All td finishing Conveyorised powder coating systems are supplied with modulating Gas and Air Burners.  These burners are fitted to our Drying Ovens, Powder Curing Ovens, as well any heated stages of the spray pre-treatment systems.

We understand the importance of efficiency in heated processes as well as the roll plant design has on optimising temperature uniformity.  Accurate temperature control is a key aspect in achieving tight tolerances in temperature and fully modulating systems allow for much greater control over traditional “High-low” burners.   


Latest APL Technology

The Burners utilise the latest ‘Air Pressure Lead’ (APL) monoblock gas valve technology. Changes in process heat demand are transmitted to the burner by a modulating signal connected to a motor speed controller which varies the speed of the burner combustion air fan and increases or decreases the burner windbox differential air pressure.

This means the package gas burners offer flexible, high turndown control for process heating applications.  Giving minimum running consumption during production, but with high-power output available on demand as and when is required, particularly during system start-up.  td finishing can offer 24/7 timers for automated system heat up prior to commencement of manufacturing operations.


Safety is a Key Feature

Safety is another key feature of our package-gas modulating burners and the as such the oven burners comprise a burner windbox, combustion air fan, a compact monoblock air / gas valve gas train and gas burner controls, including the combustion air fan motor speed controller, mounted within a control panel.  For ease of access during use all burners can be supplied with a remote panel where required.

Standard control items include a burner controller ignition transformer and differential air pressure switch. Two 3-way air valves perform safety checks on the air pressure switch in both open and closed modes each time the burner fires, allowing the burners independent operation of the combustion air fan in conjunction with oven /dryer main recirculation fans.


Individual Control

On our Pretreatment systems you’ll find a modular immersion tube burner which includes a cylindrical burner assembly built to withstand typical tank heating operating environments, a compact monoblock gas valve train, burner controls mounted in a protective control box, exhaust damper and an exhaust fan which can be coupled to multiple burner installations all the while maintaining individual control.  The burner fires through a submersed stainless steel burner tube designed to give optimum surface area and heat transfer through the process.
