They worked closely with Fronius in achieving this listing as it required the development of an additional capacitance bleed circuit to dispel stored current upon Rapid Shutdown initiation. That product has also been certified as a PVRSE (Photovoltaic Rapid Shutdown Equipment) component by UL for use in the categories needed. These new listings supplement IMO's current UL listed FireRaptor offering for NEC 2017 & NEC 2020 compliance, thus further encompassing a complete agnostic solution for all inverters in the marketplace.
Speaking from IMO Automation's HQ in Cumming GA, General Manager Joe Covington said "Supporting efforts and inverter manufacturers in the market is key to enabling the continued growth of the industry when faced with progressive NEC regulatory requirements. It is those partnerships and the comfort they have in approaching IMO for a safe and reliable Rapid Shutdown solution that sets us apart from the competition.".
The FireRaptor is designed to be installed at solar panel level and provides safety shutdown of the DC supply to ZERO volts in case of emergency. Shutdown is initiated in 3 ways - Manual Operation by way of an emergency shutdown switch (which can be conveniently located at ground level for easy access), AC Supply Cut-Off, or a Temperature Rise Trigger.
The FireRaptor operates in the same way as a disconnect switch, making the FireRaptor compatible with all string inverters, and does not affect their operation or performance in any way. Additionally, the FireRaptor has been designed for fail-safe operation ensuring that once operated, subsequent damage to the FireRaptor (e.g. by fire) will not compromise the solar panel isolation and shutdown status. Indeed, the FireRaptor has been tested to destruction by TUV in Germany, maintaining full zero volt isolation throughout the test procedure.

Vecoplan - Planning and implementation of complete processing plants in refuse derived fuel production
In order to reduce the costs involved in the energy-intensive production of cement, many manufacturers are turning to refuse-derived fuels (RDF), considerably reducing the proportion of expensive primary fuels they would normally use. Solid fuels are being increasingly used - these might be used tyres, waste wood or mixtures of plastics, paper, composite materials and textiles. Vecoplan provides operators of cement plants with proven and robust components for conveying the material and separating iron and impurities, efficient receiving stations, storage systems and, of course, efficient shredders for an output in various qualities.
