Moisture control in the automotive sector is one of the most critical factors directly affecting production quality, test reliability, and material durability. Uncontrolled humidity levels lead to serious problems such as paint defects, glass lamination errors, steel corrosion, battery production safety risks, and inconsistency in engine test results, reducing production efficiency, increasing costs, and compromising product quality.
Why Is Moisture Control Vital in Automotive Manufacturing?
In the automotive sector, humidity can cause different problems at every stage of the production line. From paint booths to engine test rooms, from lamination lines to lithium battery production facilities, maintaining the optimum humidity level is essential at every point. Here are the key problems that uncontrolled moisture creates in automotive manufacturing:
| Problem Area | Result and Impact |
|---|---|
| Paint Defects | Humidity-induced blistering, pitting, and adhesion problems in paint booths, resulting in a decline in surface quality |
| Glass Lamination Errors | PVB film moisture absorption, fogging and white spots between glass layers, increased rate of defective products |
| Steel Corrosion | Rusting of tire steel wires and cord fabrics, weakening of the rubber-steel bond, decline in product durability |
| Test Inconsistency | Humidity-induced sensor errors in engine test rooms, emission measurement deviation, non-repeatable test results |
| Battery Production Risk | Moisture hydrolysis of the LiPF₆ electrolyte salt (HF formation) and cathode surface degradation in lithium battery production, a threat to production safety and battery performance |
Our Areas of Expertise in the Automotive Sector
We supply humidity control equipment and support unit selection for the production and testing processes of the automotive sector. Below are the key automotive manufacturing areas we serve:
Testing and Quality Control
- Engine Test Rooms: Conducting performance, durability, and emission tests of automotive engines under stable environmental conditions. Ensuring repeatable test results within the target temperature and humidity range using dehumidifiers integrated into the central air conditioning system. Simulation of different geographic climate conditions.
Production Processes
- Glass Lamination: Prevention of humidity-induced fogging and white spots between PVB film and glass layers in laminated glass production. Maintaining clean room conditions in lamination rooms with positive-pressure ventilation and integrated humidity control.
- Paint Booths: Ensuring dry paint booth conditions before and during vehicle painting. Preventing paint defects (blistering, pitting) through humidity control and achieving flawless surface quality.
- LiBat - Dry Rooms for Lithium Battery Production: Silica gel rotor dehumidifiers for the ultra-low dew point dry rooms of lithium battery plants. Cell assembly and electrolyte filling rooms are held at about −40…−45 °C dew point (over ice) to prevent LiPF₆ hydrolysis (HF) and cathode surface degradation.
Material Storage
- Tire Wire Storage: Protecting steel belts and cord fabrics used in radial tire production at 25–30% RH levels to prevent corrosion. Homogeneous dry air distribution throughout the storage area using dehumidifiers operating in conjunction with cooling equipment.
