Liquid Cooled Oven icon

The BD-164 Model is a liquid-cooled laboratory oven capable of providing highly-stable, controlled, forced hot air circulation with rapid cooling using liquid LN2 or CO2. 

BD-100 Model Laboratory Ovens provide dry, air-circulated heat as an environmental testing condition. The ability to maintain precise temperatures occur with help from direct, drive-powered fans. 

CONSTRUCTION.  These liquid-cooled laboratory ovens feature a durable powder-coat finish over heavy-gauge steel, with stainless steel internal construction, and highly-efficient, low K factor, thermal insulation, this is built to last for many years.

CIRCULATION SYSTEM.  The performance level operates the internal workspace temperature from approximately -73°C to +220°C (approximately -100.4°F to +428°F). 

HEATING SYSTEM.  The oven features an industry-leading heating system equipped with low-watt density, ceramic core, nichrome heaters for accurate temperatures within ±0.5°C, as measured at the sensor.

RAPID COOLING.  Liquid cooling will bring a hot oven down to ambient conditions and as low as  -73°C (-100°F) in just a couple of minutes. Pull-down rates for the liquid cooling process are much faster than traditional test chamber mechanical refrigeration.

BD Series Laboratory Ovens are ideal for: 

  • aging
  • baking
  • curing
  • drying
  • sterilizing
  • and more.

If rapid cooling is not a requirement, take a look at the BD-900 Models. 

INSTRUMENTATION. The standard BD models have a manual-set digital controller. For more sophisticated test profiles, upgrade incorporates AESONE CONNECT creating a robust connected device giving you a standard and uniform interface that makes operation easier.

*Rise and pull-down rates calculated using IEC 60068-3-5 standard. Custom options available.

*Ideal ambient temperature conditions for test chambers is 23°C (73.4°F). The temperature and humidity range of assured performance is between 15°C and 25°C (59°F/77°F) and 30-50% relative humidity. Conditions outside this range may affect the performance of your test chamber and reduce the lifespan of the equipment.
