The Despatch LAC1-67 is an electric light assembly oven with mechanical convection heating for industrial thermal processing. This 6.6 cu. ft. chamber delivers precise temperature control from ambient +15°C to 300°C (27°F to 572°F), with a maximum operating temperature of 260°C (500°F). Forced-air convection with horizontal recirculating airflow ensures uniform heat distribution across the work load. The oven achieves ±1°C temperature uniformity at 100°C and ±0.5°C repeatability, making it suitable for drying, curing, and heat-treating applications demanding tight thermal stability.
