This unit is used to preheat the upper and lower flexible fabrics to proper temperature.
The PU/phenolic chemical reaction at a suitable temperature, the process of heating the flexible fabric promotes the activation of the PU/phenolic R, making the fabric and the foam layer more firm and reliable.
The heating device uses a gas burner to heat the air and then blows the upper and lower layers of flexible fabrics.
Temperature sensors are installed on the upper and lower layers to collect the current temperature in real time and adjust it to be close to the target set value
