Air Heaters

Air and gas temperatures up to 1000°F (540°C). Units are fitted with a tubing “T” for convenient power lead outlet, while larger diameters can be supplied with post terminals on the sheath for direct electrical connections. NPT threaded fittings, hose adaptors, flanges, or custom fittings are available for easy installation. Applications include: Heat staking, Shrink Fitting, Plastic Welding, Drying, Laminating, Sealing, Packaging, Preheating, Soldering

Starflow Circulation Heaters

STARFLOW circulation heaters are designed to improve process time and operating efficiency during the semiconductor manufacturing process. By using clean, hot gases, the STARFLOW circulation heaters reduce wafer drying time while flameless dry heat efficiently solders and desolders electronic circuits and boards.


Versaline Circulation Heaters

VERSALINE 500 is Watlow’s new value-added chamber assembly for in-line heating applications. This heating package is ideal for situations where a high watt density circulation heater is required but space is limited. All the necessary components, including a FIREROD® heater, inlet/outlet lines, thermocouple and tubing, are presented in a compact package.
