Cooling circulator Chiller LX -0400

Overview

The Cooling Circulator Chiller LX-0400 is a recirculating cooling system engineered to deliver precise temperature control across laboratory and industrial processes. Combining refrigeration technology, microcomputer control systems, and precision components in a single unit, it is intended to maintain stable temperatures for connected equipment, reactors, or samples. The closed-loop design circulates a temperature-controlled fluid through the process, helping to keep operating conditions consistent throughout a run.

Performance and Specifications

The LX-0400 provides a rated cooling capacity of 400W and operates across a temperature range from -25℃ up to room temperature, making it suitable for applications that require sub-ambient cooling. Its integrated pump delivers a maximum flow of 20L/min at 1bar, supporting reliable circulation through the connected system via DN20 connection ports. The 25L tank capacity provides a working reservoir for the circulating fluid.

• Cooling capacity: 400W
• Operating temperature range: -25℃ to RT
• Pump max: 20L/min; 1bar
• Cooling capacity at temperature: 2.4kW at 0℃, 1.5kW at -10℃, 0.8kW at -20℃
• Tank capacity: 25L
• Connection port: DN20
• Dimensions: 400 × 600 × 1150 mm
• Power supply: 220V 50Hz, 1 phase, 2.2kW max
• Refrigerant: R449A

The graded cooling figures indicate how available capacity varies with setpoint: 2.4kW is available at 0℃, decreasing to 1.5kW at -10℃ and 0.8kW at -20℃. This allows users to match the unit to the thermal load expected at their target temperature. The chiller uses R449A refrigerant and draws from a single-phase 220V supply, with a maximum power consumption of 2.2kW.

Typical Applications

The LX-0400 is well suited to applications that require steady, sub-ambient temperatures, including reactor jacket cooling and the removal of process heat. It is commonly paired with jacketed glass reactors where temperature regulation is critical. For example, it can supply cooling to a exothermic reaction setup, helping to keep the process within the intended temperature window. It can also support a controlled synthesis workflow that depends on consistent jacket temperatures throughout the procedure. Smaller setups, such as a TOPT-1L Glass Jacketed Reactor (Double glass reactor), can also be connected through the DN20 ports for circulating cooling.

Design and Construction

With a footprint of 400 × 600 × 1150 mm, the unit is configured as a floor-standing chiller for laboratory and process environments. Microcomputer-based control supports precise temperature management, while the DN20 connection ports and 20L/min pump enable straightforward integration with reactors and other temperature-sensitive equipment. The 25L tank capacity provides a sufficient fluid volume for stable circulation, helping to dampen temperature fluctuations during operation.
