Design and supply of turnkey trigeneration plants

On-site generation of electricity, heat and cooling for industry and commercial real estate.

Trigeneration and its main advantages

A trigeneration plant produces cooling in summer and heat in winter, which makes it attractive from an economic point of view.

More about trigeneration
Fuel utilization80–85%

instead of 35–40% for a gas engine without heat recovery.

Absorption chiller service life20–25 years

according to the manufacturer's catalog.

Thermax machines worldwide5,000+

in operation at factories, airports, data centers and shopping malls.

Our projects15+

trigeneration projects in Russia and the CIS, and many other cooling projects.

What the site gets

One gas-fired plant covers three cost items. The grid stays as a backup, and the boiler house covers peak heat.

Electricity

Your own power all year round, plus capacity the grid cannot provide or sells at a high price.

Heat

In winter, engine heat warms buildings, hot water and processes instead of the boiler house.

Cooling

In summer, the same heat goes into an absorption chiller and becomes chilled water at 7/12 °C.

Gas goes into a gas engine. It produces electricity and heat. The heat goes to space heating and into a Thermax absorption chiller, which makes cooling; an NCT cooling tower rejects the chiller's heat.

Cold Energy: Thermax, NCT and gas engines in one company

We design, supply, supervise installation, commission and service the cooling circuit. Our company is the only supplier of Thermax machines in Russia and the CIS, and you can order the engine and the cooling together.

About us
The main risk

Trigeneration fails at the interfaces, not in the engine

The engine depends on the chiller: if the chiller stops, the heat has nowhere to go. The chiller depends on the engine: if the load drops, there is no cooling. International reviews name the same main causes of failure: the plant was sized on electricity rather than heat, and it runs too few hours. We look at the six interfaces where money is lost.

Six mistakes explained

The six places where mistakes are made most often: exhaust back pressure, engine jacket overheating when the chiller stops, return temperature, engine loading and cooling demand out of step, crystallization on power failure, untreated cooling tower water. All of them sit at the interface between generation and the cooling circuit.
Who does it

Gas engines, the cooling circuit and the interface between them under one contract

  • Cold Energy is the only supplier of Thermax machines in Russia and the CIS. Factory selection, supply, installation supervision, commissioning and service of the machines go through us.
  • Gas engines. We supply the engine together with the cooling, so heat and operating schedule are calculated for both machines at once.
  • NCT equipment. Cooling towers, chillers, dry coolers, pump skids, water treatment and controls designed for one scheme.
  • Experience on real sites. Around 15 trigeneration projects: greenhouses, factories, shopping malls, turbines and many others.
  • An honest calculation. The feasibility study is free. If your site does not need trigeneration, we will say so and calculate a different scheme.

Frequently asked questions

Will trigeneration pay back if the site has enough electrical capacity for now?

It may not: the benefit comes from replacing grid kilowatt-hours and avoiding the fee for new capacity. If the connected capacity will not be enough in the future and you need the power anyway, the calculation changes. That is why we calculate both cases.

How does payback change if surplus electricity cannot be sold to the grid?

The plant is sized for your own consumption. If your own load is small and there is no large cooling demand, the project is not justified: one of our customers turned it down for exactly this reason.

Can we see your equipment on an operating site and talk to the operators?

Yes. We will show a reference list of similar projects, arrange a site visit and, on request, give you customer contacts for a phone conversation.
