Report: D18-IR

The infusion tube has spray bores (Ø 1mm) in a V-formation at a 60° angle in a distance of 80mm. The D18CF-IR is developed specifically for hydrophobing agents and emulsions, which are introduced through a pressure pulse method. Through the pressure pulses, the borehole is only moistened - the material pulls itself into the wall. After an exposure further impetus is required to help increase the penetration of the agent. In this procedure no large quantities are compressed, so hollow and double-shell masonry can be rehabilitated too.

Different drill-diameters (up to Ø 3mm) for other applications are available on request.

The specified length of the packer is the distance from the large plate to the outlet openings at the top, corresponding to the wall thickness. Standard lengths are 250, 360, 450, 500, 650, 800 and 950mm - on request all intermediate lengths up to 1500mm are available.

The enlarged eighth plate (used with a setting mounting tool) helps to ensure that the packer is not seated too far into the wall, so the clutch is always reachable.

Our single use injectors negate the need for cleaning or removal like traditional steel packers. After application, the packer remains in the wall and can be cut off flush to the wall. The free-running ball valve ensures a secure closure, provided a backpressure of at least 3 bars is present. In low-pressure applications (less than 3 bars), the ball-closure may not close in this case, caps are available (Kappe/C).

Our products can be used in construction projects great and small. Used correctly they are the best injectors available on the market and are the first choice of construction experts. We do not make any claims as to the maximum back-pressure our products can withstand. You, as construction professionals can judge the conditions present in your own projects and use our products accordingly.

To avoid damage of the quick-coupling clutch and to set the Packer correctly in the borehole, it is necessary to use the setting tool (ESH/C).
