Short answer: These two sit at opposite ends of the premium hand-torch idea. The Herbert Arnold Zenit Hand Torch (reference price about $3,695) is a quiet, single-stage surface-mix hand torch built on Arnold’s silent Zenit principle: the burner head is separated from the control part and fed gas through flexible hoses, and it is aimed squarely at reworking borosilicate. The GTT Delta Elite (about $2,575 for the standard four-stud bench model, with a separate hand version priced apart) is GTT’s Triple Mix flagship, a 2-stage, 57-jet surface-mix torch offered as a bench or hand configuration. If you want a hushed, heavily built torch with one intuitive control for careful boro rework, the Zenit fits. If you want the widest flame range and chemistry from a single head and the option of hands-free fire switching, the Delta Elite fits. Below is how they actually differ.
If you are still deciding between a benchtop and a handheld setup in general, start with the bench vs hand torch guide; this article is the head-to-head between these two specific premium torches.
How each torch mixes gas
Both torches are fundamentally surface mix, meaning fuel and oxygen stay separate until they meet at or just past the face rather than blending inside the head. But they get there very differently. (For the underlying concepts, see surface mix vs premix torches.)
Herbert Arnold’s Zenit family uses a special flame-stabilizing system that lets the burner run with a surplus of air. Arnold’s own materials describe the result as a cooler, noiseless flame with a stable, tight-knit shape that adjusts from a sharp pin point to an intensive flame through a single twist grip. The Zenit line runs propane and oxygen (and can take compressed air), with dedicated hydrogen and oxygen versions offered for quartz. The hand torch is the concentric, single-stage member of that family, tuned for boro.
GTT’s Delta Elite is a Triple Mix torch. As GTT describes it, Triple Mix first surrounds the fuel with oxygen and then injects a second oxygen stream directly down the fuel stream, so the fuel burns more completely for a hotter, cleaner flame. The two oxygen streams are controlled independently by the green and blue valves, which is what lets one head cover a wide range of flame sizes and chemistries without swapping tips. The full mechanism is covered in the GTT Triple Mix technology guide. One point worth keeping straight: the Zenit’s air inlet and GTT’s blue valve are not the same thing. The Zenit blends air alongside oxygen and fuel through its stabilization system, while GTT’s blue valve adds a second injected oxygen stream. Both give control, by different means. (That comparison comes from a community discussion on Lampwork Etc. and is framed here as community knowledge, not a measured result.)
Head, handle, and build
The Zenit Hand Torch’s defining feature is that the burner head is separated from the control part, with gas fed to the head through flexible hoses. In practice that keeps the working head light and the valves back at the control body, which suits close, controlled rework of a piece in your hand. Community reports on Lampwork Etc. describe the Herbert Arnold as easy to adjust and heavily built, with strong control, though the same reports note it melts boro more slowly than a comparable GTT. Treat those melt-speed and build-feel impressions as community opinion rather than tested figures.
The Delta Elite packs a far denser burner face: 57 jets total, arranged as a 7-jet Lynx center fire inside 50 outer jets across three rings, and it is a 2-stage torch. In its hand configuration GTT puts a fast on/off switch on the handle so you can alternate between the inner and outer fire quickly. GTT torches are also self-adjustable across a broad range and pair well with a foot pedal for hands-free fire switching. The trade-off the community flags is ergonomic: as GTT torches grow, the number of small knobs grows with them, and larger models get harder to manage by feel. On a torch this size that is a real consideration, not a knock on the maker.
Fuel and oxygen: published versus estimated
This is where the two diverge most on paper, and where honesty about sourcing matters.
The Zenit Hand Torch runs propane and oxygen, with compressed air available through its stabilization system. Herbert Arnold does not publish an oxygen consumption figure or a jet count for this torch, so we do not state one. That is a limit of the published data, not a criticism of the torch; Arnold’s documentation focuses on the flame principle rather than a flow table.
