4090 Series
4090 Product Series
In the 4090 series, wavy cellulose sheets with a wave height of 4 mm are placed on top of each other, and the wave direction of the two adjacent sheets constitutes an angle of 90 degrees (45/45) to each other
Due to its high density, these series have the highest evaporation efficiency and pressure drop. It is recommended to use these series in cooling systems possessing limited space to install thick with high air face velocity through the cellulose pads. According to the customer's order and based on the required cooling capacity, these series can be provided in different sizes. 4090 Series has a water distributor so that the pad is evenly wet and maximum evaporation efficiency is achieved.
Evaporation efficiency of the 4090 model for different air thicknesses and velocities:
| Pad thickness/air velocity | 1 m/s | 1.5 m/s | 2 m/s | 2.5 m/s |
|---|---|---|---|---|
| 50 mm | 77٪ | 73.5٪ | 71٪ | 69٪ |
| 75 mm | 86٪ | 83.5٪ | 81.5٪ | 80٪ |
| 100 mm | 91٪ | 90٪ | 89٪ | 88٪ |
| 150 mm | 94٪ | 93٪ | 92٪ | 91٪ |
