For the structure of transportable power stations see the following chart. A “transportable power station” (PEC) consists of individual modules with heat sources that can, upon request, be complemented with modules for electricity generation or with modules with absorber cooling units in a wide output range. According to the form of the thermal output of PEC, the stations are split into “Transportable steam power stations” (PECP) and “Transportable hot water power stations” (PECT).
Transportable steam power stations – PECP
The core of this plant is a containerised steam boiler room (KK), supplying heat in the form of saturated or super-heated steam. The “steam turbo-generator module” (MPTG), fitted with a steam turbo-generator and a complex protective and control system, serves for the generation of electricity and its supplies into the distribution network and/or for the boiler room or production technology needs. In the case that cooling output supplies for technological purposes are needed, a containerised boiler room (KK) can be supplemented with an “absorber cooler module” (MC) using waste heat from the PEC module to produce the necessary cooling capacity. Another module which can be added to the power plant is a “module with a co-generating unit” (MKJ) formed by a gas engine or a diesel generator set, allowing for combined generation of electricity to be supplied into the distribution network and/or used to power the power plant itself (the so called “island” operation). The above mentioned modules may be tailored to fit specific requirements.
Transportable hot water power stations – PECT
This module is based on a PV or KK containerised hot water boiler room with heat transfer fluid in the form of hot (up to 110°C) or superheated water (over 110°C). The PECT station may be supplemented with the same modules as transportable steam power stations, except for the MPTG module with a steam turbo-generator.
Individual modules are designed in a wide output range, which allows us to tailor PECs according to the client’s requirements for the power source capacity, the output heat transfer fluid and the electrical or cooling output required. The entire PEC is supplied in a short time, at minimised assembly costs. These modules may be supplemented with steam or hot water storage reservoirs, which are also part of the PolyComp Energo s.r.o. delivery programme. By combining these modules a transportable power station (PEC) may be devised with practically unlimited thermal, electric and cooling functions.
The main advantages of transportable power stations (PEC) of this design are:
- almost unlimited thermal, electric and cooling capacity applying the heat transfer fluid required
- “island” operation of the entire transportable power station
- full-value transportable energy source
- rapid delivery times for the client
- minimum requirements for construction space and its development
- minimum installation requirements and costs
- possibility of dismantling and transfer to another location
These units serve for thermal energy generation in the form of saturated or superheated steam or electric energy, or they provide the cooling capacity required. PECPs have practically unlimited thermal and electric outputs, obtained by combining individual containerised steam boiler rooms, supplied within the output range from 100 kg/hrto 30 t/h. In PECP, electric power is generated by modules with high-speed steam turbo-generators (MPTG) installed next to the steam boiler room, with an output range from 20 kW to 3 MW, or MKJ modules with co-generating units based on gas engines or diesel generator sets with electric outputs from 20 kW to 1 MW. For potential cooling function MC modules with absorber coolers are available using the PEC waste heat. PECP stations may be supplemented with steam storage reservoirs of AT type.
Some examples of PECP modulation and configuration:

These units serve for thermal energy generation in the form of hot water, electric energy or cooling energy. PECTs have practically unlimited thermal and electric outputs, obtained by combining individual hot water boiler rooms with outputs from 60 kW to 20 MW. The electric energy generation to be supplied into the distribution network or for PECT service consumption is provided by additional MKJ modules with co-generating units based on gas engines or diesel generator sets, with electric outputs of 20 kW – 1 MW. By connecting a MC module with an absorber cooler with a capacity from 300 to 1300 kW the cooling performance required is covered by using the station’s waste heat. PECTs may be supplemented with storage reservoirs, which makes the operation of MKJ modules with co-generating units based on gas engine or diesel generator sets more effective.
