INSPIRED INNOVATION
u LAC High-Performance Oven
With horizontal airfl ow for ultimate
temperature uniformity
e LAC high-performance bench-top oven
uses horizontal recirculating air ow to ensure
EXHAUST
uniform temperatures throughout the oven.
A high-volume fan circulates air through
perforated, stainless steel walls to create a
constant horizontal air ow across all sections
of the oven. e result is proven reliability

in demanding production and laboratory
applications such as curing, drying, sterilizing,
aging and other process-critical procedures.

Advanced control. Protocol 3™ is a microprocessor-based temperature and
hi-limit controller with large LCD display and real time clock for auto start
capability. e LCD display shows temperature readings along with clear,
detailed information on oven status. Protocol 3™ features three operating
modes for quick and easy operation: Manual mode, Timer mode and Pro le
mode. e data-logging functionality enables reporting and analyzing and
data les can be exported via the controller’s USB port.
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. e reversible door can be
mounted to open from either the le or right, permitting
easy access when the oven is placed in a corner.

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. Minimum operating temperature and cooling times are based on 20°C ambient temperature measured at the fresh air inlet. Specifications are subject to change
without notice. If the existing specifications differ from yours, ask about our customizing capabilities.
