PRIMARY PRODUCT
Industrial Heat Exchangers
Heat transfer is our core commercial offering: equipment for heating, cooling, condensation and heat recovery, manufactured in Vadodara from your process data, drawing or EPC specification.
Heating
Process heaters using steam, hot oil, or a hotter process stream.
Cooling
Product, recycle, and utility coolers using cooling water or another process fluid.
Condensation
Overhead and process condensers where vapour must be condensed against a coolant.
Heat recovery
Feed/effluent and interchangers that recover heat that would otherwise be rejected.
Evaporation / reboil
Kettle reboilers and vaporising duties where the process specifies hold-up and disengagement.
Configurations
Matched to your process duty
Shell-and-tube, U-tube, rectangular box type and double-pipe — each selected for thermal expansion, cleaning access and the service your plant requires.
