DESPATCH

FORCED CONVECTION OVENS

DESPATCH LBB FORCED CONVECTION BENCH-TOP OVEN

LBB Oven 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.

Fast heat-up rates

Powerful open coil heating elements and a forward curved fan deliver faster heat-up rates and short processing times.

Precise digital controls

Digital controls regulate temperatures within tight tolerances. A 3/4" LED panel displays temperatures in large, bright, easy-to-read numbers. Temperatures can be reported in either Fahrenheit or Celsius.

Reliable, trouble-free performance

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.

Every LBB oven is UL and C-UL listed, and receives a thorough performance test before shipping.

Forced convection for excellent temperature uniformity

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.

Sturdy Shelves

Standard shelves handle up to 50 lbs.; reinforced shelves handle up to 200 lbs. All shelves are nickel plated for maximum durability and easy clean up. Built-in shelf supports make it easy to change shelf locations.

1. 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.

2. Minimum operating temperature is based on 20°C ambient temperature measured at fresh air inlet with exhaust air damper fully open.

3. Maximum load capacity figures are only for standard configurations with controls on top.

Note: Specifications are subject to change without notice.
