The PH(X)-55 Proportioner is a custom-built, hydraulic, heated, plural component proportioner designed for professional use in spraying polyurethane foam and coatings. It is not approved for use in explosive atmosphere locations.

Function Description:

The PH(X)-55 Proportioner is engineered to accurately mix and dispense two-component chemical systems, specifically polyurea, polyurethane foam, and some two-component epoxy systems. Its hydraulic drive system ensures consistent pressure and flow rates, crucial for high-quality application of these materials. The heating capabilities maintain optimal material temperatures, which is essential for proper chemical reaction and spray pattern. The "plural component" aspect means it handles two separate chemical components (typically an "A" side and a "B" side) and mixes them at the point of application, preventing premature curing within the machine.

Usage Features:

The PH(X)-55 Proportioner is designed for ease of operation, though it requires careful adherence to safety protocols. The console features controls for managing the spraying process, including temperature controllers. The machine's robust design allows for efficient application of materials, ensuring consistent output and quality. Users are advised to thoroughly read the technical and safety documentation to understand the operation and conditions of use, which aims to improve user safety and prevent breakdowns. The design and configuration explicitly state that it is not for use in potentially explosive atmospheres, and pressure/temperature limits must not be exceeded.

Safety and Handling:

The manual stresses the importance of safety with clear warnings and cautions:

WARNING! Highlights information that could cause serious injuries if instructions are not followed.
CAUTION! Indicates how to avoid damage to the proportioner or minor injuries.
NOTE! Provides relevant procedural information.
Operators must wear suitable personal protective equipment (gloves, goggles, safety footwear, face masks, breathing equipment in enclosed spaces).
Always use compatible liquids and solvents.
Read Material Safety Data Sheets (MSDS) for raw materials and solvents.
Do not open pressurized connections or perform maintenance until pressure is completely eliminated.
Avoid touching hot components until they have cooled.
Ensure all safety guards are installed on moving parts before operation.

The PH(X)-55 Proportioner is a sophisticated piece of equipment requiring diligent operation and maintenance to ensure safety and optimal performance in plural component spraying applications.
