Spray Booths & Ovens
A range of standard modules or bespoke booths can be manufactured to individual customer requirements. All rigid construction.
Selection of filter media either pleated or bag filters
Compliant exhaust ducting and relevant silencers if required
Water wash booths
Fully welded tank and flange constructed in 2mm thick mild steel sheet and epoxy coated to prevent premature corrosion
Full booth width pre-filter to prevent contamination reaching pump and nozzles
Access to across width nozzle manifold to facilitate easy cleaning or maintenance
ABS pipework therefore eliminating corrosion
Water pumps lubricated by means of partial recycling of pumped liquid. Pump casing manufactured with quality cast iron Stainless steel impellers are fitted on standard versions.
All booths are fitted with belt driven axial fans and incorporate access hatches to blades
Design and Construction
All ovens are constructed through the use of module panels which are flat packed to site and bolted together. This method facilitates the build at difficult site locations.
The panels are manufactured from galvanised or stainless steel and sandwiched with high density RW5 mineral. Internal and external skins are connected by 100mm ties which minimise heat transfer through the walls.
The majority of the roof area is dedicated to explosion relief. By using angle frame construction and incorporating specific steels within the walls, handling systems can be supported. For example; conveyor or dead track runners.
All doors are designed so that dead track and runners can be accommodated, if necessary at a later stage. Various options exist for powered doors either using rod less air cylinders or geared motors. All operate with safety interlocks.
All direct fired ovens are designed with across width burner boxes (where height allows). Delivered and returned air is distributed across the entire length of the oven via the burner box through a multivane plug fan and scroll. By using a central control baffle within the main delivery duct and separate baffles throughout the ducts the oven can be balanced for even heat distribution (show photo).
A typical control box
User friendly digital temperature controller for set point and point temperature.
Digital process timer with countdown viewing
Separate high temp limit stat
End of process alarm (tones variable)
Burner lockout indicator and (alarm)
Cool down process timer set to allow oven to cool down for a pre-set time once burner is switched off
All burner programmers are built within the main control box (not located on the burner). This keeps it away from dust and heat environment and allows for easy diagnostics.
For box ovens and tunnel ovens the products of combustion and process are allowed to exhaust via blast gate baffles on the positive side of the multivane fan.
Air Curtain Systems
The criteria for all conveyorised ovens are potential heat losses from open apertures. Escaping displaced heat from within oven chamber is taken by a plug fan and scroll, hot air is then divided and delivered to a set of air knives and back into the oven. The set up is balanced for a partial bleed for products of combustion.
Sliding or hinged doors can be incorporated to oven frontal apertures which can be adjusted to suit work envelope, this minimising heat losses further.
The majority of service work undertaken is planned preventative maintenance and usually includes;
Burner appliance servicing and all related interlocks
Full flue analysis for products of combustion and room Co
Oven temperature grants for box and tunnel ovens
Conveyor drive and lubricating units and chain inspection
Cleaning motors and cooling cowls
LEV inspection and report for COSHH purposes
Appointments for assessments and familiarisation of plant are normally carried out prior to any service work being carried out. This initial visit is a good time to evaluate the plant for potential running cost reductions.
