PSG Heated Wall Bushings: Verwarmde wanddoorvoeren

PSG heated wall bushings: heated wall feedthrough for gas analysis

PSG heated wall bushings are developed for gas analysis installations where heated sample lines are routed through walls. A typical application is routing heated sample lines through masonry to an analysis room, or leading heated lines out of climate chambers in the automotive industry.

Application

The wall feedthrough is used where the sample line passes through a wall and the gas temperature threatens to drop below the dew point or acid dew point. Heating the full tube length homogeneously completely eliminates cold zones. This prevents condensate formation, blockage and washout of water-soluble gas components such as SO₂. The feedthrough is also suitable for several lines of different dimensions in one housing.

Technology

The wall feedthrough has a robust outer jacket of SS316Ti stainless steel, corrosion-resistant and intended for installation in masonry. Inside is an insulated stainless steel tube with heating cable that reaches the required temperature. Heating is uniform over the full length, without cold zones. The outer surface temperature remains below 60 °C for safe use. Swagelok fittings are used as the standard connection; other connections are possible on request. The length of the connection cable and the type of connection plug are produced to order.

Functions and options

The wall feedthrough is available in controlled and uncontrolled versions. Holding temperatures of 90 °C and 200 °C are available as standard; other temperatures on request. The length is matched to the wall thickness. Several lines of different dimensions can be combined in one housing. Individual custom solutions are standard.
