Thermal Vacuum Chambers (TVC)

Space Simulator
Testing space flight equipment before the first flight into space is a prerequisite to be able to predict the behaviour of these valuable components and is done by simulating space conditions. Weiss Technik’s Thermal Vacuum Chambers accurately reproduce outer space conditions and thus allow testing in a completely controlled environment. Our high performance pump systems can achieve a vacuum of down to 10ˉ⁷ mbar.

 

  • Independent thermal zones
  • Secondary vacuum pumping system: turbomolecular or cryogenic pump
  • Cooling system: mechanical, liquid or gaseous nitrogen
  • Powerful supervision software (Spiral VS)

 

Specific features such as infra-red radiation or aspatial temperature gradient can be simulated to meet our customer requirements.

Equipment

Weiss Technik Climate Control Technology

Conditions such as cleanliness, temperature, humidity, pressure and their permitted fluctuation tolerances are vital for development, production and testing processes. With a wide product portfolio, Weiss Technik Climate Control technology offers systems for every application, from complete clean rooms, measurement spaces, process climate systems and individual work benches to special climate control systems for data centres.

At Weiss Technik, customised solutions are our strength.

Controlled process environment

Clean rooms


With product range ultraclean®, we offer integrated systems for all clean-room classes and application areas. Our sphere of competence reaches from simple housing of machines over laminar flow-systems up to complex clean-room facilities. Our system solutions ensure compliance with national and international clean-room standards, e.g. VDI 2081 or DIN EN ISO 14644.

Clean Rooms

Measuring rooms


Weiss Climate Control Technology plans and realises customised measurement units pursuant to the requirements of VDI/VDE 2627. These reduce the rate of measurement error by suppressing temperature impact, for instance by preventing drafts or direct light, by encasing the measurement device and by installing thermal insulation in the measurement unit.

Test to the limit

Altitude Chamber – temperature, climate, vacuum

Weiss Technik test chambers facilitate the testing of aerospace components in an environment that allows control of the parameters pressure, temperature and/or humidity. It is possible to simulate heights of 100,000 feet. Upon request, combined icing tests cat B can also be performed according to the norms RTCA DO-160 and MIL-STD-810.

Testing Systems for highly accelerated aging and stress tests

The HALT stress test (Highly Accelerated Life Test) examines step-wise and spasmotic thermical stress, also in combination with vibration. Thereby the usage limits of a product during the prototype phase are determined and weaknesses in design and components are revealed.

Kerosene Climatic Test Bench

Weiss Technik provides solutions to test your critical pieces of equipment with preheated or cooled kerosene, and the possibility to simulate water pollution and icing conditions. Combined with a climate/altitude chamber, it is then possible to simulate real operating conditions.

Low Temperature Chamber (LTC)

Low Temperature Chambers from Weiss Technik achieve rapid temperature changes and great homogeneity, in small volumes as well as in large walk-in chambers. Our liquid nitrogen cooling system allows a very precise temperature adjustment over a large range, from –185 °C to +200 °C.

Temperature-Shock Testing Cabinet

During flight, aircraft equipment often passes through several temperature zones in a brief period of time. Rapid temperature changes can impact the function and safety of individual components. weisstechnik Testing Cabinets allow for temperature changes of up to 30 K/min.

Vibration Testing Cabinet

Airplane engines, rotor blades and space craft experience intense vibrations during take-off and landing. At the same time, these components experience rapid temperature changes in different types of climate. The weisstechnik series WT3-V and WK3-V permit the simulation of such dynamic processes in order to plumb the stress limits and thus allow for safe flight operation.

Stress Screening System

During the ESS test, the products are subjected to precisely-prescribed stress in order to recognise defects in components and circuit boards timely in the production plant. Unreliable systems are scrapped before reaching the customer. High product reliability is very often the only difference between different manufacturers.

Tension Test Chamber

Tension tests must be performed under prescribed climate conditions in order to ensure the quality of materials during use. With our tensile test climate chambers, you can determine behaviour under real environmental conditions and thus ensure the usability of new materials under harsh airspace conditions.

Corrosive Gas Testing Cabinet

The effects of corrosive gases can corrode materials. In order to detect possible susceptibility, we expose aerospace components to precisely dosed gas volumes in a climatised air environment. Relevant for testing are H₂S, SO₂, CI₂ with carrier gas and N₂, NO₂ with carrier gas synthetic air and other gases upon request.

Lithium-Ion Testing Cabinet

Energy storage units are important components in aerospace, which also must stand up to extreme conditions. Comprehensive safety equipment: CO₂ cooling and neutralisation, H₂ concentration measurement, CO and CO₂ concentration measurement, safety temperature limiter, electro-mechanical door clamps.

Sun Simulation Chamber

Surfaces and materials can react to long-term sun light irradiation. Our test chambers for global and UV radiation let you test your products for any quality deficiencies with reference to sun radiation. In addition, it is possible to pretreat products with UV radiation before testing in a temperature or climate chamber.

ESA places its trust in our climate and cooling technology

For about 30 years we have been developing, building, maintaining, repairing and caring for the climate control and cooling systems of the ESA ground stations worldwide. The Deep Space Antenna DSA3 of the European Space Agency (ESA) reaches an imposing 40 metres into the air. This system, at the foot of the Andes in the Argentinian Malargüe, plays an especially important role. It completes the network of ESA ground stations in place for researching space and its missions. In order to protect the sensitive electronics of the ground station from dangerous climate fluctuations, ESA places its trust in climate and cooling technology with 100% redundancy by Weiss Technik.

“When we buy products from Weiss Technik, we simply know that they work reliably,” explains Filippo Concaro, manager of the European Space Operation Center (ESOC) of ESA. “The quality simply speaks for itself and has done so for decades.”
