RF-391 Large SF₆ Recovery Unit
The RF-391 Large SF₆ Recovery Unit is designed for comprehensive gas handling services in SF₆ electrical equipment and switchgear chambers. It integrates multiple functions including vacuum pumping, gas recovery, refilling, cylinder pressurization, and vaporization output. During vacuum pumping, the PLC display shows real-time vacuum level changes. Recovered gas can be stored in tanks or external cylinders, with refilling options including direct filling (direct filling, pressure-regulated output) and pressurization (gas pressurization, liquid pressurization). The unit complies with DL/T 662 standards and features a semi-enclosed protective structure, modular design, complete functionality, reliable quality, easy maintenance, user-friendly operation, and an aesthetically pleasing appearance. It is suitable for various SF₆ gas recovery scenarios and widely used in power systems.
RLHJ68 H₂ Purification Unit
The RLHJ68 H₂ Purification Unit is a patented separation technology-based equipment designed to remove impurity gases (O₂, N₂, CO₂) from H₂. It addresses the limitations of conventional H₂ purging methods in hydrogen-cooled generators that fail to maintain high purity levels, achieving H₂ purity above 99%.
IRM200 Series Diffusion-type Infrared R134a Sensor
The IRM200 Series Diffusion-type Infrared R134a Sensor is based on NDIR (Non-Dispersive Infrared) technology with single-light-source dual-wavelength measurement. It adopts high-end infrared light sources and detectors, and uses gold-plated components as optical reflectors to improve measurement accuracy and stability. The proprietary compensation technology enhances environmental adaptability. It is widely used in smart homes, food processing, cold chain logistics, HVAC systems, industrial refrigeration, food storage/transportation, and leak detection applications.
RF-MG Series Hybrid Insulating Gas Mixing & Filling System
The RF-MG Series is a multi-functional, high-flow, high-precision gas mixing and filling system for electrical equipment. Featuring modular design for easy integration, it supports various configurations for different field requirements. It is suitable for type tests of primary equipment in switchgear factories, commissioning/maintenance of new substation equipment, and routine operations involving SF₆/N₂ or SF₆/CF₄ gas mixtures.
PEM Water Electrolysis H₂ Generator
This system utilizes advanced PEM electrolyzers for H₂ production, offering safer and more efficient operation compared to traditional alkaline electrolysis. It adapts well to renewable energy fluctuations. With three-tower TSA purification, it achieves 99.999% H₂ purity and -65°C dew point. Ideal for H₂ power generation, H₂ refueling stations, and semiconductor industries.
Mobile GIS Cleanroom Maintenance Shelter
Designed for critical power maintenance scenarios, this shelter integrates dust-free temperature control, smart monitoring, and high mobility. Its multi-stage air filtration and ISO-certified sealing prevent contamination, while intelligent climate control ensures stable conditions. Equipped with dual monitoring (environment/equipment status), self-lifting chassis, and rapid deployment capability, it provides efficient GIS maintenance solutions.
SF₆ Recycling and Treatment Center
The fully automated SF₆ digital management system incorporates digital twin technology, deep purification, and automated cylinder handling/storage. It enables contactless SF₆ processing including recovery, purification, testing, filling, and cylinder logistics across large-scale treatment centers.
