SmartDry Benefits at a Glance
- Improved product quality. SmartDry produces drier plates with no oxygen
- Huge energy cost savings and increased productivity. An improved basket
design, new blower configuration and insulated firebox ensure faster drying
- 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
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
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.
- 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!
- 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.
- 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.
- 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.
Advanced Safety Features
- The large loading door is fail safe. If all systems fail, the loading
door still opens with only 3" of water column pressure from the main
blower. The door opens immediately upon loss of flame, electric power loss
or thermal runaway signal.
- The machine is quiet due to the lower horsepower and gas demand. There
is only 3 dB over factory background in front of the machine.
- The impeller turns at less than 1200 rpm instead of 3400 rpm.
- There are three independent control packages that shut off the main
gas or restrict the flow of gas prevent thermal runaway.
- The purge is rapid and complete. Because the loading door is open,
the 10,000 cfm blower is on during the purge cycle, and a combustion blower
purges the combustion chamber.
- There is no exhaust damper to stick.
