It is wrapped with moisture-proof film and a heavy-duty tarpaulin to protect against rain, dust, and mechanical damage.\r\nPrecision Components : Pressure regulators, flowmeters, and HMIs are packed in foam-lined, waterproof boxes with clear labeling. This prevents damage to delicate parts and simplifies identification during installation.\r\nAccessories : High-pressure hoses, filters, and spare parts are packed in separate labeled boxes, ensuring all components are accounted for upon delivery.\r\nShipping Methods :\r\nStandard Container Shipping : Uses 20GP (20ft General Purpose), 40GP (40ft General Purpose), or 40HQ (40ft High Cube) containers. This method is cost-effective, secure, and suitable for both sea and land transportation.\r\nCustom Shipping Solutions : For oversized models (e.g., 6000Nm\u00b3\/H), we coordinate with logistics partners to use flatbed trucks or bulk vessels, with additional reinforcement to secure the system during transit.\r\nLogistics Coordination : Our team provides detailed shipping documents (packing list, certificate of origin, customs clearance papers) and works with the user to confirm delivery schedules.

We also offer a fast spare parts supply service to minimize downtime in case of component failure.Traceability: Every CNG PRU is assigned a unique serial number, allowing for full lifecycle tracking of components and maintenance records.","report_certifications_image":[{"report_certifications_image-certification_image":5221},{"report_certifications_image-certification_image":5222},{"report_certifications_image-certification_image":5223},{"report_certifications_image-certification_image":5224},{"report_certifications_image-certification_image":5225},{"report_certifications_image-certification_image":5226}],"faq":[{"faq_-_question":"What is the difference between PRU and PRMS?","faq_-_answer":"PRU (Pressure Regulating Unit) and PRMS (Pressure Regulating Metering System) are the two designations for the skid-mounted CNG pressure regulating system on this page. The distinction is the metering function: a PRU focuses on reducing high-pressure pipeline gas to the required outlet pressure, while a PRMS adds integrated flow metering (turbine or mass flow meter) for accurate, auditable delivered-volume measurement \u2014 useful for billing and monitoring. Both share the same core integration of regulation, filtering, emergency shut-off and safety release."},{"faq_-_question":"What inlet pressure and flow rate can the PRU \/ PRMS handle?","faq_-_answer":"The standard configuration handles an inlet pressure of 250 bar (CNG) and a flow range from 200 Nm\u00b3\/h up to 6,500 Nm\u00b3\/h, with an end-use outlet pressure of 1\u201310 bar (typical outlet 2\u20134 bar). Larger or smaller flow rates can be customized on request. The first stage uses an international-brand regulator for stable, multi-stage (up to 3-stage) decompression."},{"faq_-_question":"What safety features and automation options are included?","faq_-_answer":"Safety is built into the skid: a high-pressure emergency shut-off valve (ESDV), safety pressure release, filtration, and interlock control of pressure, temperature and ESDV. For automation, optional PLC automatic control and HMI provide real-time visualization and allow unattended, safe operation. Core regulators and valves use international-brand components for proven reliability and global spare-parts support."}],"specification_image_paths":"","pdf_file_paths":null,"video_links":null,"type":"CNG Pressure Regulating (PRU \/ PRMS)","material":"Others","working_pressure":"4bar-250bar","capacity":"200Nm3-6500Nm3","medium":"Compressed Natural Gas","standards_certifications":"other standards & certifications","application_scenario":"Energy"},"_links":{"self":[{"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/product\/5228","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/types\/product"}],"acf:attachment":[{"embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/media\/5220"},{"embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/media\/5219"},{"embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/media\/5218"},{"embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/media\/5217"},{"embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/media\/5216"},{"embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/media\/5215"},{"embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/media\/21182"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/media\/21182"}],"wp:attachment":[{"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/media?parent=5228"}],"wp:term":[{"taxonomy":"application","embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/application?post=5228"},{"taxonomy":"category-type","embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/category-type?post=5228"},{"taxonomy":"capacity","embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/capacity?post=5228"},{"taxonomy":"certifications","embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/certifications?post=5228"},{"taxonomy":"energy","embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/energy?post=5228"},{"taxonomy":"medium-industrial-gas","embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/medium-industrial-gas?post=5228"},{"taxonomy":"industrial-gas-equipment","embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/industrial-gas-equipment?post=5228"},{"taxonomy":"inspection-agency","embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/inspection-agency?post=5228"},{"taxonomy":"material","embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/material?post=5228"},{"taxonomy":"product-category","embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/product-category?post=5228"},{"taxonomy":"products","embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/products?post=5228"},{"taxonomy":"related-products-group","embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/related-products-group?post=5228"},{"taxonomy":"working-pressure-range","embeddable":true,"href":"https:\/\/sinocleansky.com\/fr\/wp-json\/wp\/v2\/working-pressure-range?post=5228"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
