Advantages
Rated to 600 °C, the 3500 Series includes a durable stainless steel muffle and features an ultra-clean low-mass refractory heating chamber. Air, nitrogen, hydrogen, or a mixture of these atmospheres are available and maintained at extreme levels of purity in a muffle-contained environment. Distinctly unlike other furnaces, the SierraTherm 3500 Series is an energy efficient precision thermal processing system which provides unequaled performance by way of:
- Zone isolation and rapid quenching technologies allow precision definition of reflow phase peaks
- Three tiers of graded, power saving insulation reduces energy bills
- Innovative atmosphere distribution and management eliminates thermal shock
- Stable, unsurpassed temperature uniformity control ensures consistent process results
- Vigorous extraction of burn-off effluents across entire chamber width improves yields
- Integrated burn-off condensate entrapment / collection inhibits process contamination
- Computer controlled hydrogen system and redundant overtemperature protection ensure workplace safety
Included on the 3500 Series is the powerful and convenient Windows based MicroTherm PC Control Profiling and Monitoring System, developed and introduced by SierraTherm.
