Pendant sprinkler heads for wet-pipe + pre-action systems — installed pointing downward from ceiling. Standard response (5mm bulb) + quick response (3mm bulb) + intermediate temperature (135°F / 57°C, 175°F / 79°C, 200°F / 93°C) variants. K=5.6 metric (K=8.0 imperial), K=8.0 metric, K=11.2 metric available. UL Listed / FM Approved / IS 9972. Standard for office, warehouse, manufacturing-floor coverage.
Upright sprinkler heads for wet-pipe + pre-action systems — installed pointing upward from horizontal piping. Same K-factor + temperature + bulb-response options as pendant. Used where pendant installation isn't suitable — typically in high-bay warehouses, narrow-pipe-routing scenarios. UL / FM / IS 9972 compliant.
Sidewall sprinkler heads for wet-pipe systems where ceiling installation isn't practical — corridors, narrow rooms, residential occupancies. Horizontal sidewall + vertical sidewall variants. Standard response + quick response + extended-coverage (EC) variants. K=5.6, K=8.0 metric available.
Concealed pendant sprinklers with cover plate — for office + retail + hospitality applications where exposed pendant heads are aesthetically undesirable. Cover plate releases at fusing temperature ≤57°C; sprinkler operates at design temperature. Standard response + quick response options.
Early Suppression Fast Response heads are the right answer for rack storage above roughly 7.6 m, and we will design and supply the scheme to NFPA 13 and FM Global Data Sheet 8-9. HD Fire Protect does not manufacture an ESFR head, so the heads come from a manufacturer that does, with their listing certificate, while the valves, water spray nozzles and monitors on the same system come from HD Fire. Ask us and we will name both on the quotation.
Dry-pendant + dry-upright sprinklers for cold-storage / freezer applications (pendant water column drains to prevent freezing). Pre-action sprinklers for water-sensitive areas (data centres, museums, electrical rooms). Deluge sprinklers (open heads, no fusible element) for transformer-yard + LPG-storage tank-cooling applications.
Standard property values across the range. TDS / MSDS / per-batch COA available on enquiry.

Where HD Fire sprinkler systems ship from our Hyderabad warehouse — by NFPA hazard class + occupancy type.
Standard pendant + concealed pendant + sidewall sprinklers for Light Hazard occupancies (offices, retail, hotels, hospitals). K=5.6 / K=8.0 standard-response sprinklers per NFPA 13 Light Hazard. Concealed pendant variants common in hospitality + premium office spaces.
Standard pendant + upright sprinklers for Ordinary Hazard Group 1 + 2 occupancies (manufacturing, assembly, light warehouse). K=5.6 / K=8.0 / K=11.2 standard-response sprinklers per NFPA 13 OH1/OH2. Quick-response variants for life-safety-critical areas.
High-piled and racked storage of plastics, paper, foam and palletised goods needs ESFR or in-rack heads. HD Fire does not make ESFR — we design the scheme to NFPA 13 and FM Global Data Sheet 8-9, source the heads from a manufacturer that does, and supply the HD Fire valves and water spray on the same system.
Dry-pendant + dry-upright sprinklers for cold-storage / freezer applications where wet-pipe water columns would freeze. Specialised installation requirements + NFPA 13 cold-storage chapters apply. Common for food-and-beverage cold-storage + pharma cold-chain warehouses.
Pre-action sprinkler systems with concealed / standard pendant heads for water-sensitive areas — data centres, server rooms, museums, archive storage. Pre-action prevents accidental water-discharge on false alarm. Common for tier-2 / tier-3 / tier-4 data centre installations.
Deluge sprinkler systems (open heads, no fusible element) for refinery + petrochemical above-ground storage tank cooling, LPG / propane / butane storage tank cooling, fire-water-spray system applications. Pairs with our refinery fire protection and hydrant valve portfolios.
For fire-system designers + EPC contractors selecting sprinkler equipment — UL / FM / BIS approval status, K-factor selection, and BOQ accuracy shape system reliability + insurance + factory-licence compliance.

Common questions from MEP consultants + EPC contractors + factory safety teams sourcing HD Fire sprinkler systems through Vasundhara.
Standard-response (SR) sprinklers have 5 mm glass bulb (or fusible link) — Response Time Index (RTI) 80-150 m·s½. Activation lag is moderate. Quick-response (QR) sprinklers have 3 mm glass bulb — RTI 30-50 m·s½. Activation is faster. NFPA 13 specifies QR sprinklers for life-safety occupancies (residential, hospitals, hotels) where faster activation reduces life-safety risk. SR sprinklers are acceptable for most commercial + industrial occupancies. ESFR sprinklers use the fastest-response RTI category (Fast Response, FR).
K-factor selection depends on occupancy hazard + design density per NFPA 13: Light Hazard — K=5.6 (typical); Ordinary Hazard 1 — K=5.6 / K=8.0; Ordinary Hazard 2 — K=8.0 / K=11.2; Storage applications — K=14, K=16.8, K=22.4, K=25.2 (ESFR sprinklers). Higher K-factor delivers more water flow at given pressure — important for high-density / high-piled-storage protection. Hydraulic calculations per NFPA 13 confirm the selected K-factor + pressure / flow at the most-remote sprinkler. Vasundhara provides hydraulic calculation support for projects where we are the supply partner.
Yes. HD Fire's complete sprinkler range (pendant, upright, sidewall, concealed, dry-type, pre-action) carries UL Listing + FM Approval + IS 9972 compliance. Per-shipment approval certificates provided. Suitable for fire department NOC submission, factory-safety audit, MEP consultant submittals, EPC project documentation, and insurance compliance.
ESFR (Early Suppression Fast Response) sprinklers are high-K-factor sprinklers designed to actively suppress (not just control) high-piled-storage fires. Required by NFPA 13 for: high-piled storage (typically >3.66m / 12 ft pile heights), hazardous-class storage materials (Class IV commodities, plastics, rubber, paper), automated storage / retrieval systems (ASRS). ESFR eliminates the need for in-rack sprinkler heads in many installations — ceiling-level ESFR alone provides full protection. Common in modern warehouse-distribution centres + tier-1 logistics facilities. We supply ESFR from manufacturers who make it, alongside HD Fire valves, water spray nozzles and monitors on the same system.
Generally yes — sprinkler heads + sprinkler-system valves (alarm valves, deluge valves, pre-action valves) are independently specified per NFPA 13. Mixing manufacturers is acceptable provided each component carries the required approvals (UL / FM / BIS). However, for system-coordination simplicity + warranty consolidation, single-vendor sourcing through Vasundhara (HD Fire complete-system supply) is typically preferred — single accountable contact for system-performance issues.
Common-spec items (standard pendant K=5.6, upright K=5.6, sidewall K=5.6, concealed pendant) — 2-5 working days from Secunderabad warehouse stock. ESFR heads are not supplied from HD Fire — lead time depends on the manufacturer we source them from, typically 2-4 weeks, quoted per project. Specialty dry-type + pre-action sprinklers — 2-3 weeks from factory dispatch. Bulk volumes (5,000+ heads for tier-1 warehouse projects) typically quoted on 4-6 week lead time with project-pricing terms.
