Case Study: Sierra Gold Nursery
Sutter County, CA
BioTherm Cooling and Heating System
When Sierra Gold Nursery decided to pursue a plant tissue culture project, they needed special rooms that could be precisely calibrated for humidity, temperature, and light. Delicate samples are expensive to cultivate, and the failure rate is unpredict- ably high. To control costs by controlling mortality, Sierra Gold needed to perfectly control the environment. BioTherm was already installing the heating solution in another project, so they asked, “Do you do cooling, too?”
The BioTherm Solution
BioTherm used high thermal-transfer StarFinTM to surround Sierra Gold’s acclimation chambers. During hot weather and when lights are running, cold water circulates within the StarFinTM, keeping the environment cool. When the seeds need more warmth, hot water flows through the same pipes.
How It Works
The boiler and chiller for all the acclima- tion chambers connect to valves above each chamber, connected to a control that monitors and controls temperature, humid- ity, and light.
