How Does SF6 Gas Recovery Work and What Are Its Benefits?

2025-12-29

SF6 gas recovery is the process of extracting, purifying, and reusing sulfur hexafluoride (SF6) gas from electrical equipment like circuit breakers and GIS switchgear. This ensures that the gas is not released into the atmosphere, helping to reduce environmental impact. Wrindu offers state-of-the-art recovery systems that ensure high purity and compliance with environmental regulations.

What Is SF6 Gas Recovery?

SF6 gas recovery involves capturing and processing sulfur hexafluoride from high-voltage electrical equipment to prevent its release into the atmosphere. Wrindu specializes in providing mobile recovery units that efficiently vacuum, filter, and store SF6 gas. These systems achieve vacuum levels as low as 0.05 MPa, purify the gas by removing moisture and oils, and store it as liquid for future reuse.

This method supports the sustainable maintenance of electrical power systems for utilities and OEMs, reducing the need for new gas purchases and helping companies adhere to environmental regulations. Wrindu’s SF6 gas recovery units are designed for high-pressure liquefaction and can be integrated into substations and manufacturing lines. Key steps in the process include evacuation, filtration using molecular sieves, and compressing the gas to a storage pressure of 0.8 MPa.

Why Choose SF6 Gas Recovery Equipment?

SF6 gas recovery offers a range of benefits, from significantly reducing greenhouse gas emissions to cutting procurement costs. By using Wrindu’s advanced recovery systems, clients can lower their environmental impact while also improving cost-efficiency. These systems incorporate high-quality compressors and rotary vane pumps for leak-free operation, essential for industries like power grids and manufacturing plants.

Furthermore, global regulations like the Kyoto Protocol require the proper handling of SF6, making recovery a necessary part of maintaining compliance. Wrindu’s recovery units feature auto power detection and heated filters that enhance purification, making them ideal for B2B buyers seeking cost-effective solutions.

How Does SF6 Gas Recovery Benefit Manufacturers?

For manufacturers, SF6 gas recovery offers significant cost savings and efficiency improvements. Wrindu’s mobile recovery units are designed to allow manufacturers to reuse SF6 onsite, reducing downtime during switchgear production. This can result in up to a 50% reduction in costs compared to purchasing new SF6 gas.

The systems comply with IEC standards, helping factories avoid penalties while improving overall operational efficiency. Wrindu’s mobile trailers feature vaporization technology for quick refilling, enabling scalable operations for both exporters and utilities.

What Are the Key Components of SF6 Recovery Systems?

The key components of an SF6 recovery system include vacuum pumps, compressors, filters, and storage tanks. Wrindu’s recovery units are equipped with electric heating regenerators and solenoid valves for precise control. These systems ensure that the SF6 gas is purified to meet strict standards, with oil content maintained below 10 PPM.

Wrindu offers customizable storage tanks with capacities ranging from 100 kg to 280 kg, making these systems ideal for a variety of B2B applications, including testing labs and substations. The integration of advanced filtration technology ensures that the SF6 gas remains clean and suitable for reuse.

Which SF6 Recovery System Is Best for High-Voltage Switchgear?

For high-voltage switchgear, systems with large recovery capacities, like Wrindu’s FTHS-60 model, are ideal. The FTHS-60 is capable of recovering up to 60 m³/h of SF6 gas, with a final pressure as low as 0.03 MPa. This makes it perfect for handling the high demands of circuit breakers and GIS switchgear.

Wrindu’s range of SF6 recovery systems includes models tailored to different capacity needs, from smaller units like the FTHS-15 to larger models like the FTHS-60. Each model is designed for specific applications, ensuring that clients can choose the best system for their requirements.

Model Capacity (m³/h) Power (kW) Storage (kg)
FTHS-15 15 12 180
FTHS-30 30 18 280
FTHS-60 60 22 280+

These units are CE-certified and reliable for industries such as power plants and railway systems, providing tailored solutions for high-voltage electrical systems.
