Vertical pressure propotioning system (twin bladder tank) with foam concentrate inside of the bladder mod. SE-MXC-H-I

Similar to the proportioning system described above, this system comprises two tanks, allowing continuous fire-fighting capability even while one tank is being re-filled or serviced (including bladder replacement).
