Air Finned Cooler For Mechanical Seals

Expert Engineering Enhanced Air
Finned Cooler is unique in design. In which the Process Liquid flows from the
pot (as the direction shown in the fig. Expert Engineering Air Cooler) and the
cooling Finned Tubes and inserted in the pot, which cools the Process Liquid when it comes in contact with Tube


Cooling Finned Tubes.
The tubes are consists of sealed Stainless Steel tubes with Copper/Aluminium fins around it. It is filled with a liquid (the thermal transfer medium) appropriate to temperature of application.

Working Principle of Finned
Tubes It is filled with a liquid (the thermal transfer medium) appropriate to
temperature of application. The working fluid evaporates extracting
heat from the process liquid Vapor moves towards fin side of the tube
wherein it dissipates heat to the ambient and condenses.
The condensed liquid comes back to the bottom portion.
The cycle repeats,
BENEFITS OF AIR COOLER
Reliability:
Direct saving
Cost of Water: With Air Fin Coolers no water is required hence cost of water is saved.
To get desired amount of cooling normally for water-cooled heat exchangers 40 to 50
lpm water is required. @ Rs 5 per cubic meter approximate saving will be about Rs.
110000/- per year.
Cost of circulation of water: The energy spent in water circulation in is saved. On an average about 0.5kW of power is required for recirculation of water in each cooling circuit. @ Rs 4.5 per kw the power cost would be Rs.19710/-
Preventive Maintenance: Water causes scaling problem, and due to scaling, temperature to the seal goes up, the pump needs to be taken for removal of scale. Cost of removal of scale and loss of production is saved with Air Fin Coolers. Cost of each shut down is between Rs. 50,000/- to Rs. 1, 50,000/- (depends on criticality and cost of the product.)
Shut down Maintenance: If seal fails because of poor cooling in addition to the
production and maintenance loss, cost of replacement seal components add to the loss.
The cost incurred varies between Rs. 75,000/- to Rs. 5, 00,000/- depending on the seal size and spares consumed.
Indirect saving
Fouling: In absence of water, no scaling can take place. Because of scaling heat transfer gets reduced, hence either water consumption goes up or temperature in seal area goes up which reduces the seal life.
Better circulation of flushing fluid: In absence of coil, friction loss reduces hence there is better circulation of flushing liquid. The seal will be more comfortable with increased amount of flushing liquid, as there is no friction
