Defining a New Standard in
Low Pressure Spray Foam Equipment



The Nitrosys Spray Foam System is a new low-pressure spray foam system that takes the guesswork out of processing low-pressure polyurethane foams.  With auto calibration and material pre heaters, the Nitrosys set  a new standard in the low-pressure spray foam equipment market.  Eliminate material wastes, save on labor costs, and increase production with an easy to use spray foam proportioner designed to make spraying foam as easy as 1, 2, and 3!

ProPAK Nitrosys defines a new level of spray rig technology by introducing a full mobile spray rig into the low-pressure spray market.  This unit is fully turnkey with everything you need to operate a successful low-pressure  spray foam job. Nitrosys Low Pressure Spray Foam System.

Increase Material Yield With New Low-Pressure System

GREENSBORO, GA–November 9, 2015–The days of endless calibrations and squandered material yield are over. (SFS) is proud to announce its latest innovation in the low-pressure SPF market, the NiTROSYS low-pressure foam system. NiTROSYS is a proportioner for refillable low-pressure SPF systems.

“The NiTROSYS system automatically pre-heats and then calibrates the material to the exact proper ratio while keeping the material at the ideal temperature through the length of the hose in order to produce the highest quality foam,” said T.J. Peters, General Manager of SFS. “If you look at the low-pressure market, there really isn’t equipment out there used for processing the refillable foam systems.”

From crawlspaces to touch-ups to whole-house weatherization, low-pressure spray foam is a cost-effective solution for numerous smaller-scale applications. However, low-pressure foam contractors are faced with the time-consuming and often inaccurate task of calibrating their low-pressure systems. Even worse, the calibration process involves extensive test spraying and re-calibration, resulting in wasted material and overall diminished yield.

“I’ve met with a lot of people over the years who used refill systems and basically abandoned them because of the complexities of calibrating the material,” said Peters. “NiTROSYS eliminates contractors out on the job site manually calibrating their material.”

SFS estimates that NiTROSYS can deliver at least a 10% increase in yield versus applying low-pressure foam the standard way. In terms of material and labor costs, NiTROSYS can offer contractors immediate savings in operating expenses for low-pressure applications. In fact, SFS offers an online tool that contractors can use to calculate their calibration costs and yield improvements with NiTROSYS.

What makes NiTROSYS capable of this kind of performance? It’s designed to give contractors more control over refillable low-pressure foam systems. NiTROSYS preheats the material and calibrates it by volume, so it never needs recalibration on the job site.

“The system is powered by nitrogen, so there is no air compressor needed, which is a big plus,” said Peters. “It has a heated hose built in, so it maintains temperature all the way to the gun.”

NiTROSYS also features a stroke counter, which saves contractors from the inaccurate method of determining yield via weighing material.

Additionally, NiTROSYS offers safety benefits versus high-pressure SPF applications, most notably with shorter reentry times and the ability to use full-face respirators rather than supplied-air respirators.
