Manufacturer of concrete rapid freeze-thaw testing machineAdopting the water freezing and thawing method, the frost resistance and thawing test of concrete specimens with a size of 100 * 100 * 400 that meet the appearance requirements can be conducted. Nine sets of specimens (28 including one central specimen) can be placed at a time. During the experiment, the test piece is placed in a test rubber cylinder, which is filled with water. The rubber cylinder is then placed in a test piece box containing antifreeze, and the unit's cooling or heating of the antifreeze is used to freeze or melt the test piece in the rubber cylinder, thus completing the freeze-thaw test.

The entire operation is fully automatic and does not require human intervention. When the test is completed to the set (default of 50 times), it will automatically stop and emit a prompt sound to indicate the completion of the test. If the test needs to continue, it can accumulate the set number of times and then continue running.

Functional features:
1. Energy saving and low-noise, using intelligent thermal storage technology to fully utilize the heat generated by the compressor during refrigeration, which is consumed during the freeze-thaw cycle in overtime. Reduce the power consumption of the entire machine to one-third of that of regular freeze-thaw cycles. Not only does it save energy, but it also reduces operating noise, and enables the refrigeration unit to operate at low loads, ensuring the service life and stability of the equipment. It has the characteristics of stable operating curve, energy saving, and low noise.
2. The KDR-V series freeze-thaw microcomputer measurement and control instrument is a measurement and control instrument independently developed by the company. We have independent intellectual property rights and are tailor-made for freeze-thaw. It comes with a large capacity data storage and can continuously store up to 30 days of operating data. It can be connected to a micro printer for automatic printing, or connected to a computer for software control and data export analysis.
3. A complete protection system, including power phase loss protection, power undervoltage protection, power short circuit overload protection, unit refrigerant overvoltage protection, unit refrigerant undervoltage protection, etc. All protections can be alarmed in real time through instruments and display fault conditions. After the fault is resolved, press any key to release the alarm.
4. Freeze thaw measurement and control professional version software, independently developed and designed, using NET2.0 framework design, with fast running speed and system resource occupation.

Application fields:
Suitable for concrete frost resistance tests using dynamic modulus of elasticity, weight loss, and relative durability index as evaluation indicators. The durability testing of various concrete engineering projects such as marine engineering, hydraulic engineering, bridges, tunnels, industrial and civil buildings is one of the * equipment in the concrete durability testing laboratory of scientific research institutions.
