Packaging of the equipment is conducted at owned production facilities (Kolomna, Moscow Region).

Gas power plant

Gas reciprocating power plants ROLT PSG produce power and heat from gas by reciprocating generating unit. It is installed on the frame with gas reciprocating engine and an alternator. If the unit is combined with the heat recovery system, it can also produce heat.  
We take care of the reputation of our company and carefully choose producers of gas reciprocating units for our goods. After operational experience and cost-effective analysis we have chosen the following companies:
  • Caterpillar Inc. (USA)   
  • Jenbacher Gas Engine (Austria, the company is a part of American multinational corporation GE).
  • MWM (Germany, till 2008 the company worked under Deutz brand).

Diesel power station

Diesel power plants ROLT PSD can be used for primary or standby electrical supply (less often heat supply) produced from diesel fuel. We manufacture different types of diesel power plant: on frame, in container, mobile – on low frame platform. 

All power plants ROLT PSD can be equipped with heat recovery system. Among their characteristics we can name high productivity and long service life. The specialists of our company can also render maintenance and repair services for the equipment of the power modules. Our equipment corresponds to Russian norms and regulations. 

ROLT PSD is produced on the base of generators:
  • Caterpillar Inc;
  • Cummins;
  • MTU;
  • FG Wilson.

Cogeneration of heating and power

The heat produced by gas or diesel power plant can be used for production of hot water, steam or cold (triegeneration) for technological processes which require a lot of heat energy. Heat recovery system or CHP allows getting maximum profit and considerably reduces the payback period. The advantages of heat recovery system developed by ROLT power systems for gas or diesel power plants in comparison with the main cycle are evident: increase of fuel effectiveness up to 90%, high economic performance, self-containment, minimal level of heat loss because of the short distance between power plant and the consumer, etc. Mini CHP can be integrated in any technological process maximizing fuel efficiency and reducing costs.

Automatic Process Control System

We use our own control system for operating control and monitoring of power plant ROLT PS and its engineering systems. The monitoring system allows you to analyze a lot of digital and analog signals of controlling parameters of the equipment from different manufactures and having different communication protocols (gas reciprocating power plant, diesel power plant, packaged switchgear, low-voltage package module, etc). The operation and control parameters of power center can be controlled on the display of the personal computer of the operator of a personal automated station. Operator signals about emergencies by visual row and by alarm. View »

Package transformer substation

Package transformer stations (PTS) receive, convert and distribute electricity produced by the power plant.  PTS convert AC of 0,4 kV into high voltage electricity of 6,3 or 10,5 kV and vice versa. Safe and reliable work of transformer station is provided with switchgears and relay protection. The main components of PTS are high-voltage switchgear and low-voltage switchgear.

PTS of container type manufactured by ROLT group in Kolomna have many advantages:
  • Configuration of the module guarantee its high mobility,
  • It can be transported by truck, rail or water,
  • A station can work at the outside temperature from -60 to +40 °C under snow or wind load.
