The SHIELD plate and shell heat exchanger represents a new, revolutionary solution, ensuring not only increased flow turbulence, but also extensive heat exchange area.
The HEXONIC SHIELD plate and shell heat exchanger is a highly efficient device equipped with innovative heating plates and designed for demanding applications. It combines the thermal advantages of plate technology with the strength and pressure resistance associated with shell-type construction.
As an alternative to shell and tube exchangers, the SHIELD is designed to operate at high pressures and high temperatures. Its new construction delivers a more compact, lighter, and more efficient exchanger while remaining adaptable to individual operating requirements. The jagged channel design increases flow turbulence, improves heat exchange, reduces sediment accumulation, and helps lower overall pressure drop.
Key Features
-
High thermal effectivenessThe innovative JAG heating plate corrugation pattern increases the thermal effectiveness of the exchanger.
-
Suitable for high pressure and high temperature dutyThe SHIELD is specifically positioned as an alternative to shell and tube exchangers for high-pressure and high-temperature operation.

REINFORCED PLATE CONSTRUCTION
A plate pack is enclosed in a solid structure. The plates are joined in pairs using the laser welding method, and the plate pack is created by a robotic TIG welding system, making the unit leak proof and resistant to variable loads and thermal stresses.
VACUUM BRAZING FOR ENHANCED STRENGTH AND RELIABILITY
Additionally, there is the option of using vacuum brazing as a supplementary method for joining and reinforcing the plates, which allows for a significantly larger contact surface and increases the device’s strength. All of the plates are joined along the entire outer surface, at the ports, and additionally at several optimally selected points in the heat exchange area.

Applications
Frequently Asked Questions
The HEXONIC SHIELD is designed for demanding applications that require high thermal efficiency together with the ability to operate at high pressures and high temperatures. HEXONIC positions it as an alternative to shell and tube exchangers in these duties.
The SHIELD uses innovative JAG heating plates inside a shell construction, which increases flow turbulence, expands the heat exchange area, improves heat transfer, reduces sediment accumulation, and lowers pressure drops, while still providing a robust structure for demanding duties.
The plates are joined in pairs using laser welding, and the full plate pack is created with a robotic TIG welding system. This produces a leak-proof unit resistant to variable loads and thermal stresses. Optional vacuum brazing can also be used to further reinforce the plates.
HEXONIC lists refrigeration, industrial cooling and heating, economizers, gas heaters and coolers, CIP cleaning systems, aggressive media systems, oil cooling, chemical industry, petrochemical industry, power industry, HVAC, steam systems, ORC systems, and heat recovery among the target applications.
