Model SRI20P B.O.D. Thermoelectric Cooled Incubator, 19.3 cu. ft. (300 Bottle) capacity. Using innovative thermoelectric cooling technology, the SRI20P eliminates the need for a refrigeration compressor. This means that these units use 78% less power than alternative models and reduce room air conditioning loads by 75%. They also include 75-pound capacity shelves, which eliminates sagging.
SRIP incubators meet APHA specifications for Biochemical Oxygen Demand (BOD) and include a mechanical convection system to ensure even air distribution, a digital temperature set controller, over-temperature limit control, and a digital temperature display.
A one-amp interior outlet allows the use of shakers, stirrers, roller bottles, or other apparatus. Units are supplied with adjustable leveling feet.
SHEL LAB Low-Temperature Incubators are ideal for testing sewage, wastewater, and other low and room temperature applications. The SRI20P incubator is optimized for high-volume sample and drying applications.
The SRI20P includes:
  • P.I.D. Temperature Control
  • LED Display of SetPoint and Chamber Temperature
  • Interior Electrical Outlet
  • Door Ajar Alarm
  • Fan Assisted/Forced-Air Circulation
  • Aluminum Interior
  • 24 Month Limited Warranty

SRI20P Testimonial
The amazing temperature uniformity of the Shel Lab SRI20P allowed us to replace two compressor based BOD incubators with just this one unit. Previously, we had to use two units for our samples because the temperature uniformity spread was too large between the top and bottom shelves so that we could really only use the middle shelves. We definitely appreciate having more room in our lab. The slide out shelf is extremely convenient and the shelves in general are the sturdiest that I’ve seen in a BOD incubator. The energy savings* of the SRI20P is also a very important feature for me. Clean Water Services is a steward for public health, environmental protection and economic vitality. This goes hand-in-hand with the Shel Lab SRI20P’s energy efficiency and the reduction we will see in our lab’s air conditioning loads.
