Where Flourguard Flexible Patches Are Typically Deployed
Flourguard is most useful in three deployment scenarios. First, cable joints and terminations: the patch wraps around the joint, conforming to the geometry and triggering directly at the heat source. Second, busbar connections in low-voltage switchgear: the patch sticks to the busbar surface and protects the bolted joint, which is the most common fault location in switchgear surveys. Third, inside distribution cabinets where the layout is non-standard or where a cylindrical extinguisher cannot physically fit.
The flexible substrate is rated for continuous operation at ∐40°C to +120°C and survives short-term exposure to 200°C without degradation. The substrate is non-conductive and does not affect the dielectric properties of the protected joint. CHILION supplies five standard sizes (60×60mm, 80×80mm, 100×100mm, 120×120mm, and 150×150mm) and a custom-size service for OEM customers.
For integrators, the key sizing rule is: the patch should cover the heat source plus an additional 30mm margin in every direction. The fault arc typically radiates heat in a spherical pattern, and the margin ensures the patch triggers before the underlying insulation has reached its auto-ignition temperature. CHILION engineering can issue a per-cabinet layout drawing if the integrator provides a single-line diagram or a site photo.
Differences from Conventional Fire-Suppression Patches
Conventional fire-suppression patches in the cabinet-fire market are typically ceramic-encapsulated chemical agents that activate only at very high temperatures and that lose structural integrity after one activation. CHILION Flourguard is engineered differently — the active agent is micro-encapsulated, the activation threshold is tuned to cabinet thermal fault profiles rather than open-flame profiles, and the structural integrity is preserved across multiple thermal cycles. Each of these three differences is independently valuable, but together they let operators specify Flourguard as a continuous-protection device rather than as a one-shot device, which is the procurement shift that unlocks multi-year service contracts.

Activation Cycling and Five-Year Service Contract Implications
Because Flourguard preserves structural integrity across multiple thermal cycles, the five-year service contract shifts from a one-shot replacement-after-event model to a periodic inspection and re-certification model. The periodic inspection includes a thermal-soak test on a representative patch from the cabinet population to confirm the activation threshold has not drifted, and a visual check on patch face contamination. The re-certification cost per cabinet per year is approximately one-fifth of the one-shot replacement cost, which is the arithmetic that drives the five-year service contract adoption in mid-size industrial and utility customers.
Annual re-certification cost is approximately one-fifth of one-shot replacement — the foundation of the five-year service contract.
Compatible Cabinet Architectures
Flourguard is rated for a wider cabinet architecture range than the previous generation of cabinet-fire patches. Compatibility covers indoor metal-clad switchgear from 6 kV to 40.5 kV, withdrawable breaker compartments, fixed-pattern breaker compartments, and busbar trunking interfaces up to 4000 A. Compatibility does not cover open-frame busbar runs in non-enclosed switchrooms, since the patch requires a defined thermal mass to provide a stable activation reference. For open-frame sites the procurement team routes the customer to the gaseous-suppression product line instead, because the engineering case for cabinet-mounted versus room-volume is materially different.

Insurance and Warranty Programme
The Flourguard warranty programme extends the standard one-year mechanical warranty with a five-year performance warranty against activation-threshold drift, conditional on the periodic inspection cadence being maintained. Operators who maintain the inspection cadence can extend the performance warranty to seven years with the annual re-certification. Insurance carriers increasingly recognise the Flourguard warranty programme as a credit in their cabinet-fire underwriting, and several carriers now offer premium reductions for sites that maintain the CHILION service contract. The warranty document is part of the customer-facing risk-management bundle that CFOs request during the procurement qualification phase.

Quotation Triage Patterns in Tender Responses
Engineering teams responding to cabinet-fire-suppression tenders see three quotation triage patterns. Triage pattern one: the budget has already been allocated for active protection, and the customer is asking for a vendor-fit question. Triage pattern two: the budget envelope is set for general cabinet-fire-suppression, and the customer is asking for a technology comparison. Triage pattern three: the budget is allocated for cabinet-fire-suppression at the framework level, and the customer is asking for per-site roll-out scheduling. The CHILION sales engineering team has published quote templates that pre-load the engineering content for each triage pattern, which compresses the response time by approximately 50 percent relative to a from-scratch response. The quote templates are part of the partner enablement pack that new channel partners receive during the certification workshop. The quote templates also map to the platform service-contract per-cabinet pricing, which is the operational reason a multi-site roll-out can be quoted on a single response document.
Customer Reference Visits by Geography
Customer reference visits by geography are part of the platform service-contract standard offering, and the visits are typically arranged by the regional sales engineering team for the largest prospective customers during their qualification phase. A reference visit typically consists of a half-day on-site meeting with the existing customer's maintenance team, a one-hour walkthrough of the existing customer's cabinet-fleet operational data, and a one-hour closing session with the existing customer's procurement team. The reference visit duration is calibrated to the prospective customer's procurement timeline, and the timeline alignment is the operational reason the reference visit compresses the qualification phase by approximately 30 percent. The reference visit costs the existing customer approximately three working days of staff time across the half-day meeting, walkthrough, and closing session, which is the operational reason existing customers tend to gate the visit with a senior maintenance team member's time. The reference visit programme is the operational reason the platform service contract's renewal rate has remained above the industry benchmark across the multi-year window.
Procurement Specification Templates
Procurement specification templates for cabinet-fire-suppression projects cover the line-item structure that large fleet operators use during tender response review. The templates include the cabinet-population map input format, the per-cabinet line-item structure, the bracket-fit specification language, the coating-application specification, and the post-event inspection specification. Customers specifying the platform in fleet-scale tenders typically request the templates during the qualification phase and integrate them into their internal procurement workflow. The templates are part of the customer-facing risk-management bundle, and the operational asset the procurement team relies on across the multi-year service-contract window. The templates are also the operational reason the platform's per-cabinet pricing is consistently benchmarked against the customer's per-cabinet expected cost envelope.
Frequently Asked Questions
What is the difference between Flourguard and generic PFCS?
Flourguard is the CHILION brand name for PFCS. There is no functional difference in the suppression mechanism; Flourguard is manufactured by CHILION to the same specification as the PFCS generic product. Customers specifying by brand should use the Flourguard part number; customers specifying by generic spec can use the PFCS part number.
Can Flourguard be cut to size?
Cutting the patch is not recommended because it changes the trigger characteristics and invalidates the warranty. CHILION supplies five standard sizes and a custom-size service for OEM customers. Custom sizes require a minimum order quantity and typically 4 weeks of lead time.
Is Flourguard safe for use inside enclosed cabinets with personnel access?
Yes. Flourguard releases FK-5-1-12 (Novec 1230), which is a clean agent with a NOAEL well above the design concentration for typical cabinet volumes. Personnel can re-enter the cabinet area immediately after discharge, subject to the standard post-event safety briefing.
