FoamWorks are a distributor of Graco's industry leading line of Reactor proportioners. There are many models to choose from based on application, heater capacity, flow rates and more. Some Graco proportioners are specifically designed to spray polyurethane or Icynene foam, while others are suited for high pressure applications like polyurea coatings.

All Reactor proportioners or metering units are designed to mix two components at a certain ratio, which is usually but not always 1:1. Proportioners provide three main functions: keeping the desired ratio of the two materials being processed, maintaining a certain, very high pressure, and heating the materials to a certain temperature. Modern polyurethane, polyurea or hybrid systems perform best within narrowly defined ratios. Our proportioners achieve variances of less than 1% if the temperatures and resulting viscosity are on target. The high pressures provide optimal mixing inside the spray gun. Current technology makes it almost impossible to make bad foam or coatings by having incorporated computer controls which maintain ratio, pressures and temperatures or which stop the proportioner should there be a malfunction.

FEATURES

High-Output Hydraulic Proportioner for Spray Foam or Polyurea

Graco’s high-output H-40, and its high-pressure sibling H-XP3, are the industry flagships. Graco has managed to create an ultra-reliable system which combines the classical horizontal Gusmer pump line with Graco’s computer-supported controls and engineering quality. Extremely robust yet simple pump design keeps downtime to an absolute minimum, while generating profits for its owner. A long list of features, including pressure gauges that monitor transfer pump performance, help the foam installer maintain peak productivity even in cold weather applications.

• Maximum output of 45 lb/min (20 kg/min) in foam configurations
• Choice of maximum pressures between 2000 psi (138 bar, 13.8 MPa) and 3500 psi (240 bar, 24.0 MPa)
• Supports up to 410 ft. of Graco heated hose
• Various hybrid heater designs of up to 20.4 kW provide extreme heating power
• Advanced diagnostics
• Analog gauges for incoming material pressure and temperature
• New electronic design with separate boards for motor, and all three heater zones
• Many ratios besides 1:1 available. Ratio can be changed in the field.
• Upgrade to Reactor-IP (in-plant) system available with timed shot sequences and more
• The applicator can set pressure imbalance breakpoint at which system shuts down
• Gun crossovers are almost a thing of the past, since the system shuts down in case of ratio imbalance

TECHNICAL 

The Graco H-40 has revolutionized the world of Spray Polyurethane Foam with its technical advances and breakthroughs

1. New lightweight hydraulics are only a fraction of the weight of standard hydraulic units
2. Circulation valves – redesigned to prevent failures associated with isocyanate crystallization
3. Horizontal pump design provides smoother performance, extends seal life by 10 times, essentially eliminates pump leaks, and simplifies maintenance by using common parts
4. Easy troubleshooting of transfer pumps: analog temperature and pressure gauges are standard
5. Electronic platform simplifies troubleshooting and greatly reduces downtime

APPLICATIONS

Setting new standards in the spray foam industry, the H-40 is one of the most versatile machines today.

Generally speaking, the H-40 or the H-XP3 should be chosen for applications requiring high output, high heat capacity such as in cold/very cold climates, or high uptime. While this system requires a little more initial investment than a smaller system, the return on investment is very high for a number of reasons including its legendary uptime and long life expectancy. Previous models have lasted more than 10 and often up to 20 years.

Foam Roofing

No matter how large or small the roof, the Graco proportioner H-40 will produce the foam needed to finish the job on time. This machine can easily yield 10,000 to 15,000 lbs. of foam in a single shift as long as your crew can keep up.

Spray Foam Insulation

This machine is right for high output, large scale residential or commercial spray foam insulation. Especially in large commercial applications, the H-40 foam system will cut production time significantly.

In-plant OEM

This metering unit is well suited for refrigerators, cold storage panels and similar injection work. This system is also available as an upgraded version IPH-40, which supports timed shots in combination with the AR-D and other guns.

Polyurea and other Coatings

These applications are best executed using the H-XP3, especially in case of larger job sizes. All of the listed coatings perform best when applied using high heat and high pressure. The massive pre-heaters generate over 20 kW while the static pressure can reach 3500 psi. The finished product will reflect this.
