Seals for Alfa Laval heat exchanger

Alfa Laval duct heat exchangers are designed to operate in the heating system as well as in the cooling system. This heat exchanger is incredibly unique, it is great for working at high temperatures, pressures and fatigue loads. The peculiarity of the technology lies in the fact that soldering occurs with the melting of the material.

Description

Physical characteristics:

  • maximum possible heat transfer surface 4.4 m2
  • working pressure and temperature up to 1.6 megapascals at 160 degrees

In order to ensure proper operation of the heat exchanger, it is worth separating 2 environments: the environment that gives off heat and the receiving environment. This separation is possible with Alfa Laval plates and seals, which are made from different materials.

It is required in order to ensure the circulation and turbulence of fluids inside the heat exchanger itself and is designed to distinguish between such fluids in order to avoid hydraulic losses. An innovative solution was the use of nitrile-butadiene rubber as gaskets, this allows to isolate the space as much as possible, and is also resistant to harmful environments, which isolates the space as much as possible, is resistant to harmful environments, as well as chemical. reagents.

In heat exchangers where water is usually used as a working medium, rubber is practically indispensable; it can withstand temperatures from -20 to 140 degrees, and in the case of oil media from -30 to 160 degrees.
