Ø T h e c o l d f l u i d c a n b e h e a t e d t o temperatures very close to those of the hot fluid due to the true counter current flow

Ø Suitable for high fouling and clogging condition

Ø Extended heating surface

Ø Space saving

Ø For air or gas application

üHigh efficiency finning üFor higher temperature applications (typically up to 300°C)üCorrosion protection

Extruded

Air Cooled Heat Exchanger The hot process fluid to be cooled flows through finned tubes while the cooling air flows across the outer surface to remove heat. The cooling air is propelled by axial fans in either a forced draft or induced draft configuration.

Applications/Indusrty• Oil and gas refineries• Waste to energy• Plants producing ethylene, biplastic, glass fibre• Ammonia and urea handling plants

KAWAN is experienced in manufacturing air cooler with different types of finned tubes

R

A water cooled heat exchanger for the exhaust steam from the steam turbine in thermal power plants. It maximises the steam turbine efficiency by converting the exhaust steam into the condensate. Heat from the condensate could then be reclaimed for boiler feed water.

Steam Surface Condenser

Steam Surface Condenser

KAWAN provides steam surface condenser, steam jet ejector, inter/after condenser, valves/pipng and condensate pump as a complete system.

A vacuum venting system, such as steam air ejectors is used to remove any air entering the s y s t e m a n d n o r m a l l y c o m b i n e d w i t h intercondensers and/or aftercondensers for the purpose below:

Øto condense as much vapor as possible from

the preceding stage

Øto reduce the amount of gas to be compressed

by the next succeeding stage

Øto recover condensate.

Clean Steam Generator

Clean Steam GeneratorClean steam generators produces clean steam from demineralised water.

All the clean steam contacted parts are made of stainless steel.

The clean steam generator is with 'U' type extractable tube bundle and “kettle” shell type

Typical application:

ØPure steam processes in the food or

pharmaceutical industry

ØSterilising equipment in hospitals

ØProduction of high-purity products

HIGH PRESSURE WATER JETTING SERVICESKAWAN provides hydro jet t ing serv ice providers serving the needs of refineries, chemical plants and shipyards. The hydro jetting pressure ranges from 110- 120 barg, with diverse services f rom tank c leaning, tubes lancing, sur face preparation to cold cutting and general cleaning requirements.

HEAT EXCHANGER RETUBING

Provision of in-house or onsite re-tubing services

R

• induce turbulent flow in tubes• Increase tube side heat transfer coefficients up to 2½ times larger than the equivalent smooth tube with the gain in pressure drop less than 2½ times• Tube wall temperature more closer to tube side fluid• Reduce fouling potential and heat exchanger size

• Low fouling potential due to better surface finish• Increased ability to withstand pressure• Uniform in shape• Great strength under loading

• Ti welded tube provides best corrosion resistance for sea water application• Thin wall design possible with constant thickness• More economical

• More surface per foot of tube - up to 50% more.• Increase turbulence and mix the fluid to form a more uniform temperature across the fluid• More flexibility which enable the tube to be bent at a tigher radius and thus reduce the size of heat exchanger

• Induce swirl flow of the tubeside fluid, resulting in higher near wall velocities and fluid mixing• Most effective in turbulent flows with limited pressure drop

• Available in copper, aluminium, carbon steel construction• High efficiency and very stable performanc• Extremely suitable for low air velocity environment

Heat Exchanger Tubing

• Different grades combination for tube and fin eg. stainless steel & aluminium, stainless steel & copper• Absence of crevice corrosion due to high weld integrity between tube and fin• High heat transfer efficiency
