ATEX Retractor System TANKO-RT/-RTS
3 Design and Function Translation - Operating/installation instructions 2020/01 29/121
Power cylinder and locking cylinder form the pneumatic part.
The compressed air supply to the power cylinder is via two throttle check valves. These are attached to
the outside of the power cylinder.
The locking cylinder is supplied with compressed air using a plug-in connection, which is located on the
end of the locking cylinder.
At the connection point between the pneumatic pipe / hydraulic pipe, there is a 2 ½" clamp connection
to connect the two parts of the device.
The hydraulic section consists of the hydraulic pipe with process connection [PC] and media
connection [MC]. The hydraulic pipe contains the centering adapter for holding the spray head and
supplying the cleaning medium.
A clamp connection that enables the device to be connected to the media supply line is located on the
hydraulic pipe of the device.
On the hydraulic pipe for mounting the spray head, there is a process connection [PC] that enables the
device to be fastened to the intended container. The process connection [PC] is available in different
variants (see
Table 3.3-6: Connection Variants )
The connection of the piston rod to the centering adapter is implemented with a threaded connection.
There are 5 variants of the spray head, type A, B, C, D and S. Types A, B, C and D are rotating spray
heads and differ in the width of the spray slit and therefore in use. The spray angle of types A to D is
270° in the direction of the retractor system. Type S is a static spray head which, that is suitable for use
in combination with the TANKO-RTS retractor system a targeted area of a specific area in the container.
Due to the shape of the head and the closing function of the retractor system, the area in front of the
spray head is not sprayed with cleaning agent.
Static Spray Head
The static spray head is shown in Figure
3.1-2
as a blank without spray or drain holes. The number,
position, alignment and diameter of the holes are to be specified by the user according to requirements.
The number and diameter must be specified in such a way that the maximum flow rate of 10 m³/h is
not exceeded at the maximum medium pressure of 6 bar (87 psi g).
