Manufacturer of fully automatic low-temperature freeze-thaw testing machine

CLD typeManufacturer of fully automatic low-temperature freeze-thaw testing machine*It consists of three main parts: refrigeration system, control system, and water injection system.

The fully automatic low-temperature freeze-thaw testing machine adopts a three-dimensional structure, all of which are made of high-quality steel. The inner tank and storage tank are made of high-quality stainless steel plates, and the overall structure is sturdy. The materials have been treated with rust prevention and have good corrosion resistance. The main unit adopts an imported fully enclosed refrigeration unit, which has the advantages of small land area, convenient use, and low power consumption. The condenser is made of copper tube with good heat transfer performance. The start, delay holding, and stop of the equipment are all automatically controlled by the instrument for safe and reliable use. This device has high automation, high efficiency, and does not require any adjustment or monitoring. It automatically completes 0-999 freeze-thaw cycles

Working conditions of CLD type fully automatic low-temperature freeze-thaw testing machine:

1. The ambient temperature ranges from 5 ℃ to 35 ℃.

2. The relative humidity of the environment should not exceed 85%.

3. There is no vibration, corrosive medium, or strong electromagnetic field interference around.

4. Place on a sturdy and flat surface.

5. Power program: AC220V ± 5% 50Hz Total power: 2000W.

Technical parameters of CLD fully automatic low-temperature freeze-thaw testing machine:

1. Container liner size: 1120mm in length, 500mm in width, and 520mm in height

2. Cooling rate: approaching or not exceeding 20 ℃/h.

3. Temperature measurement accuracy: -20+20 ℃± 0.5 ℃.

4. Equipment dimensions: 1860mm × 900mm × 1250mm.

5. Weight: Approximately 300kg.

Precautions for CLD type fully automatic low-temperature freeze-thaw testing machine:

1. The power cord of this machine must be connected to the circuit, and the grounding protection wire must be reliably grounded.

2. This system is strictly prohibited from operating under water shortage, and the water pump is strictly prohibited from starting under water shortage conditions.

During the experiment, the equipment should be checked once a day for any abnormal conditions and recorded. The main contents include: whether the instrument display is normal; Is the water temperature and level normal; Whether the compressor and water pump are working properly; Is the air cooler and compressor condenser fan operating normally inside the insulation box.

3. There are no user adjusted or repaired components inside this machine. If there are any problems, please have professional personnel inspect and repair them. It takes approximately seven days to conduct 100 cycle tests on ceramic tiles at the rated sample weight and an ambient temperature of 20 ℃. The actual test time varies greatly, mainly depending on the ambient temperature and sample weight.

The weight of each test sample should be as close as possible to 60Kg, which will cause frequent compressor start-up.
