Keep kitchen exhaust grease off the roof with the Grease Box Jr. Grease Containment System. The Grease Box Jr is manufactured from 24 gauge galvanized sheet metal. All parts are cut from sheet metal and bent and shaped into their proper form. Most metal to metal attachments are spot welded. The only components not constructed from sheet metal are the piano hinge, the door latch, the perforated metal base and the Polypropylene Pillows.
Low Volume & Low Clearance
2 Tiers with one of a kind patented Polypropylene Grease absorbent pillows
- The 1st Tier has the patented Even Water Flow Diverter
- The 2nd Tier has the patented Over Flow Walls
Installation is easy too! 3 self tapping metal screws and 2 minutes. No cutting! No Bending! No Caulking! No Rods! No Bolts! It does not get any easier!
How It Works:
The Original, Jr., and X-treme systems all work on the same grease capturing theory. The first and second steps are very similar as to the way the grease is allowed to flow through the polypropylene pillows. Polypropylene is a hydrophobic material that will only absorb the grease running through the system. The only major difference between the systems are the capacity of grease they are able to absorb.
The third level in the Original, and X-Treme system is a simple over flow tray that also have our patented pillows placed inside.
The trick to the Grease Box products being so effective is simple. By allowing a time transfer from a high flow volume entering the system to the slower low volume leaving the system. These designs slow the water and F.O.G. flow to a ratio that the pillows can have time to absorb the grease running through the system.
Friction points through out the entire system allow for points where there is friction to agitate the grease and water that is running through.
Grease will solidify at a temperature of anything over 50 degrees . (This is only an estimate and will very dependant on the type of grease as well.) The metal these systems are made out allow the temperature of the box to stay cooler in the sun than most traditional open drain field systems that have direct UV exposure.
The unique design of these systems have allowed for a low impact onto the exhaust system and for them to blend with the ductwork so they are not an eye soar.
The Grease Box Systems are a gravity fed system. What this means is that they are designed for flow to enter in the top and exit in the bottom. The weight you will feel in the system when it is time to service will be from the grease in the pillows. No water!
