Product Range
Our Featured Products
Industry-proven heat exchangers and pressure vessels engineered for performance and longevity.
Shell and Tube Heat Exchanger
A Shell and Tube Heat Exchanger transfers heat between fluids using a series of tubes enclosed in a shell, ideal for high-pressure systems.
Plate Heat Exchanger
A Plate Type Heat Exchanger uses thin metal plates to efficiently transfer heat between fluids, offering compact design and high thermal performance.
Air Cooled condenser
An Air Cooled Condenser condenses refrigerant vapors using ambient air, offering efficient, water-free heat rejection
Air Fin Cooler
An Air Fin Cooler transfers heat from process fluids through finned tubes using ambient air, ensuring efficient and water-free cooling.
Double Pipe Heat Exchanger
A Double Pipe Heat Exchanger transfers heat between two fluids using concentric pipes, ideal for low flow and high-temperature control.
Marine Heat Exchanger
A Marine Heat Exchanger cools engine systems by transferring heat from coolant to seawater, ensuring efficient marine engine operation.
Fin fan cooler
A Fin Fan Cooler uses fans to blow air over finned tubes, efficiently cooling process fluids without water, ideal for industrial applications.
Filter Vessels
A Filter Vessel removes impurities from liquids or gases, ensuring clean flow and protecting equipment in industrial systems.
Hairpin Heat Exchanger
A Hairpin Heat Exchanger enables efficient heat transfer in compact spaces, ideal for high-pressure, two-phase flow applications.
Kettle Reboiler Heat Exchanger
A Kettle Reboiler Heat Exchanger uses boiling liquid to generate vapor, often in distillation columns, ensuring efficient heat transfer and process control.
Removable Tube Sheet Heat Exchanger
A Removable Tube Sheet Heat Exchanger has a tube bundle that can be taken out from the shell for easy cleaning and maintenance, making it ideal for fluids that cause fouling or scaling.
Air Preheater
An Air Preheater recovers waste heat from flue gases to preheat incoming air, boosting boiler efficiency and saving energy
Dump Condenser
A Dump Condenser efficiently cools steam or vapor by transferring heat to a cooling medium, often used in industrial processes.
Surface Condenser
A Surface Condenser cools steam by transferring heat to a cooling medium, commonly used in power plants to condense exhaust steam.
Brass Tube Bundle Heat Exchanger
A Brass Tube Bundle Heat Exchanger transfers heat efficiently using brass tubes, offering excellent corrosion resistance and durability.
Fixed Tube Sheet Heat Exchanger
A Fixed Tube Sheet Heat Exchanger is a shell-and-tube exchanger where both tube sheets are permanently welded to the shell, and the tube bundle cannot be removed. One fluid flows inside the tubes while the other flows over the tubes within the shell, enabling efficient heat transfer.
U Tube Heat Exchanger
A U Tube Heat Exchanger transfers heat using U-shaped tubes, ideal for high-pressure, and thermal expansion.
O2 Reactor and Blow Tank
O2 Reactor and Blow Tank enable efficient oxidation and flow in compact industrial systems.
