Economic contraction circulating hot air furnace STB-1810 / STB-2212 / STB-2816/2 / STB 1810/2 1810/2 dual-zone design TWO TEMPERATURE ZONE DESIGN 1, using the heat pipe within the budget cycle heating, low energy consumption long life, make sure the furnace temperature uniformity, double insulated curtain, reduce heat loss in order to achieve optimal contraction effect. 2, with several explicit temperature furnace temperature can be precisely adjusted, the transmission speed can be adjusted to ensure the stability and quality of the contraction effect of equipment operation. 3. Activities rotation roller conveyor chains, using solid roller, outsourcing high temperature silicone casing, can bear the weight of the object is not deformed, effective dust, durable (optional Teflon mesh belt). 4, automatic shutdown feature allows the device when the oven temperature down to 70 ℃, automatically cut off the power, wait for cool down time saving, but also to ensure the normal life of the equipment. 5, the electrical components are used well-known brand, to ensure the stability and accuracy of the device 6, the furnace can be used with different products of high height adjustment, easy to operate.
