Foam Top Pourer Set Mk4
The Angus Fire Top Pourer Set (TPS) Mk4 is designed for use in foam systems for the protection of fixed roof flammable liquid storage tanks with Nitrogen inerted blankets or where tank internal pressures may reach 0.35 bar (5 psi) The Mk4 combines foam generation, vapour sealing and foam pouring in a robust, low-maintenance design and represents over 35 years of product development and operating experience. Each unit is factory calibrated to perform at a fixed flow and pressure point and can perform to the precise pressure and flow standards laid down by Underwriters Laboratories (UL) and NFPA. Units without a vapour seal are available for total flooding of open roof tanks. Four basic body sizes cover flow ranges from 75 l/min (20 US gal/min) to 3,300 l/min (870 US gal/min) at inlet pressures between 3 bar (45 psi) and 10 bar (150 psi). The discharge is enhanced by a deflector plate fitted to the outlet which disperses the finished foam against the tank wall. This ensures a rapid spread across the surface of the TPS Mk4 Dimensions (mm) A TPS 50 917 TPS 80 1,067 TPS 100 1,318 TPS 150 1,667

still under full pressure, travels up the tube, past the foam maker and bursts the heavy duty glass vapour seal disc, allowing access to the tank interior.
Foam Tube Length The length of the foam dispersal tube projecting into the tank interior can be specified by the customer. The standard or minimum length of the foam dispersal tube “E” is designed for pourers mounted (usually using the Angus Fire mounting kit) directly on to the tank wall. This positions the deflector plate at the optimum position inside the tank to spread the foam evenly around the interior. Glass Vapour Seal Disc TPS Mk4 units are fitted with a replaceable glass bursting disc suitable for tank internal pressures up to O.34 bar (5psi). Positive Bursting Disc Mechanism When the Mk4 TPS is activated, the liquid foam and water mixture is driven up the pourer inlet pipe under full operating pressure. The liquid pressure causes the air inlet flap valves at the base of the pourer to close. The liquid,
