The patented Electronic Monitoring Control System (EMCS) offers computerized control of all dryer functions. This "smart" system eliminates guesswork by providing the operator instant information on a large backlit LCD display.

Standard Tower Dryer Operational Features
Standard operational features on the Tower dryer include double Maxon gas blocking valves on the gas train, exhaust air temperature sensors, plenum high temperature limits, grain level monitoring, continuous flame monitoring, airflow monitoring and motor overload monitoring. GSI also provides a two year parts and labor warranty on Tower Dryers, one of the best warranties in the industry.

1. Gravity inlet does not require leveling auger, reducing the number of moving parts.
2. Self cleaning cushion box on plenum roof reduces grain damage and plenum roof wear.
   
3. Stainless Steel outside sheets greatly extends the life of the dryer. The screens utilize different size to
   reduce emissions.
   
4. The 12-3/4” grain columns surrounding the heat plenum chamber allows the grain to receive all BTU’s from the burner, improving efficiency while providing superior noise reduction.
   
5. Heavy-duty overall construction results in an extra rigid structure on a minimum of ground space.
   
6. Uniform low velocity heated air improves
   efficiency and quality as well as reducing particulate emissions.
   
7. Inside and outside safety ladders, cages and catwalks provide safe and easy access to all areas of the dryer.
   
8. Patented Grain Inverters are used to equalize column moisture content and temperature of the grain column, greatly improving quality and efficiency.
   
9. In-line Maxon NP-LE-AL series burners provide even heat and efficient combustion from either natural gas or LP vapor. Aluminum extrusion reduces burner maintenance.
   
10. Reducer cone equalizes air velocity past burners for optimum combustion and provides step-in access to burner assembly.
    
11. Walk-in heat section provides easy access for interior cleaning.
    
12. Divider hopper separates the heating and
    cooling sections while preventing build-up
    of particulate matter.
    
13. Internal mounting provides the added benefit of ultra quiet operation as the surrounding grain creates a natural noise barrier.
    
14. Internally mounted tubular centrifugal blowers deliver high volumetric airflow to the pressure heat and suction cool sections.
    
15. Recycling heat from the cooling grain results in significant fuel savings.
    
16. Walk-in cool section provides easy access to blowers and metering system.
    
17. Patented discharge system provides simple, uniform metering and quick dryer clean out.
    
18. Industrial quality components (including Maxon valves and burners) ensure years of reliable service.
    
19. Weather-proof NEMA IV cabinets and NEMA rated electrical components ensure safe and reliable operation in all conditions.

PLC Control System provides one of the most advanced and reliable dryer controls on the market.

Discharge Area
Cool, dried grain passes from the cooling section of the dryer into the sealed, hoppered discharge section. Grain is gravity fed down a 45 degree hopper to GSI's patented metering drum. This drum provides a positive, yet gentle means of metering grain uniformly from each column of the dryer and discharging it out the center of the dryer. The drum is driven by a variable speed inverter operated AC motor. The hopper bottom design of the dryer eliminates troublesome sweep augers and sweep arms and provides for quick dryer clean-out.

Sidewall Sheeting
Each GSI Tower dryer features a bolted design, rather than welded, which permits the wide use of galvanized steel ( versus painted steel ) throughout the dryer. In addition, all Tower dryers have stainless steel, roll formed exterior sheeting as a standard feature. These design features simplify dryer erection, improve dryer appearance and promote a long dryer life.

GSI Tower dryers are designed to retain bees wings and particulate matter within the drying columns. The largest standard hole size on the exterior screening of the dryer is 0.078 inch diameter perforation. After the grain is turned, the perforation size drops to a diameter of 0.0625 and 0.056 inches. Solid non-perforated exterior sheets are used at the grain turners and at the top and bottom of the grain columns to help reduce particulates from being expelled from the dryer.
