Heat & Mass Transfer

Delivering premium quality, best performance and highest safety standards
 Tube and shell heat Exchanger

Heat exchanger

From straight tube heat exchangers to U-bundles, kettle type and more, all our heat exchangers are manufactured in Europe to the highest manufacturing standards and strictest quality controls and come with all the necessary approvals and certifications.

Each heat exchanger is individually designed and calculated. Thanks to many years of experience and our own thermodynamic and fluid dynamic process calculation programs, we can guarantee the highest performance and best results, whether in carbon steel, stainless steel or titanium and others.

Areas of application:

  • Evaporators
  • Condensers
  • Desorbers/boilers
  • Liquid-to-liquid heat exchangers
  • Economizer and other liquid-to-gas heat exchangers
  • Exhaust gas heat recuperators

We have extensive experience in the design of heat exchangers for binary mixture applications.

Rectification columns

The rectification column plays an essential role in every ammonia absorption refrigeration plant.

Over the years we gained extensive and in-depth experience in the design and construction of these columns, employing both, trays or plates and structured or filled packings of columns.

This expertise not only enhances our ability to effectively design and construct each column tailored to specific operational requirements, but it also empowers us to deliver a wide range of columns that serve various applications within the chemical industry.

This includes, but is not limited to, fundamental processes such as gas rectification, scrubbers and strippers.

High pressure condensate vessel

Ammonia separators and vessels

Beside heat exchanger and columns we can be your partner for the design and delivery of a wide range of pressure vessels for your industrial plant. Such as:

  • Ammonia separators
  • High pressure ammonia receivers
  • Liquid storage tanks
  • Receiver or separators for condensate in steam applications
  • and other applications

Specially if you need a complete vessel with level and/or pressure measurements, different service valves and safety valves mounted directly on the vessel. Get in contact with us to receive a quote adapted to your requirements.

All our vessels are designed according Pressure Equipment Directive (PED) and come with all required certifications according to the European regulations.
