Celdek pad is made of specially impregnated cellulose and treated to provide efficient watts. Paper ambient condition 25°C - 45°C. Estimated cooling load: 101,520 BTUs/Hrs. Total water flow 7.56 LPM per sq.ft. of the top pad surface. Bleed of equal to 10% of total water rates. High saturation efficiency. Self cleaning feature. No setting or Shrinkage of product. Low pressure drop characteristics. Impregnation makes the material stiff and self supporting. CeL Pad Cross angle : a = 45° b = 45 ° Nominal Efficiency : 88% Bleed 10% Temperature :10 to 12°C Below ambient @ 45% RH. Cooling Pad Size : 5mtr x1.5x 100mm Line filter : Automat Make Evaporative Cooling System (ECS): Fan & Pad system (with Celdak Cellulose Pads to acquire proper CFM of air movement per sq.ft. of area will be provided. Even water delivery through distribution pipe will be ensured. Water bleeding mechanism will be built in to lessen water pollution. The Bleed off rate will be set to a 10 w valve (Through BCW technology) 5% less than the evaporation rate. Slow water contamination and efficient water flow, online water filter, capacity calculated on required water flow rate will be provided. Shutters come with automatic shutter opener. This opener system allows the shutters to fully open as soon as the fan starts to run. Air delivery normally lost due to dirty shutters or to hold shutters open is thus eliminated.
