New Guide to PICVs

Marflow Hydronics, the specialist solution providers for the balancing, controlling and metering of water distribution systems in the HVAC industry, has launched a brand new 'Definitive Guide to Pressure Independent Control Valves'.
New Guide to PICVs
The aim of the guide is to provide understanding and knowledge to help anyone using the products, ensuring that systems are designed to optimise the best performance levels.

The guide describes the design and operation of Pressure Independent Control Valves (PICVs), explaining how they work, their operational limits and the control options available.

Martin Lowe, joint managing director at Marflow Hydronics, says, 'We get asked so many questions about PICVs and so we developed this guide to offer help and support to our customers. It's been written with them in mind. PICVs have so many great benefits and if designers use this guide it will help them make the most of all those benefits in their systems.'

The guide has been written in conjunction with Chris Parsloe, an independent consultant who previously worked for BSRIA and has great experience with pipe system operation.

Whitepaper tackles legionella risk

Low occupancy rates in commercial buildings could be leading to a ticking time bomb of water quality issues according to Guardian Water Treatment.

To help building owners take the right steps to prevent these issues, in particular legionella, the company has launched a new whitepaper – Locked down but not forgotten.

In the whitepaper, Guardian draws on its own data from over 30,000 samples taken from commercial buildings, predominantly in London, over a six-month period starting from April 2020 (when the first lockdown began).
