EVAPORATIVE FLUID COOLERS
 
   
 

VXI Range
52 models from 2 to 200 l/s

Principle of operation
The fluid to be cooled is circulated inside the tubes of the heat exchange coil. Heat flows from the process fluid through the coil tubes to the water outside, which is cascading downward over the tubes. Air is forced upward through the coil, evaporating a small percentage of the water, and discharging the heat to the atmosphere. The remaining water falls in the sump to be recirculated by the spray water pump.

Material options
Baltiplus corrosion protection
Baltiplus Corrosion Protection comprises all steel components fabricated from Z 600 galvanised steel with 600 g of zinc per mē coating. Cut edges are protected with a zinc rich paint. All fasteners have a 3-stage protective coating consisting of a zinc phosphate treatment, a zinc rich inorganic resin coating and an aluminium rich organic top coat. The exterior surfaces of the equipment are finished with a coat of polymeric zinc aluminium paint.

Baltibond Corrosion Protection System
The BALTIBOND Corrosion Protection System is applied to individual galvanized steel components prior to assembly. These components are manufactured from Z 600 mill galvanized steel sheets with 600 g of zinc/mē.
After manufacturing the components undergo an industrial cleaning and drying pretreatment process. Immediately after the pretreatment the components are electrostatically coated with a dry, polymeric hybrid thermosetting powder. The coated components are then put through a thermally activated curing process during which the powder is fuse bonded to the substrate.
Stringent quality control procedures and regular testing during the coating process assure consistent high quality of the protection system. The fasteners used for assembly have a 3-stage protective coating comprising a zinc phosphate treatment, a zinc rich inorganic resin coating and an aluminum rich organic top coat.
