District heating & cooling

The heat and refrigeration networks are systems that generate thermal energy (heat and cooling) in a centralized production plant and distribute it, through a network system, to all users connected to the said network system, satisfying their demand for heating, sanitary hot water and refrigeration.


At Agefred we install district heating and cooling, wherein the fluid power is delivered to service users through pipe networks, usually buried. Clients have in its buildings and facilities only the unit of exchange, transfer and measurement of energy.


The main benefit of these installations is the increase of energy efficiency, using renewable energies (biomass, solar energy, geothermal, etc.), building’s residual energies (surplus of heat or refrigeration, natural cooling, etc.), and high-efficiency production systems. Thus, with Agefred’s continuous management and maintenance, we can get to adjust optimally the generation to the demand, reducing energy consumption and air pollution.

Advantages of district heating and cooling:

  • They are installed quickly and for a large number of users.
  • They are a more energy-efficient solution.
  • Its investment is low and its maintenance less costly.
  • They provide greater comfort, improving environmental and air quality and producing less noises and vibrations.
  • They ensure safety, without risks of explosion or intoxication.
  • They offer a long-lasting thermal supply, with competitive thermal energy and high-reliability technical installations.
  • They are practical and aesthetic: they remove fireplaces and equipment on facades.

At Agefred we also develop EPC contracts (Engineering, Procurement & Construction) for power plants, with efficient and renewable energies, and their corresponding distribution networks for cold glycolated water for refrigeration, cold water for air conditioning, steam and hot water.
