Spray pretreatment tunnel

Design spray pretreatment tunnel

The design of the Glasbeek continuous or takt spray pretreatment tunnel combines modest energy consumption with excellent results. Glasbeek has the right solution for spray pretreatment of all types of metal.


Advanced technology means that the user need not be concerned about reliability, functionality or maintenance. Every spray pretreatment tunnel designed by Glasbeek incorporates all the latest developments in the fields of chemistry, technology and reliability.


It is possible to reduce consumption of water, chemicals, electricity and gas without sacrificing the efficiency and quality of a perfect conversion layer on the treated metal.


Every durable pretreatment plant constructed by Glasbeek is adapted and tailored to your product and treatment process needs. Although already well-equipped, every Glasbeek spray pretreatment tunnel can easily be expanded with carefully chosen options in order to adapt the installation even better to your personal requirements.

Long working life
Every durable Glasbeek continuous or takt spray pretreatment tunnel is the product of more than 100 years of experience and development. During manufacture only the very best materials are used to guarantee a long working life and minimal maintenance.
ECO heating
All heated tanks are heated by boilers with lowered flame combustion temperatures for clean combustion and low nitrogen oxide emissions. Boilers are equipped with durable burners that are controlled by digital combustion management to ensure economical functioning, easy operation and simple maintenance.
High efficiency pumps
Glasbeek industrial pumps are carefully selected to ensure high reliability even when working under harsh operating conditions. The pumps are equipped with frequency controls to adjust the speed of the motor. This matches the capacity and power of the pump to exact capacity needs. Up to 60% energy savings are possible thanks to the speed controller.
AUTO flushing system
Rinse water consumption is minimized by placing rinsing tanks in a cascade and using an automatic flushing system controlled by conductivity.
Comfort Control
The heated tanks can be automatically put into operation outside normal production hours. Ease of use can be further enhanced by using automatic level control, rinse water control, chemical dispenser systems, etc.
Automatic Start-Stop system
Pumps and fans are automatically and gradually turned on and off by using the production Start-Stop system. The start-stop system helps you to reduce energy and water consumption considerably.
Energy-saving air blasting zone
Blowing off excess water that is present on the product after pretreatment helps reduce the amount of energy consumed in the drying oven that is required to dry the product.
For each pretreatment plant we provide an appropriate solution for preparing water used in processing, wastewater treatment and water recycling.
PLC & Touch Screen
Advanced technology can be monitored on the touchscreen and controlled with an easy-to-operate PLC menu. Remote assistance using an Internet connection is fast and user friendly.
