Water Cooled Reactors

Product catalog summary

General Information
Water cooled reactors are designed for continuous duty at nominal current with a design lifetime of 20 years. They feature a 3-phase inductor electrical connection and an open frame design with IP 00 protection class. The cooling type is liquid-based.

Mechanical Specifications
The maximum dimensions are 1000 x 1000 x 1000 mm, and the weight is less than 1000 kg. The reactors comply with vibration standards EN50178 and EN60068-2-6, and impact standards EN50178 and EN60068-2-27.

Connections
Electrical connections are made using copper/aluminium busbars, with a protective earth connector ranging from M8 to M12. Liquid cooling connections are specified by the customer, and temperature sensors are connected via a terminal block.

Electrical Specifications
The nominal voltage between phases is up to 1500 Vac, with a nominal current of up to 3000A. The continuous thermal current is 3000A, and the fundamental frequency is typically 50-60 Hz. The du/dt voltage is a maximum of 3000V/us. Inverter switching frequency ranges from 1.5-4.0 kHz with laminated steel and 5-10 kHz with amorphous steel. The isolation test voltage is 2500 Vac for 60 seconds, and insulation resistance is greater than 2 MΩ. The temperature class of the insulation is Class H (180 °C), and the electrical insulation system is UL recognized.

Liquid Cooling System
The cooling liquid is an ethylene glycol/water mixture, with a recommended ratio of 30/70%. The temperature range for the cooling liquid is -40 to +55 °C, with a nominal temperature of +50 °C. The maximum temperature of the cooling liquid (out) is +90 °C. The nominal liquid flow is a maximum of 10 dm3/min, with a maximum required flow of 15 dm3/min. The system is designed to dissipate a minimum of 70% heat to the liquid at 40 °C ambient temperature.

Ambient Operating Conditions
The ambient temperature range for operation is 5 to +65 °C, and for storage, it is -40 to +80 °C. Air humidity during operation is 5 to 96%, and in storage, it is 5 to 99%. The ambient air pressure ranges from 930 to 1065 mbar, and the maximum height from sea level is 1500 m. Maximum heat dissipation to air is 30% at 40 °C ambient temperature.
