A Legacy of Thermal Innovation
Engineering sustainable water, energy, and waste recovery systems for industrial applications.
Our Story
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 specializing in:
- Thermal desalination systems (solar, nuclear, and waste-heat-driven)
- Vacuum Vapour Generators (VVG) — a proprietary heat-recovery interface
- Process optimisation for tyre pyrolysis and waste-to-energy systems
- Custom pressure vessels and mechanical engineering systems
Our Journey
Founded as a JV between SWS (Italy) & GB Engineering (India)
First project: 50 m³/day Low Temperature Flash for NIOT, Chennai
First solar thermal desalination plant at Narippaiyur (RAMDAS)
Nuclear desalination plant delivered for BARC, Mumbai
NTPC Simhadri plant using flue gas heat recovery
DST-funded mini solar desalination plant with IIT-Madras at Kanyakumari
3 LTTD plants commissioned in Lakshadweep Islands
Rebranded as Vapour Desal Technologies
OSCOM IREL project: 2 × 250 m³/day MED-TVC
Expanded into waste-to-energy through tyre pyrolysis engineering
Developing sustainable engineering solutions for water, energy, and resource recovery
