Eight-zone extended-width convection oven for group soldering of SMD components onto a PCB surface

Patented two-layer insulation system provides:
– safety (external covers of the furnace do not heat up above room temperature);
– save up to 40% of energy compared to similar models of furnaces;
The monitoring system ensures the stability of all processes;
Highly efficient heating system:
– principle of hot air from a variety of holes;
– principle of microcirculation of air in the heating zones up and down;
Two-section module with powerful ventilation and filters to remove exhaust air;
Highly efficient cooling system with powerful fans;
Powerful fans in heating zones with a long service life (made in Taiwan) providing:
– effective heat transfer;
– low thermal inertia;
– temperature adjustment in each zone with an accuracy of ± 1 °;
– fast heating to the set temperature (about 15 minutes);
– low level of vibration and noise;
Stainless steel transmission system to achieve:
– resistance to high temperatures;
– low level of wear and deformation;
– high level of rigidity.
