Dryer

An industrial warm-air drying system can be controlled remotely when it has its own cellular connection to a cloud platform. The DENIOS Heating Box has a router with its own SIM card for this, so there is no need to integrate it into the company network. Data goes to the cloud every minute and is also stored on the HMI. Control works on site or remotely, while a small PLC regulates the warm air.

An industrial drying cabinet proves that temperatures were maintained by recording temperature curves without gaps. Chemical companies have to show clients or authorities that certain temperature windows were met. The Heating Box holds the selected parameters precisely and keeps heating until the core temperature is right. In the cloud, middleware enables reporting, export and integration into customer systems.

Savings potential on an industrial hot air dryer is found by recording its energy consumption individually rather than only at site level. In many plants it remains unclear where electricity and heat are used or wasted, and auxiliary processes such as dryers are rarely analysed. autinityE3 from Schaeffler Digital Solutions records energy data from machines, plants and infrastructure in real time. A cockpit with comparison values reveals outliers and high base loads outside production hours.

The energy demand of a dryer on a phosphating line can be reduced by lowering temperature setpoints and adjusting runtime control. This is exactly what was done on the hot air dryer in the Schaeffler Digital Solutions example. autinityE3 supported the configuration, monitored operation and validated the measure using the readings. This means the savings can be proven rather than just estimated. New plants and data points can be added step by step.
