Source reading and conditions
Publisher qualitative legend: ++ very good suitability; + good suitability; 0 limited suitability; - no suitability. These categories are not measured values or percentages. Blank remarks are NOT_LISTED. Paste footnote markers remain visible; *) states cycle time more than 24 hours. A merged remark is marked SHARED_REMARK_NOT_INDEPENDENTLY_MAPPED.
- Versioned manufacturer catalog entries are neither tested customer performance nor an established current configuration.
- No installed-option, site-fit, process recipe, metered energy, current offer, Jintaijin equivalent or regulatory approval is established.
- Units, decimal punctuation, multiplicity, alternatives and conditional row bases remain literal; no cross-family scoring is calculated.
- The tunnel-diameter row has no explicit unit and is excluded. Bm³/h is not converted to Nm³/h; slash alternatives are not summed or reinterpreted as ranges. Turbine powers are not multiplied to infer system power. No blast result or explosion-protection approval is established.
Source and sample-review scope
Official THM brochure, 06/19, physical page 8, captured 2026-10-05.
Use this independent Walther Trowal reference to prepare a supplier and sample discussion. It does not establish Jintaijin supply, partnership, an equivalent product, current offers or a customer trial. Obtain a current specification and safety documentation, then define a real sample, part or liquid-stream objective, constraints and acceptance method. User annotations remain USER_RECORDED_NOT_VERIFIED. No mixing, dosing, compatibility, hygiene or wastewater-discharge approval follows from this page.

How should source symbols and missing remarks be read?
Publisher qualitative legend: ++ very good suitability; + good suitability; 0 limited suitability; - no suitability. These categories are not measured values or percentages. Blank remarks are NOT_LISTED. Paste footnote markers remain visible; *) states cycle time more than 24 hours. A merged remark is marked SHARED_REMARK_NOT_INDEPENDENTLY_MAPPED.
What source conditions must remain visible?
Versioned manufacturer catalog entries are neither tested customer performance nor an established current configuration. No installed-option, site-fit, process recipe, metered energy, current offer, Jintaijin equivalent or regulatory approval is established. Units, decimal punctuation, multiplicity, alternatives and conditional row bases remain literal; no cross-family scoring is calculated. The tunnel-diameter row has no explicit unit and is excluded. Bm³/h is not converted to Nm³/h; slash alternatives are not summed or reinterpreted as ranges. Turbine powers are not multiplied to infer system power. No blast result or explosion-protection approval is established.
Can these entries predict a process result or cost?
Versioned catalog values and symbols retain their source row bases; they are not measured trials or approved process settings. Symbols ++, +, 0 and - are qualitative; no numeric score, ranking or dosage is calculated. Descriptive pH is not a numeric range; media fill, batch volume and mass retain separate meanings. No part compatibility, finish, hygiene, discharge compliance, installed configuration or current offer is established. Independent Walther Trowal reference; Jintaijin supply, partnership and equivalence are not established. User annotations are not verified trials or customer facts.
What must the current supplier and sample review establish?
Use this independent Walther Trowal reference to prepare a supplier and sample discussion. It does not establish Jintaijin supply, partnership, an equivalent product, current offers or a customer trial. Obtain a current specification and safety documentation, then define a real sample, part or liquid-stream objective, constraints and acceptance method. User annotations remain USER_RECORDED_NOT_VERIFIED. No mixing, dosing, compatibility, hygiene or wastewater-discharge approval follows from this page.
