Drum heaters are used to keep products warm in cold enviroments. They are also used to pre-warm chemicals to the manufacturer's recommendations.
Example: With some open-cell spray foams, chemical manufacturers recommend that the drum temperatures be between 70 to 90 + degrees before the product is pumped to the spray foam machine. Typically, closed-cell spray foam drums are maintained between 70 to 80 degrees.
The spray foam machine is where the manufacturing of spray foam begins. The materials are pumped from the (A) and (B) 55 gallon drums by the transfer pumps to the Y filters (screens) on the machine to pre-filter any contaimants from the drums. From the Y- Filters, the materials are pressurized by two pumps at 1,000 to 1,500 PSI. One pump for the (A) component and one pump for the (B) component, attached to a single-drive system. (PMC hydraulic spray foam machine shown in photo). Once the chemicals are pressurized, they enter the pre-heaters. The pre-heaters are designed to pre-warm the products to the manufacturer's processing recommendations ranging from 120 degrees to 140 degrees. The materials exits the pre-heaters, passing through two pressure gauges, allowing a user to monitor the materials being processed at a 1:1 ratio. The gauges are also used to trouble-shoot the spray foam machine. From the guages, the materials enter into the heated spray hoses.
Heated spray hoses are designed to maintain the manufacturer's pre-heated recomendations from the machine to the spray gun. Heated spray hoses are typically sold in 50ft sections. The end of the hoses has a 10ft heated whip hose used for flexibilty for the spay applicator. Pending the spray foam machine choosen depends on how many feet of heated hose is available to run from the machine to the spray gun. Spray foam machines vary in heated hose lengths with capibilties ranging from 210ft to 410ft.
The spray gun is the final destintion as to how a spray foam rig works and the spray foam manufacturing process.
The two (A) and (B) chemicals are blended inside of the spray gun through the internal mixing chamber. Mixing chambers are designed for optional output flows, allowing the user to choose the flow of material as well as the production needed for the spray foam project.
