Product Overview
This new generation of compact recirculating chillers has a new CFC-free, environmentally friendly design to keep you at the forefront of healthy living. Incorporating adopted overseas technology, it offers precise temperature control, compact volume, branded compressors and circulating pumps, low noise, high flow, rapid cooling, high efficiency and low energy consumption. It promotes energy savings and provides long service life, with cooling time reduced by 35% compared with conventional equipment.
Product Features
- An LCD controller displays multiple data sets on one screen, with a menu-driven interface and accurate, reliable temperature control, allowing operating status to be checked at any time;
- Compressor overheating and overload protection, plus a flashing display and audible alarms for high or low bath-fluid temperature and refrigeration-system overpressure;
- The open bath can serve as a pre-freezing or low-temperature bath. Glassware can be placed inside for constant-temperature experiments with acidic and organic solutions;
- The bath lid opens for real-time observation of the cooling liquid;
- 304 stainless-steel heat-exchanger tubing resists wear and vibration-induced breakage and is easy to clean and maintain;
- A magnetic front panel can be opened quickly without tools to clean dust from the condenser;
- The compact design accommodates laboratories with limited space;
- One recirculating chiller can cool multiple rotary evaporators simultaneously to meet cooling requirements, allowing multiple uses from one unit;
- An optional R485 communication interface allows computer display or export of experimental data, supporting data storage and playback;
Optional Accessories:
1. RS485/232 interface and communication software
