Why use RES Heat Seal Controls?:
Vertical and horizontal form/fill/seal bagging machines
Bag filling and closing machines
Group packaging machines
Machines are operating faster and many films are more difficult to seal
Consistent sealing with integrity is essential under all operating conditions
Machine users are demanding longer life for heatseal elements
Machine down time is more costly and must be avoided
Customers are demanding better packaging quality
RES temperature controllers provide reliability and functionality built upon 25 years of product development and know how.
Vertical Heatseal Tools
Hot Air Blowers
Contoured Sealing/Cutting Tools
Special Heat Conductors
The heat is produced exactly when and where it is needed.
Instantaneous response to thermal changes
Temperature measurement is accomplished directly by instantaneous electrical quality (voltage and current) with high sampling rates
Virtually lag free data measurement
The small mass of the heat seal element allows for:

They are used in:
Why do you need RES temperature controllers?
What is the functionality of the RES temperature controllers?
Without the use of sensors, they precisely measure and regulate the temperature of the heatseal elements such as:
How does the RES temperature controller work?
By the use of continuous current and voltage measurements the controller monitors the change of resistance in the heatseal element caused by the temperature variation. This measurement cycle is executed 50 times/second (50 Hz) or 60 times/second (60 Hz).
The controller then maintains the heatseal element temperature at the pre-selected set-point by adjusting the primary voltage of the power transformer by use of "phase-control". Any change in the heatseal element temperature causes a corresponding change in its resistance. The controller recognizes the changes and instantly responds. So it is assured the actual temperature is always equal to the pre-selected set-point. Even infinitesimal thermal changes are instantly recognized and corrected with precision.
The advantages of RES are:
