Product catalog summary

Background
Traditional fan drives are inefficient as they operate at engine speed, leading to excess fuel consumption, noise, energy use, and emissions.

Hydrostatic Fan Drive Systems
These systems, designed by Haldex, include a hydraulic pump, motor, and cooling unit, allowing fan speed to be controlled independently of engine speed for precise cooling.

Key Features

Fail Safe: Automatically maximizes cooling power during system failure to prevent engine damage.
Flexibility: Allows remote placement from the engine, optimizing airflow and reducing noise.
Correct Speed: Smooths fan speed changes to avoid mechanical shock loads.
Temperature Control: Maintains precise temperatures for engine and hydraulic fluid, enhancing efficiency.

Example
Independent fan speed control reduces power consumption, as a fan running at 1000 rpm requires 2 kW, but at 2000 rpm, it needs 8 kW.

Optional Features

Electronic Control Unit with three input signals for various cooling needs.
Complete systems with options like AC-valve, reversible fan direction, and pressure gauges.

Motors and Pumps

Motors: W-series motors with displacement range 3-50 cc/rev and pressure up to 276 bar.
Pumps: W-series pumps with similar specifications and optional valve features.

Power Packs

Various series with different voltage ranges, pump displacements, and maximum pressures.
Reservoirs available in plastic and steel with varying capacities.

Hydrostatic Fan Drive Systems: In a traditional fan drive the fan is linked to the engine through a belt drive or mounted to the crank shaft. This means that the fan will run at a speed determined by the engine and not determined by the required cooling power. In an electric on/off installation it will either run at full speed when above the cut-in temperature limit or stall when below the cut-off temperature. These systems will cool the engine in quite a wide temperature range, in some cases even ”more than needed” at the cost of fuel, noise, energy and emission. Hydrostatic fan drive systems...
