Thermatic Dome

Small Room Protection

At Peripheral Manufacturing, Inc., we are your source for waterless fire suppression systems, automatic fire suppression systems, and modular fire suppression system options. We offer various fire suppression systems and components that support the Aero-K® / Stat-X® platform. One of these components is our thermatic dome for the protection of small room environments.

The Thermatic Dome is available in 12, 33, 56, and 72 pound sizes!

Dry Chemical Suppression System

The Thermatic Canister system is ceiling mounted in the middle of the hazard area. It uses heat detection of fire by a U.L./U.L.C./FM Fast Response sprinkler bulb at 155˚F, 175˚F, or 200˚F to initiate agent deployment. The spray pattern of the sprinkler head maximum for the single container covers a volume of 300 up to 1,900 cu.ft.


Electrical actuator “Squib” available to link up to 4 systems together for increased room coverage. Electrical actuator can also be linked into wiring circuit for manual operation and/or wiring smoke or heat detectors.

Class A & C Fire Hazards

Determine volume of enclosure to be protected:

L x W x H = ft3 x 0.0379 (4.2% Design) = lbs needed
L x W x H = m3 x 0.6101 (4.2% Design) = kg needed
Or reference Class B fuels Design Concentration.
