An impact-resistant molded shell ensures an extended service life. Guns
features a 360-degree swivel connector to eliminate hose twisting.
Handguns use either a preset temperature sensor or an RTD (resistance
temperature detector) sensor. RTD sensing reduces temperature
fluctuations that affect flow and cause char formation. A wide operating
range of 65 to 230 _C (150 to 450 _F) provides additional application
versatility. RTD-style L4 guns have thermostats that are wired in series with
the heaters.
For handling very thick adhesive, the AD-31 LBS extrusion handgun
incorporates a large ball-and-seat and larger flow paths.
