Vacuum drying
The coated and pre-dried coils are pushed onto special goods carriers and then placed in a vacuum oven at up to 150 °C. With a drying time of 12 to 30 hours, the residual moisture and solvent residue are removed from the coils.

Pressure monitoring
Monitoring the air pressure in the vacuum dryer
A pump is used to generate a vacuum in the chamber. The pressure at the pump must be monitored to ensure a smooth process and control of the vacuum.
Ensuring system availability
Enhancing performance
Quality assurance
Solution
Pressure sensors from ifm measure the pressure precisely to ensure production quality.
Recommended products
Temperature monitoring
Ensuring the correct temperature in the vacuum dryer
Reliable temperature measurements and control are required to ensure that the coils reach a defined level of residual moisture and are free of solvent residue at the end of the drying time. Unnoticed deviations can lead to reduced quality and even the loss of margins, resulting in significant costs.
Enhancing performance
Quality assurance
Solution
Conventional temperature sensors can drift over the course of time, which leads to quality problems. ifm temperature sensors use pt1000 sensor elements for exact and consistent temperature measurements in aggressive environments.

Ambient temperature monitoring
Ensuring the correct temperature in the vacuum chamber
A homogeneous temperature distribution is required to ensure that the coils reach a defined level of residual moisture and are free of solvent residue at the end of the drying time. Unnoticed deviations can lead to reduced quality and even the loss of margins, resulting in significant costs.

Volumetric flow monitoring
Maintaining a correct airflow in the vacuum chamber
To ensure continuous drying of the coils, a uniform air flow and a homogeneous temperature distribution must be provided. Unnoticed deviations can lead to reduced quality and even the loss of margins, resulting in significant costs.
Enhancing performance
Quality assurance
Solution
Conventional electromechanical airflow sensors may fail or drift after repeated cycles, leading to undetected quality defects and unplanned costly downtimes. SL electronic flow meters from ifm are able to measure airflow and temperature reliably and consistently, thereby preventing mechanical sensor failures.

Safety door switches
Safeguarding access to sensitive or hazardous processes
Drying chambers require a continuous process in an environment that is potentially harmful to people. The protection of doors with safety products allows for risk-free operation. In this way downtimes and quality loss including loss of margin can be prevented while cutting costs.
Enhancing performance
Quality assurance
Solution
Non-contact magnetic sensor from ifm can monitor the status of doors. * PL e to ISO 13849-1 and SILCL 3 to IEC 62061 can be achieved when used with suitable evaluation units. Concealed installation behind stainless steel allows enhanced tamper prevention.
