The Cyro series low-temperature cooling circulation pump is a device that uses compressor refrigeration technology, designed specifically for laboratories in the fields of chemistry, biology, physics, etc. It can meet the cooling and temperature control needs of various experimental instruments. This device provides an economical and environmentally friendly cooling constant temperature circulation solution for laboratories. Its compact structural design endows the device with a small external size, making it extremely quiet during operation. Small devices can be directly placed on a desktop or in a fume hood, and even large devices have limited floor space. This device is particularly suitable for experimental equipment such as cooling blocks, steam filters, vacuum pump condensers, rotary evaporators, and heat exchangers, with cost-effectiveness and rapid return on investment.
