LBT-5 Geosynthetic Fabric Programmable Degassing Constant-Temperature Water Processor (50 L)

This unit is a dedicated device for water‑source treatment in hydraulic testing of geosynthetic materials. Connected via flexible hoses to other geosynthetic testing equipment, it effectively removes dissolved gases—such as oxygen and carbon dioxide—from the water, providing degassed water essential for testing. It also maintains a constant water temperature, serving as a thermostatic heat source to create a controlled, uniformly stable thermal environment for users, enabling constant‑temperature testing or evaluation of test specimens and manufactured products. With rapid heating and cooling capabilities, this machine significantly enhances the efficiency of water‑treatment tests, making it an ideal degassing‑water processor for geotechnical material laboratories.

LBT-5 Geosynthetic Fabric Programmable Degassing Constant-Temperature Water Processor (50 L)

Description

Product Introduction:

This unit is a dedicated device for water‑source treatment in hydraulic testing of geosynthetic materials. Connected via flexible hoses to other geosynthetic testing equipment, it effectively removes dissolved gases—including oxygen and carbon dioxide—providing degassed water essential for testing. It also maintains a constant water temperature, serving as a thermostatic heat source to create a controlled, uniformly stable thermal environment for users, enabling constant‑temperature testing or evaluation of test specimens and manufactured products. With rapid heating and cooling capabilities, this machine significantly enhances the efficiency of water‑treatment tests, making it an ideal degassing‑water processor for geotechnical material laboratories.

Product Features:

1. The environmentally friendly compressor employs fluorine-free, eco‑friendly refrigeration technology, offering advantages such as energy efficiency and environmental protection. The system is equipped with multiple protective devices, including safeguards against overheating, overcurrent, phase sequence errors, high pressure, low pressure, low refrigerant level, excessive temperature, and elevated ambient temperature.

2. Microcomputer-based intelligent control, simple operation, excellent temperature stability, with upper and lower limit over-temperature alarms, and PID automatic control. Features a large‑screen LCD display that conforms to international standards, along with a variety of functional indicator icons for clear, instant readability.

3. The microcomputer can correct deviations in temperature measurements, with a temperature correction accuracy of 0.1°C.

4. The user‑defined PID parameters are adjustable, and the system features automatic PID tuning.

5. Equipped with dual temperature sensors, the instrument automatically deactivates its cooling function when the operating temperature exceeds the ambient temperature by 5°C. This significantly enhances energy efficiency while extending the compressor’s service life, making it a cutting-edge, energy-saving product.
