Versatile Solutions for Fluid Systems

Our customers use Versapass™ fittings as the entryway or portal into fluid systems for dip tubes and probes. Whether these systems consist of reactors, tanks, vacuum chambers, process pipes, or tube systems, they usually have controlled and sealed environments internally. The system may require the addition of liquids and gasses during a process or experiment, the removal of fluid for sampling, and the measurement of specific variables such as temperature, PH, conductivity, or particle size via probes. Opening or exposing these systems to the outside surrounding environment for any of the preceding tasks is not an option, as it can compromise a process, operator safety, or both.

Versapass™ feeds through fittings to grip, hold, and seal probes or dip tubes repetitively along their effective length without damage, distortion, or leakage. They offer clean, pressure temperature rated, corrosion resistant, variable positioning insertion into these systems.

Versapass™ offers quality products that support the process of getting fluids added to, removed from, or monitored by measurement probes in a reactor, including products to do one or multiple tasks through a single reactor port. In many pilot or scale-up labs for example, throughout an experiment or “campaign”, additional solvent needs to be added into a sealed reactor along with the addition of an inert gas such as nitrogen to “blanket” the solvent and displace the air. Samples need to be removed from the reactor and transferred to a container or bottle for analysis. Probes are immersed inside the reactor, or used outside the reactor via a recirculation loop to monitor a process. Versapass™ allows the optimum placement of a probe or dip tube inside the reactor for all of these tasks.

Numerous conditions in a reactor can benefit the variable, repeatable, and even calibrated (with Versapass™ calibrated probes and dip tubes) insertion. Here are some examples;

• Evaluating the effectiveness of mixers inside the reactor at various points: as well as keeping probes and dip tubes from coming into contact with moving paddles.
• Sampling or measuring stratified or non-uniform batches
• Setting the ideal addition point above a liquid for efficient dispersion
• Compensating for changing fluid levels inside the reactor.
• Versatility in setting the placement of a spray ball or nozzle and lance for a CIP process
• Thermal mapping at various points
• Efficient gas diffusion into a liquid via sparging wand placement
• Setting the ideal supply and return points in a recirculation loop for outboard probes

A single Versapass fitting can accommodate any probe or dip tube for a given diameter for a wide variety of tasks. There are typically more tasks for a given development project than there are reactor ports to fixture the probes and dip tubes needed. Versapass multi-port fittings offer multiple feed-through fittings or port connections through a single reactor port. Below are product suggestions for a variety of tasks. This is not a complete list, and we invite our customers to share additional examples via the contact page.

The illustration below offers examples of how Versapass™ ersapass fittings can accommodate many different probes with variable immersion for monitoring PH, conductivity, particle size, or concentrations as well as temperature.
