6 STAGES PRE-TREATMENT TUNEL:

Description:
The pre-treatment tunnel is made of a set of rectangular section elements
within which occur the different treatment stages.
TanI‹s holding each stage’s appropriate solution, are placed below the spraying tunneL The solution is then recycled through the spraying ramps’ nozzes by convenienty sized centrifuga pumps. Pressure gauges and flow va|ves are installed in the piping between the pumps and the ramps manifolds,
The degreasing solution is held into two separate adjacent tanks, one overflowing into the other, so that the uItra*iItration unit draws from the first (dirtier) tank and sends the ultra filtrate back into the second (cleaner) one which overflows into the first,
The spraying ramp areas are divided one from the other by appropriately designed partitions so that contamination from the different solutions may be minimized.
Where required, solutions are kept warm by external tube and mantle heat
cxchang‹›r5 running on hot water.
Steut sheet insulation panels, with rock wool filling, line the warm tanks, as well as the upper part of the tunnel, from the outside.
Fumes are exhausted through fan operated hoods placed at the tunnel’s entry and exit points.
Awalkway is placed inside the tunnel all along its length for ramps inspection and maintcnance.
Lamps are placed outside the tunnel rooftop for maintenance,

proof membrane or butterfly adjustment valves. AISI 304 stainless steel centrifugal solution recycling pumps. Warm tanks and the uoper part of the tunnel are insulated with panels made of 1,2 mm thick galvanized steel sheet filled with 50mm thick rock

H20 DEMI PLANT:

Description:
A demi plant is required to supply the necessary replenishment water with de ionised water
when re-cycling the same degreasing solution continuously. This prevents the build up of unwanted salts in the process tanks.
The continuous waters washing will be recycled and recovered in closed cycle
by a ion exchange plant.
The water is sent to a suitable pumping tank, and subsequently to the resin columns.
The demineralised water flows in a tank, from which it is sent to the
utilizations.
The eluted of the regeneration products will be treated in the cleaning section.

Delivery: :3-4m³/h Water specificati on: < 5 pS

Drying Oven:

Description:
The oven is at floor level with air curtain protected entry and exit. It is made of a main structure of steel profiles, supporting both the overheadconveyor as well as the side panels, and of one heat exchanger at its side. The panels are made of two steel sheets with in between a layer of high insulating capacity rock wool. In order to reduce dissipation, the contact points between the inside sheet and the outside one are minimal.
An even temperature distribution inside the oven is guaranteed by a set of adjustable hot air vents in the oven floor through which flows the hot air recycled by the fans placed on the oven temperature. The heat generators are fired with methane gas.
Dimensions: Outside width=3.000 + 1.100 mm. approx.
Outside length=16.300 mm. approx.
Outside height=3.500 mm. approx.
Features:
Main structure made of steel sections painted with a layer of bottom paint. Insulated panels, 150 mm thick, with 1,2 mm thick outside galvanized teel sheet 1,2 mm thick galvanized steel sheet air vents.

Powder Curing Oven:

Description:
This is an overhead oven with pre chamber bell type. It is made of a main frame of steel sections, with two heat exchangers located under the oven, supporting both the conveyor and the insulated The panels are made of a sandwich of steel sheets with in between a layer of thick insulating rockwool filling. The contact points between the outside and inside sheets are minimal to reduce heat losses. The indirect heat generator burners are fired with methane gas. Fans located on the generators recycled the hot air to the oven and back. Adjustable air vents on the oven floor assure an even air temperature. Temperature adjustment is given by devices placed in the control panel.
Dimensions: Outside width=7500 mm. approx.
Outside length=13500 + 3000 mm. approx.
Outside height=6000 mm. approx.
Features:
Main structure made of steel sections painted with a layer of bottom paint. Insulated panels, 150 mm thick, with 1,2 mm thick outside galvanized steel sheet. steel sheet.

Main Electrical panel:

Description:
The panel is made of a set of steel cabinets containing all the electrical equipment need to run the plant properly.
As stated by CE norms, each motor is equipped with its own thermal breaker,
rem one switches, auxiliary relays, ON lamp, push buttons and dials.
Motors with a power lower than 11 kW shall be started directly, whilst those with a power higher than 11 kW shall be started with a Delta/Star con Section.
The panel door sha]] contain the main power switch with mechanical door release, all lamps, dials, the burner heat adjustment displays adjustment dials.
An S7 SIEMENS PLC with an interfaced touch screen panel is provided to run the overhead conveyor autom atically and the bridge cranes. The touch screen panel not onIy displays the whole plant but it is also needed to operate the plant manually if required. A MODEM is also added for remote plant operation and control.
Dimensions: Outside width=600mm.
Outside length=1200 mm.
Outside height=2000 mm.
Technical data: Power supply: 380 V 50 Hz Three phase + N
Installed power: approx 80 kW. - Auxiliaries 24 V
Make: Cabinet made of painted steel sheets. IP54 protection

HOT WATER BOILER:

Description:
To heat the tanks of the pre-treatment tunnel there is one boiler for hot water, RIELLO inversion flame with methane gas burner. All the necessary equipment such as re cycling pump, expansion vessel, safety valve, etc are also included in the supply.
