Heat Exchangers & Thermal Systems

Engineered for Energy Efficiency & Process Reliability

At Dimarke, we provide a wide range of heat exchangers and thermal process systems designed to meet the needs of oil & gas, petrochemical, chemical, power, and food industries.

Efficient heat transfer is the backbone of industrial operations — enabling energy savings, safe operations, and product quality. With 30+ years of expertise and global partnerships, Dimarke ensures our clients have access to world-class equipment tailored to their projects.

Heat Exchangers

Shell & Tube Heat Exchangers

  • One of the most common designs, consisting of a cylindrical shell and tube bundles.
  • Used for liquid-to-liquid applications, condensers, and steam generators.
  • Applications: crude oil refining, natural gas processing, chemical plants, power generation.

Plate Heat Exchangers

  • Made of stacked stainless steel or titanium plates pressed together.
  • Provide high efficiency in a compact design.
  • Applications: oil coolers, central heating systems, food and beverage processing.

Air Cooled (Fin-Fan) Heat Exchangers

  • Use ambient air as the cooling medium.
  • Equipped with aluminum or copper fins for optimal heat dissipation.
  • Applications: refineries, petrochemical plants, and power stations.

Double Pipe Heat Exchangers

  • Simple design with one pipe inside another.
  • Ideal for low-capacity heating or cooling processes.
  • Applications: chemical and small-scale industrial operations.

Thermal Separation Systems

Dimarke also supplies equipment for drying, evaporation, and crystallization — processes essential for separating and purifying materials in industrial applications.

Drying Equipment

  • Tray Dryers – hot air circulates around trays for gentle drying.
  • Steam Tube Dryers – use steam inside tubes within a rotating drum.
  • Tube Bundle Dryers – steam-heated tube bundles for effective moisture removal.
  • Drum/Roller Dryers – material spread on a heated drum surface for rapid drying.

Crystallization Systems

  • Recover dissolved compounds or prevent scaling in process industries.
  • Scraped Surface Tube Crystallizers and Archimedes Tube Crystallizers available.
  • Other models such as DTB and Oslo crystallizers offered upon request.

Evaporation Equipment

  • Forced Circulation Evaporators – liquid pumped at high pressure through heat exchangers.
  • MVR (Mechanical Vapor Recompression) Evaporators – reuse vapor as a heat source for efficiency.
  • Agitated Thin Film / Wiped Film Evaporators – spread liquid in thin layers for rapid evaporation.
