- Search or filter. Start with a model, manufacturer, supply requirement or mounting method. Active filter chips show what you have applied; remove one constraint when no records match.
- Select up to four products. The selection bar follows your choices. Opening a shared comparison uses the products in that link.
- Read conditions beside cooling capacity. Nominal values can be sorted together, including records marked “Test condition not published”. This is a numerical ordering of published values, not a performance ranking under equal conditions.
- Check differences and missing fields. “Not publicly available” means we do not have that published value. It does not establish the absence of a feature or certification.
- Share, print or export. Copy the comparison link, print the table or download CSV. The CSV keeps recorded units and includes field-level source evidence and dates; a downloaded copy will not update itself.
- Verify before purchasing. Open the manufacturer page and official document links. Check the precise configuration, dimensions, availability and terms directly.
No-JavaScript browsing: each product card has a comparison link, and comparison columns have ordinary remove links. Search, source access and CSV export work without scripts; interactive selection, unit switching and link-copy controls require JavaScript.
