Compact Paint Stripping System Designed for Effective, Quick Removal

The Fastrip T2-120 Mix from Alit Technologies — a manufacturer of machines and products for the surface treatment of metals — is a more compact evolution of the T2 system and is designed for effective, rapid paint removal. Alit Technologies says the Fastrip T2-120 Mix offers an efficient, space-saving solution for companies that coat metal parts in-house.

“Alit Technologies has developed Fastrip T2-120 Mix based on its many years of experience in the paint stripping industry,” says Loris Rossi, Alit Technologies’ CEO. “This machine does not use ultrasound, as the mechanical action of the paint stripper on the parts is ensured by the hydrostatic thrust generated by the mixer.”

The fact that ultrasound has been replaced by a mixer is precisely what distinguishes Fastrip T2-120 Mix from the company’s model Fastrip T2-100. This makes the former a quieter machine that can also operate with a more polluted paint stripper. The absence of ultrasound also enables the use of electronic components that are less sensitive to the heat developed during normal machine operation. Overall, these choices have resulted in the design of an extremely robust, reliable, safe and well-functioning system.

With Fastrip T2-120 Mix, paint stripping is performed by immersing the workpieces in a tank containing a liquid paint stripping solution that is heated and kept under constant agitation through a special paddle mixer. At the end of the paint stripping cycle, the basket containing the parts is removed from the process tank. After a rinse, these can be reprocessed normally.

Fastrip T2-120 Mix is made entirely of AISI 304 stainless steel. It comes with a rectangular 450 × 700 × 300 mm paint stripping tank with a filling volume of about 120 L. It has a 1" stainless steel bottom valve for full emptying, a temperature sensor for the paint stripping fluid and a liquid level sensor. It is also equipped with a 2" upper sleeve for possible connection to a suction system.

There is also a steel mixer located on the short side of the tank which keeps the liquid constantly circulating for better stripping efficiency and better performance of the heating system. The coupling of the motor with the shaft is not direct, but it occurs through a belt-pulley transmission system which is designed to protect the motor against both direct heating by the liquid and vapors from the paint stripper.

Electric heating elements fixed on the tank’s exterior wall enable the maximum temperature of the paint-removing liquid to reach 80°C. Placing the electric heating elements externally avoids direct contact between the paint stripping liquid and the heating source, helping the product to meet the highest safety standards.

The Fastrip T2-120’s lids are made entirely of steel, complete with thermal insulation and two pistons to facilitate manual opening and closing operations. The lid’s closure is shaped in such a way as to collect the condensation formed on it during the paint stripping cycle. An electric lock stops the mixer if the lid is opened.

There is also an integrated control panel and external electromechanical switches for process parameter management. The panel is located below the tank and mounted on a mechanical slide that enables its removal for inspection or maintenance operations. These features enable the adjustment of liquid temperature and heating elements, and the control of the electric lock and mixer.

The tank has thermal insulation on all sides. Made of rock wool, it has a high insulation coefficient. There is also a side panel made of AISI 304 stainless steel, said to be easily removable for maintenance.
