Innovative Surface Modification for Enhanced Heat Transfer Solutions.


NUCAP ENERGY applies 18 years of NUCAP’s experience and state-of-the-art manufacturing technology of NUCAP Retention System (NRS) to thermal energy transfer and storage applications.

What is Nucap Energy?

Grip Metal technology provides surface modification of metallic materials that dramatically raises heat transfer rate by increasing surface area and acting as a perfect turbulator.

The enhanced surface pattern can be applied on sheet metal (coils or flat sheets) and tubes (including micro-channel extrusions).

Our technology increases surface area by up to 60% when compared to a flat surface of the same footprint; additionally the modified surface operates as a turbulator. These features allow for reduced size and increased output of your heat exchange application.

By using combination of our micro-hooks together with micro-channel technology you can accomplish up to threefold increase in heat transfer rate.

Industry USE.

GRIP Metal becomes an upgrade to currently used material in heat exchange applications, requiring minimal changes to existing design and manufacturing process.

Manufacturers of HVAC and refrigeration equipment, energy recovery systems, heat exchangers (shell-and-tube and plate), electronics cooling systems, and energy storage systems would instantly benefit from modifying their existing products using our material.

Examples of products that can benefit from use of our materials include, but are not limited to:

  • Core heat exchangers for heat recovery units
  • Finned tubes (coils and radiators)
  • Automotive coolers and radiators (including battery coolers and Exhaust Gas Recirculation Coolers)
  • Primary heat exchangers for gas boilers and furnaces
  • Heat sinks for electronic equipment
  • Heat exchangers for heat pumps (condensers and evaporators)
  • Air handlers (fan-coil units)

Our R&D and engineering services, as well as testing, are available when required.

Materials We Provide

NUCAP ENERGY can customize surface enhancement to meet specific requirements of our clients (material, size and shape of the hook, shape of the elements). Enhancements can be exclusively engineered for a specific application.
