The GRP Ex enclosures produced by HARDO are durable and reliable solutions for applications requiring protection in explosion hazard Zones. Made from antistatic glass-reinforced polyester (GRP), they provide maximum protection against corrosion and UV radiation. They are characterized by an IP 65/66 protection rating, the ability to mount various types of cable glands, and a wide operating temperature range from -50°C to +95°C. They hold ATEX and IECEx certifications. Capable of operating with a nominal voltage up to 1000V and a nominal current up to 160A, they are an ideal choice for a variety of industrial applications.

Glass fibre reinforced polyester used to manufacture the HTBP series terminal boxes have been selected to grant the maximum protection against highly corrosive agents and maximum UV protection. Cover screws are made of stainless steel AISI 316L. Cover gasket is made of silicone. Internal mounting screws are made of non-corrosive material. Wide variety of enclosure sizes allows to accommodate all customers' requests.

Protection of Glass Reinforced Plastic (GRP) Ex Enclosures for Explosion Hazard Zones

Glass Reinforced Plastic (GRP) Ex enclosures with markings:

  1. gases and vapors: II 2 G Ex db eb ia/ib mb IIC/IIB T6 Gb
  2. dusts: II 2 D Ex tb IIIC T85°C Db

are designed to ensure safety and protection in explosion hazard environments. Their unique design and applied safety technologies are key to protecting electrical and electronic equipment in the industry. Below are the main advantages of these enclosures and the protections they offer. An explanation of the applied types of protection for the enclosure and its components is presented below:

  • eb - increased safety (PN-EN 60079-7)
  • tb - protection of equipment against ignition of dust by enclosure (PN-EN 60079-31)
  • db - explosion protection in flameproof enclosures (PN-EN 60079-1)
  • ia/ib - intrinsically safe (PN-EN 60079-11)
  • mb - encapsulation of devices (PN-EN 60079-18)


Advantages of Glass Reinforced Plastic (GRP) Ex Enclosures

  1. Durability and Resistance to Atmospheric Conditions: Glass reinforced plastic is incredibly durable and resistant to varying atmospheric conditions, ensuring long-lasting protection of devices.
  2. Chemical Resistance: This material is resistant to a wide range of chemical substances, making the enclosures an ideal solution for the chemical industry and other environments with a high risk of corrosion.
  3. High Electrical Insulation: Glass reinforced plastic offers excellent electrical insulation, which is crucial for ensuring safety in Zones at risk of explosion.
  4. Lightweight: Despite its strength and resistance, this material is significantly lighter than metal, facilitating the installation and handling of enclosures.
