Product Features:

1. LQS-2003 Medium Low Temperature Cooling Circulating PumpOccupying minimal space and compact structure, it can be directly placed on a desktop or in a fume hood for use.

2. The regenerative temperature difference cooling control technology with adaptive temperature regulation is more energy-efficient.

3. Maintenance free pressure pump, long service life, pump pressure and flow automatically adapt to external loads, effectively protecting against damage from external loads.

4. The circulation function can be controlled independently or simultaneously with the cooling function.

5. Equipped with a glass level gauge, it can monitor changes in the liquid level in the tank in real time and is not prone to aging.

6. Stable and reliable system: High performance and high-quality spare parts with stable quality and reliable performance.

7. Multiple safety protections: condensation temperature protection, water tank temperature protection, refrigeration overheating and overcurrent protection, and can be alerted by both light and sound when an alarm is triggered.

8. When an alarm is triggered, both the light and sound will alert, and various alarm codes will be displayed directly to identify the error point.

9. NTC temperature sensor, capable of single point temperature calibration.

10. Multiple operation modes are available, and automatic recovery can be achieved in case of unexpected power failure, ensuring continuous supply of cooling circulating water.

11. Communication through RS485 DB9 interface, following MODBUS RTU protocol, facilitates remote control.

13. The operation panel has waterproof function and is equipped with a high brightness LED display screen, which not only provides a clear visual experience, but also ensures that it is not damaged even in water splashing environments.

14. Components that come into contact with the heat transfer medium, such as circulation pumps, connecting pipes, sensors, water tanks, cooling coils, water outlets, and return ports, are all made of corrosion-resistant materials.

15. Choose environmentally friendly refrigerants that have no destructive impact on the ozone layer, low greenhouse gas emissions, energy-saving and high-efficiency characteristics, and comply with relevant regulatory requirements to promote sustainable development.
