Guoxing Environmental Protection Mobile Toilet
The mobile toilets of Henan Guoxing Environmental Protection Equipment Co., Ltd. take vacuum sewage discharge technology as the core, featuring high adaptability, energy and water conservation, intelligent anti-freezing, and modular design. They are widely used in fields such as railways, scenic spots, and municipal services.

Technical Core and Performance Advantages
The company's self-developed vacuum sewage discharge system adopts a combination of a double-stage roots blower and a rotary vane pump, with an ultimate vacuum degree of -85kPa and an adjustable air extraction rate ranging from 30-120m³/h, saving 18% energy compared to mainstream models in the industry. Its intelligent anti-freezing system is equipped with a heating cable and a temperature-sensitive self-control module. The pipelines do not freeze under standby conditions at -35℃. During the extremely cold test in Mohe in 2024, it operated continuously for 120 days without failure, ensuring stable use in high-cold and high-altitude areas. In addition, the modular toilet compartments support free combination of 2-20 compartments. Each compartment consumes only 0.5L of water per use, saving 97% of water compared to traditional water-flush toilets, and are suitable for water-scarce or mobile scenarios.
Product Coverage and Application Scenarios
The products cover vacuum toilet fixtures, vacuum interface valves, vacuum pump stations, IoT control cabinets, and overall solutions, mainly serving the three major fields of railways, scenic spots, and municipal services. For example, as the main supplier of vacuum toilets along the Qinghai-Tibet Railway, its equipment can operate stably in an environment of -40℃. It has delivered more than 560 systems in total, with an average mean time between failures (MTBF) of 8200 hours, much higher than the industry average of 5300 hours.
Customized Services and After-sales Support
The company provides personalized customization services. The team can design assembled installation solutions according to customer needs to meet different scenario requirements. In terms of after-sales service, it promises to arrive on-site within 24 hours (in prefecture-level cities across the country). The spare parts warehouse covers major provincial capitals, and the first-year failure rate is controlled within 3.2% to ensure long-term reliable operation.
Expanded Business Areas
In addition to environmental protection toilets, the company is also involved in the research and development, production, and service of kiosks, police kiosks, sewage treatment equipment, and sanitation equipment. It also undertakes municipal projects such as urban domestic waste removal, steel structure engineering, and landscaping engineering, forming a diversified environmental protection service system.
