Product catalog summary
Overview
Thermofin's ISTEAM steam coil heat exchangers are designed for efficient heat transfer from steam, with a focus on sustainability and durability. These exchangers are custom-built to meet specific industrial needs, particularly in sectors like pulp and paper.

Design and Features
The ISTEAM exchangers incorporate integrally bent U-tubes and a special casing design to minimize welding and allow for thermal expansion, reducing the risk of cracks. The design facilitates easy installation with both inlet and outlet connections at the same end.

Types of Steam Coils
  • Type Z: Widely used in the pulp and paper industry, designed for thermal expansion with connections at opposite ends for flexible installation.
  • Type VC: Designed for below-freezing air temperatures to prevent freezing condensate, featuring inclined tubes for gravity-assisted condensate flow.
  • Type AFZ: Ideal for extremely low air temperatures, promoting continuous purging of noncondensable gases and preventing condensate freezing.


Construction and Materials
ISTEAM coils are constructed with high standards, potentially registered with local jurisdictions or stamped per ASME. The use of extruded aluminum finned tubes enhances heat transfer and durability, allowing for cleaning with high-pressure water jets.

Options and Applications
  • Options: Air-tight construction, drawer-type casing for easy maintenance, and exterior surface protection with special coatings.
  • Applications: Include air preheaters for industrial boilers, heating coils for pulp and paper drying, heat recovery, room comfort heating, wood drying coils, and chemical process heating.


Installation and Maintenance
The longevity of steam coils depends on proper installation, including adequate connections and drainage design to prevent corrosion and erosion. In corrosive environments, materials like stainless steel may be used.

Conclusion
Thermofin's ISTEAM steam coils are engineered for robust performance and adaptability, ensuring efficient heat exchange across various industrial applications.

Aéroréfrigérant ISTEAM : Custom Built Steam Coils The ISTEAM exchanger was the first heat exchanger product designed by Thermofin. Over the years, its evolving design has benefited from Thermofin’s significant experience with thousands of installed units. The ISTEAM coil’s purpose is to transfer heat from steam. Steam, sometimes referred to as a “wild beast” by experienced boiler operators, can be unpredictable if all aspects of the heat exchanger, either thermal or mechanical, are not controlled properly. Accordingly, Thermofin is pleased to offer a wide range of specially designed steam heat...

This steam coil was specifically designed for air temperatures that are below freezing, to prevent the costly consequences of freezing condensate. The concept is to insert an open-ended shorter distribution tube within an outer fin tube thus allowing the condensate that is flowing in the annular clearance to be kept warm by the steam condensing in the distribution tube. The tubes are inclined in order to promote the condensate flow by gravity. Consequently, the type VC steam coils always have both their inlet and outlet connections at the same end of the coil. Installation may be horizontal or...

Options To better suit your exacting needs, Thermofin offers an array of options such as: Air-tight construction: This option is usually needed when the airside pressure is higher than the ambient conditions of the site. Drawer type: The design of a casing that incorporates the concept of a drawer that contains the exchanger simplifies maintenance and replacement of the unit. No need to disassemble the air ducts to remove the steam coil heat exchanger! Exterior surface protection: special coatings (‘‘Heresite’’, hot dip galvanizing, special paint, etc.) that help protect the fins and/or the heat...
