Positive Isolation for Fertilizer: Enhance Your Plant Efficiency
ONIS provides custom-designed products to safely isolate your piping equipment, including pumps, compressors, reactors, and all other hazardous areas in fertilizer plants, thereby facilitating the production of key chemicals such as ammonia, urea, and nitric acid.
The Challenges of Fertilizer Plant Operations
Fertilizer plants require careful management of hazardous materials, such as ammonia, urea, and nitric acid. Traditional pipe isolation methods, like spectacle blinds and figure 8s, can be time-consuming, labor-intensive, and pose a risk of leakage, compromising operator safety and plant productivity.
Boost Your Fertilizer Production with ONIS
Reduce Downtime
Isolate piping areas within minutes, minimizing production losses and increasing overall plant efficiency.
Improve Safety
Prevent the possibility of process media leakage to the isolated area, ensuring a safer working environment for operators.
Eliminate Tools
No tools are required for operation, reducing the risk of human error and increasing productivity.
Equipment Specifically Design For Your Application
ONIS solutions are designed to meet the challenges of demanding industrial environments in fertilizer plants. We put our expertise at the service of customization, guaranteeing optimum chemical compatibility. Our range of materials includes stainless steel, carbon steel and specific corrosion-resistant alloys, as well as high-performance coatings such as PFA and PTFE. To meet the specific needs of each application, we also offer adapted seals (elastomers, graphite, etc.) to guarantee optimum performance.
Quick Action Line Blind
Our Quick Action Line Blind offers a fast, advanced alternative to traditional spectacle blinds. It enables fast, tool-free positive isolation, guaranteeing the safety of hazardous substances while ensuring an unrivaled level of reliability thanks to our patented design.

Block Bleed & Blind
