DWR-4 fully automatic low-temperature freeze-thaw test chamber Introduction: This product is for air freezing and water melting. Before powering on the instrument, fill the water storage tank with water, place the specimen in the working chamber, turn on the power, and click to start the equipment. The freeze-thaw machine automatically freezes the specimen in the working chamber to the set temperature in the air. After a period of time (adjustable), the equipment automatically injects water at the set temperature and maintains it at the set temperature for a period of time (adjustable). After the specimen's holding time is over, the water is automatically discharged to the storage tank, and the cycle is increased once to automatically enter the next freeze-thaw cycle. Characteristics: 1. Independently developed and designed the control program for the low-temperature freeze-thaw testing machine, which has been updated and upgraded through years of practical experience. It has automatic control, real-time dynamic display of data curves, automatic storage of test data, automatic recovery of unexpected test termination, water shortage protection, timeout protection, overpressure protection, overtemperature protection and other protection functions to control the smooth and safe operation of the freeze-thaw machine. 2. The structural design is reasonable, making it easy for experimental personnel to operate and reducing labor intensity. 3. The compressor adopts Taikang compressor, and the main refrigeration components are all imported accessories. The Freon uses Kemu 404A high-efficiency refrigerant, which has high refrigeration efficiency and stable performance. 4. Three long axis fans circulate air, and the temperature difference at each point inside the freeze-thaw box during full load operation does not exceed 1 ℃. The fan motor is external and not affected by the humid air inside the box, resulting in a long service life. In addition, the long axis fan is equipped with a fan wheel structure, which provides a larger air volume and better cooling effect. 5. The equipment is equipped with low center of gravity casters, which are easy to install and move, occupy a small area, and have low noise. 6. Device software upgradable: The current software is the latest version. With technological upgrades and customer feedback on the improvement of the device control system, users can upgrade to the latest version and customize different research needs separately in the future. Technical parameters: model: DWR-4 Cooling method of condenser: air cooling Freeze thaw temperature: -35 ℃~50 ℃ Temperature display: The temperature range inside the box does not exceed 1 ℃ Temperature recorder: 7-inch touch screen control instrument Refrigeration compressor: French Taikang compressor Dimensions inside the test chamber: 1000*500*540mm Effective volume: 1000*500*400mm External dimensions: 1700*910*1320mm Test piece capacity: 32 single-layer 100mm × 100 × 100mm concrete test pieces or other specifications of equal mass test pieces Maximum operating power: 4.8kW Equipment weight: 240Kg
