Compressor season is coming

Dry and alternate fire sprinkler systems play a vital role in fire protection, particularly in regions where freezing temperatures are a concern – for us, the UK is a major market.

Dry and alternate systems rely on compressors to maintain the integrity of pipes and sprinkler heads during the harsh winter months, as they prevent freezing and ensure that the system functions flawlessly when it’s needed most. The primary purpose of compressors in dry systems is to maintain air pressure within the pipes, displacing the water inside which may otherwise freeze. When a sprinkler head is activated, the air pressure drops, allowing the valve to open and release the water.

To ensure the reliability of compressors in dry fire sprinkler systems over winter, regular maintenance is essential – including inspection and testing compressors, checking for leaks, and verifying that all components are functioning correctly. Maintenance (including the switch over from wet to dry, for alternate systems) should be conducted before the onset of winter to address any potential issues and guarantee that the system is ready for freezing temperatures.

In systems with a higher risk of freezing, air dryers may also be used, and any desiccant and oil removal filters should be checked and – if necessary – replaced.

In conclusion, compressors may be the backbone of dry fire sprinkler systems, especially in winter, ensuring that these life-saving systems are ready to respond to fires at any time. Regular maintenance, air pressure monitoring, and backup power sources (in remote areas) are key elements in keeping compressors and dry fire sprinkler systems reliable throughout the winter, providing peace of mind for property owners and occupants alike.

Here at SEP, we are renowned for our range and quality of air compressors, and early winter (when alternate systems are switched over) we become incredibly busy with compressors, which is why we spend summer and autumn stocking up as much as possible. We’re here when you need us for any planned maintenance, replacement or breakdowns.

As many will know, our range has been overhauled in recent years with new models of pump now being used for our wall-mounted range (SEP1.5S, SEP1.8S, SEP1.8T), and in addition we have our newer range of oil-free ultra-quiet models (SEP0.7S.OFQ, SEP1.5S.OFQ), plus a new mid-range SEP2.2S unit before you hit the large belt-driven machines.
