Common Misunderstandings In The Selection Of Ultra-Low Temperature Compressor, Pure Dry Goods 来了
In the market of extreme low-temperature refrigeration equipment, many purchasers have formed wrong cognition when selecting -150℃ ultra-deep cold compressors. These misunderstandings will lead to wrong selection, mismatched equipment and waste of project funds. This pure dry goods sorts out the most common misunderstandings in the industry and gives objective analysis.
The first misunderstanding: the lower the marked temperature, the better the equipment. Some suppliers mark ultra-low temperature parameters on the product brochure, but the equipment can only reach this temperature under no-load conditions, and cannot maintain stable refrigeration under actual load for 24 hours. XTLD customized ultra-deep cold compressor’s -150℃ index is verified under simulated actual working load, not just no-load test data. Users should confirm whether the temperature index is under load condition.
The second misunderstanding: ultra-low temperature compressors of different brands can replace each other. In fact, each customized unit is designed for specific working condition parameters. Different compression ratio, refrigerant formula and material configuration determine that they cannot be replaced casually. Blind replacement may cause system failure and sample loss in scientific research experiments.
The third misunderstanding: ignore after-sales and only focus on hardware price. Ultra-deep cold compressor belongs to high-precision customized equipment; later calibration, maintenance and fault solving all rely on professional technical support. Some cheap suppliers lack the ability of extreme low-temperature equipment maintenance. When comparing and selecting manufacturers, take comprehensive service capacity into consideration, instead of judging quality merely by quotation.
