CELdek Evaporative Media Guide
Product Description
Munters CELdek is a high efficiency evaporative cooling media that is engineered to provide maximum cooling and humidification, low pressure drop and years of reliable service.
CELdek Features:
High Cooling Efficiency.
Exceptional cooling rates are achieved due to the design, manufacturing and materials used in CELdek.
High Face Velocity
The shallower angle of Munters unequal flute design allows high velocity air to travel through the pad without water droplet carryover.
Self-Cleaning Designs
The steeper angle of Munters unequal flute design flushes dirt and debris from the surface of the pad. This cleaning action directs water toward the air entering face of the pad where it is needed most.
Low Pressure Drop
The shallow angle of Munters unequal flute design allows high velocity air to travel through the pad without significant resistance or water droplet carry over.
Simple to Maintain
In most cases, routine maintenance can be performed while systems are still operating. When properly maintained, Munters CELdek pads will provide many years of highly efficient cooling and humidification.
The steeper angle directs more water tothe air entering side of the pad,where it is needed the most.
Options
Ml-T-edg Protection:
Protective Edge Coating MI-T-edg algae resistant edge coating is available for all sizes of CELdek evaporative cooling media for longer pad life and easier cleaning.
Munters MI-T-edg is a tough and resilient edge treatment applied to the air entering face of a CELdek pad. It has been formulated to withstand repeated cleaning without damaging the pad.
Algae and Weather Resistant
Munters MI-T-edg is nonporous and quick drying. It prevents algae and minerals from anchoring themselves into the substrate of the pad, so they slough off when dried. MI-T-edg also protects CELdek pads from the damaging effects of severe weather and long term exposure to UV light.
Extends the Life of Pads
Munters MI-T-edg protective edge coating extends the life of the pad over that of non-treated pads.
Design Considerations
Water Distribution
Water flow rates vary based on the depth of the media. CELdek requires 1.5 gallons per minute of water per square foot of horizontal (top) pad surface area. For installations that have intense evaporation or pad walls taller than 72″, an additional 10-20% of water may be necessary.
Supply
The gutter and sump should be sized to supply the system with enough water to operate at its maximum flow rate and not overflow when the system is shut down.
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, and Munters 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.
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.
Munters maintenance bulletins provide information to help maximize the efficiency and life of CELdek evaporative pads.
Selection
The depth and height of media varies depending on the application. CELdek may also be cut to fit smaller equipment. Call Munters for help in determining the requirements of specific installations.
Distribution Pads
CELdek is designed to distribute water from the front to the back of the pad. For lateral distribution, a 2″ or 3″ distribution pad should be used. These specially designed pads are also protected with Munters patented edge treatment.
