Introduction to "Frozen Method" for Plumbing Work in Firefighting Equipment Renewal!

Introduction to "Frozen Method" for Plumbing Work in Firefighting Equipment Renewal!

Firefighting equipment can be replaced with minimal water drainage! More people are utilizing the "freeze method" during the replacement of the deluge valves due to the revised inspection standards for foam firefighting equipment.

The "freezing method (for buildings)" is a technique that uses liquid air (nitrogen) to freeze the water in pipes, allowing for the replacement of pipe branches and valves, as well as expansion work, with minimal water drainage. The frozen section acts as a stop valve, enabling plumbing work to be carried out without shutting off the water supply to the entire building. Recently, due to the revision of inspection standards for foam fire extinguishing systems, more companies are utilizing this method when replacing open valves. It can also reduce construction time and the cost of chemical disposal, so if you are interested, please feel free to consult with us. 【Features】 ■ Minimal water drainage - Possible to replace even with integrated valves - Reduced construction time ■ Foam extinguishing is also okay with freezing! - Numerous construction achievements using foam extinguishing agents - Reduced chemical and disposal costs ■ Water pressure resistance up to 1.4 MPa *For more details, please refer to the PDF materials or feel free to contact us.
