Overview
DHJF-1050 low temperature (thermostatic) stirred reaction bath is a patented product independently developed by GREATWALL. It adopts single-stage compression and partial condensation refrigeration full series combined heat exchanger technology, which realizes ultra-low temperature below -100 ° C for a single Compressor. Compared with the traditional three-stage cascade refrigeration system, the structure is simpler and Reliability is higher.
Features
1. Own core technologies (national patented products).
Adopting single-stage compression and split condensation ultra-low temperature technology can meet the needs of -100 ° C to -120 ° C.
3. Refrigeration Compressor and other key components adopt American, German and French brands, with high Reliability.
4. Key input and digital display, easy to operate, easy to monitor operating status parameters.
5. The material of the circulation system is 304 stainless steel and polymer anti-corrosion material, which can prevent rust, corrosion and low temperature liquid pollution.
6. There is no circulatory system below -100 ° C.
Principle
The product adopts the full series combined heat exchanger technology of single-stage compression and partial condensation refrigeration. Its core is the series heat exchanger of the outer coil of the coil evaporator, which is composed of a multi-stage condensing inner tube of the evaporation outer tube and its inner cavity. Through a Compressor to form a multi-stage refrigeration system, ultra-low temperature refrigeration is realized.
Applications
Low temperature chemical reactions, low temperature testing of materials, low temperature processing of biological samples, laboratory or industrial reaction processes requiring ultra-low temperature thermostatic stirring
Standards
