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.

Cooling solution for internal combustion engines

For machine manufacturers requiring improved performance or combined cooling of multiple media in a compact design or different cooler shape.
‍
Following an accurate design, verification and operational validation of the prototype directly on the engine, we develop a complete product for cooling the water / intercooler / oil with side by side or overlapping masses.
The complete package can have the configurations chosen by the customer and can include, in addition to the heat exchanger, the fan suitable for the application and relative protections, supports and brackets for connection to the motor, aluminum, stainless steel or rubber pipes, aluminum expansion tanks, integrated or independent.
‍
Analysis of engine data sheet and customer cooling and sizing requirements, followed by design of cooling system.

CAD drawings produced to enable full component set up including all parts in 3D model.

Further analysis of component package.
‍
Either the engine is supplied by the customer for full build up of package to the engine or components supplied to customer to build the package.

Bespoke design and build to fulfill customers application needs.
There are existing design packages for Cummins, Perkins, Volvo, Caterpillar, Kubota, Hatz, Yanmar, Doosan, Fpt, VM, Kohler and Deutz.
