LBT-5S Geosynthetic Fabric Programmable Vacuum Degassing Constant-Temperature Water Processor

Description

Product Introduction:

This unit is a dedicated system for treating the water source in hydraulic tests of geosynthetic materials, or it can be connected via hoses to other geosynthetic‑related equipment. It effectively removes dissolved gases—including oxygen and carbon dioxide—from the water, providing degassed water essential for testing. In addition, it maintains a constant water temperature, serving as a thermostatic heat source to create a controlled environment with uniform, stable temperatures, enabling users to conduct constant‑temperature tests on test specimens or finished products. For example, the water used in vertical permeability tests of geotextiles must comply with the requirements of “Determination of Dissolved Oxygen in Water—Iodometric Method” (GB 7489‑1987), using distilled water or filtered clean water. Prior to geohydraulic testing, the water must be degassed by vacuum extraction or boiling, and its dissolved oxygen content must not exceed 10 mg/kg. This unit ensures that the water quality meets the specified test criteria.

Product Features:

It employs constant‑temperature vacuum degassing technology to powerfully remove dissolved gases such as oxygen and carbon dioxide from water. Equipped with an integrated dissolved‑oxygen sensor for real‑time online monitoring, it provides crystal‑clear visibility into water purity, delivering stable, bubble‑free, high‑precision deaerated water for hydraulic experiments and ensuring the reliability of experimental data right at the source. Compared with traditional heating‑and‑boiling methods that can take several hours, this unit completes degassing in just 10–15 minutes, boosting efficiency by a factor of dozens and truly meeting modern laboratories’ needs for “safe, rapid, and continuous” water supply. The entire operation is managed by microcomputer‑based intelligent control, featuring automatic judgment, autonomous operation, and built‑in protection, significantly reducing manual intervention for greater safety and peace of mind.

Technical Specifications:

Reference standards: GB/T 14799-2024, GB/T 17634, JTG 3460, SL 235, ISO 12956
