Brazed Plate Heat Exchangers (L, LUNA, R, Safe Plate, AS)

Brazed plate heat exchangers ensure turbulent flow through a specially designed corrugated pattern on the heat transfer plates, which significantly enhances heat transfer efficiency. Their hermetically sealed construction, achieved through vacuum brazing with copper or stainless LUNA brazing, guarantees long-term reliability. 

The compact design allows for maximum space savings, while low operating costs and minimal maintenance make them a cost-effective solution. These exchangers are engineered for demanding conditions, with customizable plate numbers, connections, and flow rates to suit a wide range of applications.

Drum and Tube Heat Exchangers (B, DNA, Pline, REV, REV TI, ST, TI)

Drum and Tube Heat Exchangers consist of an external shell with a bundle of tubes inside. Due to various construction types and a wide range of dimensions, these exchangers are widely used in industry, heating systems, and swimming pools. They use spiral tubes that create turbulent rotational flow, effectively doubling the heat transfer coefficient. They feature low pressure drop with no dead zones, while the compact design allows for a large exchange surface. Ideal for high flow rates, and the stainless steel construction ensures corrosion resistance and long service life.

Drum-Type Spiral Heat Exchangers (H, HAD, JAD, S, RAD)

Drum-Type Heat Exchangers with Spiral Tubes achieve a higher heat transfer coefficient compared to standard shell-and-tube heat exchangers.
Their compact dimensions and high efficiency are highly valued by installers and end-users alike. 

The spiral tubes create turbulent flow, enhancing heat transfer while maintaining a low pressure drop without dead zones. They save space, are ideal for high flow rates, and corrosion-resistant thanks to the X-design of the corrugated tubes.

Plate-and-Drum Heat Exchangers (SHIELD)

As an alternative to traditional shell-and-tube heat exchangers, these units are ideal for operation under high pressure and temperature conditions. The design of the new SHIELD model offers a more compact, lightweight, and above all, more efficient solution, perfectly adaptable to individual requirements. 

The special plate shape reduces flow resistance, while vacuum brazing ensures durability. The optimized volume enables a compact design, suitable for pressures up to 100 bar and temperatures up to 450°C, ensuring reliability and efficiency.

Frequently asked questions about
heat exchangers

Where are heat exchangers used?

They are used in HVAC systems, cooling systems, the food and pharmaceutical industries, energy sector, chemical industry, purification, petrochemicals, as well as in heating systems and swimming pool installations.
By design, they are classified as brazed, plate, tubular, and industrial heat exchangers, each type having specific applications and advantages.
They consist of a shell with a bundle of tubes inside and are used in industry and heating systems due to their wide range of sizes and designs.
The selection of the right heat exchanger depends on the type of fluids, operating parameters, and specific application requirements. It is important to consider viscosity, corrosiveness, pressure, temperature, flow rate, as they directly affect heat transfer efficiency. The environment in which the exchanger will be used should also be taken into account.
Proper maintenance of heat exchangers includes regular cleaning, monitoring operating parameters, and preventing deposits buildup which can reduce efficiency. It is important to remove dirt and buildup, especially in models with enclosed passages, to preserve optimal heat transfer. For exchangers with a detachable design, mechanical cleaning is useful for removing stubborn deposits.
