If you’re sourcing cream chargers in multiple sizes—from 8g cartridges to 3.3L tanks—you may be wondering: Can one factory actually handle all of these at once? Or do you need to work with multiple suppliers, each specializing in just one type?
At nitronovae, we’ve optimized our five production lines to handle all major N2O tank formats—including 8g,640g, and 3.3L cylinders—without delays, mix-ups, or quality inconsistencies.
Here’s what you need to know when sourcing different tank sizes from a single OEM partner.
1. Why Do So Many Factories Specialize in Just One Size?
Most small or mid-sized factories build equipment focused on only one tank form:
- A small punch-press line for 8g steel cartridges
- A blow-forming line for 640g steel tanks
- A welding and polishing line for refillable 3.3L cylinders
💡 The machinery, pressure testing systems, and even labeling equipment are totally different.
2. What It Takes to Handle All Tank Sizes in One Facility
| Requirement | Why It’s Critical |
| Multi-format forming lines | To shape both cartridges and cylinders efficiently |
| Modular testing systems | Burst, hydro, and pressure decay tests by tank class |
| Automated packaging options | Cartons, shrink wrap, trays for all sizes |
| Batch traceability across SKUs | To avoid flavor/format cross-contamination |
| Regulatory coverage (CE + TPED + FDA) | Different sizes = different compliance routes |
✅ At nitronovae, our factory is split into dedicated zones by tank type, but all share:
- Centralized quality lab
- Shared branding team for stickers, boxes, and QR
- Unified ERP system for inventory tracking
3. Benefits of Using One Factory for All Sizes
✅ Simplified communication: One export manager handles your entire order, from 8g samples to 3.3L accessories.
✅ Faster mixed-size production runs: E.g., ship 100,000 8g + 2,000 640g + 300 3.3L in one container, all under one invoice.
✅ Consistent branding: Cap colors, box layout, language localization, and label design stay on-brand across all SKUs.
✅ Cost savings on shipping and customs: Combine all SKUs in one shipment to lower freight cost and reduce clearance complexity.
4. How MOQ and Lead Times Are Managed Across Sizes
| Tank Type | MOQ | Lead Time (standard) | OEM Options |
| 8g Steel | 100,000 pcs | 7–10 days | Color caps, box print |
| 640g Steel | 1,000 pcs | 10–14 days | Logo engraving, custom valve |
| 3.3L Cylinder | 200 pcs | 14–18 days | Custom handle, refillable type |
🧠 You can stagger shipments or consolidate all SKUs into a single container. We support:
- Mixed pallet layout diagrams
- Unified expiration and batch coding
- Combined certification files (TPED, CE, FDA)
5. Do Different Sizes Require Separate Certifications?
Yes, and it’s important your supplier provides correct docs for each tank.
| Size | Required Docs |
| 8g | CE, FDA, MSDS |
| 640g | CE, FDA, TPED, Batch # |
| 3.3L | TPED (π mark), CE for valve, Hydro test cert |
📌 We generate a single export folder that includes all certificates by SKU, batch, and destination port.
6. When You Should NOT Combine Sizes in One Order
While it’s efficient to source everything together, you may want to separate sizes if:
- You’re targeting different countries with specific import rules
- You need flavored 8g but neutral 640g—requires different labeling rules
- You want to test market pricing and sell under multiple brands per SKU
💡 In these cases, we help by splitting your order into sub-branded shipments under one master booking.
Conclusion
Yes—one factory can handle all major cream charger sizes. But only if it’s built for scale, cross-format testing, and multi-channel distribution. At nitronovae, we’re proud to offer end-to-end compatibility across 8g, 640g, and 3.3L N2O tanks—with one point of contact and one synchronized brand experience.
