Damage caused by open systems

Open cooling circuits can lead to contamination and germs. This can result in damage to the machine or system and loss of performance.

Install cooling circuits as closed systems

Notice

Motor damage due to electrolysis

Depending on the product, water coolers are made of different, sometimes corrosive metals (e.g. untreated aluminum).
Metals of different nobility can be electrically connected through contact with the coolant. In this case, there is a risk of electrolysis, in which the less noble metal can decompose in the circuit.

Refer to the product data sheet for the materials used that come in contact with the coolant.
Electrochemical processes occurring in the cooling system must be minimized by selecting suitable materials in the cooling circuit. Avoid a combination of different materials, such as aluminum, copper, brass, zinc, iron and halogen-containing plastics (e.g. hoses and seals made of PVC).
Connect all components in the cooling circuit (e.g. motor, chiller unit, pump, pipe system) with a potential equalization. This must be done with a copper rail or stranded copper wire with an appropriate conductor cross-section.
Coolant lines must not touch live parts. Ensure sufficient insulation and proper fixing of the cables.

Too little coolant and too slow coolant flow in the cooling circuit can cause the motor to overheat and reduce performance.

Recommendation: Flow rate monitoring and pressure monitoring are recommended in the cooling circuit

The cooling connections may only be sealed via the end faces of the water connections using suitable screw connections. Do not use conical screw connections or sealants in the thread (liquid sealant, Teflon tape, hemp, etc.) for sealing. The usable thread depth and the maximum tightening torque in aluminum must be taken into account.
The use of opaque hoses is recommended to prevent biological deposits.
The coolant supply must be interrupted if the motor is not used for a longer period of time.
