Diesel is still the Uptime default. Gas and LPG are the right call when the pipeline is reliable, run hours are long, or the grid interconnect is years out.
Most Tier III and Tier IV halls still spec diesel so fuel sits on the plot and does not depend on a gas utility. Natural gas fits bridge and prime duty, and many standby sites with a stable pipeline. LPG fits edge halls with no pipe. Yuyang does not sell diesel data-center sets. We spec natural gas and LPG from 150 kW to 1.4 MW, paralleled for N+1.
Diesel needs a tank on the plot. Gas and LPG depend on supply — pipeline gas or delivered LPG inventory.
Reference only — not a Yuyang SKU
Tank on plot, zero gas dependency
When to use
Spec is locked to on-site fuel, or the local gas utility has reliability problems of its own.
When not to
You want lower NOx and particulates, or would rather skip a tank farm and a fuel-polishing program.
Yuyang factory spec
Reliable pipeline, long run hours
When to use
The pipeline is stable and you need bridge or prime duty, or standby with lower emissions than diesel.
When not to
There is no gas utility on site and running one in is not realistic.
Yuyang factory spec
Edge site, no pipeline
When to use
The site has no pipeline — edge halls, cable landings, remote builds — and bottled or bulk LPG can be staged.
When not to
Runtime needs to outlast whatever LPG inventory the plot can store.
Dual-fuel, only if the site needs it. Some owners want a diesel-style start with gas runtime. We configure that against a load list — it is not a catalog SKU.

What we build
What we build
Natural gas and LPG generator sets, ATS-ready, parallel-ready. Open, container, or low-noise. High-ambient and coastal packages on request. We do not keep 2–4 MW diesel, HVO, or battery-only plants in this line.
Natural Gas
350 kW gas generator with a Cummins natural gas engine, soundproof canopy, and SmartGen controller. For factory backup, job sites, and commercial power.
LPG
Efficient 300kW LPG generator delivering clean, reliable power for industrial and commercial use. Supports dual-fuel supply and multi-unit parallel operation.
Short answers. The table above is the full comparison. Request a quote →
Yes, when the pipeline is reliable or you are running bridge/prime for months. The UPS covers start. It is a poor swap if the spec requires on-site fuel with no gas service.
No. We spec natural gas and LPG. If the bid is diesel-only, we will pass rather than stretch the catalog.
Pipeline gas runs as long as the utility gas stays up. LPG runs as long as bulk or bottle inventory. Diesel runs as long as the tanks and the polishing plan.
Often yes at edge and remote sites. Local storage and setback rules still apply. Send the plot constraints with the load list.
Configured on request. It is for sites that want a diesel-like start with gas runtime, not a default package.
Tell us IT kW, cooling or PUE if you have it, natural gas or LPG, N+1 or 2N, and whether this is standby or bridge power. Engineers usually reply within one business day with sizing and a spec outline.
