HDK-3 HDK-5 HDK-9 High Quality Rapid Freeze Thaw Chamber

High Quality Rapid Freeze Thaw Chamber

This product meets the freeze-thaw resistance test of concrete specimens with a requirement of 100 * 100 * 400.

The freeze-thaw test chamber’s characteristics1. The compressor uses an imported, genuine US Youle 10PH compressor. It uses the environmentally friendly, high-efficiency, fluorine-free 404A refrigerant.2. Stainless steel large-area filters and stainless steel pipes and liners are used throughout.3. High density insulation layer, effective insulation, energy savings, and environmental protection. Microcomputer control, temperature digital display, adjustable temperature inside the box, automatic door lifting device, reduce labor, convenience, and reliability. 4. Fast cooling speed and reasonable evaporative condenser system design. Ensure that standards are being followed.The primary technical criteria:range of temperatures: -20 °C to 25 °C (adjustable); Temperature uniformity: 2 °C between each point, measurement precision: 0.5 °C, and display resolution: 0.06 °C;Test conditions: The center temperature of the specimen at the end of freezing was -17 2 °C, and the center temperature of the specimen at the end of thawing was 8 2 °C. The freeze-thaw cycle period was 2.5 4 hours, and the thawing time was not less than 1/4 of the freeze-thaw cycle.The sample is heated for 1.0–1.5 hours, followed by 1.5–2.5 hours of cooling.
