Heating Liquids In-Tank

Heating Liquids/In-Tank
Models NWH, CTE, XL-32, RJ

There is a definite benefit to being able to heat a liquid in an open tank. Penberthy 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. Model CTE is more versatile and produces 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. The CTE, 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 Penberthy 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!
