Heat transfer.

Heat transfer is important process in many industrial applications, which take thermal energy from one fluid into another fluid. Heat transfer has so wide applications that almost no single industry could work out without heat transfer process technology and its equipments.

We are specialised in the design and manufacture of air-cooled heat exchangers and cooled condensers (ACC), plate heat exchangers and shell tube heat exchangers etc.

Not only do we have the required know-how, but we are also very flexible in handling our projects. With both our experience and the application of the best available technology, we have become well known in several industries, specifically the chemical industry.

Air-cooled heat exchangers and cooled condensers

Design and construction of our air-cooled heat exchangers and cooled condensers carried out by our own engineering departments and adhere to both national and international standards and customer specifications. Through all stages of engineering we use professional software applications.
To ensure and document our quality we work with a well-established quality-management system, which is certified according to ISO 9001:2008.

Process air coolers for the chemical industry

Process cooling with air as cooling medium is used successfully in the chemical industry and is becoming more important with steadily increasing costs for cooling water. At locations where cooling water is not available it is often the only possibility for the cooling of process streams.
Process air coolers are designed and manufactured according to customer-specific requirements and commonly used industry standards such as Hafe 661. The process conditions can range from vacuum to pressures up to 300 bar.

Air-cooled heat exchangers

For the heat exchanger bundles we regularly process carbon steel, stainless steel and special materials such as duplex. Others can be used upon request. Our supply of air-cooled heat exchangers comprises of:

  • Complete design engineering
  • Heat-exchanger bundles with welded bonnet headers, removable cover plates or plug-headers
  • Horizontal, vertical, A-frame or V-frame arrangement
  • Axial fans in forced or induced draught installation
  • Complete steel construction with ladders and walkways
  • Auxiliary equipment such as frequency converters and control cabinets
  • Erection on site and commissioning support

Air-cooled condensers

Air cooled condensers (ACC) are used for the condensation of turbine exhaust steam in power plants. The rejected heat is directly transferred to the ambient air through fin-tube heat exchangers.The ACC units have an A-frame construction with cooling fans in forced draught installation. The steam is distributed via a steam duct to the heat exchanger bundles. Each bundle has an integrated reflux part to achieve reliable condensation and removal of non-condensables. Our ACC's include:

  • Complete design engineering
  • Heat exchanger bundles with aluminium finned tubes
  • Steel construction including wind wall
  • Axial fans in forced draught installation
  • Steam duct
  • Piping for condensate system
  • Evacuation unit
  • Condensate tank including required pumps
  • Cabling, switchgear cabinets, instrumentation
  • Erection on site and commissioning

We are able to generate innovative solutions for customers among many kinds of industries (chemical, petrochemical, pharmaceutical, and food).

We could provide reliable and versatile Heat transfer units for a wide range of various applications:

  • Welded plate heat exchangers
  • Plate and Gasket heat exchangers
  • Shell and Tube heat exchangers with straight or corrugated tubes
  • Fin tube heat exchangers
  • Electric heaters

Each Heat transfer unit is sized and built following accurate thermal and mechanical input data. Exotic materials of construction together with the use of innovative manufacturing techniques are widening the scope of potential reliable and trouble free applications.

ALL WELDED PLATE HEAT EXCHANGER FROM VERY EASY TO CLEAN UNITS TO FULLY WELDED DESIGN

Originally based on the needs of the textile and chemical industries, these exchangers have been developed to meet the growing demand of a wide variety of new applications in many different process industries (Chemical, Pharmaceutical, Sugar, Hydrometallurgy).

The thermal performance of these exchangers makes them particularly attractive. In addition, their basic design gives significant advantages relative to other types of exchangers, for example of high flow capacity and compact design up to 200 M2/M3 can be achieved.

pressure vessels, columns, and shell and tube heat exchangers

We also leading manufacturer of pressure vessels, columns, and shell and tube heat exchangers. We serve the chemical and petrochemical industry, offshore, pulp and paper, food and pharmaceuticals, nuclear power plants and distilleries.

Distillation and absorption columns, heat exchangers and pressure vessels

Our main area of expertise is in the production of distillation and absorption columns, shell and tube heat exchangers and pressure vessels. Each project we work on is completely unique and each construction is adapted to the clients specific process needs.

Heat exchangers for chemicals applications

Our heat exchangers are used for the most variable applications, principally in the chemical and petrochemical industry. We specialise in tailor-made units that are optimised according to application and the customer's requirements.

As the applications are so varied, we have to deal with many different media such as air, fresh water, salt water, steam oils and the whole spectrum of process solutions. We can also replace and re-tube an existing heat exchanger.

Shells and complete columns

We design and manufacture shells for columns as well as complete columns with valve trays, bubble cap trays and packed columns. Platforms, ladders, etc. can also be included in the delivery. Mechanical design as well as wind load and earthquake calculations can be carried out where required.

Pressure vessels

We construct and manufacture most types of pressure vessel, including those with or without jackets, for outside cooling / heating coils of half tube section, with agitators, inner coils and baffles.

Quality-assured pressure vessels and heat exchangers

We increasingly assists customers with maintenance in relation to production stops.
Among others, we are certified in accordance with:

  • ASME U-stamp
  • China-stamp (manufacture license for special equipment, China, pressure vessels A2)
  • Hp0 (welding certification according to the German system AD2000)
  • Achilles (off-shore certification according to Denmark and Norway)
  • ISO 9001-2008 with EN 3834 (quality assurance for welding)
