Minimax Spark Extinguishing Systems for Pneumatic Conveying
Description
Stopping sparks before they become flames in conveying lines
Minimax spark extinguishing systems detect ignition sources in suction and conveying systems and use an automatic extinguishing device to create a water spray curtain across the whole pipe cross section. They are used wherever combustible materials are conveyed pneumatically, for example in the wood, textile and food industries, where sparks or hot particles can cause fires or dust explosions.
Normally the suppression takes place without stopping production, which avoids costly machine downtime. Minimax states it has over 50 years of research behind the technology and offers systems with VdS and FM approval that have been used in many thousands of applications worldwide.
Technical specifications
| Parameter | Specification |
|---|---|
| Standard system | Spark detectors, control panel, automatic extinguishing device with water supply |
| Spark detector | UniVario YMX5000, reacting to infrared radiation of passing ignition sources; functional monitoring of electronics and optics; fiber optic version for elevated temperatures |
| Control panel | FMZ6000 with reflex module; meets EN 54 parts 2 and 4 and EN 12094-1; VdS and FM approval stated |
| Spark counters | Three counters per spark detector line, one averaging over a definable period |
| Event log | Spark messages and start and end of extinguishing recorded accurate to the millisecond |
| Extinguishing device | Quick release solenoid valve, patented self-closing flat spray nozzle F180, valve unit G1 |
| Nozzle coverage | 180 degree protected zone with a single F180 nozzle |
| Water supply | Pressure booster pump unit with diaphragm pressure tank, control devices and centrifugal pump |
| Monitoring | Cable connections monitored for wire break and short circuit; flow monitoring in the extinguishing device; ball valve position can be monitored electrically |
| Mounting | Quick assembly kits for sensors and nozzles on conveyor pipes and drop shafts |
Operating sequence and design details
When a spark detector sees a spark or hot particle, it signals the control panel, which opens the solenoid valve of the extinguishing device within milliseconds and releases a dosed amount of water. The glowing particles fly into the water curtain from the nozzle and are extinguished, and the valve closes again at once. Alerting is activated at the same time, and depending on the number of ignition sources an automatic machine shut-off can follow.
The F180 flat spray nozzle covers the whole pipe cross section with minimal water use, whereas conventional disk nozzles often need several nozzles or longer straight pipe after the nozzle. A pressure booster pump unit is required if the plant uses a sprinkler system with pressure tank or a water network that does not deliver the minimum pressure. If the pump fails, several extinguishing blasts remain available from the diaphragm tank. Quick assembly kits also give quick access to sensors and nozzles for cleaning.
The detectors are UniVario YMX5000 units, and the panel can be the Minimax Clunid FMZ6000.
What to confirm before ordering
A quotation needs the number of conveyor or drop-shaft lines, pipe diameters, conveyed material, temperatures at the detector position, available water pressure and flow, and the control panel in use.
Documents and quotation
The Minimax brochure AL06e (print run 04.23) is attached with the component diagrams. Seven Star LLC is an independent supplier in Muscat; scope and components are confirmed with Minimax before a quotation. See Fire Fighting for related products.

About brand
Fire detection and extinguishing systems for industrial plants, data centers and logistics buildings are the business of Minimax, based in Bad Oldesloe, Germany. Seven Star LLC is an independent supplier in Oman and lists Minimax fire control panels, detectors, a deluge valve set and the MxSysCon fire control configuration software, supplied with its licence dongle. We also take inquiries for Minimax fire protection components and spare parts identified by part number.
Minimax systems the software and parts belong to
The manufacturer's program covers fire detection and extinguishing control panels of the FMZ family and HELIOS aspirating smoke detectors. On the extinguishing side it builds deluge and other water-based systems, Minifog water mist, Oxeo inert gas and carbon dioxide systems, and spark extinguishing. Panel configuration software is tied to a specific panel generation. We did not find the name MxSysCon in the manufacturer's public documents, so the software version has to be checked against your panel type.
Ordering Minimax items: what we need
Send the Minimax part number, the type and firmware version of the control panel, and a photo of the panel label. For detectors, nozzles or valves, add the nameplate data and the approval the project specifies. Minimax systems are engineered per site, so a component is only correct when it matches the original system documents. We check that match for buyers across the GCC before the order is placed.

Frequently Asked Questions
What does a standard spark extinguishing system consist of?
Spark detectors, a control panel and an automatic extinguishing device with the corresponding water supply.
How fast does it react?
The control panel activates the solenoid valve of the extinguishing device within milliseconds of a spark message.
Does production have to stop?
Normally not, because suppression takes place during production, although an automatic machine shut-off can follow a high spark count.
Why use the F180 flat spray nozzle?
It creates a uniform water curtain across the entire pipe cross section with minimal water use, often with a single nozzle.
Which approvals does Minimax state?
The brochure states that its spark extinguishing systems have VdS and FM approval.
