To help break up and resuspend the solids, it helps to have heat as well as a diluent. A typical temperature might be 140°F (60 °C), but depends on the flash point of the diluent. The diluent might be the product itself, or could be a compatible cutter stock such as diesel, VGO, LCO, etc.
Absolutely! We believe the real value of the Twister is unlocked when Twisters are permanently installed on a tank, allowing “Online Tank Cleaning"...allowing the tank to remain in service….and not just a conventional offline tank cleaning. The Twister is a unique technology that provides a proactive ability to manage the sludge problem, with the tank
A specific pump recommendation can be made for your application. In general, a self-priming high head centrifugal pump from 6” x 4” up to 10” x 8”, powered by 400 – 550 HP, and capable of 1000-2200 gpm (227-500 m3/hr) at 150 psi (10 bar) is adequate.
Again, it depends on the product, sludge level, heat, chemistry, and diluents, but often 48 hours of circulation is adequate to refluidize the solids.
Twisters have been built on manway covers as small as 20”, and as large as 36”.
The number of Twisters needed depends on the tank size and contents. A small tank (
