New DEi Under-Hood Protection Is Good as Gold

AVON LAKE, OH (09.01.2020) – To keep under-hood wires, cables and hoses cool and protected, it pays to go for the GOLD.

Design Engineering, Inc.’s new GOLD Line Sleeving is manufactured from the company’s high-temperature Metalized Polyimide lamination and bonded to a robust, 20-oz heat-treated glass fiber base material. Available in Sheaths, Shrouds and a Cover, DEI’s GOLD Sleeving products not only protect components, but also keep them cool in the most demanding applications.

Able to reflect direct heat up to 800 ̊ F, GOLD Line Sleeving is the perfect defense for critical lines, air intakes and hoses against the damaging effects of high temperatures.

“Only available from DEI, our new GOLD Line Sleeving was shown to offer a 67% reflection of heat during heat flux testing,” said Mike Buca of DEI. “Furthermore, it has been tested to FSTM 191.5100 and ASTM D1117 standards for total protection.”

Heat Sheath GOLD is available in five sizes from 3/4″x36″ to 2-1/4″x36″. The Sheaths feature a lock weave pattern and high-temperature hook-and-loop fastening system for fast, secure installation. Heat Sheath GOLD is also available in custom dimensions.

Heat Shroud GOLD is available in 1/2″-1-1/4″x36″ and 2” – 2-1/2”x36 sizes and constructed from the same high-temperature materials as the Sheaths, but with the added convenience of a hook-and-loop closure with open edges. Installers simply wrap the Shroud around whatever needs protection and close the edges, without the need to remove one end of the connected wires, cables or hoses. Heat Shroud GOLD is also available in custom dimensions.

Cool Cover GOLD is primarily used to cover cold air tubes to reflect heat for a cooler, denser and more powerful air charge. Cool Cover GOLD measures 28” in length, which can be trimmed to length and built to accommodate up to 4” O.D. air tubes. Constructed with a hook & loop edge design, it is designed for ease of installation… easy on, easy off.

AVON LAKE, OH (07.03.2020) – When it comes to technologically advanced turbocharger protection, Design Engineering, Inc. has again raised the bar with its new GEN-3 Titanium Turbo Shields with LR Technology.

Featuring a silicone-coated outer layer, multiple stainless steel and silica inner layers, and enhanced seam strength, the GEN-3 Titanium Turbo Shield was made to be the strongest, most heat-resistant shield available anywhere.

“By developing advanced textiles and diving deep into what is needed to control turbo heat, we incorporated all our experience to build the absolute best turbo shield on the market— the GEN-3 Titanium Turbo Shield,” said Mike Buca DEI Product Manager.

  • Outer Shell—DEI’s Titanium material with LR Technology is coated in silicone to insulate and hold up under extreme conditions;
  • Insulation Layer—A thick layer of silica insulation keeps heat inside the turbo shield and turbo housing;
  • Inner Layer—A blend of stainless steel, glass fiber and silicone add to the GEN-3 insulating and thermal properties;
  • Inner Cover—A stainless steel mesh is incorporated as a protective barrier and serves as an air gap between the mesh and inner layer fabric. Constructed to hold up against the highest temperatures, the innovative mesh won’t break down or become brittle with heat.

Customers can choose to purchase just the shield or a Complete Kit that includes the shield as well as a 2″-by-15-foot roll of Titanium Exhaust Wrap for down pipes, two 20″ stainless steel Locking Ties and 5 feet of safety wire used to secure the shield.
