A Legacy of
Thermal Innovation
Engineering sustainable water, energy, and waste recovery systems for industrial applications.
Two Decades in Thermal Engineering
Vapour Desal Technologies has been at the forefront of thermal desalination and waste-to-energy engineering for nearly two decades. Established in 2005 as a joint venture between Dr. Marco Rognoni of Saline Water Specialists (Italy) and Mr. M.P. Ramaswamy of GB Engineering (India), the company was founded to bring advanced desalination technology into the Indian industrial ecosystem.What began with thermal deaerators and early desalination projects has evolved into a multi-domain engineering practice.
