Insect Rearing Chamber – IN03

The IN series chambers are designed with insect rearing as the primary application, but can be used for other research studies as well. Our IN series chambers are widely used among Drosophila and Mosquito researchers and offer state of the art technology for pursuing various research studies. The IN03 is an undercounter insect rearing chamber.

IN Series

The IN series was introduced in 2003 as the first commercially manufactured large capacity Peltier-cooled insect rearing chamber. Thousands of IN series insect rearing chambers are presently in use by research companies around the world. The advantages of these chambers for insect rearing include:

Reliable Cooling Redundancy

Each IN series chamber includes multiple, independent thermoelectric cooling units. The 7 year warranty on cooling components and the ability of our chambers to maintain temperature even if the chamber suffers multiple failures is unmatched by any other refrigeration-based chamber.


Due to the omission of all refrigeration equipment on these models, refrigeration technicians are not required during chamber servicing. Refrigerated insect rearing chambers are not only costly to service, but can require days to service properly. Nearly every component of thermoelectric-based chambers can be serviced within minutes with basic tools. For instance, the ultrasonic humidifier is capable of being removed and reinstalled in less than a minute and operates on non-hazardous 24 volts.

Superior Control and Uniformity

The optional ultrasonic humidification system provides excellent humidity control and avoids hot spots seen during chamber mapping of steam boiler equipped chambers. Thermoelectric cooling and automatic switching system from cooling to heating control provide consistent results throughout the available temperature range. Standard control at the sensor in these chambers is ±0.2°C and ±0.3%RH.

Greatly Reduced Direct and Indirect Energy Loads

The IN Series chambers utilize less energy than comparable insect rearing chambers and introduce less impact upon building cooling systems. This efficiency “dual benefit” allows our chambers to be located in spaces unsuitable for other chambers. Electrical energy savings by the IN Series vs. steam boiler equipped chambers can easily amount to hundreds or even thousands of dollars saved per year.

Wiely Proven, Non-Proprietary Controllers

Standard controllers for the IN Series are manufactured by Fuji Electric and are ideal for insect rearing chambers. Unlike many proprietary controllers, this controller is commercially available and proven in tens of thousands of installations. Standard functions include: autotuning, fuzzy logic, PID control, programmable alarms, calibration capability, offset capability, etc. A touchscreen control interface is optional. Other controller manufacturers are also supported (Watlow, Allen Bradley etc.)

Quiet Operation

The IN chambers utilize quiet and highly efficient DC fans. Locating these chambers in laboratory workspaces is a viable option.
