Tank Heating Eductors
Stocked in sizes ⅜″ up to 3″ in Carbon Steel and 316LSS
Overview
There are many advantages to using Tank Heating Eductors for heating liquids in open vessels. The tank eductor heater provides direct contact of the steam into the liquid, assuring complete transfer of the energy in the steam into the liquid being heated.
Other types of heating lose efficiency as the interior of the heat exchanger builds up scale. With eductors, the velocity of the steam being injected into the vessel also causes the liquid contents to be agitated while heating occurs — without the need for other types of mixers. This provides more even heating of the vessel contents and permits the steam to be dispersed over more of the liquid volume, resulting in more homogenous heating than with other methods.
These designs allow steam to be used from 10 to 140 PSIG for heating. Because of the nature of direct steam injection, heating vessels at atmospheric pressure beyond 140°F should not be attempted — exceeding this temperature could result in uncondensed steam evolving from the liquid.
