Versatile applications of modern chiller solutions

The Blue e+ chillers offer a wide range of applications and demonstrate their strengths where precise cooling is essential: in industrial manufacturing, under harsh outdoor conditions, and in energy-efficient climate control of small data centers.

Digital benefits for a smaller carbon footprint

Add value by thinking holistically – Blue e+ S chillers help your processes run even more smoothly with smart apps & services.

Connect your smartphone to the chiller via NFC to transmit the unit's data, or scan the QR code to see all relevant product information at a glance:

Faster configuration and commissioning of your chillers
Create and send service messages
Generate and send wish lists of accessories and spares

The IoT interface is a central component for smart networking of Rittal cooling solutions or sensors used to monitor ambient conditions. Equipped with a wide range of interfaces and protocols, it collates and transmits data to high-level IT systems or systems for local monitoring of machine conditions and health.

More efficient, by ensuring optimised integration of cooling units, Blue e+ chillers and sensors into Industry 4.0 applications
Faster, thanks to seamless communication from the sensor to the cloud
More reliable, by linking to high-level monitoring or energy management systems

Chiller options

More flexibility with preconfigured chiller options: Our chiller series opens up a wide range of application possibilities. No matter where you want to use your chiller, we have the right option for you. Thanks to preconfigured options, delivery times are shortened and the ordering process is simplified.

Increased-output pump:

If a higher pump cooling medium flow rate or pressure is required, the pump can be designed to include a higher performance option.

Inverter pump:

The cooling medium pump can be designed as a speed-controlled pump, whose speed is regulated depending on the actual cooling medium requirements and adapted to the existing hydraulic system.

Oil/emulsion:

Low-viscosity oil (up to ISO VG 48) or emulsion may also be used as a cooling medium instead of the water-glycol mixture used as standard (pump and hydraulic tank must be provided by the customer).

Laser application:

With pipework free from non-ferrous metals, deionised water may be used as the cooling medium.

Heater:

A tank heater may be installed to pre-heat the cooling medium or for frost protection.

Industrial connector:

The mains and communications cables can be fitted with robust industrial connectors.

Water-cooled condenser:

A water-cooled condenser emits waste heat to the existing cooling water network, thus preventing the surroundings from heating up.

Colour:

Standard RAL colour shades are available as a special spray finish.

We are here for you.

We'll be delighted to answer all your questions relating to sustainable Blue e+ cooling technology.
