Medium Expansion Foam Generator
225–1200+ LPM | Fixed & Portable Models | 50:1 to 100:1 Expansion | SS304/316 Construction
Product Overview
The Medium Expansion Foam Generator represents advanced volumetric foam generation technology engineered to produce stable, high-expansion foam blankets with expansion ratios ranging from 50:1 to 100:1 (50–100 cubic meters of finished foam per cubic meter of foam solution), optimized for rapid three-dimensional fire suppression and vapor mitigation in confined spaces including ship engine rooms, aircraft hangars, industrial warehouses, basement car parks, cable tunnels, transformer vaults, and liquid storage containment areas where conventional low expansion foam application provides insufficient volumetric filling capability or extended fire knockdown times. Available in portable configurations featuring lightweight stainless steel construction with 63 mm male instantaneous couplings for rapid deployment via fire brigade hose lines at flow capacities of 225–600 LPM, and fixed installation models with ANSI flanged inlet connections for permanent mounting in high-risk areas at capacities ranging from 225 LPM to 1200+ LPM with custom-engineered solutions available for specialized industrial applications, these generators incorporate precision-machined stainless steel nozzle arrays, aerodynamic cone geometries for optimal air entrainment, and corrosion-resistant SS304/316 construction ensuring reliable performance in marine, offshore, petrochemical, and industrial fire protection systems serving export markets including UAE, Saudi Arabia, Singapore, Kenya, Nigeria, and throughout 26+ countries across 6 continents.
Operating on the fundamental principle of high-velocity foam solution discharge through precision nozzle arrays that atomize the pre-proportioned foam solution (water + foam concentrate proportioned at 3–6% via upstream inline inductor or balanced pressure proportioner) into fine droplets which are mechanically agitated by aerodynamic screens and baffles to entrain large volumes of atmospheric air, creating stable medium expansion foam with uniform bubble structure, controlled drainage characteristics (25% drainage time of 3–5 minutes typical), and effective thermal insulation properties for sustained Class B fire suppression and vapor control. Each generator undergoes comprehensive factory acceptance testing including foam expansion ratio verification with actual AFFF, FFFP, or synthetic foam concentrates, foam quality assessment measuring drainage time and bubble uniformity, nozzle flow distribution verification ensuring uniform foam generation across the entire generator screen area, and corrosion resistance testing validating material compatibility with marine and industrial atmospheres. With optional inline inductor integration packages available—automatically matched to generator LPM capacity and featuring stainless steel construction with foam concentrate pick-up tubes for standalone operation—complete turnkey foam generation systems can be supplied for immediate commissioning. Trusted by ship classification societies (ABS, DNV-GL, Lloyd's), airport authorities, petrochemical facility operators, fire brigade organizations, and industrial emergency response teams worldwide, Kinde Fire's medium expansion foam generators deliver the proven volumetric filling capability, foam quality consistency, mechanical durability, and complete testing documentation required for code-compliant foam fire suppression system installations per NFPA 11, IMO SOLAS, EN 13565, and international marine/industrial fire protection standards.

Standard portable and fixed foam generators in SS304 construction typically require 3–4 weeks for stainless steel fabrication, nozzle array installation, foam expansion testing with actual concentrate, drainage time verification, and complete quality documentation including foam test reports. SS316 marine-grade models or custom LPM capacities above 1200 LPM may add 1–2 additional weeks for specialized material procurement and extended foam quality validation testing. Large orders (20+ units) for shipyard or industrial projects may require 5–6 weeks for sequential fabrication and individual unit foam testing. Express manufacturing and air freight options available for emergency replacement requirements on offshore platforms, ship engine rooms, or critical industrial installations requiring rapid commissioning timelines.
Portable models with 63 mm male instantaneous couplings are optimal for fire brigade operations, emergency response scenarios, and applications requiring flexible foam generator positioning via temporary hose lines—ideal for industrial warehouses, outdoor tank farms, and situations where foam discharge point may vary based on fire location. Fixed models with ANSI flanged inlet connections are preferred for permanent installations in ship engine rooms, aircraft hangars, basement car parks, cable tunnels, and transformer vaults where foam generators are hard-piped to dedicated foam distribution systems with upstream proportioning equipment and automatic activation capabilities. For facilities requiring both portable response capability and fixed protection zones, combination approach using fixed generators for high-risk permanent areas and portable generators for emergency response teams provides maximum operational flexibility. Capacity selection depends on compartment volume and required filling time: 225–450 LPM suitable for small engine rooms and equipment vaults, 600–900 LPM for medium warehouses and hangars, 1200+ LPM for large aircraft hangars and industrial facilities requiring rapid volumetric foam filling.

What is a Medium Expansion Foam Generator?
A Medium Expansion Foam Generator is an advanced fire suppression device engineered to produce large volumes of stable, adherent foam with expansion ratios ranging from 50:1 to 100:1 (50–100 cubic meters of finished foam blanket per cubic meter of incoming foam solution), optimized for rapid three-dimensional filling and total fire engulfment in enclosed and semi-enclosed spaces where conventional low expansion foam (3:1 to 10:1) provides insufficient volumetric coverage or extended fire knockdown times. The generator comprises a precision-fabricated stainless steel body housing an array of specially-designed nozzles that discharge pre-proportioned foam solution (water with 3–6% foam concentrate proportioned via upstream inline inductor or balanced pressure system) at high velocity through aerodynamic screens, cones, and baffles that mechanically agitate the solution stream while entraining massive volumes of atmospheric air through venturi effect and turbulent mixing, creating stable medium expansion foam with uniform bubble structure, controlled drainage characteristics (25% drainage time typically 3–5 minutes), and effective thermal insulation properties for sustained Class B flammable liquid fire suppression, vapor mitigation, and inerting capability in ship engine rooms, aircraft hangars, industrial warehouses, basement car parks, cable tunnels, transformer vaults, and hazardous material storage areas where rapid compartment filling with persistent foam blankets represents the optimal fire protection strategy compared to water sprinklers, gaseous suppression, or conventional foam application methods.
