Battery energy storage systems generate heat, exhaust gas, and — in failure events — fire, toxic smoke, and liquid discharge. The piping, suppression, and thermal systems that house them need to be designed for electrochemical environments, not adapted from HVAC or general construction specifications. Fluxera supplies and installs infrastructure built specifically for BESS.
Most industrial piping and fire suppression contractors don't understand the specific conditions that occur inside a battery container — or adjacent to one during a thermal runaway event. Lithium battery off-gas contains hydrofluoric acid precursors. Coolant systems must prevent electrolyte contact. Suppression agents must be matched to the specific chemistry and cell format.
When an EPC uses standard construction contractors for BESS infrastructure, the result is typically one of three failure modes: piping that degrades under electrolyte exposure, suppression systems that are ineffective or counterproductive in a thermal event, or thermal management that performs in lab conditions and fails at ambient temperatures in Indian climate zones.
Fluxera designs and supplies infrastructure that treats these conditions as the baseline — not the edge case.
NFPA 855 and UL 9540A compliance requires fire suppression and separation distance validation. Standard fire safety contractors typically don't have BESS-specific test data to support these requirements.
Designed to the specific geometry, chemistry, and failure modes of the battery system being installed — not adapted from general industrial specifications.
Suppression agent selection (Novec, FM-200, inert gas, water mist) matched to battery chemistry, cell format, and container configuration. The wrong agent can accelerate a thermal event rather than contain it.
Suppression system design for standard 20/40ft BESS containers, outdoor pad-mount configurations, and indoor room-based installations — including ventilation interaction analysis.
Off-gas detection (VOC/H₂), smoke detection, and thermal imaging integration — providing the detection layer required for both NFPA 855 compliance and practical incident response.
All suppression system designs are mapped against NFPA 855 requirements and validated against UL 9540A large-scale fire test data to support AHJ approval and insurance underwriting.
End-to-end delivery from design through installation and commissioning acceptance testing. Single-source accountability across the fire safety infrastructure scope.
Post-commissioning inspection schedules, agent cylinder recharge programmes, and annual compliance verification — structured for long-term operational assurance.
Thermal runaway propagation in a BESS is almost always a failure of the cooling system, not of the cell chemistry alone. We design and supply fluid infrastructure that performs in Indian ambient conditions — not just rated conditions.
Complete coolant loop design — manifold specification, flow rate calculation, heat exchanger sizing, and pump selection — optimised for the specific battery pack and deployment environment. Indian ambient temperatures (up to 48°C) require different thermal margins than European datasheets assume.
For air-cooled BESS configurations — air handling unit selection, duct design, and container thermal modelling. Includes humidity management critical in coastal and high-humidity deployments.
Coolant specification matched to battery system materials — preventing galvanic corrosion, elastomer degradation, and the gradual contamination that degrades cooling performance over a 15-year project life.
Drip tray, bund, and secondary containment design — preventing coolant or electrolyte release from reaching drainage or creating secondary hazards. Required under NFPA 855 and applicable Indian environmental regulations.
Material selection is the most frequently underestimated specification decision in BESS physical infrastructure. We supply and install the correct material for each fluid type and environment.
Primary piping for coolant circuits, drainage, and containment where chemical resistance and flexibility are required. Welded joints eliminate potential leak points common in threaded metal piping.
Higher temperature resistance than standard PVC — suitable for thermal management circuits and fire protection water supply systems where elevated temperatures are possible.
For structural piping, large-bore coolant mains, and outdoor runs where UV resistance, mechanical strength, and long-term chemical inertness are required simultaneously.
Selected for connections to battery system ports, heat exchanger interfaces, and applications where pressure rating and precision bore tolerance are critical — with full passivation for electrolyte resistance.
Full fitting schedule including isolation valves, flow meters, pressure gauges, temperature sensors, and relief valves — all specified and supplied as a matched system, not a site-assembled mix.
Piping insulation specification and supply — preventing condensation, maintaining coolant temperature, and protecting against solar gain on outdoor runs in Indian climate conditions.
Fluxera provides single-source accountability across the full infrastructure scope — from design coordination with the battery vendor through to commissioning acceptance testing. No hand-offs between separate subcontractors for interconnected systems.
We obtain the battery system's physical and thermal interface specifications and design the surrounding infrastructure around those constraints — not a generic specification.
Supply of piping, fittings, suppression equipment, and thermal system components — to a single specification, from vetted sources, with full traceability documentation.
Site installation by trained crews familiar with BESS-specific requirements — including isolation protocols, commissioning sequencing, and battery system interface procedures.
System commissioning against design specifications, including pressure testing, flow balance, suppression activation testing, and thermal management performance validation.
