Product Features:
Anti-freeze heating, keeps running in winter (electric heating version): Built-in electric heater helps prevent CO₂ freezing during pressure reduction and throttling, allowing continuous welding without gas interruption.
Pressure and flow displayed together, easy to read: Optional 0–25 MPa high-pressure gauge, 0–1 MPa low-pressure gauge, 0–4000 psi and 0–25 L/min float flow meter, so you can see the remaining tank pressure and gas flow at a glance.
Brass valve body, sturdy and durable: Main body is brass, high pressure resistant and rust-proof, perfect for long-term workshop use.
National standard G5/8 interface, compatible with various bottles: Fits multiple types of CO₂ cylinders, easy to install and remove.
36V safe voltage (heating version): Clearly marked 'Power 36V, do not use 220V', making workshop electricity use safer.
Tiered specs, choose as needed: Basic dual-gauge version → heated version with flow meter → English export version, covering normal/low temperature and domestic/export needs.
Compact and lightweight, for welding machines: Small footprint for tank installation, doesn’t take up much workspace, great for pairing with MIG welders in bulk.
Export ready: English labels + psi dial + flow meter, multiple voltage versions, designed for overseas markets.

Random or no inspection at all — inconsistent pressure and sealing within a single batch.
- ✕Unknown Material Quality
Unclear material grades and untraceable sources create potential safety and hygiene risks.
- ✕Limited Customization, High MOQ
Standard products only, with limited colors, labels and packaging, and higher minimum orders.

Real Questions Buyers Ask
Browse frequently asked questions — product specs, OEM customization, wholesale terms, export logistics and compliance.
Can I order products under my own brand?
Absolutely. Private label and OEM manufacturing are core services of ours. We can print your logo, apply your packaging artwork and even customize cylinder colors, caps and flavor cards to match your brand identity.
What is the MOQ for a custom OEM order?
For fully customized Cream charger packaging, the MOQ starts at one 20-foot container, with mixed SKUs allowed. For large cylinders, the MOQ is typically 500 units per size for custom labels and one 20-foot container for fully custom-printed cartons. Your sales manager will confirm the exact figures for your project.
Which parts of the product can be customized?
- Logo and artwork printing on chargers and cylinders
- Gift box and master carton design
- Cylinder body color, cap and nozzle color
- Flavor selection and multilingual manuals
- Barcode/EAN labels and pallet marking
What artwork files do you need from us?
Please provide vector files in AI, EPS or print-ready PDF format in CMYK with all text converted to outlines. We supply the exact dieline templates and safe-zone guides so your designer can set the artwork up correctly.
Is there a minimum or maximum order quantity?
Regular wholesale orders start at 100 cartons per SKU, and there is no upper limit. Container orders (20ft or 40ft HQ) receive the best unit pricing, and mixed models or flavors are welcome.
Do you offer special pricing for distributors?
Yes. Pricing is tiered by order volume and partnership level, and qualified distributors receive annual rebates, marketing support and regional protection. Send us your target quantities and we will quote within 24 hours.
What payment terms do you accept?
For bulk production we accept T/T with a 30% deposit and 70% balance against the bill of lading copy, or an irrevocable L/C at sight. Sample and small orders can be paid via PayPal, Western Union or trade-assurance platforms.
Can I request samples before placing a bulk order?
Yes. Stocked samples are dispatched within 3 working days and usually arrive in 5 to 7 days by express. Sample and freight charges are refundable once the first bulk order is confirmed.
How long will it take to receive my bulk order?
For CIF terms, due to commodity inspection by customs, it usually takes 7 to 15 days to ship to your freight forwarder after production is completed. Total door-to-door transit is typically 25 to 40 days depending on the destination port.
Which shipping methods are available?
Bulk orders ship by sea as FCL or LCL; urgent small orders and samples can go by international express (DHL, FedEx, UPS). Rail transport is also available for certain European and Central Asian destinations.
How is nitrous oxide classified for transport?
N2O ships under UN 1070 as a Class 2.2 non-flammable, non-toxic compressed gas, with the applicable oxidizer (5.1) subsidiary handling requirements. All cartons, cylinders and pallets carry the correct dangerous-goods marks and labels.
Do you provide dangerous-goods shipping documents?
Yes. We supply the full document package, including SDS/MSDS, dangerous-goods declaration, IMO declaration, packing list, commercial invoice, certificate of origin and bill of lading, through qualified dangerous-goods forwarders.
What certifications do Ronghai products hold?
Our factories operate under ISO 9001 quality management and HACCP/FSSC 22000 food-safety systems, and the gas and pressure containers are produced under TPED and applicable international transport requirements. Full certificates are available from your sales manager.
Is your nitrous oxide genuinely food grade?
Yes. The gas is certified food additive E942 with a minimum purity of 99.95%, produced and filled under food-safety controls. Every production batch is tested for purity and moisture and comes with a batch COA.
Which documents can you provide for customs clearance?
- Certificate of origin and commercial invoice
- Packing list and bill of lading
- SDS/MSDS and batch COA
- Food-grade statement
- Health/free-sale and third-party inspection certificates where required
Are the steel cylinders certified for pressurized transport?
Yes. Cylinders are manufactured under the EU TPED framework for transportable pressure equipment and meet the applicable UN cylinder requirements; U.S.-bound shipments follow the relevant DOT transport provisions.
