Forced-Air Oven

Made in United States

Ships from United States

This series provides large bench or portable capacity. Take advantage of the ease, convenience and increased uniformity of the digital-control models.
The digital PID microprocessor provides not only ease of temperature setting, but temperature tracking and ramp & soak capability, allowing for the most demanding applications. Digitally controlled ovens use a 'J'-Type thermocouple and will hold set temperatures to within ±0.5°C, providing improved uniformity.
Although there are several different models and styles, all of the bench series ovens offer fan-forced air circulation, aluminized interiors, gasketed doors, adjustable 80-lb capacity shelves, high/low heat switch, rapid run-up and recovery times, and a 6-foot cord with plug.
All ovens are fully tested prior to shipment. These ovens are perfect for: preheating, thermal testing, self-batch processing, part drying, curing, baking, evaporating or dehydrating various media and soil aggregate, as well as many other applications. All units feature large work spaces and excellent portability.

Bench Ovens

Quincy Lab bench series ovens have been the workhorse in the industry for over 40 years. These time-tested bench ovens feature a redesigned chamber and air flow distribution system, improved cabinet insulation and an optional PID microprocessor temperature controller (ER MODELS).

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.

Features

Large bench or portable capacity: 7 and 10 cubic feet
All encompassing circular air flow
ER Model programmable PID control
80 lb capacity shelves
Rapid run-up and recovery
Full 18 month factory warranty
Maximum temperature options: 300°F (150°C), 450°F (235°C), or 550°F (288°C)

Construction

A virtual non-contact exterior to interior cabinet design and high-density industrial thermal fiber insulation greatly reduce thermal conductive transfer, resulting in greater energy efficiency and lower exterior wall temperatures. 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 exclusive Q-Lab "high-tech" bronze polyester. Large high-impact thermal plastic door handles always remain cool to the touch.
