Open, Silent, Mobile or Containerised: Choosing the Build Form

Open frames are cheapest and need a shelter. Silent canopies cut noise for towns and occupied sites. Mobile sets move with the job. Containerised builds pack power, fuel and control into one weatherproof box for remote duty.
The build form decides where the set can sit, how loud it is, and whether it moves. Open frames are the lowest cost and need a shelter. Silent canopies cut noise for towns and sites near people. Mobile sets travel with the work, and containerised builds put power, fuel and controls in one weatherproof box for remote duty. Choose the form from the site, not the price list.
The four build forms at a glance
Each form trades cost and weather protection against noise and mobility. The table sets out the defaults; the sections below explain when each one is the right call, and the noise figure note covers what the dB(A) rating actually means.
| Build form | Noise | Weather | Moves? | Best for |
|---|---|---|---|---|
| Open frame | Loud, no enclosure | Needs a shelter | No | Plant rooms, compounds |
| Silent canopy | Low, enclosed | Weather resistant | No | Towns, sites near people |
| Mobile or trailer | Medium | On a road trailer | Yes | Construction, events, rental |
| Containerised | Low to medium | Fully enclosed | By truck or ship | Mines, remote, 24/7 duty |
Open frame
An open set is the engine, alternator and base with no acoustic enclosure. It is the cheapest build and the easiest to service, but it is loud and exposed, so it needs a plant room or a walled compound away from people. It is the natural base for the other three forms.
Silent canopy
A silent canopy wraps the set in an enclosure with intake and exhaust silencers and absorbs the noise. It is the default for any site near homes, offices or hospitals, and the dB(A) note explains how to read the rating against distance. KINBOOST builds silent canopies across the 20 to 2000 kW range.
Mobile and trailer mounted
A mobile set mounts the engine, alternator, fuel and controller on a road trailer with braking and lighting, so it moves with the job. It suits construction, events and rental fleets where the power point changes weekly. The construction sizing guide and the rental fleet note cover the duty these see.
Containerised
A containerised set packs the engine, alternator, fuel tank, control and sometimes a walk-in service space into a shipping container shell. It is weatherproof, stackable for shipping, and built for mines, remote camps and 24/7 duty where no plant room exists. The mining sizing guide shows the conditions that push buyers to this form.
How to choose
Start from the site: indoor or outdoor, near people or remote, fixed or moving. Then match the form, and only then compare price. The decision table below turns the site into a form.
| If the site is... | Choose |
|---|---|
| Indoor plant room, no neighbours | Open frame |
| Near homes, offices or a hospital | Silent canopy |
| Changing location each week | Mobile or trailer |
| Remote, no building, 24/7 | Containerised |
Frequently asked questions
Can an open set be used outside?
Only inside a shelter or a walled compound away from people, because it is loud and exposed to weather. For an outdoor site near anyone, a silent canopy is the safer default.
Is a silent canopy weatherproof?
It is weather resistant for outdoor siting, with enclosed panels and protected intakes, but it is not a sealed shipping container. For fully enclosed remote duty, the containerised form is the right call.
Do mobile sets need a special trailer?
Yes, a road trailer with braking, lighting and a skid base so the set can be towed and set down without a crane. The construction guide covers the duty.
Why choose containerised over a canopy?
Because it is a weatherproof, shippable box with fuel and controls inside, built for sites with no building and continuous duty, such as mines and remote camps.
Does KINBOOST build all four forms?
Yes, across the 20 to 2000 kW range in diesel and gas or dual-fuel, with Perkins, Cummins, Yuchai, Shangchai, Weichai and Changchai engine options. The diesel sets page shows the range.
