UK: The 31 m by 9 m paint spray booth oven built to accommodate rail vehicles at Hitachi Rail’s Newton Aycliffe rolling stock plant has been designed by Junair Spraybooths to optimise running costs while complying with safety requirements.
The iSystem touch control is pre-programmed with bake cycles and a list of coatings, ensuring the most efficient cure profile is automatically used and paint jobs are not over-cured or under-cured. This also balances the air pressure within the cabin to ensure compliance with safety regulations.
Two Junair pneumatically powered Alfa-Lifts are fitted inside the spray booth to provide access to all areas of a vehicle’s painted surfaces. The controls are inside the cage, with three levers allowing the operator to manoeuvre the platform on three axes to provide the optimal working position.
The spray booth has 32 Junair QADs auxiliary air movement towers designed to improve drying times by agitating air during flash-off and cure cycles, with automatic variable speed drives adjusting the airflow to suit the process. The full airflow rate is only required for spraying, and all other activities can be carried out with reduced airflow to lower running costs.
The fuel saver mode provides full fresh air intake for paint application, and automatically switches to recirculation when in idle, loading, preparation, flash off and bake modes, thus reducing air heating costs.
There are high, mid and low level LED lighting within the booth, and a bespoke paint mix room and ventilated mixing bench were also supplied.
