7. Operation
1. Cabinet Cooler
The Cabinet Cooler is factory set to deliver the most efficient cooling needed to
maintain a desired temperature inside an enclosure.
At 80psi (5.5 Bar), 10cfm (70% of 15 cfm, red generator) of cold air will exit from the
Cabinet Cooler providing 293 Watts (1,000 Btu) of Cooling.
The bladder valve acts as a pressure relief valve. This will automatically release air
from the enclosure maintaining approximately 8” water column (0.0199 Bar) positive
pressure inside the cabinet/panel.
2. Generators
The generators within the Cabinet Cooler control the air consumption and air flow. They
also influence the achievable temperatures.
The chart below shows achievable temperatures with different generators fitted.
Please note these are approximate temperatures and should only be used as a guide.
The Cabinet Cooler will perform differently when used in other environments.
