Product Overview
Watlow S01J1TRX-599 Strip Heaters – Unused NOS, Lot of Three
This is a lot of three Watlow S01J1TRX-599 metal-sheath strip heater elements designed for conductive surface heating in industrial equipment. Each heater is rated 500 watts at 240 volts and measures approximately 18 inches long by 1.5 inches wide.
Strip heaters like this are not generic heat sources. They are intended to be clamped or bolted directly to a flat metal surface so heat is transferred into a platen, tank wall, or fixture rather than dissipated into open air.
Product Condition
Unused, New Old Stock. The heaters show no signs of installation or electrical use and were kept in original packaging. Offered as a single lot of three matching elements.
Product Overview
Watlow strip heaters are widely used in long-service industrial systems where predictable heat transfer and mechanical durability matter more than compact form factor. The S01J1TRX-599 follows this pattern with a rectangular metal-sheath construction intended for rigid mounting and controlled operation.
At 500 W per element, these heaters are typically applied where moderate, distributed heat is needed across a defined surface area, assuming proper contact, grounding, and external temperature control.

Frequently Asked Questions
Can these strip heaters be operated in free air?
No. Strip heaters of this type are intended to be clamped or bolted to a metal surface that acts as a heat sink. Operating them without adequate heat transfer can cause overheating and premature failure.
Do these heaters include temperature control?
No. These are resistive heating elements only. Proper operation requires an external thermostat, controller, or other temperature-limiting device appropriate to the application.
What does the third stud terminal indicate?
The additional stud is consistent with a dedicated grounding connection, which is common on industrial metal-sheath heaters. Final wiring and grounding should follow applicable electrical codes.
Are detailed Watlow datasheets available for this exact suffix?
Watlow part numbers with suffixes like “-599” often represent custom or sales-order configurations. Only the ratings and dimensions stated on the unit itself should be considered verified.
This three-pack is best suited for facilities or builders maintaining equipment that already relies on Watlow-style strip heaters and needs correctly rated replacements with known physical dimensions.
