"TOP TOWER"

MORE THAN 160,000

SQUARED METERS

COOLED WITH PREVA




 







The great tower RISE breaks the record as the tallest building in Latin America,
More than 400 meters will be effectively cooled thanks to Preva refrigerant gas technology!

Due to its high operation, the gas will provide greater performance and stability to each equipment connected within the Tower.

Refrigerant Properties

The properties that refrigerants used in air conditioning must have are:

  • The freezing point must be lower than any temperature that exists in the system to avoid freezing in the evaporator.

  • The latent heat of evaporation must be as high as possible for a small amount of liquid to absorb a large amount of heat.

  • The specific volume should be as low as possible to avoid large sizes in the suction and compression lines.

  • The density must be high to use small liquid lines.

  • The condensing pressures must be raised, to avoid leaks and reduce the condensing temperature.

  • They are not flammable, corrosive, or toxic liquids. In addition, they must have a low electrical conductivity.

  • They must be safe against the risks of fire and explosion.

  • The evaporation temperature should be below ambient temperature.

  • Its toxicity must be low, so that the risks in handling it are low.

  • Easy to mix with the lubricating oil used.
