The ClimeEvent, Now with Eco-Friendly R744 (CO2) Refrigerant

From 1 January 2025, refrigerants with a Global Warming Potential (GWP) of 2,500 or more will be banned for servicing refrigeration equipment, with the complete phase-out of HFCs set for 2050. To stay ahead of these regulations while enhancing performance, Weiss Technik has upgraded the ClimeEvent climate test chamber with R744 (CO₂) - a natural refrigerant with a GWP of just 1 and zero ozone depletion potential.

 

Known for its high heat transfer efficiency, stability and compatibility with compressor lubricants, R744 is an ideal replacement for traditional refrigerants like R134a and R404a. Alongside this environmentally friendly upgrade, ClimeEvent continues to deliver precise and reliable temperature and humidity testing, with enhanced humidification and dehumidification performance and a new control system for even greater accuracy, ensuring your products meet the highest standards of durability and functionality.

This makes the ClimeEvent unique.

New Climate-Friendly Refrigerant R744.

Our single-stage systems (down to -40C) will be replaced by CO2 systems with Global Warming Potential (GWP) of 1 on 1 January 2025. Even at -40C, the system still offers sufficient power to operate your test material.

Connectivity is key.

Versatile thanks to our in-house Simpati software.
Flexibility thanks to various interfaces (SimServ interface, LabView, OPC-UA, ProfiBus, ProfiNET or EtherCT).
ASCII can still be used.

Even more precise humidity values and simple management of the humidification water.

Humidity control ensures control accuracy for climate change tests and extreme temperature and humidity conditions.
Large water bath for increased humidification and dehumidification performance.
25L water tank – automatic make-up included as standard.

Protect your valuable test material.

Triple test material fuse included as standard.
Active test items can be de-energised 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).

Shield your test material from prying eyes.

With our patented ‘smart’ test item protection, you can protect the test environment from prying eyes.

Customised to the requirements of your test.

Every test item and test is different. Our temperature and climate chambers can be customised to the requirements of the test material and the test.

LED Test Room Lighting

In the test chamber, there is an LED ceiling lighting. It ensures uniform and bright illumination, even when standing in front of the test chamber and blocking the incoming light with the upper body.

LED status bar for a quick overview

The LED bar shows the test progress in green. Warnings (orange) and alarms (red) are also displayed. A glance into the laboratory in the morning is enough to see the status of all systems.

Window in the door with optional privacy screen

Often, a good view of the test specimen is important. Therefore, our chamber can be equipped with a heated and 5-fold glazed pane. Together with the bright LED lighting in the test room, they ensure clear visibility under all test conditions. Sometimes, however, it is also important to protect the test object from prying eyes. In this case, the pane becomes opaque at the push of a button (optional).

Foldable web panel 25.4 cm (10“)

The 25.4 cm (10“) display is foldable. All settings can be made via the touch panel, and test programs can be conveniently programmed.

Water tank for climate tests

For climate tests, there is a water tank below the test room door with a capacity of 27 litres. If a corresponding water supply is available (included in the basic equipment), it can be filled manually or automatically. Optionally, a demineralization unit can be installed.

Digital inputs and outputs

With this, the test object can be controlled via appropriate circuits. For example, it can be switched on and off via the digital channel using a relay. Optionally, a specific behaviour of the test chamber can be programmed via the inputs. For example, in the event of solidification of the test object, the test chamber can be regulated to room temperature to prevent aging of the test object.

Efficient humidification system

Deep inside is our humidification system for climate tests. It is designed to be very robust against outgassing of the test object and does not require additional infrastructure such as compressed air. With the water bath, a large climate range can be covered. Only at very high humidification performances or low dew points are steam humidifiers or compressed air dryers required.

USB and Ethernet

In the basic equipment, a USB port for data recording (csv) and an Ethernet port are available. The cabinet can be controlled via the network connection with our software S!MPATI® or the data can be recorded. Additionally, the cabinet can also be controlled by external programs via our own protocol SimServ.

We develop the optimum solution for your application.

Automotive: Demanding climate tests such as those from LV124 or general standards such as the IEC 60068 series pose no challenges for our test chambers. Not even in the field of e-mobility.

Electronics: Our test chambers are designed for a wide range of tests in the electronics industry and easily master these specific requirements; e.g. low-silicone test chamber.

5G and autonomous driving: There are often very specific requirements in this area. Special adaptations enable testing in the EMC area or of lidar sensors. 

Aeropace and defence: In this area, extreme demands are often placed on the product. Our chambers can be used to test corresponding standards from the aerospace or defence sector.

Consumer products: Consumer and luxury goods must also be tested. These sometimes pose special challenges for the test chambers, such as tests with leather, which introduces highly corrosive outgassing into the test chamber. Here too, we have already provided solutions for our customers on several occasions.

Special applications.

Lithium ions: Rechargeable batteries are installed in many devices these days, and e-mobility is also leading to an increased number of tests with batteries. To ensure that you can test these test items safely, our test chambers are equipped with a tested safety system based on the EUCAR Hazard Level System, which extends up to Hazard Level 7.

ATEX: Many test items use flammable substances as lubricants or operating fluids. A risk assessment is required in order to be able to test safely even in the event of a leak in the test material. If necessary, measures must be taken at the test chamber. We offer you advisory support and equip your test chamber with a tested safety concept.

ESD: Some test items are very sensitive to electrostatic charge. The test chambers can be equipped accordingly to prevent this from happening in the test chamber, for example through air movement. From the earthing point to the shielding of all installed components. 

EMC: The test chambers must be specially shielded to ensure that no signals are emitted from the test object into the environment or affect your test object. We have many years of experience in the construction of test chambers for EMC tests.

Corrosive gases: PCBs and plug connections in particular must be tested under conditions with corrosive gases. Appropriate equipment is also available for this purpose.
