Residual volume is the key dry break coupling metric that no one is talking about
What Exactly Is Residual Volume?
First things first: defining terms. “Residual volume” is the term used to describe the amount of chemicals that are exposed to the environment during the coupling & decoupling procedure. If excessive, it is also referred to as “spillage”.
Why Is Residual Volume so Important?
The main reason for choosing dry-disconnect couplings is to minimize product exposure and residual volume as much as possible. In many cases, minimizing the chemical residue is critically important for the purpose of protecting operators, as well as the environments they work in.
Choose your Couplers with Care
Different couplers and other connection types produce different levels of residual volume. Among these, the dry-disconnect couplers are the “driest,” meaning their residual volume levels are the lowest. Testing carried out by Limbol Dynamics suggests that the SAS has the lowest residual volume coupler in the industry.
Back to the Basics
Other coupling manufacturers frequently site different metrics for comparison and simply fail to mention the residual volume: transfer rates, weight, materials, transfer pressures, and many other facets are all interesting comparative figures. But remember that for dry-disconnect couplers, the most important characteristic is the minimized residual volume.
SAS couplers are specifically designed to minimize spillage and maximize productivity and safety.
