Features and Benefits

B.O.D. Incubator Features and Specs

Energy-Efficient B.O.D. Thermoelectric Cooled Incubators for Wastewater Testing

Designed with a Peltier cooling technology and an innovative microprocessor, B.O.D. Thermoelectric Cooled Incubators by Shel Lab use up to 71% less energy because eliminate the need for a refrigeration compressor. Units provide excellent temperature uniformity throughout the incubator chamber ensuring that samples are under stable temperature conditions regardless of where they are in the inner chamber. These B.O.D. incubators help water treatment plants meet American Public Health Association requirements during wastewater testing procedures.

Note: Model SRI20P received a testimonial from the Clean Water Services (a water resources management utility in Tualatin River Watershed) for the unit's "amazing temperature uniformity" and energy efficiency.
