Temet's HV Blast Dampers are designed to protect ventilation
systems against the long duration overpressures produced during
dust and vapor cloud explosions and the following negative
pressure. The design of HV Blast Dampers allows maximum airflow
with minimal pressure drop. The integrated fragmentation grill
protects the damper unit from flying objects and debris. Temet's HV
blast damper is rated up to 1 bar (14.5psi) of overpressure and
activates at less than 0,1bar (1.4psi). The HV blast damper is an
automatic damper and stays locked shut after the initial
overpressure to protect against the followon negative
pressure.
Temet's HV Blast Dampers are designed to protect onshore and
offshore ventilation systems in extreme conditions. Whether on a
land based refinery or chemical facility, a ship or a fixed
offshore platform, Temet HV Blast Dampers are low maintenance and
give reliable protection due to their outstanding corrosion
resistant construction. AISI 316l stainless steel or hot dipped
galvanized blast dampers are standard options for each
size.
Temet's HV Blast Dampers are ideal for petrochemical HVAC
protection. The HV blast damper's optimal airflow design allows
maximum airflow with minimal pressure drop. Corrosion resistant
materials and designed specifically for the situations encountered
in a vapor cloud explosion ensure that Temet's HV blast damper
remains functional while protecting HVAC ducts and equipment
against blast.
