The air volume of the blower (1 to 5) m ³ /min is adjustable.
Case dimensions: L820mm × W820mm × H1500mm
Blowtorch: Made of SUS304 material, self-made by our company.
The equipment structure consists of four major parts: the main control box, the blower device, the combustion support, and the combustion burner. The control box is portable.
Components, materials
The frame material is made of high-quality 304 stainless steel square tubes welded together. The control box material is (t=1.2mm) electrostatic steel plate, and the surface is treated with plastic spraying, making it more smooth and beautiful.
Control system
The control box adopts a relay control system. All electronic components are from leading domestic brands, which can better ensure the working performance and detection accuracy of the machine.
The temperature is controlled by an imported intelligent P.I.D thermostat (with automatic calculation function), high-precision PT100 thermocouple sensor and timer.
The equipment is equipped with the following safety protection devices: power overload protection, short circuit protection, control circuit overload protection, and ultra-high temperature protection.
Environmental usage conditions
There are no strong electromagnetic radiation sources nearby. Leave appropriate maintenance space around the equipment.
Temperature: Room temperature to 40℃.
Power supply requirement: AC220 (±10%) V/50HZ
The allowable voltage fluctuation range is 220V±10%.
Allowable frequency fluctuation range: 50Hz±1%.
When the equipment is not in operation, the ambient temperature should be maintained within +0 to 45℃
