An industrial generator may remain on standby for weeks before being called upon to power a building’s essential loads during an outage. At that moment, its availability depends both on the equipment’s design and on how it has been installed, inspected and maintained.
The new Rehlko KD Series 60–600 kW range focuses on value throughout its service life, supported by access to genuine parts and the manufacturer’s service network. For owners and operators, this brings several factors into consideration from the purchasing stage: maintenance, operating costs and the technical support available after commissioning.
Plan Maintenance from the Start
Low operating hours do not eliminate the need for maintenance. For a standby generator, extended periods of inactivity are part of normal operation, and the equipment must remain ready to start.
The maintenance schedule should follow the specific model’s documentation, taking operating hours, calendar intervals and site conditions into account. Checking fluids, filters, the starting battery and the cooling system is part of this preventive approach.
For a KD Series generator, planning maintenance from commissioning onwards helps organise service visits and identify potential issues early. Keeping a service history also provides a clear record of the equipment’s condition and the work carried out.
Assess Fuel Consumption Under Real Operating Conditions
Fuel consumption is meaningful when considered alongside the load being supplied and the operating duration. A figure expressed in litres per hour, without specifying the generator’s load level, gives an incomplete picture of running costs.
Selecting a KD Series model should therefore start with the actual electrical loads, their starting currents and how they will operate simultaneously. An appropriate power reserve is useful, but excessive oversizing can result in prolonged operation at very low loads.
The operating budget also includes scheduled maintenance, consumables, periodic inspections and any repairs. Considering these costs together provides a more realistic assessment of the investment over its service life.
Include Parts and Consumables in Your Operating Plan
Access to the right parts matters for both scheduled maintenance and corrective work. Rehlko identifies genuine parts availability and local support as key elements in the long-term operation of the KD Series range.
In practice, components should be identified using the equipment’s model, serial number and configuration. This helps ensure that the correct consumables and replacement parts are selected in accordance with the manufacturer’s documentation.
Planning parts requirements ahead of a service visit helps maintenance work run efficiently. For critical applications, the need to keep consumables or spare parts on site can be assessed with the service team, taking the installation’s importance and procurement lead times into account.
Check the Entire Backup Power System
Engine starting is only one of the functions that needs to be checked. Backup power availability also depends on the control system, automatic transfer switch, starting battery, fuel supply and ventilation.
Periodic testing, including load tests specified for the installation, helps assess the system’s performance. These tests should be planned by qualified personnel, with due consideration for the facility’s operations.
For owners and operators, documented results and technical recommendations are just as important as the checks themselves. They make it possible to track issues and schedule the necessary corrective actions.
Technical Support Throughout the Equipment’s Service Life
In Romania, Best Tools Company supports Rehlko generator operation through commissioning, training, maintenance, repairs and spare parts supply, with nationwide coverage.
A maintenance agreement can clearly define scheduled work, responsibilities and service response terms. This helps owners and operators plan their budgets and maintenance activities more effectively.
For a Rehlko KD Series generator, long-term performance is supported by correct configuration, consistent maintenance and access to specialists who understand both the equipment and its application.
