Our Solutions

Geothermal Power Generation Solutions
United Energy's Geothermal-to-electricity systems using advanced ORC technology (including steam + ORC combined cycle and standalone ORC for 90–160°C sources).
The EXERGY turbine achieves isentropic efficiencies of up to 93.65%, and solutions are active in Turkey, Japan, and Portugal.

LNG Cold Energy Utilisation
United Energy's LNG cold energy reuse, which involves recovering cold energy from LNG regasification for:
-
Cold storage and logistics
-
Freeze-drying (food/pharmaceuticals)
-
CO₂ liquefaction and dry ice production
-
District cooling for hotels, data centers, and indoor snow parks

ORC Systems
United Energy's Organic Rankine Cycle (ORC) solutions for converting industrial low- to medium-temperature waste heat into electricity. These systems are modular, efficient, and tailored to various industries

Chemical Process Maintenance and Recovery
(CPMR System)
A CPMR descaling system is an industrial cleaning solution designed to remove mineral scale, rust, and other deposits from internal surfaces of process equipment.
CPMR systems restore thermal efficiency, reduce energy consumption, and extend equipment lifespan, all without the need for disassembly.
