Power for demanding technological operations
Generators for asphalt plants
A generator for asphalt plants provides reliable power for the technological operation in demanding conditions. We design a suitable solution based on the output, technology type, duty regime and the specific requirements for operational certainty.
- Indicative range 200–750 kVA
- Hundreds of kVA operating output
- Standby and operating duty
Overview
Why power reliability matters for asphalt plants
Output, technology type, duty regime and location differ. A correctly designed power supply must match the specific operation — not a generic catalogue solution.
A smaller mobile asphalt plant has different requirements than a large stationary operation. A precise design of output and configuration always arises from the specific operation and conditions of deployment.
The indicative range of 200–750 kVA applies to typical operations. A large stationary plant with multiple drums or special equipment may require different sizing.
Risk of an outage
What an outage causes in an asphalt plant
Lost production time
Every interruption of the technological operation means irretrievably lost production time — especially in seasonal peaks when capacity is fully utilised.
Damaged batch
An outage during aggregate heating or mix preparation can damage the batch, block conveyors or cause material to set in the system.
Limited connection
Asphalt plants stand in industrial zones or outside built-up areas where connection capacity is limited or sufficient grid draw cannot easily be secured.
Contract penalties
Asphalt mix deliveries are tied to construction schedules. Delayed production caused by a power outage is directly reflected in costs and contractual penalties.
Long restarts
Restarting the plant after an unplanned outage requires time, staff and a check of the technology's condition. Every restart extends the total downtime.
Operational risk
A failure of control systems and ventilation in an operation with hot surfaces and combustion processes can pose a direct operational risk.
Where it fits
When a generator for an asphalt plant is a suitable solution
Insufficient grid capacity
An operation where the distribution grid cannot cover the full output of the technology or where connection capacity is unstable — the generator provides the required output without limitation.
Automatic backup
A generator with ATS automatically transfers power to key technologies during an outage — without manual intervention and with minimal interruption of operation.
Mobile and seasonal plants
Mobile asphalt plants or seasonal operations where no permanent connection is available or where the production site changes according to construction contracts.
High-output technology
Drying drums, burners, compressors, conveyors and control systems — the operating output of an asphalt plant is usually in the order of hundreds of kVA and requires dimensioned power supply.
Certainty-critical production
Where an interruption of production means a lost batch, damaged material or the need for a lengthy restart — and where operational certainty is key.
Comparison
Standby power or operating source — it depends on the specific deployment
Standby and operating use differ in sizing, ATS configuration, tank size and service requirements. A correct design starts with a clear answer to how the generator should work in your operation.
Generator as a standby source
- Automatic takeover of key technologies during a grid failure — without manual intervention.
- Key parameter: reliability and speed of transfer.
- Sized for the critical circuits of the plant, not necessarily the full output.
Generator as an operating power source
- Primary or supplementary source where the connection is insufficient or unavailable.
- Key parameter: output, autonomy and fuel capacity.
- Different sizing and shorter service intervals.
Design factors
What must be considered in the design
Output with peaks
Total consumption of the technology including starting peaks of the largest motors — dryers, burners, compressors and conveyors.
Technology subsystems
Drying drums, burners, dosing, conveyors, dedusting and the control system — every subsystem contributes to the total consumption and has its own starting characteristics.
Duty regime
Standby and operating use differ in sizing, ATS configuration, tank size and service requirements. The design starts with how the generator should work in your operation.
Fuel autonomy
The required length of operation determines the tank size — from covering peak loads to multi-day operating duty.
Location and emissions
Placement of the unit, exhaust routing and possible emission requirements (Stage V where applicable) according to the conditions of deployment and local regulations.
Service
Access to service support, spare-parts availability and contracted service corresponding to the duty regime and the seasonality of the operation.
System solution
Not just a generator, but a complete functional system
Industrial generator units
Industrial AKSA generators with Perkins, Doosan or Volvo Penta engines. Outputs matched to the requirements of the specific plant — usually in the range of 200–750 kVA.
ATS and switching
For standby duty the transfer switch provides automatic changeover during an outage without manual intervention — with minimal interruption of operation.
Switchboards and connections
Power and control interconnections, coordination with the plant's main switchboard and the existing installation.
Fuel storage
Integrated or separate tank sized for the required autonomy, including a drip tray and a refuelling connection.
Execution
Canopied or container execution for installations with noise requirements; open execution for machine rooms.
Commissioning and service
Energisation, load tests, documentation handover and service setup adapted to the duty regime and the seasonality of the operation.
