DESCRIPTION
ALCOSIN LV are alcohol resistant aqua film forming fire fighting foam concentrates produced carefully controlled blend of high activity selective special C6 fluorosurfactant and hydrocarbon surfactants with various solvents, preservatives, stabilizers and selective special chemical additives to provide superior fire and vapor suppression for Class B, polar solvent and hydrocarbon fuel fires. ALCOSIN solution utilizes three suppression
mechanisms intended for rapid fire knockdown and superior burnback resistance. Newtonien (non-viscose) formula provides reliable performance even on the strongest fuels.
APPLICATIONS
ALCOSIN LV is suitable for use in situations where hydrocarbons ( such as diesel fuel, gasoline, crude oil ) and where polar solvents (such as alcohols, ketones, esters and ethers) are stored, processed or transported. It is used extensively by hemical, oil and petrochemical companies for storage tank fire protection.
ALCOSIN LV is principally recommended for protection against fire in :
- Polar Solvents and Hydrocarbon solvents storage tanks
- Chemical Plants, Petroleum Plants and Refineries
- Flammable liquid containment areas
- Offshore platforms, Marine terminals and vessels
- Hydrocarbon stroge tanks and power stations
- Process areas, Warehouses
C6 FLUOROCHEMICALS EQUIPMENT
The environmentally friendly ALCOSIN LV formulation contains short-chain C6 fluorochemicals produced using a telomere-based process. The telomere process does not produce PFOS and the C6 fluorochemicals do not break down to produce PFOA. The fluorochemicals used in the concentrate comply with the objectives of the EPA 2010/15 PFOA Management Program.
EQUIPMENT
ALCOSIN LV is suitable for use in combination with :
Soft or hard, fresh or sea water.
Dry powder extinguishing agents either separately or as twin agent systems.
ALCOSIN LV properties do not change in case of frost. It recovers its initial properties as soon as it is defrosted.
ALCOSIN LV can be applied with aspirating and non-aspirating discharge devices. Aspirating discharge devices typically produce expansion ratios from 5 to 10, depending on the type of device and the flow rate. Non-aspirating devices, such as handline water fog/stream nozzles or standard sprinkler heads, typically produce expansion ratios from 2:1 to 4:1.
Medium-expansion discharge devices typically produce expansion ratios from 20:1 to 80:1.
