Convection Reflow Oven

The Tornado convection reflow oven is a high performance reflow oven that provides outstanding thermal uniformity, excellent profile repeatability and a high coefficient of heat transfer ideal for lead-free soldering. The Tornado 5, Tornado 7 and Tornado 10 are available with 5, 7 or 10 vertical heating zones and include many of the standard features you would expect in higher priced ovens. The Tornado is virtually maintenance free with low nitrogen consumption and electrical usage to ensure maximum production uptime.
