Shell and tube type heat exchangers

NewCool products are the result of many years of experience combined with a wealth of knowledge from within the field of fluid and transmission engineering. Thanks to the standardisation of individual components, technically sophisticated solutions are available at a highly competitive price/performance ratio. The standard BNZ series offers four shell sizes with available lengths of up to 2100 mm. We also offer tailor made solutions for the most arduous applications and according to customer specification. BNZ coolers are suitable for all industrial and marine environments.

The BAMNZ is a series of compact heat exchangers with a fixed tube bundle, which has been standardised into logically grouped models with a heat-exchange surface of from 0.43 to 40 m2. The models comprise basic units, each divided into two versions (narrow/wide baffle spacing), each also available as a 1-pass version, 2-pass or 4-pass version.

The new oil/water safety heat exchanger BAMNZSC which, by means of a double tube, prevents the danger of mixing the cooling and the to be cooled medium. The space between the two tubes is filled with a sealing liquid. A pre-charged diaphragm accumulator compensates the thermal change in volume of the sealing liquid and keeps the sealing liquid pressure almost constant. Any leaks in the bank of tubes are indicated at once by the pressure switches. These two characteristics, the pre-charging of the system in connection with the min. and max. pressure monitoring, guarantee an independent operating pressure for the cooling medium as well as the liquid to be cooled. A special liquid enables optimum heat transfer. It is frost-resistant up to -30°C and, at the same time, safe with foodstuffs. Other liquids available on request.

The following data will be required to correctly specify cooling components for your application: oil inlet temperature, oil volume, oil specification, volume of water, water inlet temperature, cooling performance.

At jbj Techniques our technical staff will be happy to assist in the selection upon receipt of the required information. Compact design, robust construction, extremely low pressure drop, high quality materials and ease of maintenance are the prominent features of the NewCool shell & tube coolers.

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.

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.
