Swagelok® Ammonia Sampler
The Swagelok ammonia sampler makes anhydrous ammonia sampling safer by minimizing operators’ exposure to liquid and vaporized ammonia. It also introduces consistency into the sampling operation, significantly expedites the sampling process, and eliminates the transportation of ammonia samples within the facility.
Contact a Sampling SpecialistAnhydrous ammonia is used in the production of fertilizers, plastics, textiles, petroleum, and more. To avoid ammonia stress corrosion cracking in storage tanks and product quality concerns, the product must be regularly sampled to verify a water content of 0.2% to 0.5%.
Swagelok’s closed-loop ammonia sampling unit is designed to remove the challenges inherent to traditional ammonia sample collection methods. The Swagelok ammonia sampler features:
- Closed-Sample Fixtures: Our ammonia sampler features closed-sample fixtures, which improve safety by limiting operator exposure and environmental impact from excess emissions. The design eliminates the need for extensive operator PPE. The glass front allows operators to visually monitor sample conditions. And it’s available in single- or dual-fixture designs.
- Prechilled Residue Tubes: Cold ammonia is used to create a cold bath to draw heat out of the fixture and residue tube, preventing aggressive boiling that threatens fill accuracy. The fill level of the cold bath is controlled using an elevated drain tube. It clears the supply line of older ammonia, resulting in a fresh sample. The ammonia fast loop chills the sampling valves while concentric tubes prechill the sample lines.
- Semiautomated Dispensing: A cap assembly is fitted to the residue tube to assist with the filling process. When filling the residue tube, the cap assembly assists in dispensing an accurate and precise sample size. The cap assembly seals on top of the residue tube and controls fill level. Any overflow empties into the cold bath, ensuring consistent sample size. 100 mL or 250 mL residue tube sizes are available.
- Single-Handle Operation: A single handle for controlling sampler function contributes to easier operation and helps prevent operator error. A geared mechanism controls four valves with a single handwheel, controlling “off,” “purge,” “chill,” and “sample” functions. Additional control valves can be provided for adjustability during commissioning and maintenance.
- Touch Screen Heater Controls: A touch screen interface is used to control all heater operation, improving consistency and preventing overheating. Easy-to-use, intuitive operator interface offers on-screen, step-by-step instructions for minimized operator confusion.
Each sampler is built to your specifications by experienced fluid systems technicians. All Swagelok ammonia samplers are rigorously tested and are backed by the Swagelok Limited Lifetime Warranty.
