TIME TESTED
Quincy Lab bench series ovens have been the workhorse in the industry for over 40 years. Now these timetested bench ovens are even better. A redesigned chamber and air flow distribution system, improved cabinet insulation and an optional PID microprocessor temperature controller (ER MODELS), make the bench series an easy choice for heating applications everywhere.
APPLICATION
Developed for the industrial lab, these rugged general-purpose ovens are perfect for: preheating, thermal testing, self-batch processing, part drying, curing, baking, evaporating, or dehydrating various media, soils or aggregate, and many other applications. All models feature large work spaces and excellent portability. They can be moved to the job, or stacked on one another to conserve space. Wherever thermal processing is needed, the bench series ovens bring year after year of troublee-free service and performance.
DESIGNED STANDARDS
A virtual non-contact exterior to interior cabinet design and highdensity industrial thermal fiber insulation greatly reduce thermal conductive transfer. That means greater energy efficiency and lower e x t e r i o r w a l l t e m p e r a t u r e s . Refinements in the air plenums and mixing chamber deliver an evenly heated horizontal circular flow of air for rapid heat to part transfer. A reliable quick-sensing hydraulic thermostat balances good temperature stability with recovery performance. Heavy-duty chrome plated wire shelves can support 80 lbs. and can be spaced on 1.5″ centers to provide up to 56 square feet of shelf surface (31-350). Cabinet exteriors are finished in our exclusive Q-Lab “high-tech” bronze polyester. Large high-impact thermal plastic door handles always remain cool to the touch.
