Rob, our MD, was privileged to be able to attend the European Fire Sprinkler Network’s (EFSN) Fire Sprinkler International conference and exhibition in Paris (very handy, as he’s a big fan of France!), on 22/23 April – the event broke all previous records, being attended by over 600 fire sprinkler industry representatives from across the globe… UK and France, obviously, …
NEW SEP Compressor
After more than a year of research, design and development, SEP introduces the first, and only, floor-standing compact oil-free super-quiet compressor designed specifically for the fire sprinkler market. Using our extremely popular and trusty SEP0.7S motor/pump, along with our renowned top-quality trim and electrics, we are sure this is going to be a winner. Why? On every measure, our SEP0.7S.FR (Floor-mount Receiver) is …
SEP Recycling
Something we have been offering for some years now, but many customers are unaware of, is the option that you or your clients have to return any ‘end-of-life’ SEP products (or any other products we have supplied) for recycling. We will then disassemble, segregate and recycle all recyclable materials through our own waste carriers, and safely dispose of anything else …
Why is ZG Orientation critical?
One of the things we discuss heavily at our training sessions – and often with customers out in the field – is the importance of orientation when installing Zone Guardian (or Zonecheck, for that matter!). If installing on a vertical riser, you don’t need to read on! As you can see from our graphic above, the ZG is built with the flow switch and …
New SEP compressor…
…coming soon! As most of our commercial sprinkler customers will know, we are renowned for our top-quality air compressors designed and built specifically for dry, alternate and pre-action fire sprinkler systems. In fact, when our MD first arrived back in 2014, it seems that most of customers considered us as ‘the compressor company’ (although we’ve come a long way since …
“Normally Open/Closed” – eh?
Here at SEP, we sell a lot of specialist valves, and something which seems to cause most confusion is in relation to solenoid/automatic/actuated valves and the meaning of ‘normally open‘ or ‘normally closed‘. You may also hear the same terms being used in relation to switches, electrical circuits, alarm panels, pressure or flow switches etc – and although principle is …
Need Dry Air?
It’s far from unusual in the northern hemisphere for fire sprinkler systems to be dry (either all the time, or only during winter months, or maybe only part of the system) – and this is one of the reasons why our exclusive range of UK-manufactured air compressors is one of our biggest lines. Such systems can include warehouses, loading bays, …
SEP Training continues in 2026
We at SEP were excited and honoured to host another group of delegates from J&J Fire Engineering on 18th February for one of our free training sessions. The team from J&J comprised a great mix of people – young/older, new/established, designers/service team/projects, local and three who made a big effort to attend from London… and including a female trainee Project Manager …
Gauge Certification
Calibrated/certificated pressure gauges play a pivotal role across numerous industries, providing precise measurements critical for safety and quality assurance. They are intended to accurately measure, against traceable standards, the fluid pressure within a system, ensuring performance and mitigating potential risks. In a fire sprinkler, dry- or wet-riser system, the main purposes are to ensure the system pressure is known and accurate …
Stop mains-fed false alarms
Although mains-fed commercial sprinkler systems are far from the most common type, false alarms are a real pain – certainly for your client, but also for you as the maintainer! If these False alarms are due to pressure fluctuations, then we can help – we have a device which will help prevent them completely. You need a SEP Alarm Valve Booster Pump! SEP designed this …
