Adhesion water dryers and curing ovens

ENERGY-EFFICIENT DRYING AND OPTIMAL CURING WITH TARGETED AIR DISTRIBUTION

Dryers are used to complete the pre-processes of ‘cleaning’ or ‘coating’.

Adhesion water dryers or curing ovens are used for this purpose. The difference between the two systems lies primarily in the heating method and the temperature level.

Our dryer designs are based on the current dryer and oven standard DIN EN-1539. We also have extensive experience implementing AMS 2750 for the aerospace industry. The drying and curing process is crucial to ensure that surfaces are free from water and the coating is 100% cured.

We plan, manufacture, and install your curing oven all in-house. Our many years of experience are incorporated into every project we handle. Our solutions are intelligently designed to ensure optimal airflow, heat transfer, and maintainability.

Our individual solutions are tailored to your parts. This enables us to provide the ideal setup for your needs.

WE LOOK FORWARD TO DEVELOPING YOUR SOLUTION!

Adhesion water dryers:

In the adhesion water dryer, the water present on the workpiece is optimally dried. Specially developed air nozzles are used to create a turbulent airflow around the workpiece. This allows the drying temperature to be reduced to a minimum.

Pass-through curing oven

This is the simplest form of a curing oven. Parts are conveyed through the oven using a conveyor system. The curing time is defined by the conveyor path and speed. These ovens are typically built without doors, but they include airlocks.
Energetically, this is the most expensive solution, but the initial investment is low.

A-Slotted curing oven

The A-oven is the most energy-efficient solution. Additionally, no doors or airlocks are needed for this system. It requires a sufficiently tall hall space. The A-oven is primarily used for smaller parts.

 

Batch curing oven:

In most cases, a batch curing oven is used. The openings are closed with doors during the heating process and after each cycle, which saves a significant amount of energy. Workpieces are placed in the batch oven and remain inside until the preset curing time is completed. Airlocks can be installed for large openings to further reduce heat loss.

 

Gelation zone / Locks:

A gelation zone is used when frequent color changes are required. The zone is supplied with hot air, which is generated by the curing oven’s ventilation unit. The curing process begins here, as the powder coating is melted at a low temperature, ensuring high-quality results. The gelation zone can also be considered a temperature airlock, preventing excessive heat loss into the workspace.

 

Door system:

Our oven systems use custom door systems. Depending on part dimensions and available space, we plan either hinged or sliding doors, which can be single or double doors.

Special attention should be paid to the double sliding doors. These doors are motorized, can be individually opened or closed, and integrate complete safety in the drive system, eliminating the need for additional safety strips that need annual checks and replacements.
