Side view of Flip Flow Screens

In order to fill the gap in its product basket and the business opportunities existing in the market for flip flow screens, TRF along with its’ subsidiary company, Hewett Robins International Limited, UK, has developed its first flip flow screen.

The Applied Research & Development department of TRF which collaborated with HRIL’s engineers over this project has successfully developed a single-deck flip flow screen. The team working on this project is confident of its capabilities to develop variants of flip flow screens, in future. Mr. Ashish Banerjee, Chief, Design, Engineering and Technology, is of the view that, “We first need to establish one model in the market and then we can go for more variants.”

The Hewitt Robins engineering team believes that the world–class engineering and manufacturing facilities of TRF coupled with their strength in flip flow screen application and marketing will undoubtedly position the two companies as leading manufacturers of flip flow screens.
