Hauff-Technik Puts Down Roots in the UK
March 2nd, 2023PR | BY Hauff-Technik | 02.03.2023
Hauff-Technik, a leading manufacturer of sealing systems for cables, pipes and building entries has put down roots in the UK.
With the new subsidary in Chesterfield in the heart of England, Hauff-Technik are strengthening their sales activities in United Kingdom.
Today, we are establishing our next national company: Hauff-Technik UNITED KINGDOM Ltd.
The establishment of a further subsidiary is intended to respond more intensively to customer needs, increase competitiveness and achieve even faster market development.
The newly founded Hauff-Technik UK Ltd. is based in Chesterfield, UK and is headed by Thomas Koelle and Jan Holly as Managing Directors.
“By being able to supply a wide range of products from stock, we have fast lead times for delivery within 24 hours on the UK mainland,” says Thomas Koelle. “With a dedicated team of two field sales representatives, we do not only offer direct local contact, but also offer in-house training as well as on-site support and advice,” adds Jan Holly.
“The foundation underlines our long-term strategic interest in the British market and also its important position within Europe. We would like to significantly expand our sales efforts in the UK in the future and are now laying the foundation for this,” comments Dr. Michael Seibold, Managing Director of the parent company Hauff-Technik, based in Hermaringen in Baden-Wuerttemberg.
Previously, the company had three subsidiaries: Hauff-Technik GRIDCOM GmbH in nearby Rosenberg, Hauff-Technik MIDDLE EAST LLC in the United Arab Emirates, and Hauff- Technik SWISS AG in Switzerland.

Offshore Wind Power Cable Management | Top 5 Challenges
August 31st, 2022
Top 5 Challenges In Wind Power Cable Management
Offshore Wind Power Cable Management
Roxtec Top 5 Challenges
Thorne & Derrick are Approved Distributors for Roxtec, the leading manufacturer of sealing solutions for cables and pipes, to protect electricity Transmission & Distribution assets including windfarm substations against water ingress, gas migration and fire hazards.
Below Roxtec have compiled the top 5 most common issues we all struggle with on offshore substations.
1. Specifications & Certificates
We all want to ensure safety and operational reliability, and use high quality products to deliver the best result we can. Therefore, we often meet specifications and requirements demanding a multitude of certificates. However, it is not guaranteed that all types of cable sealing methods are approved.
The best thing would be to find a sealing solution that has passed all tests and certifications.
2. Uncertain Estimates
It can be difficult to know how many cables or pipes, or what size power and instrumentation cables, we need to route. We can never be sure about making the right openings, or about how to seal all those penetrations. Even the best of estimates cannot predict all late design changes.
What we need is a sealing system that is as adaptable as possible to the number and size of cables, pipes or openings. It should be so flexible that we would be able to have spare capacity.
3. Hard Cables To Handle
It is difficult, or almost impossible, to move and bend a large high-voltage or medium-voltage power cable into the desired position for routing through a deck or bulkhead. It takes a lot of time to reorganize the routing path in order to gain a couple of millimeters of bending radius.
What you need is a solution where you can position and apply a seal to fit around the cables, even if they are in an off-center position.
4. Tricky Design Work
Given the issues mentioned above, the work of design engineers often becomes a nightmare. We need to plan, calculate and design in cable and pipe penetrations at an early stage considering both rollout and maintenance. Sometimes, it means recalculating each opening.
Imagine a web-based design tool that we can use to design and redesign transits in no time.
5. Time-Consuming Installation
We know renewables can save the climate, and we know speed is crucial and time is money. Therefore, it is so frustrating to struggle with sealing solutions that are neither flexible nor easy to install. We cannot accept that project plans fail due to complicated installation work tasks. We should only engage suppliers of user-friendly products who will also train the installation team.
Roxtec provides offshore wind farms with an “all in one” solution for cable entry sealing, cable management and vibration damping. Standardise with Roxtec seals for efficient offshore windfarm cable protection design, quick roll-out and certified protection – cables are securely fixed, sealed and cable lifetime is extended.

