The Defender Tank Protection system is an air aspirating foam appliance designed to provide effective full-surface and rim seal fire suppression for storage tanks. A semi or fixed system appliance provides a quicker response time and less manpower than a portable, large volume delivery approach. The Defender requires less flow rate due to lower recommended application densities while exposing fewer personnel to a hazardous situation.
Please send inquiries with your tank diameter, type of tank and service for a defender package configured for your tank.
