Capacity values are the RT fields printed in the supplied catalog. Model selection requires project-specific operating conditions and a current performance map.
Standards context: ANSI/AHRI 550/590 (I-P) — the rating method behind chiller capacity and efficiency figures, including the integrated and non-standard part-load values (IPLV, NPLV) that part-load claims are quoted against. Enclosure and drive fields are read against IEC 60529 — the IP code behind the enclosure rating in these fields, with the tests that verify each digit. The catalog fields on this page are supplied values, not a third-party rating to that standard; project performance is confirmed in writing.
