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

In the case of a tunnel with overhead transport, the components are loaded in to small piececarrying jigs anchored to a chain which transports the pieces through the various stages of treatment: As the development of the conveyor necessarily has to be in a closed loop, loading and unloading can be indifferently separate or concentrated in a single station.
In both cases the conveyor can work by continuous movement or by positioned stops: this last option is suggested to have a positioned cleaning. It’s possible to take place single or multiple treatments like: cleaning, rinsing, passivation, protection, blowing, drying…… In order to follow the always different automotive industry requirements, Ceever produces small and compact machines with custom bilt transport system. According to the requirements of the customer in terms of cycle and production, the tunnel is made to measure in order to guarantee maximum efficiency and reduced consumption.
In addition it’s possible to have these optionals:
De-olier: usually included in the degreasing tanks, the de-olier divides the water from the oil (no emulsion) in order to increase the life of the cleaning solution. The circuit is composed by a pump(3) that aspirates from the equipment’s tank(4) by a divice that follows always the level(2) and send the liquid to the separation device(1).
From the separatin device the water come back to the tanks(4) and the oil goes in an external tank(5).
Filtrations: for special requirements it’s possible to install filters 1 to 100 microns retention. For these machines are usually installed bag filters(1) feeded by an indipendent pump(3) that aspires the liquid from the tank(4), press it in the filter(1) and resend it back in the tank(4).
Automatic water restoration: the continuous use of the heated equipment cause a water’s evaporation that reduce the water’s level inside the machine. In order to resolve this problem, it’s possible to assemble an automatic level restoration system.
Rinsing water control: in order to save, as much as possible, the rinsing water, it’s possible to install automatic valves controlled by PLC
Teleservice: it’s possible to install a modem that allows the remote control of the machine (in order to help the assistance) or in order to send SMS about machine state.
Remote controls: for big machines, it is often useful to have the controls far from the electrical pannel. For this reason it’s possible to install remoted control pannels.
