Laboratory oven with forced convection

The Despatch LBB oven features a combination of horizontal and vertical airflow that offers excellent temperature uniformity at a moderate price.

It is recommended for a variety of laboratory and production applications including drying, curing, annealing and materials testing.

A top-mounted fan draws air through the heater coils and propels it back to the chamber through plenums in the side walls, resulting in consistent, uniform temperatures. Powerful open coil heating elements and a forward curved fan deliver faster heat-up rates and short processing times. Digital controls regulate temperatures within tight tolerances.

The LBB is designed and manufactured to provide years of dependable service. The fan and heater are top-mounted to prevent damage from spills. When spills do occur, the corrosion-resistant stainless steel interior and nickel plated shelves clean up easily. The motor is permanently lubricated and virtually maintenance free. And Despatch warrants the heater performance for a full five years – the best warranty in the industry.

Notes: Uniformity figures are based on a nine-point test conducted in an empty oven after stabilization period. Uniformity can vary slightly depending on unit and operating conditions. Time to temperature, recovery time, and temperature uniformity are based on 240V/60hz operation, with control panel on top. Actual results may vary slightly depending on unit configuration and operating conditions. Minimum operating temperature is based on 20ºC ambient temperature measured at the fresh air inlet with the exhaust air damper fully open. Maximum load capacity figures are only for standard configurations with controls on top. Specifications are subject to change without notice.
