KGW Isotherm KF54V-K16-Z / KF54V-K25-Z Complete Stainless Steel Cold Traps Manufacturer Datasheet
Original English manufacturer datasheet covering the corresponding model specifications, construction and configuration.
View resource →Product overview
KF54V complete sets use two-piece 1.4301 stainless-steel coldfingers with glass or stainless-steel Dewars. The KF NW50 body joint allows separate removal of the condensate chamber; vacuum-line connections are KF NW16 or KF NW25.
Key features
- Standard stainless steel 1.4301; 1.4404 is available on request.
- The two body sections connect through KF NW50 with a quick-release fastener for emptying and cleaning.
- In fixed installations, the lower condensate chamber can be removed without dismantling the upper line.
- Coldfinger pressure range extends to 10⁻⁶ mbar vacuum and up to 3 bar gauge pressure; this does not make the Dewar coolant space pressure-rated.
- 18 C glass and DSS 2000 stainless-steel Dewars provide different coolant volumes: 1.6 L and 1.2 L respectively.
- Additional 360/560 variants hold 300/450 ml of condensate; sets including a CO₂ basket have separate order numbers.

Applications
Condensation of moisture, solvents or gases and vacuum-pump protection in laboratory, medical, biotechnology and vacuum applications.
Selection guidance
Check external flange, condensate volume, Dewar material and coolant volume, then whether a CO₂ basket is needed. Distinguish the KF NW50 body joint from the KF NW16/NW25 line connections.
