About Cold Energy (NCT): trigeneration, Thermax absorption chillers and NCT equipment

Since 2011, Cold Energy (NCT) has designed, supplied and serviced cooling systems for industry and commercial real estate, including systems for trigeneration (CCHP). We are the official representative of Thermax in Russia and the CIS (absorption chillers) and the manufacturer of NCT cooling towers and chillers; NCT dry coolers are also in our range. In Russia and the CIS, Thermax machines are supplied only by Cold Energy. We also supply gas engine generator sets. For the cooling circuit, the company covers design, supply, installation supervision, commissioning and service.

See the descriptions in the Projects section, customer letters in the reviews section, and Thermax projects worldwide in the world projects section.

Where did we come from?

We started by supplying absorption chillers. It turned out that the customer needs a working system, and the machine is only one part of it. So the company set up a design department, and then production of NCT equipment, control cabinets, pump skids and water treatment systems. More about the equipment: trigeneration plant and the nc-t.ru website.

Why should one company handle the interface between generation and cooling?

Because trigeneration most often fails between the engine and the absorption chiller. Six places where mistakes happen: exhaust back pressure, engine jacket overheating when the machine stops, return temperature, engine load and cooling demand out of step, crystallization on power loss, and cooling tower water without treatment.

At each interface the engine and the cooling side meet. If they are split between different contractors, the interface belongs to no one: each answers for their own part and can blame the other. A UK review of gas cogeneration (CHP) names, among the reasons for failure, in-house teams underestimating the complexity of a gas plant and savings on procurement that led to low reliability. With us, you can order the gas engine, the cooling circuit and the interface between them from one company:

Engine: gas engine generator sets.
The entire cooling circuit: Thermax absorption chillers, NCT cooling towers, dry coolers and chillers, pump skids, water treatment and controls.
The interface between them: exhaust and jacket water data from the engine datasheet at 100, 75 and 50% load, back pressure, damper, bypass.
Design, installation supervision, commissioning and service of the cooling circuit by one contractor, so in case of a failure nobody argues about whose area it is.

A breakdown of the six interfaces: why trigeneration does not pay off. If the scheme does not suit you, we will say so: below 2,000 hours a year and under 300 kW of cooling, an absorption chiller does not pay off.
