ROOF WARNING, OPERATION & SAFETY Fan/Heater Application Roof Damage Warning and Disclaimer GSI DOES NOT WARRANT ANY ROOF DAMAGE CAUSED BY EXCESSIVE VACUUM OR INTERNAL PRESSURE FROM FANS OR OTHER AIR MOVING SYSTEMS. ADEQUATE VENTILATION AND/OR "MAKEUP AIR" DEVICES SHOULD BE PROVIDED FOR ALL POWERED AIR HANDLING SYSTEMS. GSI DOES NOT RECOMMEND THE USE OF DOWNWARD FLOW SYSTEMS (SUCTION). SEVERE ROOF DAMAGE CAN RESULT FROM ANY BLOCKAGE OF AIR PASSAGES.

Fan/Heater Application SAFETY ALERT DECALS FAILURE TO INSTALL THERMOSTAT INCREASES RISK OF FIRE IN BIN! WARRANTIES ARE VOID ON HEATERS INSTALLED WITHOUT THERMOSTATS. CAUTION! BE VERY The GSI Group, Inc. recommends contacting your local power company, and having a representative survey your installation so the wiring is compatible with their system, and adequate power is supplied to your unit. Safety decals should be read and understood by all people in the grain handling area.

FAN APPLICATION GUIDE Fan/Heater Application Vane Axial Fans 3500RPM Vane Axial fans are normally high performance low static pressure fans. They are normally used for inbin drying or aeration on shorter tanks or when low resistance grains (corn, soybeans are processed. The application should be looked at very closely when aerating unusually tall tanks or high resistance grains (wheat, milo).
PAGE 7
FAN APPLICATION GUIDE Fan/Heater Application 1750RPM Centrifugal Fans 1750RPM Centrifugal fans are normally high performance, medium static pressure fans. They are normally used for aeration or drying on shorter tanks or when low resistance grains (corn, soybeans) are processed. These fans may be used with gas heaters, either mounted on the inlet side of the fan or downwind on the outlet side. Greater airflow is attained when the heaters are mounted downwind.

FAN & ROOF VENT SELECTION STEP 1. Fan/Heater Application Determine the average grain depth STATIC PRESSURE from Step 3, and the CFM for a desired bin size: PER FAN from Step 5, select the fan best LEVEL FILL -AVE GRAIN DEPTH (ft) = EAVE HEIGHT (ft) - FLOOR HEIGHT ft) PEAKED FILL- AVE GRAIN DEPTH (ft) = meeting the requirements. For best fan performance, a fan should run in the mid-range of is static pressure ratings, if possible.

Fan/Heater Application AERATION SYSTEM REQUIREMENTS Full perforated floors are recommended in most DRYING situations. Floor gauges and support spacing are dependent on the grain load for a particular bin size. Please inquire as to exact specifications. Flush floor (formed in concrete) systems are recommended when aeration only is desired. The two most important aspects of aeration design are the total perforated floor area and the entrance duct cross-sectional area.
PAGE 10
EXAMPLES SITUATION: On farm aeration of dry soybeans. 42" diameter, 9 rings, NSL series farm bin with 24" eave height. A flush floor aeration system with one fan will be used. 1. AVE GRAIN DEPTH, peaked = 24' + (42' /12) = 27.5' 2. Select 1/10 CFM/BU aeration rate for beans 3. From the STATIC PRESSURE TABLE for BEANS at 28' (use the next higher value or approximate) and 1/10 cfm/bu the static pressure is .91" of water. .91" water column 4. Bin capacity, BUSHELS 27.5' x 0.
PAGE 11
SITUATION Fan/Heater Application SITUATION: On farm in-bin drying of corn, 24' diameter, 6 ring, FCDL series farm bin with 22' eave height. Tank will be layer filled to level full. The drying systems will consist of a full floor with 12" plenum, stirring device, one fan and heater. 1. AVE GRAIN DEPTH, level = (6 rings x 3.67) - 1 (floor) - 2 (stirring device) = 19'. 2. Select 1 CFM/BU for heated air drying of corn. 3.

Fan/Heater Application Aeration This ventilation of stored grain to maintain uniform moisture and temperature, uses low airflow rates and unheated air. The lowest rates are for dry grain and higher rates are for higher moisture contents.

Fan/Heater Application HEATER APPLICATION & SIZING Fan selection and examination of a customer's drying requirements should precede heater selection. Generally, the size and type of fan, vane axial or centrifugal, limits the choice of heater to be used in a particular situation. For best results GSI heaters should be matched with GSI fans. When using more than one fan and heater on a bin they should be of like sizes. and heaters are being connected.
