High and Low Temperature Liquid-Cooled Testing Machine （-40℃）
Technical Parameters
Zhongzhi's high and low temperature liquid-cooled testing machine (-40℃) comes in six models, each corresponding to a different cooling capacity. All six models have a temperature range of -40℃ to 95℃, which can be extended to 120℃ after pressurization. Temperature control accuracy is ±0.5℃ for all models. The main differences lie in parameters such as heating capacity, flow rate range, and pressure range.

Note:
1. Nominal cooling capacity: Rated cooling capacity of the equipment when the refrigerant temperature is 25℃ and the ambient temperature is 32℃ for air-cooled models or the cooling water temperature is 32℃ for water-cooled models. Refer to antifreeze parameters with a freezing point of -45℃ for refrigerant parameters.
2. Under stable load, ambient temperature, and power supply conditions, the temperature control accuracy can reach up to ±0.1℃.
3. Water-cooled models should have "-W" added to their model designation; water cooling is recommended for models with a cooling capacity of 15kW or higher.
4. Supports 2-channel and 3-channel output channels.
5. Please note if the temperature exceeds 95℃; the equipment requires pressurization. The recommended maximum temperature is no more than 120℃.
6. The minimum temperature can reach -45℃; it is recommended to use a refrigerant with a freezing point below -45℃.

Why Is a Wide Temperature Range Crucial for Liquid-Cooled Testing?
In traditional testing solutions, different temperature conditions may require simulation using multiple temperature control devices. This not only increases testing complexity but can also lead to test interruptions due to device switching, affecting data consistency.
Our high and low temperature liquid-cooled testing machine can achieve temperature control from -40℃ to 95℃, simulating different temperature conditions within a single device, providing a stable liquid-cooled testing environment for automotive components. Here are some advantages of a wide temperature range:
1. One device can simulate multiple temperature conditions
From -40℃ low-temperature cold start testing to 95℃ high-temperature fatigue testing, all tests can be completed within the same device without changing equipment or adjusting the test platform.
2. Improved testing efficiency
High and low temperature tests that previously required phased completion can now be completed continuously on the same device, reducing waiting time and improving testing efficiency.
3. Reduced equipment management complexity
A single control system, a single communication interface, and a single maintenance system reduce the complexity of equipment management.
