Refrigerated Circulators by SJ
SJ refrigerated circulators are trusted by users around the world.
From scientific research and material testing to industrial and technical systems, SJ provides reliable and efficient temperature control solutions across a wide range of applications.
Driven by practical requirements and long-term user experience, SJ has continuously refined its temperature control technology to deliver stable performance, ease of use, and long service life. Our refrigerated circulators are designed to support demanding daily operation in laboratories, pilot plants, and industrial environments.
The SJ range of refrigerated circulators offers a functional and dependable solution for precise temperature control in routine and advanced applications.
Refrigerated / Heating Circulators or named Thermostatic Circulator
Operating temperature range: -40 °C to +200°C ,optional ultra low temp from -90 to 200 °C
SJ refrigerated and heating circulators ensure efficient and stable temperature control for both internal bath applications and external closed-loop systems. High heating and cooling capacities enable fast heat-up and cool-down times, improving workflow efficiency and reducing waiting periods.
Available in multiple sizes and performance classes, SJ circulators can be flexibly adapted to individual temperature control requirements. Whether used for direct temperature control in an open bath or for circulating temperature-controlled fluid to external devices, the systems deliver consistent and reproducible results.
Designed for Practical Daily Operation
Every SJ refrigerated circulator is engineered with user convenience and maintenance efficiency in mind.
Key design features include:
Easy-access ventilation panels for quick removal of dust and improved long-term reliability
Side-mounted drain outlet for clean and safe draining of bath fluids
Ergonomic handles or castors (model dependent) for easy transport and relocation
Robust construction suitable for continuous operation in laboratory and industrial environments
A common application of SJ refrigerated circulators is the temperature control of external closed consumers such as photometers, refractometers, viscometers, reactors, and other analytical or process equipment. At the same time, smaller samples or devices can be temperature-controlled directly within the circulator bath.
How to choose the right bath ?
First consider the use of the desired temperature range. What medium temperature field as the carrier medium used in different temperature ranges is not the same. The medium temperature range according to the general election: ethylene glycol to water (cold), alcohol (ultra low temperature), water (5 to 95℃), dimethly imports silicone oil (high and low temperature applicable) and the like.
According to their actual situation choose how much capacity the bath, the correct and effective working volume is calculated as: working slot opening size plus the groove depth in millimeters.
Is the bath temperature field temperature uniformity requirements. There are two categories:
Basic type: ±0.03℃ and ultra-high-precision:±0.003℃.
Depending on the application, consider if need for external circulation, and what the maximum lift of the outer loop.
