Features
The maximum hot air temperature for the JRF4 Specification hot air furnace can be higher than 200℃. The maximum hot air temperature for JRF5 and JRF6 specs can be greater than 300℃ (for the special manufacturing furnace, the maximum temperature can be more than 500℃.) The temperature can be adjusted according to the demand.
Hot air furnace chimney height: for JRF4 spec, it is 3-5m and for JRF5 and JRF6 specs, they are 5-8m.
The fire-resistant layer on the internal wall at the low section of the furnace hearth begins at the furnace wall. The fire-resistant layer can be installed on site.
JRF6 Specification is the chain-furnace arrangement-Specification combustion device.
