3. Metal Fiber Infrared Gas Heating System
PYROprecision™ | MFB Dual-Radiant™ Burner Configuration
The heating system features 7 PYROprecision™ Metal Fiber Infrared Gas Burners, utilizing IR-RED® FLAME combustion technology.
Combustion takes place within the porous structure of the metal fiber material, heating the burner surface until it glows red-orange and emits a portion of its thermal energy as infrared radiation. This technology delivers high-intensity radiant heat for continuous industrial heating applications.

4. HEATwave™ Temperature Control Cabinet | Model PP CTRL04P-1-7
The HEATwave™ PP CTRL04P-1-7 control system integrates AX-Flow™ Linear Gas Flow Control Technology to continuously modulate gas flow to all 7 infrared burners, enabling smooth and precise adjustment of radiant heat output to meet specific production process requirements.
AX-Flow Linear Gas Flow Control
Developed by PP Systems Co., Ltd. in Thailand since 2018, AX-Flow is a proprietary gas flow control valve technology under the HEATwave™ brand, engineered for industrial Venturi gas burner systems. It provides precise heat output control, minimizes temperature fluctuations, and supports a wide range of heating power adjustments.
AX-Flow continuously modulates gas flow by precisely adjusting valve position in response to 0–10 VDC or 4–20 mA analog signals from the temperature controller. This enables smooth, fine-tuned burner output control, unlike conventional ON/OFF or HIGH/LOW systems that regulate heat through intermittent burner operation.
