The following areas :
- Generator rooms
- Gas turbine intakes
- Industrial cooling of hot spots
- Hot zones
- Comfort cooling
- Commercial agriculture
The features of these cooling units are mentioned below :
- Less energy consumption
- Low maintenance costs
- Less space required
Details :
- FRP Tank or Hot Dip Galvanized tank(TEFC motor)
- Cellulose Pads
- Submersible/mono bloc pump
- Canvass connection & damper
- Single skin/double skin with SS Tank
- High evaporation efficiency
- Superb wetting properties
- Low pressure drop when wet, leading to lower operating costs
- No water carry-over
- Low scaling
- Self cleaning
- Strong and self supporting
- Long life time
- Excellent cooling efficiency due to the unique design, manufacturing methods and materials used
- High face velocity allows the air to travel through the pad without water droplet carryover
- Low pressure drop allows the high velocity air to travel through the pad without significant resistance
- Self-cleaning design due to steeper angle of unequal flute design, flushing dirt and debris from the surface of the pad
- Simple to maintain due to the fact that in most cases, routine maintenance can be performed while systems still are operating
Selection : The depth and height of media varies depending on the application. Call Aerotech for help in determining the requirements for specific installations. CELdek cooling pads may also be cut to fit smaller equipment Maintenance Scale. Mineral deposits can be minimized by maintaining a continuous water bleed-off or by periodically dumping the sump. The methods and/or quantity of bleed-off may vary depending on the pH and hardness of the supply water. Aerotech can assist you by recommending individual bleed-off rates.
Note :
- Fractional timers should not be used. These timers do not enhance the performance of a cooling pad and actually contribute to the development of scale which will reduce airflow.
- Algae. If algae is allowed to grow freely on a CELdek pad it may eventually clog the flutes and inhibit the flow of air. This increases the static pressure and reduces the efficiency of the pad. Algae growth can be controlled by early implementation of simple maintenance techniques.
- Never use chlorine or bromine on CELdek pads.
- Maintenance bulletins provide information to help maximize the efficiency and life of CELdek evaporative pads
Scale Control :
- Maintain a pH between 7 and 9 in the sump and 6 and 9 for make-up water supply.
- Make sure the flow of water is even from one end of the distributor pipe to the other.
- Water flow should be 0.75 gpm per linear foot for a 6” pad.
- Use plenty of Bleed Off
- Algae Control
- Shade the pads and sump.
- Allow the pads to dry out completely every 24 hours.
- Avoid contaminants from contacting the pads and water.
- Dust, fumes, fertilizer, phosphates, etc. provide nutrients for algae growth.
General Rules :
- Do not cycle the pump on and off using 10 minute timers.
- This causes the pads to wear out prematurely.
- Use chemicals to clean and disinfect ONLY - No chlorine and no bromine allowed! Refer to Care Manual QM1128 for recommended cleaning products.
