A new division of NUCAP Industries, NUCAP Energy (NUCAP) has launched the unique GRIPMetal™ surface enhancement technology for improved thermal energy transfer and energy storage.

Working with metal substrates including stainless steel, aluminum, copper, brass, and titanium, NUCAP’s GRIPMetal™ manufacturing process substantially improves thermal energy transfer by increasing surface area through a non-subtractive process without increasing weight. Furthermore, when GRIPMetal™ is used as a component in composite materials, it significantly improves the structural strength of the composites. NUCAP has pioneered the use of GRIPMetal™ to improve heat transfer effectiveness in composites. GRIPMetal technology increases the overall heat transfer rate between composite material layers with thousands of hooks penetrating adjacent materials.

Working to create smaller, lighter and stronger components using GRIPMetal™ material, NUCAP works with manufacturers to reduce costs as well as improve thermal transfer and thermal storage efficiency. By supporting innovation in the power and renewable energy sectors, as well as key industries including aerospace, transportation, and computing, NUCAP aims to create a more sustainable and efficient future.

Patented materials for heat transfer and energy in power generation

The NUCAP fabricating process matches materials to customers’ requirements, with any metal, shape and hook geometry, as well as the option for one or double side enhancement.

Highlights of NUCAP technology include:

  • Up to 80% more surface area without increasing weight
  • Increasing structural strength of composite materials using GRIPMetal™
  • Substantially improving thermal conductivity between composite material layers

Mobile transformers with smaller footprints

Climate change and ageing infrastructure are increasing the need for mobile transformers as the size of a transformer can directly affect the cost of manufacture and operation. Smaller transformers save materials, space, and operations and logistics costs, allowing increasing power demands to be more easily met.

For systems using viscous liquids such as oil in transformers’ cooling circuits, surface modification technology allows for cooling system size to be reduced by up to 40%. This results in easier and cost-effective logistics for mobile transformers. Fewer materials required to build and operate a transformer also aids in material conservation efforts.

Thermal energy management and storage

Various forms of thermal energy transfer can be improved by NUCAP surface modifications. GRIPMetal™ provides a suitable interface for any combination of gas, liquid or solid heat transfer media.

Whole industries can be transformed by changing the size, weight and efficiency of existing products. Zero-gravity heat exchangers for spacecraft and improved energy storage and performance for electric vehicles are some of the innovations from NUCAP.

NUCAP Energy works to hone its engineered metal surface enhancements through collaborations with universities and researchers across the key industries we supply.

Renewable Energy

NUCAP develops innovative solutions for capturing, storing, and using solar thermal and waste heat energy in buildings to reduce fossil fuel usage.

GRIPMetal™ surface modification technology can be used to increase the efficiency of both air- and hydronic-based solar thermal collectors. With enhanced heat exchange surfaces and high-efficiency collectors, the heating needs of an entire building can be met through thermal energy absorption.

Surface enhancement can also benefit hybrid photovoltaic-thermal collectors. More efficient panel cooling results in more efficient electricity generation, with recovered heat used for thermal needs.

NUCAP GRIPMetal™-based composites can also be used to recover waste heat from gas, liquid or solid sources, as well as provide thermally active cladding for buildings. As cladding, NUCAP’s surface enhancement fully integrates into a building, providing the benefits of supplementary heating and cooling along with an ‘invisible’ appearance.

Increasing the efficiency of heat recovery processes reduces costs, while sourcing district heating and seasonal heat storage from renewable solar power will help create zero-emission buildings.
