The Thermal Image and Graph show the high degree of temperature control from the Gas Pulse principal. At Low Fire (0%) the average surface temperature of the heater is 300-350 F. (149-177 C.), while at High Fire (100%), the average temperature is 850-900 F. (454-482 C.) depending on heater orientation and position in an oven.
Gas pulse Technology uses electrically
actuated solenoid valves,
to cycle the gas supply between flow rates of 100% and 20%. Longevity and
reliability have been the hallmarks for this technology, and synchronizes very
well with the mechanics of the flameless oxidation process within Vulcan's
patented catalytic heaters. By alternating between the high and low flow rates,
the entire depth of catalyst is used, ensuring an even heat distribution across
the entire heater face at all percentage settings.
Control Panels
All control panels produced by Vulcan Catalytic
Systems are either UL and/or CE certified. Custom Designed or simple Electro-Machanical -see video guided tour of typical panel.
Zoning with Gas Pulse Technology
Flameless Catalytic heating which has
brought energy cost savings to numerous thermo formers and paint finishers, now
has a well proven method of control – Gas Pulse System (GPS).
The GPS unit is simple, cost effective and
offers the option of multi zone configuration, permitting accurate and
repeatable heating profiles for the catalytic heating system. Vulcan has
pioneered Gas Pulse Technology, having installed many hundreds in both the
finishing and thermo forming industries to control catalytic heaters. Typical
gas industrial control valves, are totally unsuitable for controlling catalytic
heaters. GPS has been proven to save gas consumption over other industry
control valves.
Controlling the GPS
Control of the GPS is via one of two
operator control types. For systems with less than five control zones, a simple
percentage timer may be used. For systems with a greater number of zones, a PLC
based control with an intuitive operator interface, offers the customer the best
solution for multi zone systems, with recipe storage, system diagnostics
functions and global increase / decrease of any heating profile.
