TKO Nozzle is Designed with a Reservoir Housing

The TKO nozzle with reservoir housing adds a built-in chamber inside the nozzle body, holding a small volume of firefighting foam concentrate or additive ready for immediate mixing with water flow. This housing sits between the hose connection and the discharge tip, drawing from the reservoir automatically as water passes through, without needing a separate inline foam eductor attached upstream. Reservoir capacity typically holds 200 to 500ml of concentrate, enough for several minutes of foam-assisted discharge during initial fire attack before requiring a refill.

Body material remains brass or aluminum alloy, consistent with standard TKO nozzle construction, keeping the added reservoir housing lightweight enough for one-person handling despite the extra internal chamber. Flow rate stays in the same 95 to 250 litres per minute range as standard TKO models, with the reservoir affecting concentrate mixing rather than overall water output. A mixing ratio control, usually a small dial or valve near the reservoir inlet, lets the operator adjust how much concentrate blends into the water stream based on fire type and intensity.

Refilling the reservoir happens through a sealed cap on top of the housing, designed to prevent spillage during active use or while the nozzle sits connected to a charged hose line. Some models include a sight window, letting the operator check remaining concentrate level without disconnecting or opening the reservoir mid-operation.

Fire departments use reservoir-equipped TKO nozzles when foam-assisted suppression improves knockdown speed on flammable liquid or Class B fires. Industrial fire brigades at fuel storage and chemical processing sites rely on this feature for faster response without connecting separate foam equipment. Airport fire and rescue crews also use these nozzles during fuel-related aircraft emergencies.

Tactical Supply Pakistan supplies TKO nozzles with reservoir housing to fire departments, industrial fire brigades, and airport rescue services across Pakistan. Reservoir capacity and mixing ratio range are matched to expected fire class and response needs.
