Electrical Diagram
Direct Evaporative Cooling
Direct evaporative cooling exchanges sensible heat for latent heat,

  and follows upward along a constant wet-bulb temperature line one the Psychometric Chart. The result is a dry-bulb temperature of the leaving air (B) approaching the wet-bulb temperature of the entering air (A).
  Whenever water is evaporated, heat is absorbed. This basic principle underlines the design of the MEGA COOL direct evaporative cooling.
     
Evaporative Cooling Media
Media : Carton Cellulose material  
Design : Cross fluted continuallt directs  
      water to the Air-Entering side  
Water Direction : From Top to Bottom  
       
Cooling Pads Frame
Media : Stainless Steel or Galvanize Steel

Design : To keep the Cellulose in good Condition
     
     
     
Water Distribution
Water distribution was designed equally to all cooling pads

  through special 8mm diameter Holes, fixed on plastic pipes ( to prevent scaling inside holed ) and distributed as three holed for each cooling pad
Water Tray is designed in unique way to guarantee continuous water flow from the sides

Important Notes :
    (1) to improve efficiency, air must be discharged (i.e open windows / doors / louvers)
    (2) to increase cooling rate, we recommend installation of wall mounted fans, which will increase air speed and reduce humidity
