E-mobility has changed driving and will continue to do so. Unlike in the past, when the focus was on acceleration, horsepower, and fuel consumption, future priorities will shift to range and autonomous driving capabilities.
In electromobility applications, temperature control systems are essential during both development and production. They are used for battery aging and safety tests, while semiconductors in autonomous driving require precise temperature regulation to ensure optimal performance under varying ambient conditions.
Tailored solutions have been developed to meet these evolving market demands.
Unimotive
Specifically designed for the automotive industry, the Unimotive range operates using a 40/60 water/glycol mixture. This product line can support power outputs of up to 35 kW at a supply temperature of 20 °C and up to 8.5 kW at a supply temperature of -40 °C.
The Unimotive Green Line (GL) range operates in an environmentally friendly manner, utilizing carbon dioxide (CO2) as a refrigerant. CO2 is a natural component of air and, unlike synthetic refrigerants, has a Global Warming Potential (GWP) of only 1. By using this eco-friendly refrigerant, the carbon footprint can be minimized even during the development and testing phases.
The Unimotive GL XT series operates with water/glycol mixtures at temperatures up to 150 °C, utilizing an innovative variable pressure system that sets new industry standards.
Following the "keep it safe and simple" principle, the system is atmospherically open and functions without additional accessories or utilities.
It can also be integrated into higher-level control systems via Ethernet or RS232 interfaces, with supported communication protocols including OPC-UA, EtherCAT Gateway, and Profinet Gateway.
Flow Control Cube (FCC)
In addition to temperature control, flow measurement and regulation are equally important. The FCC enables precise control of the water/glycol mixture flow rate between 0.2 L/minute and 95 L/minute, with an accuracy of ±0.1 L/minute.
Automated Drain & Refill System (ADR)
The ADR enables the application to be drained and refilled automatically, facilitating quick and easy changes of test pieces. Once reconnected, the application is automatically filled, and the temperature control system can be restarted.
Unistat
The Unistat range is compatible with a wide variety of temperature control fluids, making it particularly well-suited for applications in the semiconductor industry due to its broad operational temperature range.
Like the Unimotive series, Unistat systems feature Ethernet and RS232 interfaces, along with communication protocols such as OPC-UA, EtherCAT Gateway, and Profinet Gateway, offering flexible remote communication options. Additional interfaces, including RS485 and AIF, are available as optional accessories.
