How do glycols prevent freezing in water treatment?

As outside temperatures drop to below 0oC in the winter months, there is a risk that water recirculating in chilled systems will freeze. In order to prevent the water from freezing, it is often necessary to add an a glycol-based antifreeze. 

5 problems with closed circuit systems and how to solve them

The problems encountered in closed circuit systems are like those in open systems, such as scale and corrosion. However, the fixed volume of a closed system allows for water treatment products to be dosed at much higher levels than is possible in open systems, where water is constantly lost to drain.

How inhibitors prevent corrosion and scale in closed circuit systems

Closed circuit inhibitors are often referred to as corrosion inhibitors, but their function is considerably more complex than that. Our closed circuit inhibitors are indeed specifically formulated to inhibit corrosion, but equally important is their ability to prevent the build-up of scale and to stop the deposition of suspended solids (fouling).

How to calculate closed circuit system volumes

In our recent blog posts, we’ve looked at the various chemicals and standards related to closed circuit systems. In this blog post, we take a step back and consider one critical piece of information: how to calculate the correct dose of chemicals to be used in a closed system.

Closed-loop pre-treatment cleaning (CPC) in closed circuit systems

This is the sixth blog in our series on the BG29/2020 Pre-Commission Cleaning of Pipework Systems guidelines. Here we take an in-depth look at the closed-loop pre-treatment cleaning (CPC) procedures for closed circuit systems.

Revisions to microbiological test methods in the new BSRIA BG29 2020

In last week’s blog post, we gave an overview of the potential problems caused by microbiological growth in closed circuit systems. In this week’s blog post, the fifth in the series relating to BSRIA BG29 2020, we examine the main differences in microbiological test methods and specifications in the new standard in relation to the previous 2012 edition.
