Internal temperature monitoring

For optimum hardening of the components, the RDS dryers

feature internal temperature monitoring. Thermal elements

have been installed in every heating zone, which precisely

measure the temperature in the system. The values are

displayed on the monitor. As soon as the tolerance values

are exceeded, an acoustic alarm signals and the heating is

switched off.

The exceptional thermal insulation of heating

zones and the individually adjustable tempera-

tures allow for optimum proling of your drying

processes – which are perfectly adapted to the

requirements of the products.

The exhaust system ensures safe removal of solvents

among other things. Appropriate mechanisms are attached

to the input and output of the process chamber, as well

as between the heating zones. The process exhaust air is

supplied directly to the extraction through the fan. The sub-

stances to be hardened and the exhaust products released

determine the extraction volume. The extraction function

is monitored by a pressure sensor. If there is a problem, the

heating switches off automatically and the inflow of new

components is stopped. This prevents any flammable gas

mixtures from forming in the system.

Gentle cooling

to below 60 °C

After the drying process, the warm process atmosphere is extracted. Despite

this, the component still has an outlet temperature of around 60 °C. A separate

air or water-cooled cooling unit is available as an option, and can be used to

achieve signicantly lower temperatures.

In the air-cooled cooling line, the hot process exhaust air is extracted via the

attached exhaust hoses. As well as this, cold ambient air is aspirated and blown

in via the panel of nozzles to cool the components. With the water-cooled cooling

option, the cooling process is carried out via heat exchangers. There is the option

of controlling the cooling process precisely with separately adjustable fans in the

individual zones and influencing the cooling gradient accordingly.

Process documentation, traceability, etc.

The variety of MES systems on the market requires individual

adjustment of data transfer from the Rehm drying system

to the client’s superordinate manufacturing management

system (MES). Superordinate to this is the ERP system,

which the whole company keeps an eye on, and which allows

for logistic optimisations across all sites. However, the MES

system focuses on a company’s individual production lines.

Rehm uses an ROI interface (Rehm open interface) to trans-

fer individual data. Machine-specic operational data that is

due for the respective system is collected and passed on to

the MES system as a bundle.

It is possible to ensure the seamless traceability of prod-

ucts, components or batches in this way. A data set is

created for every assembly, which documents the relevant

process parameter during the run. The assembly can be

clearly identied and assigned via a barcode scan on the

assembly itself, or by scanning the batch card. Process

locking is also available as an option. Here, the scan is com-

pared with the database and the assembly is only forwarded

on to the system in the event of approval. Defects can be

detected and prevented in this way and therefore lead to

process improvements.
