TJ 20G Retractable system
The TJ 20G Retractable System features a retractable version of the TJ 20G rotary jet head. The TJ 20G provides a 3600 indexed impact cleaning over a defined time period.
Processing, storage and mixing tanks and vessels between 15 and 150 mm3; (4,000 to 40,000 US gallons). The TJ 20G Retractable System is designed for use in tanks where internai structures complicate the correct positioning of a T J 20G on a fixed downpipe. The TJ 20G Retractable System can replace the portable installation of TJ 20G.
The T J 20G Retractable System extends from the pressure of the cleaning media. When the pressure of the cleaning media is shut off, the media is drained through the T J 20G nozzles and the return spring retracts the T J 20G to its initial position. The T J 20G Retractable System is equipped with magnetic positioning sensors indicating the position of the T J 20G in either retracted or extended position.
Tool for maintenance
A special tool is required to disassemble and reassemble the TJ 20G and the circlips.
The T J 20G Retractable System is available in three stroke lengths:
- Stroke length 600 mm
- Stroke length 1,000 mm
- Stroke length 1,500 mm
The TJ 20G Retractable System is supplied with a standard size house welding connection for mounting on the tank. The tank and inlet connection s are available in various options. An electronic rotation sensor to verify 360° coverage can also be included.
Please specify the stroke length, the intet and tank connection options required. For technical specifications of the TJ 20G, a data sheet is available upon request.
