Dosing cabinets

Chemical dosing skids are pre-engineered modular systems that support pumps in applications where metered chemical dosing is required. A pre-engineered dosing skid is not only cost-effective, but easy to transport and quick to install. Here we look at the key benefits of dosing skids, and some important considerations to make when deciding their configuration.

When you strip everything back, a dosing skid is a series of pipes, valves, pumps, instrumentation and components configured to accurately dose a measured amount of chemical into a feedline with specific back pressure. Over the past seven years, Polymaster’s engineering team has reviewed every configuration of dosing skids its customers requested, and identified a common dosing pipework design across both a duty and a duty standby system.

However, even with a streamlined approach, no two applications are the same, and there are some important considerations to factor in when selecting a system that is going to best meet your needs.

Protection from the elements

If left unguarded from the elements your skid can risk deterioration and malfunction. It’s important to understand the environment that the skid is going to be placed in, and what conditions you need to guard against. To ensure that the skids are able to withstand whatever nature has to throw at it, Polymaster has designed an all-weather cabinet to house the skid. These cabinets are welded to the chemical tanks, with the factory-finished or standalone pipework connecting the tank to the dosing skid. This set-up always arrives at the location pre-assembled.

Chemical compatibility

Another important aspect to take note of is the chemicals that are going to be used in the configuration, and whether the skid is suited to those products. For example, Polymaster matches the chemical to the tanks polyethylene material, and ensures that compatible seals, valves and components are suited for the job.

Safety first

It’s important for a skid to have clear visibility and automatic shut-offs to ensure the safety of operators. Polymaster’s skids approach this issue by including perspex door panels on the double-door cabinets that house the pipework; to give the operator a clear line of sight to the dosing system.

There is also the option for an actuated valve to be fitted to the ‘in-fill’ pipe to the dosing system, which can automatically close the flow of chemicals in the event of a spill or rupture within the cabinet. Cabinet bunding allows the temporary containment of any spill keeping the operator and the environment safe. Polymaster also ensures that only tried and tested components are used within the skid.

In addition to the dosing skid, an in-loading truck fill panel can be mounted to the tank for filling compliance and added safety. Chemical tankers can connect and power up via the Polymaster Truck Fill Panel knowing that power will immediately shut off when the high level is reached. This eliminates the chance of overfilling and harming anyone on-site.

Avoiding hidden costs

Rather than dealing with multiple suppliers and having to coordinate installers on-site to connect the system, Polymaster provides a factory fitted, end-to-end solution. This both saves time and provides a single point of contact for any of the components within the skid.

Because Polymaster’s dosing skid is designed to suit a large range of applications, there is minimal wait time for a cost to get into your project budgets.
