IN FOCUS Standing the test of time S


b. c. d.


angamo has been manufacturing its Round Pattern Time Switches for over 65 years, and in that time has sold more than 11 million units. The Round Pattern Time Switch is trusted by installers for a wide variety of applications, not


just because of its reliability but its ease of use. The simple dial and levers make setting the switch up for daily fixed timings a breeze with no complicated menu options to navigate through. All Round Pattern Time Switches are also 20 Amp rated, providing a more robust switch than most other products on the market.


The switches are split into four categories: a.


Basic ‘black dial’ 24-hour time clock for simple on and off switching of up to 20A Standard 24-hour ‘red dial’ switch with added 100 hour battery reserve Solar Range - specially designed for lighting applications


Digital Range - the newest addition combines the high capacity and reliability of the electro- mechanical models but provides full 7 day programming.


Sangamo regularly hears from people with Round Pattern Time Switches still going strong after 40 and 50 years. When they eventually need a new switch, they reasonably assume, because of its age, that it might not be possible to get a direct like for like replacement. However, because the original design has never needed to be updated, an RPTS you buy today is completely interchangeable with one bought decades ago. The Sangamo range of specialist time switches and heating controls is distributed through Scolmore Group company, ESP.


Making a positive contribution: Nuaire switches to 100% recycled plastic in Drimaster-Eco Positive Input Ventilation (PIV) systems


T


he UK’s first ever Positive Input Ventilation (PIV) system – and still the market leader after more than 50 years - the Drimaster from Nuaire, has evolved once more! As from


October 2025, the Drimaster-Eco has swapped its casing from a virgin ABS plastic to a recycled plastic. The switch will result in a reduction of 167 tons of equivalent embodied carbon over the period of a year. PIV technology was invented by Nuaire in 1972 and was


recognised as a ground breaking, highly effective cure for condensation dampness and its associated problems – including harmful black mould - within residential properties. PIV systems draw fresh air present in the loft space, filter that air, then gently disperse it into the home via a central diffuser at a continuous rate. This creates a positive pressure within the home that forces stale, damp air and pollutants out through the natural leakage gaps found in every UK property, both old and new. Tried and tested, Drimaster PIV units are installed in over a million homes in the UK, and are particularly popular with social housing providers due to their cost-effectiveness, speedy install (Drimaster-Eco can be installed in a loft in less than an hour), longevity (many Nuaire Drimaster PIVs have been in operation for over 20 years), and non-disruptive nature for residents. Moving from the virgin ABS plastic to 100% recycled plastic will not impact the quality of the Nuaire Drimaster-Eco PIV units, although customers will notice a change in colour from the blue plastic to black. The units will continue to be made in Nuaire’s South Wales state-of-the-art manufacturing facility that covers over 71,000m2 and operates with minimal impact on the environment. Nuaire’s PIV technology and product range has continually evolved since the first iteration in 1972, with the latest incarnation – the Drimaster-Eco - using up to 20% less energy, meaning lower running and life cycle costs. In addition to the standard Drimaster-Eco, the Drimaster-Eco NOX is available which comes with two carbon cartridges which reduces NOX levels – a dangerous pollutant commonly caused by road traffic - within the home by up to 80%. Drimaster models are available with a 400W heating element fitted on the diffuser to temper the airflow should the temperature in the loft space drop below a set point, ensuring ultimate comfort in the home. For homes without lofts, the Flatmaster PIV unit is available. This latest product development comes on the back of Nuaire’s announcement of its switch to the


use of XCarb® low carbon-emissions recycled and renewably produced steel on many commercial units, which will directly result in a 68% reduction in CO2 emissions, and the use of recycled plastic for its ducting. As part of the Genuit Group, which has pledged to be net zero by 2050, Nuaire has set rigorous carbon reduction targets and, in 2024 alone, removed 2,000 tons of carbon from its product portfolio.
