CUSTOM WIDE WEB SELF ADHESIVE COATER

Dryer:

The dryer will comprise one free standing, 2 zone, 6 metre long unit complete with supporting steelwork and designed to allow suitable headroom for the operator to obtain access from below.

To ensure the dryer operates within safe solvent levels, the unit is equipped with a two point solvent monitoring system, each utilising a type FFA (SNR671) sensor and it’s housing.
Each unit will monitor the solvent level in the exhaust duct of the relative zone and will sound an alarm when the level is approaching the alarm set-point.
Should the level continue to rise a further set-point will be reached which will automatically trigger a “machine shut-down” sequence.


To facilitate cleaning and threading the dryer will incorporate the following features.

i) Sliding panels in the underneath of the dryer.
ii) Tendency driven rollers in an ‘arch’ configuration with a non-stick coated finish mounted at approximately 1 metre pitch.
iii) Motorised threading chain mechanism.

The dryer will comprise of an insulated enclosure housing nozzled pressure chambers, recirculation fan unit, gas heaters with control valve and interconnecting ductwork.

Insulation panels 75mm thick are carried from the dryer body the access doors (hinged type) complete with locking handles. Panels will be powder coated in a colour to suit. Exhaust ports will be taken from the dryer and connected into a common manifold that will terminate at a centrifugal belt driven fan unit mounted adjacent to the dryer.
