What are "Green Systems"
WPT Green Systems is committed to the technological advancement of environmentally friendly autoclaves, as well as other industrial process equipment.
Our environmental goals include cutting energy consumption, lowering emissions, and reducing your companies’ carbon footprint, while increasing efficiency in gas fired thermal process equipment.
WPT Green Systems has advanced gas fired thermal process equipment through the development of more intelligent burner technologies and controls, and is an industrial leader in low and ultra-low NOx burners, heat recovery systems and hybrid burner technology.
Low and Ultra Low NOX Burner Systems
The traditional autoclave gas burner system uses mechanical valves and linkages to control the air to fuel ratio.
These systems do not account for the nonlinearity of mechanical components and cannot auto-adjust to accommodate a wide range of operation.
Our low and ultra-low NOx burner systems utilize a nozzle-mixing, medium velocity, low excess air burner, with precision air to gas control valves, and an intelligent ratio
controller to reduce emissions by up to 85% ppm and 99% CO ppm*.

Why Worry About NOx Emissions?
Nitrogen Oxide is a leading cause of greenhouse gases and photochemical smog, both of which effect the environment and the human body. The emissions of NOx can severely irritate lung conditions such as asthma and cause a reduction in lung function, as well.
Heat Recovery Systems
On most autoclave systems today the gas heating process takes place in a combustion system circulating hot air through the heating coil and then exhausting to atmosphere. By reintroducing the exhaust air back into the heating system it reduces the amount of energy required to heat the ambient air necessary to maintain the system process temperature.
This reduces fuel consumption of a gas burner by an average of 25% during ramp and 70% during soak per cure cycle.
