DEMA 900-WC Wall-Mount Foam Unit – 170 L/min Concentrate

Description

Permanent, high-volume foam power from concentrate — the DEMA 900-WC wall mounts once and delivers up to 170 litres of sanitising foam per minute, shift after shift.

The DEMA 900-WC Wall-Mount Foam Unit is a high-volume, compressed-air-powered foaming system engineered for permanent installation in commercial food processing, cold storage, pharmaceutical, and hygiene-critical industrial environments. Unlike tank-based mobile foamers that require pre-mixing and manual transport, the 900-WC draws directly from chemical concentrate — diluting automatically at your chosen ratio and delivering up to 170 litres of thick, clinging sanitising foam per minute through a stainless steel wand with a spray reach of 7–9 metres. Always ready, precisely dosed, and requiring no manual mixing.

Mounted permanently to the wall and connected directly to your chemical supply, the 900-WC eliminates pre-mixed tank management while giving operators a compressed-air-powered system that requires no electrical connection at the spray point — making it safe and compliant for wet washdown zones. The fibreglass control box houses water pressure regulation to maintain consistent foam quality across varying supply pressure, while adjustable metering tips set dilution anywhere from 14:1 to 320:1 to match your sanitation protocol exactly. Three pump seal options — Santoprene, Viton, and Kalrez — ensure chemical compatibility across a wide range of cleaning, sanitising, and disinfecting products, and a quick-change pump with a 15-metre standard hose complete a system built for maximum uptime in high-demand commercial environments.

Why professionals choose the DEMA 900-WC

• Concentrate-Draw — No Pre-Mixing Required — Draws directly from chemical concentrate and dilutes automatically at your set ratio — eliminating manual mixing, reducing product waste, and ensuring consistently dosed, food-safe foam every cycle without pre-preparation or tank refilling.
• High-Volume Output: Up to 170 L/min — Delivers 75–170 litres of sanitising foam per minute with a 7–9 metre spray reach — providing fast, thorough coverage of large wall, floor, and equipment surfaces in food processing and industrial washdown operations.
• Adjustable Dilution 14:1 to 320:1 — Metering tips are fully adjustable across a wide dilution range — a single wall-mount unit can serve multiple sanitation protocols and chemical products at precisely the right concentration without replacing the unit.
• Chemical-Compatible Pump Seal Options — Available with Santoprene, Viton, or Kalrez pump seals to match your chemical program — ensuring compatibility with general detergents, industrial sanitisers, caustic cleaners, acids, and aggressive disinfecting agents.
• Compressed Air Powered — No Electricity at Spray Point — Operates from compressed air with no electrical requirement at the spray location — ideal for wet environments, washdown zones, and hygiene-critical areas where electrical safety standards restrict powered equipment.

Specifications

Where the DEMA 900-WC works best

• Food Processing Plant Sanitation — Wall-mount in production zones, processing areas, and equipment bays for fast, high-volume foam sanitation at shift changeover — concentrate draw ensures every wash is precisely dosed and food-safe compliant without manual chemical mixing.
• Cold Storage & Refrigeration Facility Cleaning — Permanently installed in cold store washdown zones where pre-mixed mobile units are impractical — concentrate draw from an external drum and compressed-air operation makes the 900-WC ideal for regular CIP foam applications in refrigerated environments.
• Meat & Poultry Processing Hygiene — High-output foam coverage across conveyor systems, cutting areas, and large processing surfaces — stainless steel wand and chemical-resistant seal options handle the aggressive sanitisers required in meat and poultry hygiene environments.
• Pharmaceutical & Healthcare Manufacturing — Precise dilution control and Viton or Kalrez seal compatibility support pharmaceutical-grade sanitation protocols where accurate chemical concentration and material compatibility with aggressive disinfectants are mandatory.
• Industrial & Commercial Washdown Stations — Any fixed washdown point in breweries, large-scale commercial kitchens, industrial facilities, or warehousing — the 900-WC provides always-ready, high-volume foam from concentrate without the setup time and downtime of tank-based mobile units.

Frequently asked questions

How does the DEMA 900-WC differ from the mobile foam units (910 and 925)?

The key differences are mounting style and chemical source. The DEMA 910 and 925 are mobile cart-mounted units that use pre-mixed solution carried in a tank — ideal for moving across a facility without fixed plumbing. The 900-WC is permanently wall-mounted and draws directly from chemical concentrate, diluting automatically at your set ratio. This eliminates manual mixing and tank refilling, making the 900-WC the right choice for fixed washdown stations in food processing, cold storage, and industrial environments where a permanent, always-ready, high-output system is preferred.

What is the difference between Santoprene, Viton, and Kalrez pump seals?

The seal material determines which chemicals the pump can handle safely. Santoprene is suitable for a broad range of general cleaning detergents and sanitisers. Viton offers improved resistance to oils, fuels, and many industrial chemicals. Kalrez provides the highest chemical resistance — suitable for aggressive acids, strong oxidisers, and specialised disinfectants used in pharmaceutical and food processing environments. Contact Prochemicals to confirm the right seal for your specific chemical program.

Does the DEMA 900-WC require electrical installation?

No. The 900-WC is compressed-air powered — there is no electrical connection required at the spray point. Installation requires a compressed air supply (275–550 kPa / 5–10 CFM) and a water supply (275–690 kPa) connected to the wall-mount control box. The absence of electrical wiring at the spray location makes it safe and compliant for wet, washdown, and hygiene-critical environments.

Can the dilution ratio be adjusted on-site after installation?

Yes. The 900-WC uses adjustable metering tips to set the dilution ratio anywhere from 14:1 to 320:1. This allows the same wall-mount unit to be used for different sanitation protocols, or switched between chemicals when your program changes, without replacing the unit. Contact Prochemicals for guidance on the correct metering tip setting for your target dilution and chemical type.
