Infragas technology for high temperatures
INFRAGAS radiant burners RHT are infrared pre-mix gas systems able to reach a surface temperature up to 950°C.
Radiant High Temperature heaters are a safe and reliable source of heat generated by a gas combustion (Natural Gas or Propane) and transmitted through infrared rays in short wavelength. The infrared energy emitted by the RHT radiant surface is absorbed by the exposed materials fast and uniformly. They are specific for thermal processes that require high temperatures or rapid curing time (for example pre-heating process on metal parts such as moulds, powder melting and many other applications).
Frame and body of the RHT are totally made with specific stainless steel for high temperature working conditions. Each burner is equipped with a control and pre-mix system with a calibrated mixture of air/gas.
The RHT operate in a range of power from 100% to 50% and are ready to be installed.
Infragas manufactures two RHT versions:
STANDING-ALONE, each unit is independent;
REMOTIZED, for connection to a main PLC (Programmable Logic Controller).
With reference to the environment respect, it is important to take in consideration that the microflame combustion on the metal surface fibre emits extremely low levels of NOX, CO and unburned.
