E Series industrial
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.

Der Kältemittelkreislauf besteht im Wesentlichen aus Verdichter, luftgekühltem Verflüssiger, Expansionsventil und Verdampfer. Entsprechend den Prozessanforderungen werden auch Radialverflüssiger (zum Luftkanalanschluss), Splitverflüssiger (Außen-/Inneneinheit) und eine wassergekühlte Verflüssigerversion angeboten. Wir verwenden ausschließlich FCKW freies Kältemittel wie z. B. R134a und R407C. Alle Kältekomponenten sind von namhaften Markenherstellern und gewährleisten Zuverlässigkeit, Langlebigkeit und weltweite Verfügbarkeit. Der komplette Kältekreislauf ist auf die optimale und wirtschaftlichste Funktion des Industriekühlers ausgelegt und entspricht den neuesten Normen der CE-Richtlinie und der DIN EN 378, Teil 2.
Die komplette Elektrik ist auf die optimale Funktion des Industriekühlers ausgelegt und entspricht den neuesten Normen der CE-Richtlinie und der DIN EN 60204. Die exakte Temperaturregelung erfolgt bei allen Modellen der LT Baureihe durch einen mikroprozessorgesteuerten digitalen Temperaturregler. Alle LT Industriekühler sind für die Innenaufstellung geeignet und können optional auch außen aufgestellt werden.
Die Komponenten des Wasserkreislaufes bestehen standardmäßig aus nicht rostendem Material und komplett in das stabile Industriegehäuse eingebaut. Der Wassertank besteht aus hochstabilem und wasserneutralem Kunststoff mit Tankabdeckung (Option Edelstahltank). Die hydraulische Entkoppelung des Wasserkreislaufs vom Kältekreislauf sorgt für unendlich viele Einsatzgebiete in der Industrie. Der komplette Wasserkreislauf ist im Gerät montiert – mit einer Umwälzpumpe, Pumpenmanometer, Pumpenüberströmventil zum Pumpenschutz, kompletter Verrohrung sowie einer diffusionsdichten und hocheffizienten Isolierung. Der Wasserkreislauf (Verrohrung, Verdampfer und Pumpen) ist für einen definierten Volumenstrom und Druck ausgelegt. Für Sonderwünsche (höherer Druck und/oder mehr Volumenstrom) stehen unterschiedliche Pumpen zur Verfügung. Auch andere Umlaufmedien als Wasser (z. B. Öl) sind natürlich machbar. Ebenfalls umsetzbar ist die Ausführung als Durchlaufkühler (ohne Tank, ggf. ohne Pumpe).
