7.Number of CellNB:

1.Total pump head required for cooling tower circulationpump is the sum of condenser water pressure drop,

piping friction loss and tower head.

2.Nominal Tons are defined as 13 Ltr/min/Ton (3.43 US,GPM/Ton), Cooled from 37 deg C to 32 deg C with 27

deg C wet bulb temperature.

Cooling Tower Infill

ART-H & X Series Counter-Flow Infill improves water distribution by splitting the water streamas it descends through the fill pack. Artisans ART-H & X series design splits the water stream 8

times in a 12 (305mm) vertical path. High thermal performance ( high KaV/L) and low pressure


3/14

drop are achieved through engineered flute/microstructure design and the highest manufacturing

standards.

1. Bonded edge with dedicated bond points for added durability.

2. Engineered microstructure for improved water distribution and thermal mixing.3. High thermal performance.

4. Improved water distribution.

5. Square pack that efficiently direct water to both sides of sheet.

6. It is designed according to the water quality.
