    immersion coolers

    Cooling capacity 1.7 kW to 115 kW

    Standard immersion / submerged recirculating chiller
    for suspension in an on-site tank

    The high-performance air- or water-cooled immersion chillers of the E Series not only increase productivity, but also reduce manufacturing costs. By means of an immersion cooler, the heat energy from production or process systems is removed from the system by an immersion cooler placed in the coolant tank.

    Immersion cooling units have an extremely high efficiency and ensure constant temperatures of the coolants.

    Individually configurable and expandable according to customer specifications.

    Circulating media

    Water     Emulsion      Oil

    Flow temperature range

    10 – 40 °C
