Gilson’s extensive and diverse selection of airflow convection laboratory ovens offers solid performance and efficiency. They come in both bench-top and floor-standing models and are suited for many different drying applications. Chamber sizes range from 0.7 to 78ft³ (20 to 2,210L), with maximum temperature ranges from 105º to 550ºF (41º to 290ºC). While most models are electric, some are available that operate with natural gas or LP.
Gilson offers two types of airflow convection for Laboratory models: gravity and forced-air, and most are forced-air convection. Forced-air uses internal fans to circulate air in the chamber, has better temperature uniformity, and is more efficient at removing moisture from samples. Gravity ovens use thermal airflow to distribute heat and can have variable temperature zones.
There are several factors to consider when determining which make and model will meet your needs:
- Temperature range
- Chamber capacity
- Gravity or forced-air convection
- Cabinet size that fits in the intended space

- Quincy Bench oven models are forced-air convection and offer an 11 or 17 shelf capacity. Models BO-355 & BO-355ER accommodate up to 17 shelves; all others can handle up to 11. Chamber capacity is from 6.6ft³ to 10.6ft³ with maximum temperature ranges from 300° to 550°F (149° to 288°C). Many models are also equipped with a digital controller. A stainless-steel interior option is available on select models.
- Despatch Electric models are available in Standard and Deluxe models and are forced-air convection with chamber sizes ranging from 2.3ft³ to 27.0ft³. Deluxe models have a maximum temperature of 500°F (260°C), microprocessor controllers, and offer better uniformity. Standard models have economical single set-point digital controllers, and 400°F (204°C) maximum temperature. All Despatch models come with two shelves and have a five-year warranty.
- Shel Lab® ovens use forced air and feature turbo blower-assisted mechanical convection. Available in Economy or Deluxe styles. The Economy Series units range in size from 1.7ft³ to 5.6ft³, have analog controllers, and a maximum temperature of 392°F (200°C). Deluxe models meet UL/CSA/CE requirements and range in size from 1.39ft³ to 27.5ft³ with a maximum temperature of 583°F (306°C).
- Quincy Lab features models with gravity or forced air convection. Gravity convection models come in sizes of 0.7 cubic feet to 3.0 cubic feet with a maximum temperature of 450°F (232°C). The forced-air units range from 0.6 cubic feet to 2.9 cubic feet, with a maximum temperature of 437°F (225°C).
- Superpave Heavy Duty is a forced-air convection model that has a maximum temperature of 450°F (232°C). Affordably priced, it complies with Superpave mix design requirements, has a stainless steel interior, and needs no special wiring.
- Large Cabinet offers extra-large capacity, double-door, and works on forced horizontal airflow and comes in both electric and gas. The chamber capacity styles available in this series are 46.9ft³, 58.3ft³, and 77.9ft³. The large cabinet styles come with a 400°F (204°C) or 550°F (288°C) temperature maximum.
- Budget Hi-Capacity offers affordable bench units that feature forced-air convection and efficient operation. They are available with double doors and stainless steel interiors and have a selection of 15.8ft³, 27ft³ or 36ft³ chamber capacities. The Budget Hi-Capacity models have a maximum temperature of 400°F (204°C).
- Low-Temperature Lab Ovens provide a digitally controlled maximum temperature of 210°F (99°C) or 225°F (107°C), ideal for drying, evaporating and testing.
- Peerless Gas is a four-deck model that uses gravity convection. It has 12.6ft³ total capacity with a temperature range of 250° to 550°F (120°—290°C) maximum. The four chambers make it ideal for efficient gas heat drying of large-volume samples. The included low-temperature system allows for the gentle drying of sensitive materials. This model can use natural or LP gas, a selection that must be specified when ordering.
- Air Drying is best used for fireproofing and for drying materials like coal and soils that require air drying at lower temperatures, this 30ft³ unit can be operated with unheated air circulation or at temperatures up to 105°F (41°C). Even with a lower maximum temperature, drying is quick and efficient due to the unit's high airflow.
