Overview
The high and low temperature integrated circulation device is designed with low temperature, high temperature, and circulation integrated, with low temperature up to -80 degrees and high temperature up to 200 degrees, and has the characteristics of high efficiency, convenience, and safety. More precise temperature control, faster cooling, and faster heat exchange. It is mainly used in double-layer reaction vessels, fermentation tanks, rotary evaporators, etc. to provide a second constant temperature environment. The liquid circulation of the entire system of high and low temperature series devices is closed, without generating oil mist or medium evaporation and water absorption. The pre cooling, cooling, and heating systems can be used in combination.
Product Details
Product Name: GDX Series High and Low Temperature Recirculators
Brand: Nanjing David
Product Features:
1. This seriesHigh and Low Temperature Integrated Cycle DeviceAll compressors use * compressors, which have stable performance and reliable quality. The relays, protectors, capacitors, and other components used in the refrigeration unit are all imported high-quality equipment, ensuring reliable performance and service life.
2. Adopting a closed loop system, the heat transfer fluid will not produce oil mist at high temperatures, and is not easily volatile or oxidized; Not affected by the environment at low temperatures.
When the temperature drops from high to low, refrigeration can be directly started, and high and low temperatures can be switched at any time.
4. The heating adopts a pressure resistant stainless steel chamber, which is corrosion-resistant, rust proof, and resistant to low and high temperature liquid pollution.
5.High and Low Temperature Integrated Cycle DeviceThe high temperature control adopts an air switch start button, solid-state relay, and intelligent temperature control instrument to work and start without open flames, ensuring safety and reliability. And there are multiple protection devices for delay, overheating, overcurrent, and overvoltage.
