The BD-927 Model is a laboratory oven capable of providing highly-stable, controlled, forced hot air circulation. BD-927 Laboratory Ovens are standard laboratory ovens that provide dry, air-circulated heat as an environmental testing condition. The heating system  

CONSTRUCTION.  These 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 ability to maintain precise temperatures occur with help from direct, drive-powered fans. The performance level operates the internal workspace temperature from +38°C* to +220°C (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.

BD Series Laboratory Ovens are ideal for: 

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

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. Learn more in the Instrumentation Tab below.

With the popularity of rapid cooling, BD-927 Models have spawned a standard liquid-cooled model. Take a look at BD-100 Model Laboratory Ovens to incorporate liquid LN2 or CO2 cooling or cryogenic cooling into your laboratory oven.
