Heating Liquids/In-Tank

There is a definite benefit to being able to heat a liquid in an open tank. Jacoby-Tarbox jet pump in-tank heaters optimize and streamline the operation by completing two jobs at the same time -- both heating and circulating the mixture. Installed submerged in the tank, open tank heaters are especially suited for cooking, heating & circulating liquids and they maximize the condensation of steam into operating liquids to provide fluid heating. Model NWH is an inexpensive basic heater. Jacoby-Tarbox models are more versatile and produce strong mixing during the heating process. Model XL-32 provides the highest steam flow for a given pipe size, as well as providing near noiseless operation with a little as 3 psig of steam pressure.  NWH and XL-32 produce temperature rise of up to 120° F (49° C) with a final tank temperature of 160° F (71° C). Model RJ (Ring Jet) Heater operates at steam pressures from 5 to 150 psig (1035 kPag) above the submergence (head pressure), achieving final tank temperatures up to 179° F (82° C).

Because Jacoby-Tarboxy jet heaters operate on a simple heat transfer principle, they are efficient and cost-effective. In-tank jet heaters are particularly well-suited for these applications: continuous heating, cooking grain, direct contact heat transfer, cooking mash, cooking starch and homogeneous liquid/temperature distribution throughout a tank. By using imaginative engineering, uses for these units is virtually endless!
