What is a Mobile Foam Unit? IS 15105 & NFPA 11 Guide

What is a Mobile Foam Unit? IS 15105 and NFPA 11 Standards Governing Foam Unit Specification

A mobile foam unit is a portable firefighting system designed for rapid deployment to extinguish flammable liquid fires in industrial settings like refineries, chemical plants, and storage terminals. These self-contained units integrate foam proportioners, tanks, pumps, and monitors, enabling on-site foam generation compliant with global standards. As an ISO 9001:2015 certified manufacturer from Naroda, Ahmedabad, Gujarat, India, with 15+ years experience, 1000+ projects, and exports to 26+ countries, Kinde Fire ensures our mobile foam units meet IS 15105 and NFPA 11 requirements for superior fire suppression performance. This guide details key specifications for international buyers and project managers sourcing reliable equipment.

Overview of Mobile Foam Units Under IS 15105 and NFPA 11

Mobile foam units are critical for Class B fire suppression, providing mobility for high-risk areas. IS 15105, the Indian standard for mobile foam units, aligns with international benchmarks like NFPA 11, ensuring interoperability for export projects.

Definition and Scope of IS 15105

IS 15105 specifies trailer-mounted or skid-based units with minimum 500-liter foam tanks, suitable for hydrocarbon fires up to 10,000 sqm. It mandates BIS certification for quality assurance.

NFPA 11 Fundamentals for Mobile Systems

NFPA 11 outlines low-, medium-, and high-expansion foam systems, emphasizing mobile units for emergency response with discharge devices covering 30m radii.

Harmonization for International Buyers

Both standards require corrosion-resistant materials and automatic proportioning, ideal for Kinde Fire’s exports to 26+ countries. Read our complete guide on What is a Mobile Foam Unit?

Key Foam Application Rate Requirements

**What is a mobile foam unit**’s effectiveness hinges on precise application rates defined by IS 15105 and NFPA 11, ensuring blanketing of fuel surfaces without breakthrough.

Minimum Rates per IS 15105

For polar solvents, rates start at 6.5 lpm/sqm; non-polar at 4.1 lpm/sqm for 55 minutes on 14.6 sqm test fires, per BIS testing.

NFPA 11 Expansion Ratios and Rates

Low-expansion foam requires 0.16 gpm/sqft (10.6 lpm/sqm) for hydrocarbons, scaling to 0.26 gpm/sqft for alcohols, with mobile units delivering 500-2000 lpm.

Practical Implications for Industrial Deployment

Kinde Fire units achieve 4.1-11.1 lpm/sqm, certified under IS 15105, supporting OISD guidelines for oil installations. Internal link: Explore Kinde Fire Mobile Foam Equipment.

Foam Types and Compatibility Standards

Standards govern foam concentrates to match fuel types, with mobile units proportioning 3-6% AFFF or protein-based foams.

IS 15105 Approved Foam Concentrates

Requires foams per IS 4989 (AFFF) or IS 10993 (fluoroprotein), stable for 25% drainage time under 10 minutes.

NFPA 11 Foam Categorization

Classifies Alcohol-Resistant AFFF (AR-AFFF) for polar fuels, mandating 200:1 expansion for high-expansion mobile setups.

Selection Guide for Buyers

For petrochemical projects, choose AR foams; Kinde Fire offers BIS-certified options compliant with IS 903 nozzles and IS 636 hoses.

Equipment Performance and Testing Protocols

Rigorous testing ensures **mobile foam units** withstand industrial demands, with IS 15105 and NFPA 11 defining hydrostatic, flow, and endurance tests.

Hydrostatic and Pressure Tests

IS 15105 requires 1.5x working pressure (21 bar) hold for 10 minutes; NFPA 11 mandates 300 psi for proportioners.

Flow Rate and Proportioning Accuracy

Accuracy within ±10% at 100-1000 lpm, verified via IS 5290 branch pipes and foam makers.

Durability for Export Environments

Stainless steel 316L tanks resist corrosion; Kinde Fire’s 15+ years expertise ensures 1000+ projects compliance. Reference: BIS Certification.
