jbj Techniques Ltd in partnership with IRA Engineering are pleased to announce an exciting new addition to their product portfolio. This new addition being the IRA Engineering, Italian manufactured, range of air blast coolers. The range of air blast coolers is extensive, consisting of the RAL, aluminium, series of inline coolers, having a heat dissipation range of 1.6 kW to 200 kW (based on a ∆T of 40°C) and an oil flow capacity of 5 to 800 lpm. All standard AC and DC motor voltages are available for the fan drive, as well as AC motors to ATEX certification. In addition, hydraulic fan drives are available as standard fixed speed or as a proportional motor drive system, enabling you to tune the fan speed to the heat dissipation requirement. In addition to the RAL series is the GA series of offline (autonomous) coolers, the RO copper and steel air blast coolers and the RS series suitable for closed loop hydraulic systems.

Coolers are available to ATEX certification, marine specification C5M and of stainless steel manufacture. IRA Engineering in conjunction with jbj Techniques Ltd, have the ability to design and manufacture bespoke cooling to suit your specific applications. Taking your cooling concept from design to completion. A most recent example of this being a battery cooling system for electric vehicles. In addition, and in this application, the electric cooling fan motor fitted to the air blast cooler can have CAN bus integration ability, enabling the speed of the fan to be tuned to the required heat dissipation from the air blast cooler, saving power and extending the vehicle range. For those of you wanting a complete engine cooling solution, taking into account engine water cooling, oil cooling and intercooler cooling, details provided on request.

External gear motors for fan drives

This fan drive motor is a range for vehicle cooling systems. These types of motors are widely used in modern hydraulics thanks to their performance, long service life and low maintenance costs.
‍
An electro-hydraulic fan drive offers significant advantages if compared with traditional solutions with electric or belt drives. Maximum performance is achieved by combining the fan drive system with a fully-programmable electronic control unit.
‍
The fan drive system consists of:
» Reverisible fixed displacement hydraulic gear motor.

Fan-drive-operated manifold which consists of:
» Special NG6 directional valve for smooth controlled rotation change.
‍
» Non-return valve to avoid cavitation during reversing.
‍
» Proportional valve – which allows rotational changes by over riding the settings. The valve is actuated by an signal from an electronic circuit board designed for the “fan drive” function. It controls the rotation speed of the hydraulic motor by means of on-board sensors.
‍
» Circuit relief valve to control the operating pressure of the hydraulic motor.
‍
» Motor displacement: Group 2 from 4 to 31.5 cm³/rev. (from 0.24 to 1.92 in³/rev).
‍
» Maximum pressure: up to 250 bar (3600 psi).
‍
» Speed rotation: up to 4000 rpm.
‍
» NG6 solenoid operated directional valve allows the reversing functiuon: technical data flow max 80 l/min, P max 350 bar.
‍
» Coil data: 12 or 24 dc with plug DEUTSCH DT04-2P for male connector type DEUTSCH DT06-2S.
‍
» Pressure control valve: Q max 120 l/min, P max 210 bar.
‍
» Proportional pressure control: Q max 80 l/min, P max 250 bar.

In a fan drive system, the electronic circuit board controls the rotation speed of the hydraulic motor based on the actual heat dissipation through the cooling system. The signals from the temperature sensors or CAN network are processed by the electronic card which, depending on its settings, controls the rotational speed of the hydraulic motor proportionally and cleans the cooler matrix by automatically reversing the direction of rotation of the motor. The software developed and designed for the fan drive function improves the vehicle fuel economy in compliance with eco-sustainability regulations. Resulting in advantages for both the client and the community. The electronic card is plug and play and reduces the vehicle start-up time and costs.
