Blue e+ units guarantee a longer service life for installed components, global usability and Industry 4.0 capabilities as it harnesses all the benefits of innovative technology.

Become Sustainable

Sustainability is crucial – Blue e+ S cooling  unit’s new refrigerant reduces the Global Warming Potential rating by 56%, ultimately helping to protect the environment while saving you money.


Their hybrid technology and speed-controlled components guarantees targeted, optimum cooling, resulting in energy savings and service life extension.

Become Faster

As time is a critical variable for every company – Blue e+ S cooling units can save time with greater flexibility at every level of engineering, planning, ordering and handling.


Greater flexibility at every level:

  • All data is available in the Eplan Data Porta
  • RiPanel allows your team to configuring the enclosure and cooling
  • Serial numbers are now printed on the packaging
  • The Therm software package allows for more flexible computation of required climate control.
  • Country-specific approvals and unique multi-voltage capabilities

Design Fail-safe Processes

At every stage in the value chain, reliability is key. Blue e+ S cooling units offer maximum reliability, reduced maintenance and rapid usability.


Your go to for reliability:

  • With cooling units of 300 W or higher, integrated condensate evaporation is standard.
  • Avoid machine downtime by immediately identifying device condition via LED optical fibres, even from a distance.
  • A foamed-in seal ensures the IP 55 protection category.
  • Worldwide availability and short delivery times for products and spares
  • Safe to use within the temperature range from -20 to +60 °C

Reduce Your Workload

Planning, operation and assembly are easier with Blue e+ S cooling units allowing you to focus on what's truly important.
