How the calculator treats it
Built around a titanium heat exchanger. Manufacturer recommends sizing the pump from the complete plumbing system, not zero-head GPH.
Capacity basis: Manufacturer publishes 5,000 BTU/h. Penguin states standard chillers need at least 250 GPH measurable flow after system losses.
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.
