Dinnteco DDCE magma – High-Temperature Lightning Prevention Device (Stainless Steel & Alumina)

The Dinnteco DDCE magma is a lightning prevention device made of stainless steel and alumina for continuous operation in extreme thermal environments — burners, flare stacks, chimneys and other structures exposed to very high temperatures (always avoiding direct flame). It applies the same patented DDCE principle as the rest of the range. Made by Dinnteco (Spain), which has more than 20 years of experience, over 10,000 units installed and a presence in more than 40 countries.

How DDCE prevention works

A conventional lightning rod — and an ESE (early streamer emission) arrester — is designed to attract the strike and carry its current to earth. The DDCE works the other way round: it continuously balances the electric field that builds up between a storm cloud and the structure, keeping it below the level at which an upward leader forms, so the strike is prevented from landing on the protected area.

Its patented design (Government of India Patent No. 425967, "Device for balancing variable electric fields") lets a controlled, low-intensity leakage current flow to earth all the time a storm is overhead, instead of the single high-intensity discharge a rod has to survive.

Where it is used

• Flare stacks and burners in refineries and petrochemical plants
• Chimneys and stacks in steel, cement and power plants
• Boilers, furnaces and process-heat equipment
• Any structure exposed to high temperature or flame emission

DDCE compared with a conventional lightning rod or ESE arrester

• Prevents lightning strikes on the structure — a conventional rod or ESE arrester attracts them.
• Continuously compensates the changing electric field — a rod only acts at the instant of the strike.
• Reduces electrification, corona effect and electromagnetic pulses in the protected structure — an attracted strike increases them.
• Generates a controlled, low-intensity leakage current — an attracted strike sends a dangerous, high-intensity current down the conductors.

Proven in the field

• Telecom operator field trial, Indonesia — with a 34% lightning-fault rate across its sites, the operator installed more than 200 units each of three technologies and compared them after one year: DDCE sites went to 0% faults, a dissipation-array (DAS) system reached 26%, and active (priming/ESE) rods rose to 36%. (Dinnteco published case study.)
• Endesa (Enel) substation near Barcelona, on a hill locally nicknamed "the lightning hill" — no direct strikes on the substation after one DDCE was fitted to an HV tower; Enel then protected four HV towers on a line north of the city. (Dinnteco published case study.)
• Chikyu, described by Dinnteco as the largest oceanographic vessel in the world (JAMSTEC, Japan) — no incidents reported since a DDCE was installed at its highest point. (Dinnteco published case study.)
• Ushiku Daibutsu (Japan) — a DDCE 100plus protects the statue and the telecom equipment at its top after an earlier strike brought down a 5 m piece of the Buddha's hair; no recorded strikes since. (Dinnteco case study and catalogue.)
• Petrochemical plant, Texas (USA) — DDCE 100plus, 50plus and air installed in 2023: 0 recorded strikes. (Dinnteco catalogue.)
• Telecom site, Bilbao (Spain) — DDCE 100plus installed in 2016: 0 recorded strikes. (Dinnteco catalogue.)

Which Dinnteco device do I need?

• DDCE 100plus — flagship, up to 120 m radius, 7 kg: large and critical structures.
• DDCE UL96 — the same 120 m class where a project needs UL 96 listing.
• DDCE 50plus — protection radius up to 60 m, 5 kg: for structures up to 20 m tall, side or complementary protection.
• DDCE 25plus — protection radius up to 30 m, 2.7 kg: for small structures up to 7 m tall.
• DDCE air — 0.8 kg for streetlights, lighting towers and masts up to 10 m tall.
• DDCE magma — stainless steel and alumina for burners, flares and hot structures.
• dinland — no visible device, for heritage and landscape-sensitive buildings.

Frequently asked questions

Why a special DDCE for high temperatures?

Standard DDCE devices are aluminium/POM. The magma uses stainless steel and alumina so it keeps working on structures exposed to very high temperatures.

Can it be mounted directly in a flame?

No. It is designed for structures exposed to high temperatures and flame emission, but Dinnteco specifies it must always avoid direct flame.

Which industries use the DDCE magma?

Oil, gas and petrochemical plants, steel and cement plants, power plants and any site with burners, flares or hot stacks.

How much does it weigh?

8.9 kg.

What warranty does it carry?

5 years from Dinnteco.
