ENGEL is introducing an extended portfolio of mould temperature control solutions designed to improve process reliability, reduce scrap and cut utility consumption in injection moulding. The offering spans a wide range of temperatures and flow rates, with a focus on halving cooling water use, achieving high throughput and deploying more robust water distribution systems based on ultrasonic sensing. The latest generation of e-flomo and eco-flomo is now specified for applications up to 160 °C, addressing the needs of sectors such as e-mobility and medical technology. Temperature control is a key lever for quality and productivity, and deviations in water supply or ambient conditions are a frequent cause of rejects and unplanned downtime. As temperature control can account for more than 40% of an injection moulding plant’s total energy consumption, ENGEL emphasises integrated monitoring close to the machine and full control integration, building on over 15 years of development. The company also presents the new e-flomo one for high and fluctuating cooling demands, as well as the eco-flomo XL for high-flow circuits and their combined use for single-circuit monitoring. The systems are intended to stabilise processes, highlight weak points, and lower water and energy usage, including under varying production loads.
Temperature control manifolds with ultrasonic sensing up to 160 °C
ENGEL has advanced its e-flomo and eco-flomo water distribution systems and is presenting a new generation at K 2025. To accommodate higher mould temperatures increasingly required by new materials, the devices are available for use up to 160 °C. At elevated temperatures, cooling water quality becomes more critical and conventional flow measurement can be inaccurate. The enhanced units are offered with ultrasonic sensors that enable contactless flow measurement. This approach increases robustness and reliability while maintaining precision, including at very low flow rates. Engel extends its established process stability and energy efficiency benefits to very high-temperature applications through this portfolio expansion.
e-flomo one for high and variable cooling water demand
The e-flomo one addresses applications with high cooling water consumption and high system availability requirements, notably in packaging. Moulds in such installations are often supplied by central cooling circuits subject to pressure and flow fluctuations depending on production utilisation. The e-flomo one compensates for these fluctuations within seconds, supporting consistent processes and reduced scrap. It controls both flow rate and temperature differential directly at the main cooling water inlet of the injection moulding machine. According to ENGEL, this can reduce cooling water consumption by up to 50%, representing potential savings of up to €10,000 per year. The device is designed for moulds with high cooling water demand and supports flow rates up to 600 l/min.

eco-flomo XL and e-flomo one used together
The eco-flomo XL has been deployed in the packaging sector as a high-performance option for moulds and production systems with flow rates up to 100 l/min per cooling circuit. To further increase process reliability and energy efficiency, ENGEL offers the combination of eco-flomo XL with the e-flomo one. This arrangement provides precise single-circuit monitoring for maximum process consistency, while the e-flomo one maintains a constant flow rate to optimise cooling performance and stabilise the overall injection moulding process.
Reduces pressure losses and improves energy efficiency: With flow rates of up to 100 l/min per circuit, the eco-flomo XL ensures maximum process reliability and prevents temperature fluctuations.
Integration and availability
The temperature control systems are fully integrated into the machine control, which reduces operator workload and the potential for error. The portfolio is positioned to prevent scrap, surface process issues quickly and improve process stability while significantly reducing water and energy consumption, including under fluctuating ambient conditions. ENGEL plans to present these solutions at K 2025 in Düsseldorf, Hall 15, stands B42 and C58.