GTT’s Delta Elite carries a catalog oxygen estimate of about ~30 LPM. That number is not a single published spec: it is derived from GTT’s own flow table at the largest usable flame on propane, with natural-gas consumption running roughly two and a half times higher. We label it an estimate on purpose. GTT torches are also not fuel-specific: the same model runs propane, natural gas, or hydrogen, which is a genuine flexibility advantage over a torch documented for propane and oxygen. Oxygen sizing on a torch this large is a real budget item; if you are working out supply, the borosilicate torch guide covers how demand scales with torch size.
Editor’s note: figures here come from the makers’ own pages and manuals where we have them, and are labelled as estimates where they are ours. Herbert Arnold does not publish oxygen or jet figures for the Zenit Hand Torch, and the Delta Elite oxygen figure is an owner-derived estimate from GTT’s flow table, not a single published number. Confirm current specs and configuration with the maker before you buy.
Flame behavior and glass
The Zenit’s whole design goal is a cooler, quieter, very stable flame. Running with surplus air gives a noiseless flame with a tight-knit shape, and the single twist grip takes it from a fine pin point up to an intensive flame. Arnold positions it specifically for reworking borosilicate, and the catalog reflects that: it is a boro hand torch. If your work is careful assembly, joins, and detail rework where a quiet flame and a heavy, controllable body help, that is the Zenit’s lane. A slower melt is part of the same trade: a gentler flame is more forgiving but takes longer on heavy boro.
The Delta Elite trades some of that quiet for range. GTT frames it as working soft glass, borosilicate, and quartz, and the independent oxygen valves produce a spread of flame chemistries from fuel-rich reduction through neutral, oxidizing, and over-oxidizing. That chemistry range, achieved without changing tips, is the practical payoff of Triple Mix, and it is why the Delta Elite reads as a flagship rather than a specialist. Where the Zenit is tuned for one job done quietly, the Delta Elite is built to cover many.
Price and configuration at the premium end
Both are premium torches, but the money lands differently.
| Herbert Arnold Zenit Hand Torch | GTT Delta Elite | |
|---|---|---|
| Reference price | ~$3,695 (pro band) | $2,575 (standard four-stud bench; hand version priced separately) |
| Mix | Surface mix | Surface mix (Triple Mix) |
| Stages | Single stage | 2-stage |
| Jets | Not published | 57 (7-jet Lynx center plus 50 outer) |
| Mount | Hand | Bench or hand |
| Oxygen | Not published | ~~30 LPM (estimate) |
| Fuel | Propane and oxygen (air available) | Propane, natural gas, or hydrogen |
Read the prices carefully. The Zenit Hand Torch’s roughly $3,695 is the price of the hand torch itself. The Delta Elite’s $2,575 is specifically the standard four-stud bench model on GTT’s product page; the Delta Elite hand-torch version has different controls and separate pricing that GTT does not consistently publish, so do not read $2,575 as the hand-torch figure. Compared like for like, hand torch against hand torch, the gap narrows from the headline numbers, and you should confirm the current hand-version price with GTT directly before budgeting.
Who each one is for
Choose the Herbert Arnold Zenit Hand Torch if a quiet, stable flame and a heavily built, easy-to-adjust body matter more to you than raw range. Its separated head and single twist grip suit careful borosilicate rework and assembly, and if you share a studio or simply dislike torch noise, a noiseless flame is a real quality-of-life gain. The costs are the higher hand-torch price and a slower melt on heavy boro, plus a maker who publishes less spec detail than GTT.
Choose the GTT Delta Elite if you want one head to cover the most ground: soft glass, boro, and quartz, a wide flame-chemistry range from the independent oxygen valves, fuel flexibility across propane, natural gas, and hydrogen, and a handle switch (or foot pedal) for fast, hands-free fire switching. The trade-off is more knobs to learn and a louder torch than the Zenit, and the honest caveat that the published price is the bench model, not the hand version you would compare against the Zenit.
For a broader look at torches chosen partly for a quiet flame, see the quiet glass torches guide. Whichever you pick, the manufacturer’s own manual governs setup, pressures, and the flashback protection your torch and gas supply call for; nothing here replaces it.
