Inline Foam Inductor
225–1800 LPM | Portable Variable/Fixed & Fixed Installation | Precision Foam Proportioning | Aluminum/SS304 Construction
Product Overview
The Inline Foam Inductor represents the critical precision component in modern foam fire suppression systems, engineered to deliver consistently accurate foam concentrate proportioning through venturi-effect hydraulic induction across a wide range of flow rates and pressures without requiring external power or complex control systems. Available in portable configurations (variable adjustable 3–6% or fixed 3% / 6% proportioning) for rapid deployment with mobile foam equipment and fixed-installation models (225 to 1800+ LPM) for permanent integration into foam chambers, monitors, and sprinkler systems, these inductors utilize precision-machined internal geometries to create controlled pressure differential that automatically draws foam concentrate from storage tanks and mixes it with pressurized water at specified proportioning ratios regardless of minor system pressure fluctuations.
Manufactured in corrosion-resistant aluminum alloy or marine-grade stainless steel 304 with options for gun metal or SS304 end connections, each inductor undergoes rigorous flow testing and foam proportioning verification before dispatch to ensure compliance with manufacturer's rated capacity and proportioning accuracy within ±10% tolerance across the specified pressure range (typically 5–12 kg/cm² depending on model). Portable models feature 63 mm male and female instantaneous couplings per IS/BS standards for tool-free connection to hose lines and foam branches, while fixed-installation models accommodate customer-specified flange standards (ANSI B 16.5, DIN, BS) for welding or bolting into permanent piping systems. The integral pick-up tube (reinforced PVC braided hose for portable units, stainless steel pipe for fixed installations) extends into foam concentrate drums or bulk tanks to ensure consistent foam supply throughout discharge operations. With thousands of units operating reliably in refineries, tank farms, petrochemical facilities, aviation fuel depots, and industrial plants across UAE, Saudi Arabia, Qatar, Singapore, UK, USA, and 20+ countries worldwide, Kinde Fire's inline foam inductors deliver the proven hydraulic precision and mechanical durability required for mission-critical foam suppression systems where accurate proportioning directly determines fire knockdown effectiveness and operational safety.

Frequently Asked Questions (FAQ)
We provide complete material test certificates (MTC) for aluminum and stainless steel components, hydrostatic pressure test reports (25 kg/cm²), flow capacity verification curves at multiple pressure points, foam proportioning accuracy test data performed with actual foam concentrate (AFFF, FFFP, or customer-specified type), dimensional inspection reports, and ISO 9001:2015 quality documentation. Optional NABL lab testing and third-party proportioning verification available for international EPC projects and FM/UL approval requirements.
Standard portable and fixed installation inductors (225–900 LPM) typically require 2–3 weeks for CNC machining, assembly, flow testing, proportioning verification, and quality documentation. Custom flow capacity models (1000+ LPM) or special flange/material combinations may require 3–4 weeks for engineering, tooling, and testing. Large orders (50+ units) may require 4–6 weeks for sequential machining and individual testing. Air freight options available for urgent project requirements.
Variable proportioning inductors (adjustable 3–6%) are optimal for facilities using multiple foam concentrate types or where future flexibility is desired, allowing field adjustment without equipment replacement. Fixed proportioning inductors (3% or 6% only) are preferred for dedicated foam systems using single concentrate type, offering simpler operation and slightly lower cost. For mobile foam equipment serving multiple facilities or concentrate types, variable models provide maximum operational flexibility. For fixed installation foam chambers or monitors with specified concentrate type, fixed models deliver adequate performance at lower initial cost.
Yes, our fixed installation inductors are available in any flow capacity from 225 to 5000+ LPM to match specific foam monitor, chamber, deluge valve, or sprinkler system hydraulic requirements. Custom inductors require detailed application data including desired flow rate (LPM), available inlet pressure (kg/cm²), foam concentrate type and proportioning ratio, downstream piping configuration, and flange standard. We provide hydraulic sizing calculations, pressure drop curves, and proportioning accuracy verification as part of custom engineering process, typically adding 1–2 weeks to standard lead time depending on complexity.
We provide comprehensive global support including spare parts supply (pick-up tubes, seals, connection hardware) typically dispatchable within 3–5 working days worldwide, 24/7 WhatsApp technical support for troubleshooting proportioning issues or installation questions, complete operation and maintenance manuals with flushing procedures, remote proportioning verification support via video call, and field service coordination for large-scale foam system commissioning. Annual flushing and proportioning accuracy testing recommended; we can provide testing protocols and calibration services. All units include 12-month warranty covering manufacturing defects; extended service agreements available for critical refinery and offshore installations.
What is an Inline Foam Inductor?
An Inline Foam Inductor is a specialized hydraulic device engineered to automatically proportion foam concentrate into pressurized water flow through venturi-effect suction without requiring external power, control systems, or operator adjustment during foam fire suppression operations. The device comprises a precision-machined body containing an internal flow path with calibrated throat restriction that creates controlled pressure differential when water flows through the unit at specified inlet pressure (typically 5–12 kg/cm²). This pressure differential generates suction force transmitted through a foam concentrate pick-up tube extending into concentrate storage drums or bulk tanks, drawing concentrate at precise proportioning ratios (3%, 6%, or variable 3–6% depending on model) and mixing it with the main water stream to create foam solution that feeds downstream foam-making devices (branch pipes, monitors, chambers, sprinklers). Available in portable configurations with instantaneous couplings for rapid deployment with mobile foam equipment and fixed-installation models with flanged connections for permanent integration into foam system piping, inline foam inductors represent the most reliable proportioning technology for industrial, petrochemical, aviation, and marine foam suppression applications where accurate foam concentrate mixing directly determines fire knockdown effectiveness and where power-independent operation ensures functionality during electrical system failures common in major fire scenarios.
