Assembly and supply
OTS assembles and supplies generators. We also trade generators from other brands. Tell us your loads, how the generator will be used and where it will run, and the quotation confirms the right generator.
Not sure what size you need?
Choose the sizing option in the quote form and tell us about your loads. We will recommend the size in our quotation.
The form asks for:
- The main equipment to power, with quantities and power in kW if known
- The largest motor and how it starts
- Whether all loads run at the same time

Installation, maintenance and spare parts
Alongside assembly and supply, we install generators, service them and supply spare parts.
Installation
We install generators on site: connection to the electrical system through a changeover or transfer switch, start-up tests, and handover with basic operating guidance. The scope is confirmed in each quotation.
Good practice on site
- A ventilated location, away from windows, because of exhaust gases
- Correct earthing
- Protection against back-feed into the grid
Give the site's country and city in your request.
Maintenance
Scheduled servicing based on running hours and the manufacturer's recommendations: oil, filters, inspections and tests. When faults appear, we diagnose and repair them.
Signs that a generator needs attention
- Black smoke
- Hard starting
- Unusual noise or vibration
- Unstable voltage or frequency
- Alarms
Spare parts
We supply generator spare parts. Send us the generator's make, model and serial number, or the part number, and we will confirm availability and price in our quotation.
A photo of the part or the nameplate helps us identify it.
