The Technology - Gas Pressurized Systems**
Corrosion in fire sprinkler systems is widespread, costly and disruptive.
Now thanks to Holtec’s pioneering work, the cost and operational downtime associated with replacing corroded sprinkler piping can be avoided. With patented and patent-pending innovations in this field, we are at the frontlines of the rapidly growing application of using nitrogen gas in pressurized sprinkler systems – virtually eliminating corrosion in new piping systems and allowing the use of less costly materials during construction. Generated nitrogen gas is the effective and environmentally friendly way of treating this costly problem, and available leasing allows for rapid implementation of the technology.
The Problem: Leaks resulting from Corrosion
The oxygen content of moist compressed air is by far the main cause of internal corrosion in steel and galvanized steel forming gas pressurized sprinkler piping. Microbial Induced Corrosion (MIC) is relatively of minor importance.
The Solution: Holtec’s Nitrogen Inerting Technology
Using dry, inert, and non-corrosive nitrogen gas produced from one of our family of compact nitrogen generators in place of compressed air virtually arrests corrosion. Holtec supplied the first nitrogen generator in the US for protecting gas pressurized sprinkler piping from corrosion in mid-2006. Since that time Holtec developed and perfected the use of nitrogen generators specifically tailored to supply inert nitrogen gas corrosion protection to gas pressurized fire sprinkler systems. More than 250 Holtec nitrogen generators have been installed in the U.S., Canada, and Europe; protecting more than 50,000 feet of piping and more than 5 million square feet of floor area. Holtec’s expertise in the generation and use of nitrogen gas is the accepted standard for solving this problem . Our generators produce nitrogen with only 1% of damaging residual oxygen compared to double that amount (2%), in the nitrogen from competitors’ generators.
Information needed for a quotation from Holtec:
In order to be able to quickly evaluate the application of nitrogen for gas pressurized sprinkler systems Holtec needs the following initial information. All of this is on our inquiry form but here is a little more explanation why the information is required:
Always exercise caution using these systems in occupied areas as nitrogen in the absence of oxygen does not support life. We have created a simple computer calculation method to determine if an occupied space is sufficiently large to be safely protected by a sprinkler system pressurized with nitrogen gas, taking into account the volume in the sprinkler piping, the operating pressure and the elevation at the location. Holtec is making this available to all. Please contact us for your copy of this important tool.
