CSZ Solar Panel Test Chambers Provide
Up To 66% Energy Savings
Using CSZ’s patented Tundra® refrigeration system
provides the ability to test product down to -40°C with
a load and a single compressor where traditional test chambers
for solar panel testing require a cascade refrigeration system.
Documented energy savings of 47-66% were obtained by following
the test specifications below with CSZ test chambers and a
Fluke power monitoring system.

*Time based upon a chamber that meets that
max ramp rate requirements. Data compares the energy savings
of operating at 15HP cascade compared to a 10HP Tundra in
an empty chamber. Cost savings calculations based upon 13
cents per Kwh.
A total of $560 - $860
dollars can be saved
completing each of the above tests in a
CSZ chamber with Tundra system.
