ANSUL JET-X 2 3/4% High-Expansion Foam Concentrate Drum - 420009

ANSUL JET-X 2 3/4% High-Expansion Foam Concentrate Drum - 420009

JET-X 2 3/4% High-Expansion Foam Concentrate contains hydrocarbon surfactants, solvents, and stabilizers is formulated for use with medium- and high-expansion foam generators. This synthetic foam concentrate is intended for firefighting applications at 2 3/4% solution in fresh, salt, or hard water. JET-X 2 3/4% foam solution can be used to produce foam with expansion ratios ranging from 50:1 to 1000:1 depending upon the type of generator and its operating pressure. The foam blanket has excellent mobility and stability and utilizes several suppression mechanisms:

• Free air movement necessary for combustion is reduced.
• The temperature is cooled below the combustion or auto ignition temperature and oxygen is displaced as liquid drains from the foam and converts to steam.
• The reduced surface tension of the liquid draining from the foam penetrates into Class A materials.
• Insulating and heat reflective properties provide a heat shield and block radiant heat feedback.

Application

JET-X 2 3/4% High-Expansion Foam Concentrate is a tremendously flexible firefighting agent, used in suppressing Class A, Class B, and LNG fires both indoors and outdoors. The foam solution should only be used with air-aspirating foam discharge devices except when used as a wetting agent on Class A fuels. JET-X 2 3/4% Concentrate, when used with high-expansion generators, is capable of totally flooding large rooms and enclosures allowing it to effectively suppress horizontal and vertical (three-dimensional) fires. High-expansion foam is also effective in reducing vapor concentrations downwind from unignited LNG and other hazardous low boiling point gaseous products such as ammonia spills. When used with medium-expansion foam equipment, JET-X 2 3/4% Concentrate forms a foam blanket which prevents the release of fuel vapor and provides additional cooling due to the higher water content. Medium-expansion foam has benefits in outdoor applications because the foam is less affected by wind conditions.

Approvals, Listings, and Standards

JET-X 2 3/4% High-Expansion Foam Concentrate is designed in accordance with National Fire Protection Association (NFPA) Standard 11 for Low-, Medium-, and High-Expansion foam. The concentrate is approved, listed, qualified under, or meets the requirements of the following specifications and standards:

• UL Standard 139, High-Expansion Foam Liquid Concentrates

Foaming Properties

The performance of JET-X 2 3/4% High-Expansion FoamConcentrate will vary depending upon the performance characteristics of the equipment. Expansion ratios through highexpansion generators are typically between 200:1 and 1000:1. For this reason, it is important for the proper design of a highexpansion system that the JET-X 2 3/4% High-Expansion Foam Concentrate be specifically listed with the foam generators. Refer to the performance table listing expansion ratios of JET-X high-expansion generators used in conjunction with JET-X 2 3/4% Foam Concentrate (see data sheet JET-X High-Expansion Foam Generator, Form No. F-93137, latest revision). Mediumexpansion foam generators typically deliver expansion ratios between 50:1 and 200:1.

Proportioning

The recommended operational temperature range for JET-X 2 3/4% High-Expansion Foam Concentrate is 35 °F to 120 °F (2 °C to 49 °C) per UL 139. This foam concentrate can be correctly proportioned using most conventional, properly calibrated, in-line proportioning equipment such as:

• Balanced and in-line balanced pressure pump proportioners.
• Balanced pressure bladder tank proportioners
• Around the pump type proportioners
• Fixed or portable in-line venturi (eductor) type proportioners
