3FT Multi-functional Fire Hydrant

Product Description

3FT Multi‑functional Fire Hydrant — Vacuum‑based Cold‑climate Fire‑protection Pipeline Protection Solutions

TEAC Industries’ 3FT Multi‑functional Fire Hydrant delivers comprehensive reliable performance for harsh low‑temperature outdoor fire‑protection projects. This upgraded hydrant features ductile iron body of QT500‑7 with internal components made of SUS304, manganese‑titanium alloy and other premium materials. It adopts original vacuum drainage principle, requiring no thermal insulation materials to prevent frost‑burst under extreme cold conditions. Integrated with multiple capabilities including impact‑proof & anti‑spray, pressure regulation and boosting, low‑temperature anti‑seizure, anti‑theft and remote monitoring management, it serves as a superior replacement for conventional fire hydrants.

With more than 13‑year specialized experience in vacuum anti‑freeze equipment development and full‑range custom‑adaptation capacity, we resolve prominent industry pain points such as fire hydrant freeze‑cracking, accidental water spraying and pressure insufficiency in cold regions. The hydrant avoids high‑cost traditional anti‑freeze solutions including electric heat tracing and insulation wrapping, greatly reducing long‑term operation and maintenance expenses. Every unit undergoes rigorous pressure‑resistance and low‑temperature validation tests to achieve stable, reliable performance, meeting multi‑sector procurement requirements. It is widely applied for new construction and renovation of indoor and outdoor fire hydrant systems in petrochemical, chemical, municipal construction, residential communities, logistics parks, airports, stations and manufacturing enterprises.

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.
