HOW THE TURBOCELL EVAPORATIVE COOLER WORKS Whenever drinking water is evaporated, warmth is absorbed. Moist the back of your hand, then blow on it. The skin surface area is immediately cooler. This demonstrates the basic principle of evaporative cooling. The Turbocell works by drawing outdoors air via a uniquely developed cross-fl uted media. Due to its internal geometry, a turbulent mix of air and drinking water is created which optimizes warmth transfer. An air washing effect is also created which removes most dust and dirt from the air stream before the air fl ows into the work region providing a clean, awesome environment. WHY EVAPORATIVE COOLING IS COMFORTABLE Lowers Temperature. The Turbocell pumps in awesome air lowering room temperature. Lowers the Temperature You Feel. The rapid shifting air produced by the Turbocell increases skin surface area evaporation. This leads to effective cooling meaning people feel three to 5 degrees cooler than the temperature read from a thermometer. Carries Away Radiated Warmth. A constant fl ow of awesome air removes warmth from the work place leaving a much more comfortable surrounding. New Air. The Turbocell offers new, revitalizing air, forcing stale air out. Cleans Air.

Reduce the building dimension by the room taken up with machinery, inventory, etc. (Building dimension in ft3 ) - (Machinery, etc. in ft3 ) = (Space to chill in ft3 ). Step seven. Divide the (Space to chill in ft3 ) from step six by the (Number of minutes needed for each air change) from step four. This gives the CFM score from the Turbocell Device. Step eight. Refer towards the “Air Delivery Table” to select the Turbocell Model No. If the needed CFM score falls between designs select the larger from the two. EXAMPLE: Step one. Small radiator factory located in Mobile, AL. See “Cooling Zone Map” to get Zone four. Step 2. Factory has solder dip tanks that give off warmth. Interior warmth load is “Excessive.” Step three. Factory is exposed to sun throughout the day. Sun protection is “Poor.” Step four. From “Air Change Table” get one /2 moment for each air change. Step 5. Calculate the dimension from the factory. (50 ft. length) x (30 ft. width) x (ten ft. height) = 15,000 ft3 . Step six. Room occupied by machinery and inventory is 2,200 ft3 . (15,000 ft3) - (2,200 ft3 ) = twelve,800 ft3 . twelve,800 ft3 Step seven. CFM score = = 25,600 CFM one /2 min. Step eight. From the “Air Delivery Table” select Model HECD-260. Place COOLING: The quantity of air for each work station depends on the amount of activity, the degree of warmth to overcome, and the distance between workers and air discharge. The quantity of air usually varies from 500 to 5,000 CFM and the air velocity at the worker should range from 400-1000 FPM. The awesome air discharge should be no much more than 4-10 feet from the worker and be directed towards the upper body region. The air outlet should be adjustable so the direction of fl ow may be controlled. Due towards the complexity of sizing models for specifi c place cooling applications please contact the Alton Sales Department for assistance. SELECTING A TURBOCELL The Turbocell may be accustomed to region awesome or place awesome. Region cooling is accustomed to awesome a whole work region where workers constantly move about and cooling specifications do not vary greatly from one location towards the next. Place cooling is utilized when building quantity is big and workers are located near machines that give off warmth. Awesome air from the Turbocell is distributed via ductwork and discharged straight on the workers.

Select the zone from the “Cooling Zone Map.” Step 2. Decide if the interior warmth load is “Normal” or “Excessive.” “Normal” means no warmth producing equipment or big crowds. “Excessive” means an region with warmth generating equipment or a sizable number of people. Examples of warmth generating equipment are big motors, stoves, ovens, or industrial procedure equipment. Step three. Decide if the region to be cooled is protected from the warmth from the sun. A “Good” sun protection is one where the building is insulated or even the exterior walls are shaded. Windows do not face the sun during the warmth from the day. A “Poor” sun protection is one where the building is uninsulated, sun beams down on the building and windows face the sun during the afternoon hours. Step four. Refer towards the “Air Change Table” and determine the number of minutes needed for each air change. Step 5. Calculate the building dimension. (Length in ft.) x (Width in ft.) x (Height in ft.) = ft3 . Note: If the building has a very higher ceiling, use a height of 15 to 18 feet. The Turbocell should be installed so it discharges into the reduce part from the room while an exhaust fan draws air from the upper degree.

