The Opportunity
From pressure letdown stations to exhaust gas streams, enormous amounts of recoverable energy are dissipated every day — waiting for the right technology to capture them.

Micro turbines & expander-generatorsThe Turbochill Approach
Turbochill develops the high-speed rotating machinery at the heart of compact power generation systems — engineered for applications where conventional turbines are too large, too slow, or simply uneconomical.
Our oil-free turbocompressor and turboexpander platforms serve as the technological foundation for two key families of power generation equipment: micro gas turbines for distributed electricity and heat production, and expander-generators that convert otherwise wasted pressure and thermal energy into useful electrical output.
Built on gas and active magnetic bearings, these machines operate without lubricants, without gearboxes, and with minimal maintenance — delivering the reliability and energy density that modern decentralized power systems demand.
Micro Gas Turbines
High-speed, oil-free turbomachinery designed for distributed generation and combined heat & power — from remote installations to on-site industrial CHP.
Single-shaft architecture with permanent magnet generator and centrifugal compressor — all spinning on oil-free bearings at speeds exceeding 100,000 rpm.
Designed to run on natural gas, biogas, hydrogen blends, or liquid fuels — adapting to whatever energy source is available on-site.
Exhaust heat recovery pushes total system efficiency beyond 85% — making micro turbines ideal for facilities that need both electricity and process heat.
Expander-Generators
Wherever gas or steam is throttled, expanded, or vented, there is a pressure drop — and with it, an opportunity to generate electricity instead of dissipating energy into nothing.
Turbochill's expander-generator technology replaces conventional pressure reduction valves with high-speed turboexpanders coupled to integrated generators — capturing energy that would otherwise be entirely wasted.
Gas is routinely throttled from transmission to distribution pressure. Our expander-generators turn that pressure drop into clean electricity — at every metering and regulation station in the network.
Industrial plants frequently reduce steam pressure between process stages. Instead of wasting that enthalpy through throttling valves, an expander-generator extracts useful work from the expansion.
Chemical plants, refineries, and LNG facilities all handle high-pressure gas streams. Wherever that pressure is reduced, an expander-generator can be integrated to recover power continuously.
The Bottom Line
Across natural gas networks, industrial steam systems, and process plants, enormous amounts of energy are routinely destroyed in pressure reduction. Turbochill's expander-generator platform turns these losses into a revenue stream — with no fuel, no combustion, and near-zero operating cost.
Key Advantages
Our high-speed rotating equipment gives system integrators and OEMs a technological edge that conventional machinery cannot match.
Gas and magnetic bearing systems eliminate lubricant circuits, oil changes, and the contamination risks that come with them — dramatically cutting lifecycle costs.
High rotational speeds and optimized aerodynamics deliver large power output from a remarkably small footprint — ideal for retrofits and space-constrained sites.
Permanent magnet motor-generators with power electronics allow precise speed and load matching — maintaining peak efficiency across varying operating conditions.
The same core rotating assembly can be configured as a compressor, expander, or generator — allowing system builders to address multiple markets from one technology base.