Cable Sealing Using Roxtec
Roxtec cable seals are used in cable vaults, duct banks, electrical substations, trenches and M&E building services protecting low, medium and high voltage power systems against numerous external risk factors:
- Fire – A60, H120 Class bulkhead sealing for offshore classification against jet-fire or spray and prevention of suffocating smoke spread
- Gas – ensure complete tightness against air and gas pressure or migration through cable ducts with DSEAR compliance
- Water – prevent flood and water penetration into substations and buildings – avoid humidity and partial discharge conditions
- Cables – withstand cable bending load in heavy power and high voltage cable seal applications
- Pressure – protect against catastrophic sudden or constant pressure
- Electrical – protect cables and electrical infrastructure against EMI, EMP and lightning strike effects
- Particles – control levels of of dirt, dust, chemical and fumigants from entering buildings, cable ducts and substations
- Blast – protect against vibration, shock-waves and the risk of explosion in industrial and hazardous area locations
Cable Transits – Sealing Cables & Pipes
Cable Transits
Roxtec cable transits are used to prevent water, gas, fire, dust and rodents from entering cable duct openings and potentially causing damage to cables and other electrical infrastructure.
Cable transit systems can be designed for sealing medium/high voltage substations including 11kV/33kV and “triplex” type cables in single, multiple or trefoil configuration.
Roxtec modular cable transit seals are based upon a rubber design with seals that are constructed of a number of removable layers to secure a watertight, gas tight and fire proof seal around the cable or pipe – the range includes rectangular transits and round transits to fit a variety of pipes and cable sizes.
Cable transit products ensure safety, reliability and efficiency by providing an effective, dependable seal around cables and pipes through an opening, penetration or duct.

Nofirno Sealing System Successfully Tested for Use in Explosive Environments
July 13th, 2021
Nofirno
NOFIRNO systems are used to seal cable ducts in an extensive range of Process industry sectors including the fine and speciality chemicals, petrochemicals, pharmaceuticals, hydrogen and polymers manufacturing sectors. The NOFIRNO range of duct seals are used to protect against water ingress, gas migration, fire spread and rodent infestation into electrical substations and buildings through LV MV HV cable ducting systems.
ATEX directive requirements can be imposed for specific uses in hazardous area locations (Zone 1/2 Flammable Gas & Zone 21/22 Combustible Dust) where there is a potential risk of explosion. Kiwa has thus investigated the extent to which the NOFIRNO sealing system (from Beele Engineering) fulfils ATEX directive 2014/34/EU.
Comprised of rubber and filler sleeves and sealant, the system is used to treat transit openings for cables and pipes in walls, floors, bulkheads or decks, so that they are fire-resistant and sealed against gas, smoke and water. Kiwa’s research has shown that NOFIRNO is extremely suitable for use in environments such as those covered by the ATEX directive and described in the European standard EN 1127-1 ‘Explosive atmospheres – Explosion prevention and protection – Part 1: Basic concepts and methodology’.
Because the NOFIRNO sealant, NOFIRNO rubber sleeves and the complete NOFIRNO sealing system do not fulfil an autonomous role and are not equipment in the sense of the ATEX directive, the risk evaluation focused on use of the NOFIRNO in cable and pipe transits. All possible ignition sources related to the sealing system were also investigated.
Among the possible ignition sources which were assessed, were hot surfaces, flames and hot gases (including hot particles), mechanically-generated sparks, electrical equipment and power leakages, cathodic corrosion protection, static electricity, lightning, electromagnetic and ionising radiation, ultrasonic sound waves, adiabatic compression and shockwaves and exothermic reactions, including materials self-igniting.
Kiwa concluded that for all hazardous situations as described in EN 1127-1, there is no ignition source for NOFIRNO sealant, NOFIRNO rubber sleeves, NOFIRNO rubber filling sleeves and the complete, installed NOFIRNO system.
CSD NOFIRNO DUCT SEAL SYSTEM
Watertight, Gastight & Fire Protection & Sealing for Cables & Duct Entries
CSD NOFIRNO duct seals is a multi-cable and pipe transit sealing system designed specifically for cable duct seals and building entries providing an effective and simple solution protecting against flood water and gas ingress.
NOFIRNO duct seals consist of rubber multi sleeves which are in bonded strips of 10 sleeves and a high quality silicone based sealant which are quicker and easier to install than the CSD standard RISE duct seals.
The bonded sleeves can be easily torn off for filling smaller gaps and using cutting tool sleeves can be quickly slit to allow fitting around cables ensuring cable separation – NOFIRNO duct seals are also used to pack the free space, providing a backing for the application of the cable sealant.
Completing the seal with a 20mm layer of NOFIRNO sealant will provide a technically advanced and high performance duct seal. View the complete range of CSD Sealing Systems to protect against damage caused by water ingress, gas spread or fire/flame to cables and ducts.
