TSX -20°C Flammable Materials Storage Laboratory Freezers
Conventional freezers are not suitable for storing flammable materials. Such units
have components in their electrical and refrigeration systems that can trigger
explosions of flammable air and vapor mixtures inside the unit.
Flammable Material Storage (FMS) freezers have no internal components that
could trigger an explosion or fire inside the unit. FMS freezers are designed for
use in locations which are not classified as hazardous by the Authority Having
Jurisdiction (AHJ). Under normal operating conditions, the buildup or presence
of flammable vapors will not occur in the environment outside the unit.
