The IECEx / ATEX / SIL 2 / cCSAus certified Earth-Rite RTR is the most advanced system for protecting personnel and plant assets from static hazards during tank truck loading and unloading operations.
The Earth-Rite RTR utilizes patented Tri-Mode Technology to provide safe and reliable grounding of the road tanker by ensuring:
- Positive and verified connection to a tank trucks
- Verified low resistance connection to true earth (ground)
- A continuously monitored tanker-earth connection of less than 10 ohms for the duration of the product transfer process
When these parameters are confirmed, the RTR permits the transfer of product. Any static generated on the tank truck by the transfer process is immediately transferred to earth. The Earth-Rite RTR operates with a Universal Grounding Clamp and does not require any special equipment to be installed on tank trucks. It may be used with all common types of Bulk Tankers without any special modifications.
Features
- New explosion-proof cast aluminum enclosure is robust and lightweight (copper free)
- LED indicators are viewed through a window that is assembled to the enclosure lid
- Three green LEDs pulse continuously during the transfer process when positive ground condition is established
- Simple pulsing effect informs personnel that the system is continuously monitoring the condition of the ground connection
- Patented tri-mode technology ensures the system only goes permissive (permitting product transfer) when the three parameters required for safe grounding are confirmed
- Ensures the system cannot be activated by connection to parts of the tanker truck not electrically continuous with the truck's container or when the system does not detect a low resistance connection to true earth (ground)
- Tungsten Carbide pointed contacts to ease good metal to metal contact and spiral cable in-line-quick-connect feature
