Product overview
HD-INERTSYS provides engineered inert-gas suppression using IG-55, IG-541, IG-100 or IG-01. The manufacturer lists 80- and 140-litre cylinder options with 200- or 300-bar storage, selected for the required concentration and volume. Selector or directional valves support the protection of multiple areas from a common cylinder bank. The design uses the specified VdS calculation method.

Applications
Enclosed hazards selected for inert-gas protection. Confirm concentration, enclosure integrity, pressure relief and personnel safeguards in the engineered design.
Selection and project integration
Share the protected-space drawings, hazard description, equipment schedule and project specification with UDCT. The technical review should establish the selected system configuration, required quantity, installation constraints and interfaces with the detection and control equipment. For gaseous suppression, enclosure integrity, pressure relief, discharge acoustics and personnel safeguards must be assessed as part of the engineered design.
The published model designation is a product reference, not a final bill of materials. Agent quantities, pipe sizing, nozzle selection, storage arrangements and release logic depend on the approved design. Use the current manufacturer instructions for installation, testing and maintenance, and confirm availability with UDCT before procurement.
