz or 50 hertz AC versions, or 12 volt DC versions. Both come complete with finger guard and shroud.
Our product range encompasses 11 different model sizes. The first 8 sizes are vertical mounts with horizontal air flow, while the three largest sizes are horizontal mounts with vertical air flow. The units come with a variety of standard options, ensuring our customer gets what they need with very short lead-times.

The Company ESK is building oil separators for refrigeration systems working with synthetical refrigerants like R22, R404a, R410a, and as well for many natural refrigerants like CO2, ammonia and hydrocarbons.
The ESK standard oil separators type OS effectively remove oil from the discharge gas in the strainer elements and return the oil through a high precision float valve to the crankcase or oil control system. The efficiency of oil recovery is dependent on the reduction of gas velocity in the separator itself. Providing the oil separator is correctly applied, this will be about 95 % to 98 %.
Beside conventional separators ESK is also offering high performance oil separators type BOS with a separation ratio of more than 99%. The BOS oil separators are equipped with coalescence elements made of glass fiber micro for the efficient separation of aerosol particles out of the discharge flow.
The use of ESK oil separators protects the compressor from defects cause by lack from lubrication and improves the heat transfer in the evaporator.
Oil separators should be installed whenever the following applications are considered:
• Evap. temp. below <-10 °C
• Blast freezers
• Capacity control
• Two stage plants
• Parallel systems
• Cascade plant
• Flooded systems
• Booster

The Parker oil separator removes oil from system refrigerant by means of a highly efficient coalescing filter. The filter is 98.5% efficient, filtering oil and particles down to 1/10 of a micron while leaving a trace amount of oil necessary for adequate system lubrication. The separator is ideal for recovery and reclaim operations.
