Water Cooling
Devices with cooling water tubes
The form of connection to the cooling unit depends on the conditions in the overall sys-
tem. One possibility is to use cutting rings with suitable fittings. The following companies,
for example, provide the connection elements:
▶ EMB – Eifeler Maschinenbau GmbH: http://www.emb-eifel.de/
▶ RO-FI Edelstahlhandel GmbH: http://www.rofi.de
Devices with threads
The device comes with a connection area with internal screw threads at the bottom. The
form of connection to the cooling unit depends on the conditions in the overall system.
One possibility is to use straight compression fittings.

Use cooling water free of additives with negative effects on the cooling behavior. We recommend distilled water with an-
tifouling additives.
If you use a different coolant, the power must be reduced according to the manufacturer's instructions.

Cu = copper, stainless steel tubes are available on request. Note: The use of stainless steel tubes reduces the cooling ef-
fect and the efficiency of the device. For detailed information contact SIEB & MEYER.

100 % rated current up to a water temperature of 30 °C. At a water temperature between 30 °C to 60 °C the power must be
reduced by 1.5 % per 1 °C.
Characteristic curves: pressure loss to volume flow rate
The following diagrams shows the relation between pressure loss (Δp) and volume flow
rate (Q) when water is used as coolant. The characteristic curves apply to a water tem-
perature of 30 °C.
