Ohio Valley Industrial Services manufactures a complete line of removable-reusable insulation jackets to meet most industrial, commercial and laboratory insulating requirements. HotCaps™ are the cost effective way to insulate valves, flanges, expansion joints, and other components, providing the user with the energy savings associated with permanent insulation and the flexibility of reusing the cover.
HotCaps™ can be fabricated from a wide range of materials depending upon the system temperature and specific service environment. The insulation jackets are made from various industrial grades of woven fiberglass fabric encapsulating high temperature insulation. Silicone impregnated fiberglass cloth jacketing provides excellent oil, moisture, and abrasion resistance, while Teflon coated fiberglass is recommended for corrosive environments. Fiberglass cloths laminated with metal foil are also available for applications requiring a vapor or hydrocarbon barrier. HotCaps™ are used in applications ranging form cryogenic temperatures to 1800 F.
