Features of DW-YQ-20/20SJ
- Special relays, protectors, capacitors and refrigeration components for refrigeration units are imported original high-quality devices.
- LED LCD screen temperature display, microcomputer temperature control, simple operation, eye-catching.
- The circulation system adopts anticorrosive materials, with rust, corrosion, low temperature liquid pollution prevention function.
- Not only energy saving, but also the lack of water, water quality, water pressure is not good occasions, can prevent circulating water scaling, pollution prevention. It can effectively protect the normal operation of large precision instruments and equipment under bad working conditions in high temperature areas.
- All models of this machine can be rationally matched between low temperature and cooling capacity, low temperature and container capacity according to user requirements.
