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.
