Gas generators and cogeneration

Caterpillar is one of the leading companies in the world, which offers efficient and reliable electric power generating solutions, while maximizing customers' return on investment. 

Cat gas gensets are the industry benchmark for reliability and performance. They are manufactured in Caterpillar factories according to ISO 9011 quality standards. Innovative technologies as well as company's vast experience guarantee exceptional quality, reliability and notedly lower maintenance costs.

A full range of Cat gas generator sets, available to utilize natural gas fuel as well as low energy gases, is presented below.


In today’s environment of high gaseous fuel prices, gas engine based Combined Heat and Power installations also called Cogeneration or CHP represent an attractive solution to investors to provide reliable heat and power to their industry or production while maximizing their return on investment.

Combined Heat & Power (CHP or Cogeneration) – is one of the most popular energy-saving technologies. It is the simultaneous and sequential use of power and heat from the same fuel source. When generating electricity, a large amount of heat is produced as a by-product. In traditional power generation methods this is wasted, but a CHP system recycles this heat. In other words, heat recovered from generation is used for heating or cooling, typically with an absorption chiller. This reduces the transmission and distribution losses that occur when fuel is burned, increasing the efficiency of the system. Use of heat for both heating and cooling is known as Tri-generation.

 CHP schemes are mainly used by the industrial, commercial and some public sectors – mainly those needing a great deal of heat such as hospitals, universities, leisure centers, offices and retailers. Those industries can be divided in three categories:

  1. The ones with intensive electric applications: hospitals, offices, shopping malls, industrial processes, logistic centers, etc. Here, the primary purpose for installation is electric power. CHP operates when electricity is required and utilizes load balancing radiators - exhaust circuit bypass.
  2. The ones with requiring heat and power equally: cement plants, chemical processes, food processing. In this case, both heat and electric power have equal value. Here, CHP are much more complex systems, which require radiators and thermal accumulators.
  3. And the ones with intensive heat applications: greenhouses, district heating, central steam plants. These applications' primary purpose for installation is heat-related. Such system operates when heat is required and utilizes thermal accumulators-direct connection, which can be hot water or steam circuits.
