Product Description
Pipe Anti‑freeze Hydrant — Vacuum‑based Cold‑climate Pipeline Protection Solutions
TEAC Industries’ Pipe Anti‑freeze Hydrant delivers dependable freeze‑proof performance for outdoor low‑temperature water supply projects. This manually‑operated hydrant adopts the original vacuum‑siphon drainage principle, requiring no thermal insulation materials and protecting pipelines against frost‑burst damage even under extreme‑50 °C conditions. Available in nine standard sizes from DN15‑DN80, it supports customizable installation height ranging from 1000 mm to 3500 mm, with simple manual operation for water intake and automatic anti‑freeze drainage.
With more than 13‑years of specialized experience in vacuum anti‑freeze equipment development and comprehensive customization capabilities, we resolve the long‑standing pain point of pipeline frost cracking in cold‑climate regions. The hydrant replaces high‑cost conventional anti‑freeze solutions including electric heat tracing, insulation wrapping and continuous running‑water anti‑freezing, effectively cutting long‑term operation and maintenance costs. Every unit undergoes rigorous pressure‑resistance and low‑temperature qualification tests to guarantee stable, leak‑free service, meeting multi‑industry procurement demands. Simple operation logic: open the hydrant for water supply; upon closure, vacuum siphon automatically drains residual inside‑pipe water to avoid pipe damage resulting from frost expansion. It is widely deployed for outdoor and non‑heated water supply pipelines in municipal, petrochemical, landscaping, agricultural and rural fields.
What is Fluid Vibration Frequency Superposition Sub-Dynamic Technology?
Fluid Vibration Frequency Superposition Sub-Dynamic Technology is an innovative technology developed by integrating aerodynamics and fluid mechanics. It forms the SK Fluid Dynamic Module Vacuum Assist System, which as a whole meets internationally advanced technical standards and is specifically designed to address industry challenges such as low-temperature freezing and blockages in water supply pipes, poor drainage, and hydrodynamic energy losses.
The entire system is divided into four consecutive operational stages—aggregation, ejection, bursting and secondary propulsion—each of which amplifies the fluid’s efficacy:
1. Aggregation | Dynamic Design
Through the dynamic angular design of a specialised impeller structure, the optimal operating range is identified, maximising the aggregation of water molecule bubbles within the pipeline and laying the groundwork for subsequent energy release.
2. Ejection | Vibration Frequency Range Design
Relying on a dynamic blade structure, the system precisely matches the optimal amplitude and vibration frequency range for water molecule bubbles, applying force to the aggregated bubbles to achieve their directional ejection.
3. Bursting | Burst Rate Design
Under the continuous dynamic force of the vibration frequency, the ejected bubbles achieve maximum bursting of water molecule bubbles, fully releasing the vibrational energy and creating a vacuum-assisted effect.
4. Secondary Kinetic Energy | Utilisation Study
The utilisation of the energy saved through the bursting process is optimised, converting the energy released by the bursting bubbles into secondary kinetic energy within the pipeline. This drives the movement of the fluid inside the pipe, achieving a vacuum-assisted drainage effect.
