Ice Hockey Dream Fulfilled

Today we received a wonderful letter from Fred Skelton. We supported Fred and his family last year to help him fulfil his dream of playing ice hockey for England. Keep reaching for the stars Eric and keep the team posted on your next adventures!


Dear Kind Donor,

I wanted to say a big thank you for your kind donation. My Dad said he had been told that you gave us some money so I could go away with England. It has helped me so much with my Ice Hockey. With your support, I was able to go to training camps and get new equipment that I needed.

This made a huge difference, and my new stick is brilliant. One of the best parts was being able to travel to Turku in Finland, with the England U13 team to play in a tournament. It was amazing. I even got an assist during one of the games. It felt great to be part of the team and play for my England. This is something I will always remember and be proud of. Without your help, I wouldn’t have been able to do this. You made it possible for me to follow my dream and improve as a player. Thank you so much for everything you have done for me.

Best wishes,

Fred Skelton

Fred also won an award this weekend also which the grant helped him achieve.

Thorne & Derrick | UK Master Distributor & Stockist for Eltherm

We would like to express our gratitude to Eltherm for hosting Thorne & Derrick at their headquarters in Burbach, Germany. This visit further solidified our strategic partnership, which we established last year.

Custom Engineered Heating Solutionsthe three-day technical product training session provided our team with an in-depth understanding of Eltherm’s comprehensive range of electrical heat tracing products, systems, and solutions. The training was delivered by relevant product managers and struck the perfect balance between practical and theoretical knowledge. We also appreciated the opportunity to tour their impressive production facility.

Experts in Innovation – One of the highlights of the trip was the detailed guide to the Eltherm Designer ATEX Software. Developed by Peter Schmidt and his team over 13 years, this software provides a powerful tool for calculating, selecting, and planning electrical heat tracing systems and solutions for vessels and tanks. We found the software to be incredibly user-friendly and a valuable resource for our technical sales engineers.

As a global engineering company with 14 locations across 5 continents, Eltherm is well-positioned to serve international markets and develop complete solutions for processes in production, storage, handling, and transport.

We would like to extend special thanks to Daniel Eichert for facilitating the trip, Heike Ritter for her hospitality, and the product managers and heat tracing experts who shared their knowledge and expertise with us. These individuals included Reimund Lotz, Frank Vogel, Thomas Stuff, Florian Duchard, Peter Schmidt, Markus Pfeifer, Martin Rings, and John Miller.

We are excited to apply the knowledge gained from this training session to comprehensively support our clients in the specification, design, and supply of reliable electrical heat tracing systems.

Thorne & Derrick specialise in providing specialist heating for industrial and hazardous areas including Eltherm’s heat tracing cables and heated hoses.

StuvEx Manufacturer of static earthing solutions for hazardous areas

StuvEx | Manufacturer of static earthing control solutions for hazardous areas for companies handling flammable and combustible products | ATEX, IECEx, SIL Compliant | Distributed by Thorne & Derrick International based in the UK.

Multi-Point Earthing System

When loading or unloading non-conductive, flammable liquids or powders, there is a risk of generating electrostatic discharges. If these discharges reach sufficient magnitude, they can instigate an explosion.

In order to perform these tasks safely, Thorne & Derrick together with StuvEx can provide a variety of systems designed to verify the grounding of conductive equipment.

“Tailored for trucks and railcars, our TES01 (IP) (EX) earthing control solution is engineered to prevent electrostatic discharges effectively. It includes a control unit, an earthing clamp, and either a cable or cable reel. This solution verifies the electrical connection to the clamp and detects the electrical capacitance between the truck and the earthing point, allowing adherence to the guidelines outlined in standard IEC 60079-32-1.,” explains Emilien Griffon, Sales Development Manager for France.

Multipoint Earthing Control System StuvEx Safe-Ground MGS01

 

A New Multi-Point Earthing System

The innovative StuvEx MGS01 Multi-Point Earthing System eliminates the need for multiple preventive devices! A single control unit can oversee up to 10 interconnected pieces of equipment (metal drums, industrial pipes, wagons, etc.) and verify their grounding simultaneously.

“This renders it not only a more convenient option but also a cost-effective one. Additionally, it comes as a complete kit with all necessary equipment. This includes cables and clamps, facilitating easier installation,” concludes Émilien Griffon.

Static Earthing For Road Tankers In Hazardous Areas


Truck Earthing

Preventing Hazardous Electrostatic Discharges

The total energy discharge of a person is about 10mJ. Likewise, small items such as metal buckets can be easily charged to an energy level of a few mJ, which is already more than the minimum ignition energy (MIE) required to ignite most flammable vapors.

Anyone walking on non-conductive floor coverings can be charged to a voltage as high as 20,000 V!

Prevent Hazardous Electrostatic Discharges

It is therefore not difficult to imagine that the energy discharge of a charged truck or bulk truck can reach up to 100 mJ. The above makes it clear that the correct earthing of a truck during loading is crucial.

For example, if a relatively small truck with a capacity of 1000 picoFarad is charged to 14 kV, it has a potential spark energy of 100mJ. Most hydrocarbon vapors and gases have MIE’s of less than 1mJ, it is clear that any tanker without proper earthing will be large potential ignition source in a hazardous area.

▶ Thorne & Derrick together with StuvEx supply static bonding, static earthing systems and grounding solutions to the hazardous area EX industries with over 35 years experience.


Why Earth a Truck?

  • Eliminate explosion risk occurring during truck loading/unloading
  • Safe discharge of electrostatic charge without sparking
  • Verification if the connection is to a tanker truck
  • Visual status indication and interlock with control system
  • Firm connection to ground during conveying
  • Continuous monitoring of the clamp connection

Norms and standards

The available standards, especially IEC / TS 60079-32-1 (Electrostatic hazards, guidance), describe processes where static charges can be generated, such as loading trucks and train wagons, filling and emptying of mobile tanks and vessels and mixing / mixing and transporting substances.

Other relevant standards: NFPA 77 (Recommended Practice for Static Electricity) and the API RP 2003 (Protection Against Ignitions Arising out of Static, Lightning, and Stray Currents). This standard specially highlights the loading of trucks, railway wagons, storage tanks and general work at petroleum products.

According to standards, effective earthing is the primary preventative to prevent hazardous electrostatic discharges and is the simplest, safest and most cost effective way to ensure that static hazards are properly controlled. Safely getting rid of static build-up will eliminate the risk of static discharges.


Static Earthing For Road Tankers In Hazardous Areas

Static Earthing For Road Tankers In Hazardous Areas

Truck Earthing Unit

IEC/TS 60079-32-1 only indicates that an earthing cable must be provided. In theory, a cable would therefore suffice.

Nevertheless, to avoid forgetting to earth the truck, an interlock earthing unit is recommended.

The truck may also already be electrically charged upon arrival at the unloading site. Hence, with a good earthing unit, the earthing clamp should ideally be insulated from the ground, and only connect to the “earth” after the clamp is connected to the tanker. This prevents the generation of a (potentially dangerous) spark when the clamp is attached to the truck.

Static Grounding System For Tank Trucks - StuvEx Safe-Ground TES01-V2

The TES01 truck earthing system is available in two versions:

  • TES01/IP (suitable for installation in ATEX zone 22)
  • TES01/EX (suitable for installation in  ATEX zone 1/2)

DIFFERENCES BETWEEN TES01-V1 and TES01-V2

TES01-V1
