Tunnel machine is considered the most traditional of washing/chemical treatment systems and is suitable for the cleaning and chemical treatment in general of details with simple shapes.
These machines are often used in the production lines of mechanical, automotive and aerospace companies for inter-process cleaning or for precision cleaning before assembling. Due to their own flexibility, tunnel equipments can be used for big and small productions.
Designed exclusively for water based spry cleaning, the treatment effect is based on the chemical, mechanical and termical action in order to insure good cleaning results.
The working principle is based on a linear movement of the parts through many phases of the treatment by continuous movement or by positioned stops in front of sprying jets for precision cleaning. During this movement the parts are involved by heated cleaning solution in high pressure.
In the case of a tunnel with a conveyor belt, the components are loaded on to a conveyor (with a fret mesh or bars) which conveys the pieces through the different stages of treatment: the development of the machine is in line
The stainless steel constructed tunnel conveyor washer incorporates one or more stages (washing, rinsing, drying,...). It works within an enclosed environment and degrease parts by spraying hot detergent solution (from 1 to 5% of detergent). The conveyor conveys the parts to be cleaned.
Applications:
Continuous washing
Washing of parts prior to assembly
Degreasing of parts between process
Washing according to cleanliness standards.
Characteristics
Modular construction
Stainless steel construction
Easy maintenance with easy access to chambers and tanks