FC six ALTON MOTORIZED Quantity CONTROL DAMPERS The Alton HECD Turbocell Sequence offers an optional motorized discharge damper which may be ordered with both a two-position or modulating actuator. This discharge damper is a simple, yet versatile option which will greatly enhance the fl exibility from the Turbocell device. The damper system attaches towards the discharge from the blower and may be utilized as a shut-off damper or a variable air quantity damper. When outfitted with a two-position actuator, this damper system proves to be very effective at reducing air migration. The two-position actuator is developed to open the damper as the blower motor is energized, permitting optimum air fl ow as lengthy as the blower motor is running. A spring return closes the damper on loss of energy to prevent air migration in both direction. When outfitted with a modulating actuator, this damper system offers the benefi ts of a multi-speed device without the expensive electrical controls a two-speed system requires. Controlled by a potentiometer which is remotely located within the building, the damper may be adjusted from fully open, to partially opened, to fully closed when the blower is de-energized. During milder spring and fall days when full air capacity may not be needed, the damper may be adjusted until the desired amount of air fl ow is established. As the damper is closed, the resistance on the blower leads to a totally free wheeling action which, exams have confirmed, actually reduces the energy consumption from the blower motor. The modulating damper system offers far greater fl exibility than the typical high-low procedure of a two-speed motor, while also providing greater savings for you. Field outcomes have confirmed the motorized discharge damper option may be a valuable addition to your Alton HECD Turbocell device.

TYPICAL WIRING DIAGRAM 14 This distinctive crossfl uted style from the pads induces extremely tur bulent mixing of air and drinking water for ideal warmth and dampness transfer. The internal geometry from the pad . . . a “built-in angle”. . . regularly directs the drinking water towards the air entry aspect. This leads to: one. Much higher cooling effi ciency - up to 90% within the 400-500 FPM velocity range in a typical 12" depth of Turbodek . . . slightly higher in Fiberdek. 2. Much higher face velocity - because from the “built-in angle”, the optimum air velocity without drinking water carryover is approximately 750 FPM for Turbodek. This compares to approximately 200 FPM for conventional pads! three. Self-cleaning style - Turbodek pads are unaffected by atmospheric dust or sand. When the recirculating drinking water is turned on, especially without air fl ow, the drinking water fl ushes the surface area locations, using the greatest concentration at the entering aspect where debris normally accumulates. This also serves as protection against mineral buildup. Air Velocity (FPM) Typical Evaporative Cooling Effi ciency (Dotted Line) Typical Air Pressure Drop ("W.C.) (Solid Line) ALTON TURBO DEK . . . is a broad name accustomed to describe our Turbodek and Fiberdek evaporative pads.

NOTES (one) The 87% effi ciency utilized within the example will be the Turbocell minimum effi ciency as determined by factory exams. With proper maintenance, the Turbocell higher effi ciencies remain constant throughout the lifestyle from the device. (2) Air removal is definitely an essential factor in maintaining ease and comfort in an evaporative cooling system. Air removal will prevent an uncomfortable build-up of humidity in addition to keep the air in circulation. An exhaust fan is extremely recommended. In locations such as restaurant kitchens or hotel laundry rooms, where odors should remain within the room when doors are opened, the exhaust fan should be sized approximately 110% from the Turbocell score. This will produce a negative room pressure, thus causing the air movement to be into the room rather than out when the doors are opened. In other cases, such as a coin operated laundry, where it is desirable to greet customers with a awesome breeze upon opening the door, the exhaust fan should be sized approximately 90% from the Turbocell score. This will produce a positive room pressure, which will cause the air movement to be out from the room when doors are opened. This will also assist prevent outdoors air from entering .
