Overview

The laboratory low-temperature refrigeration machine has multiple protections such as self diagnostic function, compressor overload protection, exhaust pressure protection, circulation pump overload protection, low liquid level protection, and phase loss and wrong phase protection.

Product Details

Laboratory low-temperature refrigeration machineFeatures:

◆ Wide working temperature range, temperature range from room temperature to -105 ℃.
◆ Equipped with a 7-inch touch screen display controller, it intelligently controls temperature. Siemens PLC has stable performance.
The touch screen records temperature curves, historical data, fault alarms, and supports data export via USB flash drive.
◆ Use environmentally friendly refrigerants.
Imported compressors such as Gulun, Taikang, Danvers, etc. have stable performance and reliable quality.
◆ Adopting multi-level stacking technology.
◆ Has self diagnostic function; Multiple safety features such as exhaust high pressure alarm, thermal protection, low liquid level protection, phase loss and phase mismatch protection, etc.
Control the temperature of the thermal conductive medium, and use the same thermal conductive medium throughout the entire temperature rise and fall process.
High head design, suitable for long-distance transportation of thermal conductive media.
