How the calculator treats it

Designed for exposed installations where an indoor-only aquarium/hydroponic chiller would be inappropriate.

Capacity basis: Outdoor-rated enclosure; 5,750 BTU/h published cooling capacity.

The engine applies a low-temperature/high-ambient capacity band rather than assuming the nameplate BTU remains exact under every condition. Internal chiller pressure drop is also represented as a range, so a hydraulic PASS is only strong when it survives that uncertainty.
