Despatch LAC High-Performance Bench-Top Oven

LAC bench-top mechanical convection ovens feature horizontal recirculating airflow and temperature uniformity and stability throughout the chamber. These ovens can be found in production and laboratory applications, such as curing, drying, sterilizing, aging, and other production procedures.

A high-volume fan circulates air throughout the stainless steel walls to create a constant horizontal airflow across all sections of the oven.
The result is a high-performance oven with temperatures up to 260°C (500°F). 

Horizontal airflow for ultimate temperature uniformity

The LAC uses horizontal recirculating airflow to ensure uniform temperatures throughout the oven. A high-volume fan circulates air through perforated, stainless steel walls to create a constant horizontal airflow across all sections of the oven.

Controls are easy to use

Improved controls are easy to use for both simple and complex applications. Single and multiple-temperature applications can be started with the push of a button. Multiple temperature operations are controlled by up to eight programs, with eight ramp and soak segments in each program.

Other features include a large, bright LED temperature display, a 32 character LCD status panel, and high-limit temperature protection.

Easy to clean and service

Cleaning is easy due to the scratch-resistant, baked enamel exterior, stainless steel interior, and smooth door surface. Servicing is easy due to convenient access to the heater and fan.

The reversible door can be mounted to open from either the left or right, permitting easy access when the oven is placed in a corner.

Superior quality

The Despatch LAC features a sturdy, welded, double-wall construction, three inches of glass fiber insulation, and heavy-duty gaskets.

Each oven receives a thorough quality and performance test before it is shipped. Heating elements carry a five-year warranty. All models are UL listed.
