Oil-Air heat-exchangers

ACN and DCN Series Oil-Air Coolers. With alternate current drives (3 x 400V) and direct current drives (12/24V).
Constructed on a modular basis and are suitable for both static and mobile hydraulic systems. From size ACN-10 IEC standard motors are used allowing the coolers to be operated with special voltages.
On request the ACN oil-air cooler from size ACN-10 are also available with a declaration of conformity according ATEX 94/9/EG.

» Compact Oil-Air Cooler.
» High cooling capacity.
» High operating  pressure.
» Low pressure loss.
» Low noise level.
» Also available with declaration of conformity according 94/9/EG.

OCN Off-line Cooling Units. With Alternate Current Drives (3 x 400 V).
The OCN-Series is an extension of the ACN oil-air cooler line. Due to the integrated pump, the OCN offline cooling units may operate independent of the main flow of the hydraulic system. This ensures a continuous cooling of the hydraulic system and protects the cooler matrix against damage from pressure peaks. In addition the OCN offline cooling units can be mounted remote from the main system. The OCN off-line cooling units can be supplied with a filter and separate temperature switch on request.

MACN and AACN Cooling Units
New generation of MACN and AACN oil-coolers with reduced 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 fans, 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 two pass versions, thus covering oil cooling requirements for both low and high oil through flow volumes.

» Testing pressure: 25 bar static according to DIN 50104.
» Operating pressure: 16 bar (min. 2 Mill. Cycles from 0-16 bar at 2 Hz and 60°C).
» 2” SAE flange from MACN/AACN 70 upward.
» Compact oil-cooler.
» High cooling performance.
» Variable motor; DC / 12/24V.
» Low pressure loss.
» Max. operating temperature: 120 °C.
» Cooling of: Oil, HFA, HFB, HFC, HFD fluids up to v = 100 x 10-6 m2/s, water/glycol min. 65:35 mix – under no circumstances use water without corrosion prevention.

HCN oil-coolers
Reduced noise level. These coolers are ideally suited for mobile installations – for the cooling of hydraulic or lubricating oils. 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 two-pass versions, thus covering oil cooling requirements for both low and high oil through flow volumes.

Option
» Testing pressure 40 bar.
» Filter pad available on request.
» Thermo-bypass.
» Thermo-switch.
» Seawater version also available (off-shore).

JBJ Techniques is a specialist supplier of high-quality products for the mechanical power transmission and fluid power sectors. The company offers a high level of in-house expertise plus a huge selection of products to meet a very broad range of customer applications.

From specification, through technical advice and manufacture to after-sales support, JBJ Techniques provides a comprehensive and valued service to the power transmission and hydraulics industries. The company fields a UK-wide team of technical sales engineers to ensure that the business is close to its customers, and it enjoys excellent associations with European manufacturers, acting as sole UK distributor in many case.

JBJ’s team is recognised for its expertise in the selection and configuration of hydraulic and mechanical transmission systems. Able to draw on an extensive product range that provides the building blocks for bespoke systems both large and small, the in-house design team offers a complete service, ranging from an assessment of customer requirements to full technical backup, including engineering calculations, CAD-based system design, system build and certification. Moreover, customers can take advantage of JBJ’s own machine-shop facilities and skilled craftsmen to guarantee quality and control cost.

JBJ Techniques provides probably the widest range of couplings available within the UK with 14 different designs and 22 different styles of gear couplings alone. The product portfolio includes miniature couplings, all-steel gear couplings, flexible spider couplings, shaft couplings, torque limiting couplings, disc and grid type couplings, ATEX compliant and shaft locking devices.

However, as extensive as the selection is, couplings make up a fraction of JBJ’s portfolio. In addition, the company can provide gearboxes, clutches, pumps, hydraulic motors, flow meters, fluid power accessories — including cooling systems, reservoirs, seals and indicators — as well as a variety of bellhousings and flanges, to name just a few of the product categories.
