Revised With the largest installed base of US-made in-line vertical ovens, Heller is a top choice for leading electronics manufacturers. Vertical in-line epoxy curing delivers immediate benefits, improving productivity, consistency, and floor space efficiency. Higher productivity with in-line processing — Eliminates manual loading/unloading of batch ovens and reduces idle time by removing the need for warm-up delays. Available in fully and semi-automated configurations. Improved process consistency — Continuous in-line operation prevents temperature variations caused by opening batch oven doors, while forced convection heating ensures uniform thermal profiles for better product quality. A 30-minute curing profile on the VCO 290 Vertical Curing Oven demonstrates exceptional temperature uniformity. Minimal floor space requirement — The vertical design maximizes space utilization. As cleanroom and factory floor allocation costs increase, vertical curing systems can run multi-hour cycles in as little as six square feet of floor area.
