Industrial generator hire for demanding applications

Industrial power requirements can place very different demands on a generator from short-term or occasional use.

Factors such as load, operating hours, duty cycle and site conditions all need to be considered, particularly where temporary power will be supporting production or other essential processes for an extended period.

Industrial generator hire can provide a flexible source of temporary power for planned and unexpected requirements, from scheduled shutdowns and factory moves to additional capacity and delays to permanent grid connections.

Planned shutdowns

Maintain power to essential equipment and processes during planned maintenance, electrical works or infrastructure upgrades, helping you minimise disruption while work takes place.

Process continuity

Provide temporary power when an existing supply is unavailable or additional capacity is needed, helping keep production lines, machinery and other essential industrial processes operating.

Grid connection delays

Keep projects and operations moving when you're waiting for a new or upgraded grid connection, with temporary generation providing the power you need in the interim.

Temporary factory power

Support factory moves, phased fit-outs, site expansions and periods of load growth with temporary power tailored to the changing requirements of your operation.

Prime vs standby vs continuous generator ratings

Generator size isn’t the only consideration when arranging temporary power. The generator’s power rating also needs to suit how it will be used, including how long it will operate and whether the electrical load remains relatively constant or varies over time.

Understanding the difference between prime, standby and continuous ratings is particularly important for industrial applications where a generator may be required to operate regularly or for extended periods.

Prime power

Prime-rated generators are designed to operate for an unlimited number of hours with a variable electrical load, subject to the manufacturer's operating and maintenance requirements. This makes prime power suitable for applications where a generator is used regularly or as the main source of power.

Standby power

Standby-rated generators are designed to provide temporary backup power, typically when the normal mains supply fails. Their permitted operating hours and loading conditions are more restricted, making the rating unsuitable for applications requiring regular or prolonged generator use.

Continuous power

Continuous-rated generators are designed to provide power continuously at a constant load for an unlimited number of hours, subject to the manufacturer's operating and maintenance requirements. This differs from prime power, which is intended to accommodate a variable electrical load.

Why the generator rating matters on a long-term hire

Using a generator outside the conditions associated with its rating can affect performance, reliability and equipment life. A generator intended for occasional standby use, for example, shouldn’t simply be treated as a regular source of power for an extended hire.

That’s why both generator size and power rating need to be considered when specifying temporary industrial power.

Our solutions team can assess the expected load and operating pattern to determine the appropriate generator for your application. Contact us for tailored advice.

Everything you need for temporary industrial power

A generator is only one part of a working temporary power setup. From getting power where it’s needed to keeping the generator fuelled, the supporting equipment needs to work together from day one.

Rehlko can provide the generator, cabling, distribution and fuel equipment as a coordinated hire package, removing the need to juggle multiple suppliers and separate equipment orders.

Distribution

Get temporary power safely to the equipment and areas that need it, with distribution boards specified to suit your generator and site setup.

Cabling

We'll factor the cables, connections and routes needed to get power from the generator to your equipment into the temporary power setup from the outset.

Fuel management

Keep your temporary power up and running with fuel tanks and associated equipment matched to the generator, expected usage and length of hire.

Monitoring and support

Rehlko's remote telemetry monitors key aspects of your hire generator's operation, helping keep essential or backup power running smoothly without regular engineer visits to site.

Remote monitoring

Site setup

Generator positioning, cable routes and day-to-day site activity are all factored into your setup, with traffic management solutions available where required.

Cleaner, quieter temporary power options

Industrial sites can have specific emissions and noise requirements, particularly where generators will operate for extended periods or close to employees, neighbouring businesses or other occupied areas.

Rehlko offers a dedicated Stage V generator hire range for lower-emission temporary power, alongside silent generators designed with sound-absorbing technology to reduce operating noise.

Hydrotreated Vegetable Oil (HVO) is also stocked for use across the hire fleet, providing a lower-carbon alternative to conventional diesel.

Our solutions team can help you consider emissions, fuel and noise requirements alongside your load and operating needs when selecting the right generator for your site.

Industrial generator hire across manufacturing and utilities

Rehlko works across manufacturing and utilities, providing generator hire to meet the operational demands of each environment.

Manufacturing

Keep production and essential processes running during planned shutdowns, factory moves, phased fit-outs or interruptions to the mains supply. Temporary generator hire can also provide additional capacity while you wait for a new or upgraded grid connection.

Hire or buy an industrial generator?

Generator hire can be a practical choice when you need temporary power for a planned shutdown, factory move, short-to-medium-term increase in capacity or while waiting for a permanent power supply. It gives you access to the power you need without investing in equipment you may only require for a limited period.

If your power requirement is permanent or long term, purchasing an industrial generator may be more appropriate. Rehlko can help you assess your requirements and determine whether hiring or buying is the right option for your site.
