Sales-engineer tool for sizing and pricing cold-chain projects in Pakistan. Walk through four steps — project basics, envelope, refrigeration, results. Engineer validation required before any quote is issued to a customer.
Rough estimate ±20%. Final pricing depends on site survey, refrigerant choice, component pricing on the day, and customer scope.
Where is the project, what are you storing, how big, and at what temperature?
Choose your FireSafe PIR panel thickness, site class, and structural envelope type.
Select refrigeration architecture, CA store extras, and power backup scenario.

Rough estimate. Final pricing depends on day-of refrigeration component pricing, current panel coil rates, civil scope refinement after a site survey, and customer-specific commercial terms.
| PEB (steel-frame) | RCC (concrete) | |
|---|---|---|
| Capex | 1.00× (baseline) | 1.35× (+35%) |
| Lead time | baseline | +6 weeks |
| Structural life | 25–35 years | 40+ years |
| Thermal mass | Low | High |
| Fire resistance | Standard | Higher (concrete shell) |
| Best for | Most cold-chain projects | Permanent owner-occupied flagships |
| Diesel genset | Solar PV | |
|---|---|---|
| Capex | — | — |
| Annual cost / saving | — spent | — saved |
| Payback | n/a (recurring fuel) | — |
| Resilience to load-shed | High (instant) | Medium (needs battery for night) |
| Fuel-price risk | High (PKR/litre fluctuating) | None (sunlight is free) |
Indicative numbers above are calibrated against Izhar Foster's project order book and Pakistan-specific benchmarks. Engineers reply within 24 hours.
Engineering + financial + commercial — combined for the first time in any cold-chain tool.
Heat-load estimation per ASHRAE Refrigeration Handbook Ch. 24 method, with Pakistan-specific MT 2.0%/K and LT 2.7%/K condenser ambient derate baked in.
Panel area sized from cold-room geometry, costed against current Izhar Foster pricing for 50–200 mm cores. Civil per site class (greenfield / inside-shed / multi-zone).
CDU / multi-DX rack / NH₃-glycol indirect / NH₃-DX. Each architecture has a different PKR-per-HP rate. We integrate Bitzer compressors, Heatcraft racks, LU-VE evaporators.
Sliding insulated doors for chillers and cold stores; high-speed Hörmann-class doors for high-traffic 3PL docks; heated-frame blast freezer doors for sub-zero.
Per-city load-shed defaults, OGRA diesel rate, NEPRA-approved rooftop solar capex. We show OPEX both ways and compute solar payback in years.
The metrics buyers actually want for board approval. PEB vs RCC envelope economics on the same page.
