Overview

DHJF-1230 low temperature (thermostatic) stirred reaction bath is an ultra-low temperature equipment independently developed by GREATWALL. It adopts the core technology of single-stage compression and partial condensation refrigeration full series combined heat exchanger, and the cooling temperature can reach -120 ° C. The product simplifies the complexity of the traditional multi-stage cascade refrigeration system by optimizing the system structure and improves the operation Reliability.

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, Reliability and effectiveness. 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 self-developed single-stage compression and fractional condensation refrigeration full-series combined heat exchanger technology. This technology uses a Compressor and a series heat exchanger with a coil evaporator jacket and coil to form a multi-stage refrigeration system. The series heat exchanger is composed of a multi-stage condensation inner tube with an evaporation outer tube and its inner cavity. The structure is simpler than that of the traditional cascade refrigeration system, reducing the welding point and improving the operation Reliability.
