Circulation Heaters

The new versaTHERM series of clean water and oil circulation heaters are designed to be more powerful and flexible than previously available 2.5-in. screw plug heaters. With field adjustable power levels between 0.5kW and 40kW, compact housings and multiple mounting arrangements, the series can be installed in a range of applications and equipment configurations. Twelve basic part numbers can be custom assembled for more than 120 different voltage, phase, wattage, and circuit combinations.

The model NWHSRG (water) and NWHOSR (oil) heaters can boost water or oil temperature anywhere in a distribution system or application. Design versatility allows field adjustment of power ratings with simple connections to the six heater elements. Additional features include:

•39 Water and 28 Oil kW and voltage ratings are field adjustable (NWHSRG: 0.5 to 40 kW; NWHOSR: 0.5 to 10 kW; 1 phase – 120, 208, 240 and 480V; 3 phase – 208, 240 & 480V)
•6-in. OD x 29-in. or 41-in. in length
•Multiple inlet connections (drain port can be used as an alternate inlet for more versatility)
•E1 general purpose terminal enclosure, rotatable 360° to match conduit connections
•INCOLOY sheath heating element welded to a 2.5-in. steel screw plug
•Cast iron body for oil applications, galvanized vessel for water applications
•Integral J type thermocouple for process loop or over-temperature control of the fluid
