In today’s industrial environments, where uptime, precision, and sustainability are non-negotiable, cooling systems are under greater scrutiny than ever. From machine tools to electronics, laser systems to food packaging lines, reliable process and enclosure cooling is essential to operational continuity, particularly when high ambient temperatures, dense component layouts, or strict hygiene requirements are in play.
Enter Rittal’s Blue e+ chillers, a compact, high-efficiency liquid cooling solution designed to meet the evolving demands of modern manufacturing. Whether integrated into existing plant infrastructure or forming part of a digitalised value chain with EPLAN, these chillers are redefining what engineers can expect from industrial cooling.
Many modern industrial applications generate high heat loads that air cooling simply can’t handle efficiently. Liquid cooling offers superior thermal transfer, particularly for temperature-sensitive systems like high-speed spindles, laser equipment, welding robots, and control enclosures.
Rittal’s Blue e+ chillers build on this principle by delivering centralised, energy-efficient chilling of water-based cooling media allowing facilities to maintain precision control over both process and enclosure temperatures. The result? Greater stability, better product quality, and fewer interruptions.
With up to 70% energy savings, Blue e+ chillers set a new standard in sustainable performance. These efficiency gains are achieved through speed-regulated components and advanced DC inverter technology, ensuring that the system adapts its output to real-time cooling demand rather than running continuously at fixed speeds.
In addition, microchannel heat exchangers reduce refrigerant volumes by up to 40%, contributing to a lower carbon footprint and reducing the burden of environmental compliance.
From its multi-voltage capability to its compact modular design, the Blue e+ range is built for flexibility. Features include:
Temperature accuracy down to ±0.5 K for highly sensitive applications
Intuitive touchscreen control with multilingual support (21 languages pre-installed)
IoT readiness, including web-based diagnostics, real-time monitoring, and integration via the Rittal Smart Service platform
Plug-and-play commissioning, identical footprints across power classes, and global certifications for fast deployment anywhere
Thanks to Rittal’s integration with EPLAN, engineers also benefit from a complete digital workflow from planning and configuration to implementation and maintenance, cutting project time by up to 43% according to industry benchmarks.
In one case study, Bosch Rexroth recorded more than 50% energy savings after replacing their older cooling system with a Rittal Blue e+ chiller. When combined with Rittal enclosure cooling units, total energy savings exceeded 80%. Beyond the numbers, the switch also delivered better temperature stability, easier commissioning, and remote system visibility, critical advantages in a global manufacturing operation.
Rittal Blue e+ chillers are trusted across sectors, including:
Machine tools and CNC machining
Laser and welding technology
Food production and packaging
Power distribution and automation
IT infrastructure and data centre cooling
Each model supports a range of configurations, including outdoor siting, stainless steel components, reinforced pumps, and free cooling for even greater efficiency during cooler months.
As sustainability pressures rise and demand for resilient infrastructure continues to grow, cooling systems can no longer be an afterthought. With Blue e+ chillers, Rittal has delivered a platform that blends technical performance with environmental responsibility, digital integration, and long-term reliability.
