Fanless self-cooling
No fan, no moving parts, no intake. In dusty, hot and humid sites it does not clog or wear — zero noise, no maintenance.
Compact and high-output — 230 V single-phase or 400 V three-phase, your choice.
Industrial-grade portable power, without the diesel.
Build scalable, industrial-grade power — no fuel, no exhaust, no noise.
Fanless self-cooling, modular parallel, and a pure sine wave — built for the jobsite to replace the combustion generator.
It runs all of these
3,600 W rated and 20,000 W peak from a single unit, with three-phase output available. Every tool in this range is a compatible load — pick the model that fits the job.
- Work light100–600 W
- Impact drill720 W (1,800 W inrush)
- Angle grinder500–1,200 W
- Band saw800–1,500 W
- Demolition hammer1,000–3,000 W
- Cut-off saw1,200 W (2,400 W inrush)
- Chainsaw1,200–2,400 W
- Inverter welder160–200 A

NewSitePower P25
A 2.7 kWh unit built to run the site
- 2,500 W rated, 5,000 W surge, IP54 and 29 kg.
- Fanless self-cooling keeps it reliable in dust, heat and humidity.
- Parallel up to three units to scale the output — no engine, no fuel, no exhaust.
The engineering behind it
Four decisions make the range reliable where a diesel generator struggles.
Modular parallel
One unit, two units, or three in three-phase. The same platform scales from 2.4 kW to 10.8 kW / 400 V and can drive 160–200 A inverters and large power tools.
Compact, high power
P25 at 29 kg and P36 at 21–23 kg — leading energy density in a smaller footprint.
Power station vs diesel generator
The same job, two ways of doing it.
| Dimension | Hitama power station | Diesel generator |
|---|---|---|
| On-site emissions | No combustion, no exhaust. Usable indoors, in tunnels and underground. | Burns fuel and vents exhaust; the carbon-monoxide risk rules out enclosed spaces. |
| Noise | No moving parts — effectively silent on site. | An engine running all shift; hard to justify at night or beside housing. |
| Fuel | No fuel, no cans — charge it and go. | Fuel to buy, carry and top up, plus storage and transport to manage. |
| Maintenance | No engine oil, no filters, no carburettor. | Oil, air filters and spark plugs on a service schedule. |
| Dust | Fully sealed and self-cooled — there is no air vent to clog. | The intake filter traps the dust, and is cleaned or replaced on the service schedule. |
| Scaling | Parallel 2-3 units — power and capacity stack. | More power means buying a second, separate set. |
| Power quality | Pure sine wave, THD below 3%. | Voltage and frequency move with the load. |
| Running cost | No fuel bill and no engine servicing. | Fuel and servicing are a permanent line item. |

One more note: having no cooling vent to clog is also what separates us from air-cooled battery storage — dust, metal particles included, blocks their duct and takes the cooling capacity with it.

Run the numbers yourself
Two views of the same question: what a working day costs, and what a year costs. Both share your price assumptions — change one figure and both recalculate.

Diesel generator, per day8.56 €Fuel 7.12 € · Maintenance 1.44 €
Power station, per day2.05 €Grid electricity 11.9 kWh

A kilowatt-hour from the generator costs 0.82 € here, from the grid 0.20 € — a factor of 4.2.
- Generator, per kWh0.82 €
- Grid, per kWh0.20 €
- Factor4.2×
Both figures are per kilowatt-hour delivered to the load; charging losses are already included.
Is the capacity enough for a working day?
At 1.8 kW for 6 h the day needs 10.5 kWh. One P25 holds 2.7 kWh usable — the remaining 7.8 kWh comes from the grid, or you link 4 units for a day without a socket.
How we calculate it
Diesel: daily energy × consumption (l/kWh) × diesel price + maintenance per operating hour. Power station: daily energy divided by (1 − charging losses) × electricity price. The diesel price excludes CO₂ cost; that sits separately in the calculator below.
Adjust the assumptions
Estimate, not a commitment. Actual cost depends on load profile, machine, service interval and your tariff.

Let us get the diesel off the jobsite
One litre of diesel not burned is one less lungful of exhaust on site; one generator gone is one less fuel run and one less drum in the store. Cutting emissions is not a figure in a report — it is a choice made every morning. One machine, one crew, one site at a time: that is the part we would like to do with you.
