Xylem Robotics vs Thompson Duke: Why the X4 Wins on Labor Efficiency
A fill-speed number tells you how fast a machine doses. It doesn’t tell you how many people it takes to turn that dose into a sealed, saleable cartridge. That’s where the Xylem X4 and Thompson Duke’s filling machines separate.
The Xylem X4 Automated Cart Filler & Capper sorts, fills, and caps 510-thread cartridges in one automated sequence, with one operator, at 1,500–1,800 finished units per hour. Thompson Duke’s IZR publishes a fill rate only, runs from loaded trays, and leaves capping to a separate stage. Its SVH needs an operator to step every fill.
If your labor problem is everything around the filler, not just the dose, the X4 removes more of it.
The Short Answer: The X4 Finishes More Work per Operator
Labor efficiency means saleable output relative to the people needed to produce it. On that measure, the X4 leads for three reasons:
- It delivers capped cartridges, not just filled ones. The X4’s rated output covers sorting, filling, and capping. The IZR’s published rate covers filling only.
- It runs with one operator. Xylem publishes a one-operator specification. Thompson Duke doesn’t publish an operator count for either model.
- It needs no trays or jigs. The IZR fills from 252-cartridge trays, so every run starts with tray loading.
Xylem also publishes the specifications buyers need to verify these claims: fill accuracy, temperature range, utilities, footprint, and cost per unit. Thompson Duke publishes none of them for the IZR or SVH.
Feature Matrix: Labor Efficiency Side by Side
The table uses each manufacturer’s published specifications. “Not published” marks information the manufacturer doesn’t provide.
| Criteria | Xylem X4 | Thompson Duke IZR | Thompson Duke SVH |
|---|---|---|---|
| What a counted unit is | Sorted, filled, and capped cartridge | Filled cartridge only | Filled cartridge only |
| Published output | 1,500–1,800 units per hour (about 1,650 typical) | 30+ fills per minute; no hourly figure | Roughly 25 fills per minute with a skilled operator and consistent formula; lower for multi-SKU runs |
| Steps left outside the machine | Downstream inspection and packaging | Tray loading, separate capping, inspection, packaging | Operator steps each fill, plus capping, inspection, packaging |
| Operators | One | Not published | Not published; operator steps every fill |
| Capping | Integrated, about 3 seconds per unit; press, click, and screw closures | Not included; separate equipment | Not included |
| Trays or jigs | None | Required (252-cartridge trays) | Not published |
| Fill accuracy | 0.25% weight deviation or less | Not published | Not published |
| Fill temperature | 38°C–95°C | Not published | Not published |
| Operating cost | About 1 cent per packaged unit | Not published | Not published |
| Utilities and footprint | 120V, 11A; 70–90 psi @ 4.6 CFM; 10 × 10 ft working space | Not published | Not published |
Completed Output Beats Fill Rate
A filled cartridge isn’t finished. It still needs capping, and often a move to another station, before it can be inspected and packed. Every one of those handoffs adds labor.
The X4 closes that gap inside the machine. It sorts, fills, and caps in one sequence, capping each unit in about 3 seconds, so cartridges leave the X4 sealed.
The IZR’s published rate stops at filling. Its product page doesn’t include capping, and Thompson Duke sells a separate TPM mouthpiece press for that step. That means a second machine, a second station, and a handoff between them. The IZR’s 30+ fills per minute and the X4’s 1,500–1,800 units per hour don’t measure the same thing. Only the X4’s number describes a sealed cartridge.
Fewer Hands Around the Machine
One Operator for the Whole Sequence
The X4 is specified for one operator across sorting, filling, and capping. That gives a production manager a defined staffing number to plan around.
Thompson Duke doesn’t publish an operator count for the IZR or SVH. A buyer has to discover the real staffing requirement after installation, once tray loading, the separate capping station, and handoffs are in place.
No Tray Loading
The X4 runs without trays or jigs. The IZR fills from 252-cartridge trays, so hardware has to be staged into trays before every run, and filled trays have to be moved on to capping afterward. That pre-staging is labor that never shows up in a fills-per-minute figure.
No Operator-Stepped Filling
The SVH is a semi-automatic, vertical hand-fill machine, and Thompson Duke states that each fill is stepped by the operator. Its rate of roughly 25 fills per minute assumes a skilled operator running a consistent formula. Thompson Duke also notes that multi-SKU production typically averages lower because of changeovers. Output rises and falls with the person running it. The X4 takes that variable out of the process.
Accuracy and Product Protection You Can Verify
The X4’s pumps are accurate to 0.25% weight deviation or less, a number your quality team can check during validation. Thompson Duke doesn’t publish a fill-accuracy figure for either model.
The X4 can fill at temperatures as low as 38°C, giving processors room to protect terpene profiles. Distillate runs typically operate around 60°C, and the full range runs to 95°C. Thompson Duke doesn’t publish fill temperatures for the IZR or SVH.
The X4’s resin path is hermetically sealed and can be temperature- and chemically sterilized, and Xylem specifies an indoor lab or GMP ISO 9 or above operating environment. Those are documented design points a quality team can build procedures around.
Cost and Setup You Can Plan Around
Xylem lists the X4’s operating cost at about 1 cent per packaged unit. Thompson Duke doesn’t publish an operating cost for either model, and a full comparison would also need to add the cost of separate capping equipment for the IZR.
The X4’s site requirements are published too: 120V, 11A power, compressed air at 70–90 psi @ 4.6 CFM, and a 10 × 10 ft working space. Thompson Duke doesn’t publish utilities or footprint on its model pages.
Xylem also provides commissioning, installation, and on-site operator training, either at your facility or at its Houston location, plus remote support by video. Your team learns to run, clean, and change over the X4 before production starts.
When you request quotes, ask every vendor to itemize:
- The full configuration needed to produce a capped cartridge
- Any separate capping or packaging equipment
- Trays, tooling, and closure compatibility
- Installation, training, and service
- Cleaning procedures and changeover time
- Utility and floor-space requirements
- Staffing for loading, operation, capping, and pack-off
The Verdict
For operations where labor is the constraint, the Xylem X4 is the stronger choice. It turns sorting, filling, and capping into one automated sequence run by one operator, delivers 1,500–1,800 sealed cartridges per hour, holds pump accuracy to 0.25% weight deviation or less, and runs without trays or jigs.
Thompson Duke’s IZR stops at filling and depends on trays and separate capping equipment. Its SVH depends on an operator stepping every fill. Neither model publishes the accuracy, staffing, or cost figures you’d need to plan a line around it.
Confirm the result on your own floor. Run the X4 with your oil, hardware, fill volume, and staffing, and count finished cartridges, not fills.
