The X40 Ultra Insulated Proximity Suit is a moderately insulated aluminized suit designed for industrial applications. The suit features a Z-Flex® aluminized outer shell which reflects 95% of radiant heat and tolerates radiant temperatures up to 3000°F (1650°C). In addition to providing outstanding protection, Z-Flex is also the most durable aluminized material available and will not de-laminate under even the most demanding conditions. A foil layer beneath the outer shell acts as a secondary defense against extreme temperatures, and a layer of fiberglass insulation provides protection even during extended exposure. This suit can be used in a wide range of industries including foundries, petrochemical plants, processing facilities, and other environments where workers are exposed to extreme temperatures.
