E
-mobility has changed driving and will continue to do so. Whereas in the past the focus was on acceleration,
horsepower or fuel consumption, in the future it will be on the range or the level of autonomous driving. For applications in the field of electromobility, temperature and control systems are required during the development phase as well as in production. With batteries, temperature
control systems are used, for instance, for aging and safety tests. Semiconductors used for autonomous driving are likewise temperature-controlled to ensure that they function under different ambient conditions. Appropriate solutions have been developed for exactly these market requirements.
THE UNIMOTIVE RANGE Specifically developed for the automotive industry, Peter Huber Kältemaschinenbau’s Unimotive range can be used with a 40/60 water/glysantine mixture. The product range can cover a power range of up to 35kW at a supply temperature of 20°C and up to 8.5kW at a supply temperature of -40°C. The Unimotive GL
(Green Line) range operates in a climate- friendly manner using carbon dioxide (CO2) as a refrigerant. CO2 is a natural component of air and, unlike synthetic refrigerants, has a GWP of only

one. Using this climate-friendly refrigerant, the carbon footprint can be kept as low as possible even in the development and testing phase. The Unimotive GL XT series can be
operated with water/glysantine up to 150°C. To enable the plant to reach the 150°C, the Unimotive GL XT operates with an innovative, variable pressure system, which sets new standards. In line with the motto ‘keep it safe and
Exploring state-of-the-art temperature and flow control for e-mobility
simple’, the plant is atmospherically open and can be operated without additional accessories or utilities. The systems can be integrated into a higher-level control system by means of an ethernet or RS232 interface. The available protocols include OPC-US, EtherCAT-Gateway and Profinet-Gateway.
FLOW CONTROL CUBE Besides temperature, flow measurement and control play an important role as well. With Huber’s Flow Control Cube (FCC), the flow rate of the water/glycol to the application can be controlled between 0.2l/min to 95l/min with an accuracy of up to +/-0.1l/min.
AUTOMATED DRAIN AND REFILL Additionally, Huber’s Automated Drain & Refill System (ADR) allows
The wide operational temperature range makes the Unistat product line ideally suited for applications in the semiconductor industry
