Cool Gauge RT-100 provides a level of cooling fluid control not yet seen in the industry to date. The Cool Gauge RT-100 is a robust, reliable & consistent way to Monitor the level of all common anti-freeze agents commonly used in process chilled water systems.
Cool Gauge Limited was founded with a clear vision: to leverage our extensive expertise as long-standing providers of Industrial Water Control Systems and Industrial Water Treatment Services. With decades of hands-on experience in the field, we have been dedicated to delivering high-quality solutions that enhance the performance and reliability of cooling systems. Our services have been instrumental in supporting process chilled water companies, industrial facilities, and end-users across the UK and Europe, ensuring optimal water treatment and control for a wide range of applications.
Over the years, we have consistently engaged with clients facing critical operational challenges related to water treatment in industrial cooling systems. One of the most pressing concerns has been the ability to accurately monitor all common anti-freeze levels in-line and on a continuous basis. This need became increasingly apparent as manufacturers and facility operators sought more advanced methods to prevent costly system failures caused by freeze bursts, widespread corrosion, and scaling issues—problems that can severely impact efficiency, safety, and long-term equipment reliability.
Recognising this industry-wide demand, we committed ourselves to developing an innovative, high-precision solution that would address these challenges head-on. The result of our efforts is the Cool Gauge RT-100, a state-of-the-art monitoring system that provides real-time, continuous tracking of anti-freeze concentrations. Built on our deep experience in the cooling industry, the RT-100 goes beyond meeting basic monitoring requirements—it revolutionizes the way industrial facilities manage cooling water conditions. With its advanced sensor technology, exceptional flexibility, and highly valuable data outputs, the RT-100 empowers users with actionable insights, enabling them to optimize system performance, reduce maintenance costs, and extend the lifespan of their equipment.
Anti-freeze formulations – or heat transfer fluid (HTF) used in low temperature chilled applications are fundamental to proper system operation. They play a vital role in the production processes of many manufacturing industries. However, the simplicity of the HTF’s primary task – to protect the system from freezing solid – often means the true value of the humble HTF is misunderstood and possibly underestimated.
This oversight can lead to costly damage, lost production, increased operating costs, the expense of replacement HTF costs and of course, environmental concerns if leaks go to drains or waterways.
The Cool Gauge RT-100 is a robust, reliable & consistent way to Monitor the level of all common anti-freeze agents commonly used in process chilled water systems such as:
The advanced 4-20mA & RS485 Modbus capabilities allow the RT-100 to gather data from adjustable set points and in turn automatically React to monitored conditions:
The fluids used to Protect cooling applications are often forgotten until problems occur. The advanced capabilities of the RT-100 help to protect your system through:
A clearly identified need for greater control and management of the site’s ‘production critical’ adiabatic cooling system. One of the key parameters to be kept under strict control is the HTF level, as, by monitoring and controlling the optimum HTF (inhibited) reserve, the system receives the necessary protection from freezing, corrosion and scale. Continuous collection of vital HTF data by Cool Gauge is delivered to the controller via Cool Gauge’s RS485 capability which effectively enables accurate dosage of the selected HTF to the system.
The HTF reserve is maintained accurately by adjustable high and low set-points in the controller. This data can also be seen by remote viewers in real-time, and, if necessary, alerts sent to operators via text or email if the set-points are breached. This facility warns operators of any impending problems such as drops in the HTF level due to leaks.
This graph shows data as viewed by operators after logging in to the cloud account. It can be seen that steady HTF conditions are maintained over the 13 month time-scale selected. Fluctuations, such as those seen if a manual shot dose of HTF is made, can be easily noted as a rise in the monitored level. The on-going HTF system average is shown in the grey box. Any historical data can also be seen by adjusting the start and finish dates in the cloud website.
