Overview
DLSB-15000 chilled down water circulating pump is a equipment produced by GREATWALL, which is mainly used to provide constant current and constant pressure circulating chilled down water for various instruments and equipment to meet their low temperature conditions. The equipment has a liquid storage tank volume of 200L, a Temperature range of 10~ 25 ℃, and a temperature Stability of +/- 2 ℃. It is suitable for working conditions with Ambient Temperature 5~ 25 ℃ and relative humidity ≤ 60%.
Features
1. Temperature control using PID mode, high control accuracy.
2. The water temperature display adopts digital liquid crystal display with an accuracy of 0.1 ° C.
3. Water temperature and Water Flow rate can be adjusted as needed.
4. With Flow rate alarm protection function, avoid affecting the operation rate of cooling equipment due to insufficient Flow rate of circulating water for a long time.
5. Refrigeration Compressor using brand products, low failure rate, long life.
6. With multiple safety protection, including delay, overcurrent, overheating, Flow rate alarm, high and low pressure protection.
Principle
The device drives the refrigeration cycle through the built-in scroll Compressor, and uses the refrigerant (R22) to absorb heat in the system, thereby reducing the temperature of the domestic circulation water in the reservoir. The PID Temperature Control system precisely adjusts the refrigeration output according to the feedback of the Pt100 temperature sensor, while the circulation pump transmits the thermostatic chilled down water to the external device at an adjustable Flow rate and pressure (maximum Flow rate 116L/min, maximum pressure 2.8bar), and then returns the heat to the reservoir to form a closed-loop chill down cycle.
Applications
Electron Microscope (EM), X-ray machine, Laser, Mass Spectrometer, X-ray Diffractometer, Molecular Pump, Nuclear Magnetic Resonance, Accelerator, Vacuum Coating Equipment, Electron Beam Welding Machine, Ion lame plating, Material fatigue testing machine, low/high temperature test Chamber, Rotary evaporator, Reaction Kettle

Steps
The information does not provide specific operation steps.
Notice
• Equipment Ambient Temperature should be kept between 5 and 25 ℃.
Equipment working environment relative humidity should be less than 60%.
• Power supply voltage requirement is 3~ 380V/50Hz.
• The external circulation interface is DN25 threaded connection, and attention should be paid to matching when installing.
• The weight of the whole equipment reaches 300kg, and the ground load-bearing and space need to be considered during installation (the space occupied by the refrigeration host is about 840 * 1270 * 1450mm).
• Tank opening dimensions is φ 400mm, please pay attention when operating.
• Please pay attention to whether the safety protection function of the device (such as Flow rate alarm) is enabled normally.
