A great amount of information is generated when it comes to operating climate control solutions in enclosures. With the cooling units and chillers in the Rittal Blue e+ range, values and other information can be measured and recorded. This includes the temperatures inside and outside the enclosure, the evaporator and condenser temperatures and, where appropriate, measurements from additional sensors located inside the enclosure. Instead of a simple operating hours meter, the run-times of the compressor and internal and external fan are recorded separately. There are also system messages, data for capacity utilization, and the current parameterization information.

In order to generate added value from the high volume of data, the information must be made available to superordinate systems. To make the seamless communication of data possible, the company offers its IoT gateway, which turns the cooling units and chillers into IoT-compatible devices. The product can either be mounted on a top hat rail or directly on the cooling unit or chiller. The protocols supported include CANopen. This makes it is possible to connect to superordinate monitoring or energy management systems in virtually every case. The data from the CANopen devices is then available in these systems at all times. It is also possible to set parameters and configure settings via the gateway.

The information from the devices, in particular sensor such as for temperature, humidity, etc. can also be used for a range of analyses. The communication options available through the gateway make it possible to integrate the climate control solutions into IoT applications. For example, the options make optimization of maintenance and servicing of climate control solutions possible, lowering operating costs, said the company. Another application is energy data management. With all data available at all times, the level of energy efficiency is increased, which in turn helps reduce costs, the company added.
