Efficient Design for Daily Lab Use

The Recirculating Chiller, -20°C to 80°C – Precision includes several features that improve efficiency and ease of use. The double service valve reduces refrigerant leakage, enhancing performance while protecting the environment. Additionally, the integrated air-cooled refrigeration system simplifies installation across various lab setups.

Routine maintenance is straightforward thanks to the removable condenser grill, while the use of eco-friendly refrigerants supports sustainable practices. The front display allows users to easily check pump pressure and monitor system operation in real time. A wide bath fluid inlet ensures simple, spill-free refilling, and removable casters offer mobility for flexible installation.

 

Advanced Control Options

This model supports precise temperature management through external sensor integration, allowing more accurate control of sample conditions. Furthermore, computer connectivity enables remote control and data processing via dedicated software. A built-in alarm output port ensures that operational issues are immediately flagged for user attention.

The bright VFD display provides clear visibility of all current settings, while real-time monitoring allows simultaneous display of current and set values. Adjustments during operation are seamless, and built-in calibration ensures that control remains consistent and highly accurate throughout each cycle.

 

Outstanding Safety Features

Safety is a top priority in every laboratory, and this chiller delivers robust protection for users and applications. An over-temperature alarm warns users of abnormal conditions or low fluid levels, helping maintain uninterrupted cooling performance. Moreover, the system includes protection against over-current and short circuits.

To avoid unintentional changes during operation, the controller lock function prevents input errors. In case of overheating, the compressor shuts down automatically to prevent damage. These safety mechanisms work together to ensure dependable, worry-free use.
