    Description

    The YR06705 Recirculating Chiller is a robust and highly efficient solution for processes requiring rigorous thermal control. Designed with a forced-air cooling system and using the environmentally friendly refrigerant R410A , this unit guarantees a cooling capacity of 1500 W. Its architecture is designed for integration into environments where stability is critical, offering an adjustable range of 5 °C to 40 °C with exceptional accuracy of Â±0.2 °C . Thanks to its PID control , the device optimizes energy consumption while maintaining constant airflow, ideal for protecting heat-sensitive equipment.

    Design and Technology (Functionality)

    The YR06705 stands out for its high-performance pump capable of delivering a maximum flow rate of 40 L/min and a pressure of 0.14 MPa, ensuring smooth recirculation even in circuits with some resistance. Its 5-liter tank is designed to work with water or 15% ethylene glycol mixtures, preventing freezing in low-temperature applications. Furthermore, its compact design prioritizes operational safety, integrating overload and overheat protection systems, as well as liquid level sensors that shut down the unit in case of any malfunction.

    Frequently Asked Questions

    • What type of fluid should I use if I work at temperatures below 10°C?
    The use of a 15% aqueous ethylene glycol solution is strongly recommended to prevent ice formation and protect the integrity of the pump.
    • Is it suitable for environments with sub-zero temperatures?
    The equipment operates ideally at an ambient temperature of 25°C. For use in regions with extreme sub-zero temperatures, it is essential to consult our technical service to make the necessary adjustments.
    • What level of noise does it generate in the laboratory?
    The unit emits a noise level of 68 dB, which is standard for high-power industrial chillers with forced ventilation.

    Advantages and Disadvantages

    Advantages
    • Superior Thermal Accuracy: Thanks to its advanced PID Control , the equipment maintains a thermal stability of Â±0.2 °C , ensuring that sensitive processes do not suffer critical deviations.
    • Comprehensive Safety System: Includes multiple automatic protections against overload, overcurrent, overheating, and anomalies in pressure or liquid level, which prolongs the life of the equipment and protects your investment.
    • High Flow Capacity: With a maximum flow rate of 40 L/Min , it is capable of meeting the cooling demands of high-performance industrial and laboratory equipment.
    • Fluid Versatility: Its design allows it to operate efficiently with both water and 15% ethylene glycol solutions, expanding its application range in different climates and technical needs.
    • Ecological Refrigeration: Uses R410A refrigerant , meeting modern standards of energy efficiency and respect for the environment.
    Disadvantages
    • Noise Level Management: Its noise level of 68 dB is noticeable in quiet office environments, so it is recommended for installation in ventilated areas or spaces designed for machinery.
    • Space Requirements: To ensure efficient forced air cooling, you need a clearance of at least 1 meter in front and in height, which should be taken into account when planning the laboratory layout.
    • Environmental Sensitivity: Not suitable for operation in locations with high condensation or extreme humidity, as this could compromise the electronic components of the outer panel.

    Product Use in the Field

    The YR06705 Recirculating Cooler is widely used for cooling rotary evaporators , mass spectrometry systems, and industrial lasers that generate constant waste heat. In medical settings, it is crucial for maintaining the temperature of diagnostic imaging equipment. Its ability to maintain a flow rate of 40 L/min makes it ideal for applications requiring rapid heat dissipation in continuous 24-hour operating cycles.

    Maintenance and Usage Recommendations

    1. Location: Install the cooler in a dry location with at least 1 meter of free space around the ventilation panels to prevent overheating of the compressor.
    2. Fluid Cleaning: Change the heat carrier periodically to prevent the accumulation of sediment that may obstruct the inlet/outlet diameter (Rc 1/2).
    3. Electrical Monitoring: Ensure you have a stable 220-240V power supply, as fluctuations can affect the accuracy of the PID control.
