with higher efficiency, unique adaptability and a smaller footprint - meeting your sustainability needs. A unique construction worldwide making the engine a robust and variable power generator.

Our innovative approach rethinks every stage of the engine life cycle to improve efficiency and reliability. The revolutionary design simplifies use and maintenance, directly improving productivity and efficiency.

HITRPM steam engine -

Optimal output yield at full and partial load due to innovative design
Constant efficiency rate over a wide operating range
Moderate feed water treatment requirements
Short delivery times due to modular design
Durable and robust
Simple to operate
•Maintenance can be performed by own staff
Deployed in CHP units, the HITRPM steam engine ensures a high electricity production due to its optimum efficiency in full and partial load ranges while being tolerant of fluctuating steam conditions

The difference and advantage of this design:

This engine combines the advantages of an internal combustion engine, which allows it to translate the reciprocating motion of the

of the pistons into the rotational motion of the rotor;

The cylinders are cross-shaped borings in the rotor, which, in turn, is driven into

rotation in the housing of the HITRPM through a special mechanism;

The design allows the use of low-pressure steam (from 2-3 kg/cm 2 ) and 75% efficiency utilization of steam heat energy;

Low working pressure required for the operation of the HITRPM does not require a special permit.

Main characteristics:

At a low steam pressure of 2 kg/cm 2 we get 600 kW of electricity from the generator;
At a steam pressure of 6-10 kg/cm 2 - 2-3 mW;
The volume of the afterburner is 25 liters.

With a high torque, the 223 rpm engine shaft onboard the onboard air converter is sufficient to maintain 500 rpm at the generator after a step-up reduction.

This engine combines all the best qualities of the various engines and eliminates their disadvantages. The windows are as in a 2-stroke engine, but the cylinders are one-piece, as in a 4-stroke engine, but without the complex system of valves and camshafts. Rotor rotation like a turbine, but the steam does not pass through a system of complex blades, but pressurizes the pistons in closed cylinders. And more, this steam engine operates at low pressure from 3 kg/cm2 and above with steam temperature from 130 to 200 degrees Celsius and at low speeds from 250 to 750 per minute, while the steam coipensational turbine operates at steam pressure of 35-45 kg/cm2 and above and the temperature of superheated steam 450 degrees Celsius and above,
and at 1,500 to 3,000 rpm.
The efficiency of this engine, according to calculations. should be at least 60%
There are also low-power turbines at low pressure, but they are also inferior to this engine in all parameters.

HITRPM steam engine:

the only one of its kind in the world.

The advantages of HITRPM steam engine are particularly significant in heat-driven back-pressure cycles or with varying steam flows. That makes it ideal for use in plants with smaller to medium outputs, e. g. in

Geothermal power generation
Combined heat power plants (CHP)
Smaller plants that produce electricity from biomass from approx. 3 MW fuel input
Waste heat generation units from approx. 2.5 t/h steam mass flow
Waste incineration plants and thermal afterburning units

The HITRPM steam engine is also optimal in combination with saturated steam boilers, as well as steam generators with moderate live steam pressures and temperatures.

HITRPM steam engines can also be adapted optimally to various steam pressure differences can be handled using only a single expansion engine.

This realises the operation over a wide range almost without pressure losses and so guarantees constant efficiency to large extent.
