In an industry where safety, efficiency and sustainability have become essential requirements, choosing the right faucet can make all the difference. In this interview with Francesco Balbo, a specialist from Idral's Technical Department, we delve into the role of thermostatic mixers in public and commercial environments. Particular attention is dedicated to the TERMO-TEMPO cartridge, a technological solution that combines temperature regulation and water supply time in a single compact component.
What exactly is a thermostatic mixer and how does it work compared to a traditional mixer?
"The task of the thermostatic mixer is to keep the water temperature stable, regardless of pressure or flow rate variations in the water mains. Unlike traditional mixers, where you have to manually adjust the temperature each time, the thermostatic mixer does everything automatically thanks to an internal thermostatic valve. This guarantees maximum comfort and above all safety, because it prevents sudden scalds in the event of pressure drops or interruptions to the cold water supply."
Are there Idral models specifically designed for high-traffic environments or healthcare facilities?
"Absolutely. At Idral we offer a wide and versatile range designed to meet installation needs even in the most demanding contexts, such as sanitary facilities and high traffic environments. By 'high traffic' we mean those places where the use of devices is frequent and continuous over time, such as hospitals, schools, gyms, campsites or large accommodation facilities. Some concrete examples of our range are the 900.12, 900.35 and 900.42 models, which are also available in a timed thermostatic version. These products combine robustness, advanced functionality and maximum safety for the end user."
Idral has introduced a revolutionary innovation: the TERMO-TEMPO cartridge. Can you explain what this is and how it has extended the versatility of the thermostatic tap, making it suitable even for compact installations such as washbasin fittings?
"The TERMO-TEMPO cartridge is an innovation developed by our technical team: for the first time, we have succeeded in integrating both the thermostatic and timed function in a single compact cartridge. This means that the same device automatically regulates the water temperature and limits the duration of the flow. The advantage is twofold: on the one hand, maximum safety is guaranteed, avoiding scalding; on the other hand, consumption is optimised, reducing waste."
What are the main practical advantages of a compact solution like this for basin and shower, compared to a system with separate devices?
"One of the main advantages of this compact solution is the ease of installation: having only one integrated component instead of two separate ones reduces installation time and costs. In addition, the design is cleaner and more essential, making it easier to fit into modern architectural contexts. From an operational point of view, maintenance is easier and costs potentially lower, as the system is less complex and more robust."
How much can you save in terms of water and energy consumption with an Idral thermostatic mixer?
"On average, significant water and energy savings can be achieved. According to studies conducted by Idral on the use of timed taps, savings can be up to 70% compared to traditional mixers, thanks to the precise control of the flow and the reduction of waste. When the timed function is combined with the thermostatic function, efficiency is also amplified in energy terms: less water used means less energy used to heat it. In projects where tens or hundreds of taps are installed, such as in sports centres, the impact on consumption also becomes very significant in economic terms."
From a design point of view, how can an architect integrate these taps into the concept of a modern, sustainable bathroom?
"The fact that they are safe and minimal in design makes them perfect for contemporary projects. In addition, they meet the requirements of accessibility, hygiene and safety regulations. Idral also offers technical support and personalised advice to designers to identify the most suitable solution according to the context of use."
And for the installer? Are there any special precautions?
"Yes, but nothing complicated, our devices are designed to be intuitive to install. The most common errors concern the failure to adjust the system pressure, the absence of filters at the water inlet and the use of unfiltered water to feed the mixer. However, following a few simple precautions, such as correct pressure balancing and protecting the system from impurities, can ensure optimal performance and a long product life."
How do you handle the maintenance of thermostatic mixers and what is their average lifetime?
"As far as routine cartridge maintenance is concerned, we recommend simple operations that can be carried out quickly: washing under running water, removing any impurities from the filters and lubricating the external seals. It is essential to use only silicone oil to ensure maximum compatibility with the materials and preserve the product's durability."
Can you tell us some examples of projects in which Idral taps have been installed and which highlight their effectiveness and versatility?
"Certainly.
A significant example is Elamus Spa, in Estonia, where Idral timed thermostatic mixers were installed for the showers. In this project, the aim was to offer a safe and comfortable user experience in a high-flow context, while maintaining a refined aesthetic.
A second interesting case is the L'Angioletto kindergarten in Turin, where progressive thermostatic taps for washbasins were chosen. In this educational context, the solution demonstrated its effectiveness in combining safety for children and ease of use, thus confirming the great versatility of the technology even in spaces with specific needs."
What can we expect from Idral in the coming years on this front?
"We will continue to invest in research and development. The aim is to extend this technology to other product lines and make it more and more accessible. We want to be a reference partner for those who design and realise efficient, safe, sustainable and beautiful public environments."
