Intry Verified receipt
Is the Intry Refrigerant Blend Top-Off Check accurate?
The provenance receipt for the Intry Refrigerant Blend Top-Off Check: the exact authority its values derive from, the edition they are keyed to, who has final say, and what our automated checks hold them against, rebuilt from their cited source.
Short answer: Every figure an Intry calculator computes comes from a locked source module, not hand-typed. 28314 automated checks re-derive and source-check the numbers against the refrigerant manufacturer's datasheet and leak-recharge data it was derived from before each deploy. This is our own deterministic gate, not a third-party audit. The per-tool receipt is public at https://www.intrysys.com/verified.
The receipt
- Calculated from
- Chemours Opteon and Freon product information sheets · Chemours temperature-glide bulletin and the 407C/407A bulletin C-11261 · Chemours Freon 407C Retrofit Guidelines C-11107, Influence of Leak/Recharge on Performance · Chemours Opteon FAQ C-10677; Honeywell Solstice N40 and N15 data sheets · 40 CFR 84.106(b) · This site's CoolProp 8.0.0 run (2026-09-07), for the R-450A glide check only. Reused verbatim from the locked engine, never re-written for this page.
- Checked
- Before any release, an automated check rebuilds the calculated figures from the locked engine that produces them and holds each one against the source it cites, so a number answers to its source and not merely to itself. As of the current build that suite holds 28314 checks, and this page has to clear them too. This is our own deterministic gate, not a third-party audit.
- Runnable
- A reference engine behind the published numbers on this site. Runnable access is offered on the calculators exposed at the Intry MCP endpoint.
- Final say
- The refrigerant manufacturer and the equipment manufacturer have final say on charging a blend after a leak; a Section 608-certified technician does the work.
