Modular System

Widely used in high-cadence applications, the degreasing tunnel can be adapted according to the application and allows the integration of multiple modules for the successive treatment of parts.

• Spray degreasing modules
• Phosphating modules
• Cascade rinsing modules
• Passivation / anti-corrosion treatment modules
• Hot-air drying modules / Intensive vacuum drying

Adaptation to Parts to be Treated

For effective cleaning and drying, the usable dimensions of the tunnel are defined according to the geometry and size of the parts to be treated.

• Usable width from 100 to 9000 mm
• Usable height from 7 to 1200 mm

Belt Conveyor

For the treatment of multiple part references, especially in general industry sectors, the degreasing tunnel integrates a stainless steel mesh belt that accommodates a variety of parts.

• Driven by gear motor with torque limiter
• Adjustable guides
• Programmable movement speed

Chain Conveyor

Two stainless steel carrier chains with hollow links allow the movement of existing part-support pallets. Fed by a first conveyor at the tunnel entrance, a second at the exit ensures the return of pallets to the next operation.

• Detection sensors at the entrance
• Saturation sensor at the exit
• Continuous or step-by-step movement

Pallet Conveyor

Specific supports adapted to the parts to be cleaned are integrated into the tunnel conveyor. This type of conveyor allows:

• Ergonomic positioning of the parts
• Indexing for robotic loading
• Maintaining the part in position to optimize cleaning and drying

High-Cadence Cleaning

Continuous flow cleaning of parts meets the highest production cadences, especially in the automotive sector.

• Tunnel length according to cadence and required treatment time
• Multiple parallel transport lanes

Transport Loop

In the case of a standalone tunnel, a transport loop equipped with shuttles allows moving and grouping the loading and unloading stations, circulating pallets or baskets in a loop.

• Gravity roller conveyors
• Operator control consoles

Accessibility for Maintenance

To ensure optimal accessibility during maintenance operations, each module is equipped with a lid with a safety switch to access the chambers.

• Large lids over the tanks allow quick access to the filters.

Targeted Cleaning

Thanks to our experience with complex parts, WashTech has developed special devices integrated into the cleaning tunnel for focused mechanical action.

• Internal cleaning of railway bearing cages
• Particle cleaning through injection in small circuits

Highly Special Applications

WashTech’s DNA lies in adapting our machines to our customers’ specific cleaning challenges.

This gigantic tunnel, over 18 meters long and 8 meters wide, capable of cleaning more than four hundred different part references, is the perfect example.

Our engineering and production teams work together to provide you with the right solution for your part cleaning challenges.
