SmartDry Benefits at a Glance
• Improved product quality. SmartDry produces drier plates with no oxygen present.
• Huge energy cost savings and increased productivity. An improved basket design, new blower configuration and insulated firebox ensure faster drying times.
• User friendly. Automatic start-up functions and easy maintenance make running SmartDry a cinch.
• Advanced safety features. A large, fail-safe load/purge door; quiet operation; and other safety features make SmartDry not only a smart choice but a safe one too.
Tiegel's SmartDry revolutionizes the way negative and positive plates are dried-producing higher quality plates in half the time. SmartDry's AutoDry and AutoCool features work together to accurately determine when plates are dry. This way, plates are dried "just enough" every time, eliminating the guesswork of drying. While at the same time, SmartDry's insulated firebox and other design improvements speed up the drying process. The result is more efficient, faster drying; better quality; and dramatic cost savings.
Improved Product Quality
SmartDry consistently produces a drier plate, removing moisture down to 0.1 percent, while cutting PbO content to less than 3 percent. The increase in free lead available ensures superior negative plate performance while low temperatures keep the passivation of the positive plate to a bare minimum.
Tiegel makes this winning combination possible with its unique AutoDry and AutoCool features. These advanced features shorten the drying times for less deterioration of the plates. AutoDry accurately determines when the plates are dry by continuously monitoring the plates. AutoCool ensures that the water leaving the machine is always the same by auto-controlling the amount of water entering the machine. Low-pressure, 85º F (30º C) water for cooling is acceptable, minimizing the problems for cooling towers.
Dramatic Energy Savings and Enhanced Productivity
Greatly increased dryer performance and improved basket design allow SmartDry to process 2,050 automotive (4-3/4" x 5-5/8" x .065" thick) plates on racks per cycle in under 55 minutes. (It will also dry 2,000 automotive plates in formation cassettes in under 30 minutes.) This combination translates into lower costs and increased production.
Utilizing a new blower configuration, SmartDry reduces the drying time by 33 percent. Additionally, Tiegel has reduced its main blower motor to under 5 HP, which reduces total power consumption to under 5 kW.
By insulating the firebox, SmartDry increases the drying temperature by 20º F (11º C), which substantially reduces drying time without creating decomposition or auto-ignition problems.
1. Auto Pilot
Once started, SmartDry automatically purges the whole oven of any combustible gases in less than 30 seconds by opening the large loading door. After the purge cycle is complete, Auto Pilot automatically turns off the main blower and switches the butterfly valve to low fire. From there, the pilot is ignited automatically. A moisture proof flame rod assembly prevents false signaling of lack of flame due to moisture. If ignition is successful, a green ready light illuminates on the control panel, indicating that the dryer is ready to process plates. What's more, all functions are set into motion with the turn of just one switch!
1. Auto Process
To process plates, the operator simply loads the basket into the dryer and pushes the Process Start Button. Then, the burner comes up to high fire and the main blower comes on-line followed by the loading door automatically closing. After drying, a white light illuminates, signaling to the operator that the plates are dry and the loading door will open in 5 minutes or less (if adjusted by the operator). With SmartDry, there is no process clock to set, because the dryer always knows when the plates are just dry enough. Additionally, Tiegel has eliminated the need to handle the main drop-out gas valve or loading door.
AutoDry and AutoCool work together to dry the plates as fast as possible to the same level of dryness every time. They also keep cooling water and gas consumption to a minimum. AutoDry determines the exact level of moisture in all plates. This feature also compensates for tight basket packing by increasing the drying time, and automatically adjusts for changes in product type. The operator can select the level of dryness required by simply changing the AutoDry set point. Tiegel's unique AutoCool feature introduces just enough cooling water to remove moisture as it leaves the plates. Cooling is automatically reduced as the amount of moisture leaving the plates declines.
1. SmartDrive Option
This feature provides automatic adjustment of blower speed to compensate for back pressure differentials when changing from group drying to cassettes or rack drying. This further maximizes the drying speed of the oven by 50 percent. SmartDry also eliminates the blind current problem, since if only 2 HP is required, that is all the power that is supplied, even though it has a 5 HP motor.
1. Easy Troubleshooting
Veriflame flame control gives a clear indication of basic combustion interlocks such as high/low gas, combustion air, flame signal and high/low fire. This makes troubleshooting a snap.
The control box displays the temperatures of the process air, exhaust stack, AutoDry and water outlet. This allows the operator to detect and correct malfunctions such as lack of cooling, without the machine shutting down while processing plates; hence product loss is reduced. Cooling tower status is also indicated.
