Proportioners

Proportioners

At the heart of your foam insulation or coating business is the proportioner.

This machine heats and pressurizes the materials at recommended ratios, temperatures and pressure to create a chemical reaction, creating the foam or coating. Proportioners come in a variety of pump styles and outputs depending on volumes required for specific applications.

Graco’s Reactor line of spray equipment are state-of-the-art proportioning systems that gives superior performance, control and accuracy. They are designed to apply polyurea, foam and other fast-set materials that require accurate temperatures and pressures necessary to achieve ultimate results.

Which system is right for you?

Graco Reactor proportioners are available with air, electric or hydraulic pumps. All Graco Reactors carrying the “XP” designation in the model name are capable of processing 1:1 ratio foam insulation along with protective coatings. Each system has its own unique benefits:
