High-precision temperature control solutions for the automotive industry
Particularly high requirements apply in the automotive industry. Researchers and engineers all over the world trust our temperature control technology because of the following features:
There are numerous applications for our temperature control units in the automotive industry. Typical areas of application are, for example, environmental simulations, material testing as well as temperature-dependent stress and load tests for materials, transmissions, bearings and engine parts.
Another frequent field of application is research tasks, test series and quality control on batteries, accumulators and electronic components. Researchers and engineers around the world rely on our temperature control technology for the design, construction and operation of test benches in the automotive industry.
Fuel temperature control
Our temperature control units are used for cyclic heating / cooling of gasoline or diesel. The service life of the fuel tank surface is tested by cyclically heating and cooling the fuels. Dynamic temperature control systems that perform rapid temperature changes and cover a wide temperature range are particularly suitable for the test.
Filterability limit
The most important test for the cold resistance of diesel fuel is the filterability according to the CFPP, the Cold Filter Plugging Point Test according to EN 116. At temperatures below freezing, kerosene crystals can increase the flow resistance in the fuel filter so that sufficient fuel delivery is no longer possible.
Material deformation
Components such as condensers, air ducts and outlets are exposed to frequent temperature fluctuations between -90 °C and +150 °C. The material behavior of the various components can be tested with cold bath circulators under different load conditions.
AdBlue® tempering
The application takes place in the SCR catalytic converter (selective catalytic reduction, SCR). There, selective catalytic reduction reduces emissions of nitrogen oxides (NOx) by around 90% (in stationary operation). The fluid is a water-clear, synthetically produced 32.5 percent solution of high-purity urea in demineralized water.
Outgassing test
For fogging testing (according to EN 14288 and DIN 75201) of individual components of the car interior in the laboratory, we offer various temperature control units. During heating, the volatile components escape from the component and precipitate in the (colder) component environment. The KISS and CC series are used to heat the bath, while a Minichiller 280, for example, ensures proper cooling.
Gear oil test
For gear oil tests, for example, a Unistat with working temperatures from -40 °C to +250°C can be used for temperature control. The gear oil is pumped through a plate heat exchanger and passes through defined temperature profiles in different cycles.
Softening temperature
The Vicat test is used to make statements about the softening temperature of plastics. With a defined compressive stress and a constant increase in ambient temperature, a round needle with a flat end is pressed onto the surface of the specimen. Depending on the test condition selected, a constant temperature increase of 50 °C or 120 °C per hour must take place until the softening point (VST) is reached and the needle has penetrated 1 mm deep into the material.
Optics
Huber temperature control systems are used for high-precision temperature control of calibration and vacuum chambers to test and calibrate the optical equipment. Under high vacuum, the parts and functional components are exposed to real conditions.
Additives, lubricants
Temperature-dependent test methods for the development, optimization and quality assurance of additives and lubricants. Typical objectives are the improvement of low-temperature behavior or viscosity as well as the optimization of aging resistance, corrosion protection, dispersibility and foaming behavior.
Pump test
Temperature control of pump test benches for pumps for liquid and gaseous media. Precise temperature control ensures high measurement accuracy and reproducibility for all parameters. Typical tests where the temperature influence plays a role are pressure tests, flow rate measurements, noise measurements, power consumption, leak tests and long-term durability tests.
Sensors
For functional testing and calibration of sensors, e.g. Pt100 sensors, Unistats are suitable in combination with the Unical calibration bath. The stainless steel bath is constructed in the manner of a calorimeter and thus achieves very good temperature homogeneity. Individual temperature cycles can be set by means of a programmer or by control via a digital interface.
Corrosion test
Body components are exposed to temperature fluctuations, wetness and environmental influences on a daily basis. In special test chambers, these environmental conditions are simulated with fog, dry phases, salt solutions and other corrosion solutions. Cyclical temperature fluctuations are important here. Dynamic temperature control units from Huber are suitable for this purpose in order to test precise temperature changes over several test phases.
Material stress test
In the automotive sector, all vehicle components must be subjected to a wide variety of stress tests - often under extreme climatic conditions. The components have to withstand these stresses with cyclically changing temperatures for several weeks or months. Unistats are the first choice for this. The devices are designed for reliable continuous operation and allow extremely fast temperature changes.
