Product Name CHAIN RAIL AND MESH BELT COMBINATION SMD HOT AIR REFLOW OVEN
  Product No. WJ-35RHA
Features:
- Equipped PCB jam alarming device to give photoelectric sensor alarm
- Equipped extreme and low temperature alarm signals and emergency shut down device to ensure the safety
- Equipped Pneumatic auto cover opening device to clean residues and be able to check the conveying systems.
- As the system was shut down, cooling system device will keep detecting the temperature of the machine until the temperate was cooled down to protect the system from damaged by high temperature.
- Special reinforced rail in segmented design that leaves adequate gap/clearance between sections of rail and that holds adequate rail straightness even under high temperature, the parallel degree maintains within 1.0mm.
- Enhanced power saving function: Energy-preserver could save energy and power consumption, it takes only one third boost power in reflow operation.
- Independent circuit space in each zone and by means of specific turbulent heat-collecting plate, compulsory stabilized hot air convection is achieved between each compartment inside the machine the temperature is dirstrbuted to each zone uniformly to eliminate shade and sheltering effect and overcome the annoyance of uneven heating.

  Product Name SMD MESH BELT TYPE(COMPACT)
  Product No. WJ-35EHA
  Features:  
  The device is designed to small amount and variety of procreation, and limited working space. Lessening design of whole machine is depended on standard mode to narrow.

  Product Name SMD MESH BELT TYPE(ECONOMICAL)
  Product No. WJ-40MHA
Features:
- Hot air speed control adapted to a 32-bit digital speed controllers of extra-low noise level that allows free shiftless speed adjustment.
- PID temperature controller could detect temperature deviation automatically and keep the temerature in various zones within ± 1℃.
- Mesh-belt conveyor system made of SUS heat-resistant stainless steel, and mesh-belt tensioning device adapted a lateral lead screw adjust system for high performance.
- MHA series adapted hot air suction circulation design that imposes hot air to flow reciprocally inside of furnace by supplying hot air at a fixed speed or RPM that could overcomes the flaw resulted from uneven heating.
- UPS safety device ensures all PCB discharged from the furnace automatically upon any power disconnection, failure or pause causing PCB to remain inside of the furnace.
