Power generators

We offer VISA power generators: stationary, mobile, without enclosure or housed in enclosures or containers with sound proofing and resistant to weather conditions, with power ranging from 9 kVA to 2000 kVA. The power generators have diesel engines from Perkins, Deutz, Volvo, John Deere or Mitsubishi and alternators from Marelli or Stamford.
The power generators are equipped with fault-proof automatic systems which activate the generators in the event of power outage in the municipal (industrial) power supply network, as well as accessories enabling the generators to start in any weather conditions. The wide range of power generator accessory options includes remote panels of potential-free contacts, GSM control panels, software enabling control via the Ethernet, RS232, as well as the RS485 port in the Modus protocol.
The power generators have digital panels with large legible LCD displays in a range of options: for manual start-up, for automatic start-up compatible with an outside automatic transfer switching equipment (ATSE) system, for automatic start-up compatible with a dedicated automatic transfer switching equipment (ATSE) system, panels for power generator synchronization with the network and for synchronization of two power generators. Additional equipment options for the engine and the compressor increase the power generator’s stability, helping to maintain constant rotational speed regardless of increase in load (i.e. keep up the
frequency). AVR and AVR+PMG voltage regulators stabilize the power generator’s output voltage and are resistant to sudden load surges from 0 to 100 %.
Additionally, expanding the standard internal tank of the power generator is also possible. This way, without building costly external fuel installations, the generator’s operating time can be extended up to 24 hours (depending on the generator’s power rating). Obviously, even the expanded fuel tank has a limited volume, being an internal tank placed on the power generator’s frame.
We complete power generating systems, as well as any other additional installations required (ventilation, exhaust evacuation and fuel systems with extra fuel tanks).

VISA power generators have diesel engines from Perkins, Deutz, Volvo, John Deere or Mitsubishi and alternators from Marelli or Stamford, mounted on an anti-vibration frame. The power generators can be fully automated to enable a quick start and automatic switching of users in the event of failure in the industrial network. The power generator achieves its rate parameters within 5-15 seconds from the start. The generators can be used as emergency power supply and are compatible with uninterupted power supply (UPS). The generators can be supplied in soundproof enclosures. The noise level for power generators housed in sound-proof enclosures is 70-80 dB(A).

The power generators also come with:

  • Guard Evolution Manual control panel for starting the generator manually,
  • System for charging the start-up battery during downtime to ensure full readiness for engine start-up at any time,
  • Integrated internal fuel tank,
  • Industrial-type exhaust gas damper,
  • Start-up batteries,
  • Oil and coolant,
  • Electronic rotational speed regulator (depending on engine type).

Extra accessories:

Automatic transfer switching system. Dedicated system for network monitoring and automatic switching of load supply between the network and the power generator.
Residential-type exhaust gas damper. It reduces the noise level by ca. -30 dB(A) from the power generator’s own noise level.
Coolant heater. The device heats up the engine block to make sure it starts in any conditions. Supplied with singlephase alternating voltage, the heater has an automatic system built in the control panel.
Fuel system. The majority of power generators have an integrated internal fuel tank. Available are internal tanks of varying capacity featuring automatic or manual filling systems (option: fuel pump) and, if necessary, top/bottom level limit switches (option: 2-contact fuel sensors).
Water-tight and sound-proof containers. All power generator models can be provided with separate watertight and sound-proof container enclosures. They can be delivered in variants similar to standard containers. Moreover, models with extra sound proofing (up to ca.50 db(A)/1m) for special applications, e.g. in hospitals, residential districts, etc. are also possible.

Enclosure types:

C (Cover) – featuring light sound-proofing and resistant to weather conditions, reducing the noise level by approx.
-8 dB(A) from the power generator’s own noise emission level and conforming to applicable EU standards.
S (Silent) – sound-proofed and resistant to weather conditions, reducing the noise level by approx. -15 dB(A) from the power generator’s own noise emission level and conforming to applicable environmental protection standards.
SS (Super Silent) – extra sound-proofed and resistant to weather conditions, reducing the noise level by approx.
-20 dB(A) from the power generator’s own noise emission level and conforming to applicable environmental protection standards.

Guard Evolution control panel

Advanced microprocessor and digital control panels for power generators with manual or automatic start-up. The panels make it possible to monitor key power generator parameters such as: voltage, current, frequency, number of hours in operation, oil frequency, battery status etc.
