LN2 shock cooling
Additional cooling for connection to an LN2 supply on the customer’s premises to support cold shocking.
Air to air vertical shock chambers
ShockEvent T is a dual-chamber vertical shock test chamber. The hot chamber (top) and cold chamber (below) are arranged on top of each other. It compresses the “transfer zone” between the cold and hot zones with a transfer time. The test specimen moves between these two chambers in a basket, secured with protection grids. The weisstechnik vertical shock chambers allow the performance of endurance tests of over 1000 cycles without defrosting.
This makes the ShockEvent T unique.
Protect your valuable test material.
Triple test material fuse included as standard. Active test items can be deenergized via a potential-free contact. Test chamber can switch off in the event of a fault in the test material or be set to a defined value (optional).

Test Material and Test Cabinet Protection
Independently adjustable temperature limiter tmin/tmax, separate sensor installed in the test chamber. Dehumidifier to prevent condensation formation on the sample. Software temperature limiter tmin/tmax, individually adjustable fixed value. Potential-free contact specifically for heat-emitting test specimen, connected to socket max. load 24V 0,5A.<br />
Hot chamber
The hot chamber is located above the cold chamber. The test specimen is set into the lifting basket in the hot chamber. It can be used in single-chamber mode.
Test specimen protection hardware
Test specimen protection hardware, as well as software, is also part of the standard equipment. With its own Pt100 probe and hardware, it is system-independent and can effectively protect the test specimen from incorrect temperatures in the event of a fault.
Cold chamber
The cold chamber is underneath the hot chamber and may only be opened for maintenance work. Just like the hot chamber, it can be used in single-chamber mode.
Expansion bag
During the transfer between the cold and hot chambers, the air volume in the test space changes abruptly. The expansion bag accommodates excess air in the case of overpressure and releases it again when there is underpressure. This stabilizes the pressure in the test space and ensures failure-free continuous operation of more than 1000 cycles without defrosting.
Lockable test room door
Door adapted for one-hand operation, lockable, hinged on the left side. <br />
Integrated touch display
Operation/programming and monitoring unit with 18 cm (7"). With this, all settings can be made and test programs can be conveniently programmed.
USB and Ethernet
Standard USB port for data recording, as well as an Ethernet port. Control and data recording via the network connection with our S!MPATI® software. Control via external programs using the SimServ protocol is also possible.
Master switch
The master switch allows the user to turn the entire chamber on and off centrally with just one movement. This helps to save energy and increases safety when the device is not in use.
Ceiling port
The standard equipment includes an access port through which cables can be routed into the lifting basket. A further access port is possible as an option.
Lifting basket
The stainless steel lifting basket (1.4301) moves smoothly between the hot and cold chambers on a spindle. A protective grid and tube protect it against soiling and accidental touching. Limit switches monitor its position. During loading and unloading, an engine brake and a mechanical locking system provide additional safety.
How the vertical shock test chamber works
| The ShockEvent T air-to-air vertical shock test chambers are equipped with two separate temperature chambers, a hot and a cold chamber. A test specimen basket mounted is mounted on a vertical lift between the two zones. This type of construction is called the “elevator type”. Each zone is permanently and independently set to its target temperature. The test specimen moves vertically in a basket from the hot zone to the cold zone or vice versa. As a result, it is exposed to an extreme temperature change within seconds. The test specimen remains in the zone until its core temperature reaches the required stability. This usually takes between 10 and 30 minutes. |
We develop the optimal solution for your application.
The ShockEvent T is ideal for conducting common thermal shock test standards. In single-chamber operation, it works like a classic temperature test chamber and therefore also be used for selected cold tests.

Normal operation – precision and compliance standards.
In normal operation, the ShockEvent T works according to classic test principles and is therefore the preferred choice for standard-compliant and reproducible temperature change tests. The chambers are precisely set to the target temperatures. After transfer to the respective chamber, the test specimen is subjected to a defined holding time. During this time, the temperature is continuously monitored to ensure that the test conditions meet the specifications. This mode is particularly suitable when the test temperatures are close to the maximum or minimum specification values for the test specimen or when high precision and comparability of results are required. Normal operation ensures reliable compliance with standards such as IEC 60068-2-14 and is ideal for quality-critical validations and certifications.
Time-optimized operation – Efficient test cycles for maximum productivity.
Time-optimized operation of the ShockEvent T is specially designed to significantly accelerate test cycles and increase efficiency in the testing laboratory. In this mode, temperatures in the hot and cold chambers are deliberately increased or lowered beyond the target values, so that the test specimen reaches the required temperature more rapidly after transfer. The holding time can be shortened, since the test specimen stays longer in the target temperature range and the temperature is within the tolerance more quickly. This allows for significant time savings per cycle and makes it ideal for applications with high throughput or tight time frames. Time-optimized operation is particularly relevant for serial testing in which speed is paramount but without compromising on testing quality.
Energy-saving operation – sustainable efficiency and maximum cost savings.
The ShockEvent T is equipped with the innovative GreenMode as standard. This intelligent energy-saving mode was specially developed for demanding thermal cycling tests. Thanks to smart controls, optimized components and intelligent software, the GreenMode reduces energy consumption by up to 32% depending on the test time and at the same time ensures cost savings of up to 40%. At the same time, testing quality is fully maintained – a real advantage for energy- and cost-conscious companies.
In addition, users benefit from reduced cooling water consumption, lower grid load, lower noise emissions and sustainable reductions in CO₂.
