Custom Tailored Solutions
We optimize thermal design, engineering and manufacturing to custom – tailored solutions.
Vast experience with almost all standards around the world.
Experience throughout the decades combined with our new technical ideas
and a fast moving organization.
Equipment and Systems
Static equipment aimed at increasing efficiency of burners by heating inlet air recovering heat from exhaust flue gas outlet before release it to the stack.
Our proprietary technology based on dimpled plates optimizes heat transfer and minimize risk of fouling, gas stagnation and acid corrosion.
APH in fact is at the cold tail of gas path, so it may “filter” dust, fouling and debris. collected by gas during its way.
Temperature Up to 425 °C
Temperature Up to 700 °C
High temperature applications
Weather Resistance Steel – Corten type
Risk of acid & water dew point
Steam Air PreHeater (SAPH) is an ancillary equipment installed where air temperature is low, to reduce the risk of acid corrosion of APH cold bank.
Temperature Up to 400 °C
Temperature above 800 °C
Honey Comb / Staggered Structures
When there is formation of unburnt fuels (soot) during combustion, cleaning is mandatory to reduce deposits on the heat transferring surfaces which causes reduction of efficiency and risk of burning.
Working at regular time intervals, installed between heat transfer surfaces & inject pressurized fluid.
Static equipment aimed at recovering waste heat;
medium could be thermal oil, saturated and superheated water.
It could be exhaust gas boilers, economizers, hot oil heaters.
At service of gas turbine, standby power station, diesel engine.
Our solution fit steadfast resistance to vibrations and easy to clean. Duty up to 30 MW.
