How HyperCold Designs This Cold Room
These are the design factors we lock down before quoting. Skip any of these and the project either runs hot, drinks electricity, or under-delivers on shelf life.
Cascade refrigeration
For temperatures below −30°C, cascade systems are more efficient than single-stage.
Door & gasket selection
Heated door frame to prevent gasket freeze-stick and door sealing failure.
Site conditions
Ambient design, condenser placement and water supply heavily affect compressor sizing.
What Drives the Project Cost
We don't quote square-foot rates — every build is BOQ-priced. The factors below decide where your project lands within a realistic range.
- 01Cascade vs single-stage refrigeration
- 02Ambient design conditions
- 03DG backup capacity
- 04Refrigeration brand and capacity (TR)
- 05Floor type (PUF + chequered Al vs heated)
- 06Door type, ante room, electrical and DG backup
- 07Civil work and site readiness (Extra)

Scope split — what we deliver, what your site provides
Clear scope upfront avoids the most common project-cost surprises. Items marked "subject to" are finalised after technical site evaluation.
HyperCold scope
- Heat-load and refrigeration sizing (BOQ-based)
- PUF panel manufacturing at our Firozabad plant
- Refrigeration unit supply, piping, charging and leak test
- On-site panel erection, door fitting and commissioning
- Control panel, sensors and data-logger (where applicable)
- Operator handover, AMC kick-off and warranty documentation
Client / site scope
- Civil work — floor, walls, foundation, plinth (subject to final site inspection)
- 3-phase electrical supply up to the project room (load to be confirmed after technical evaluation)
- Earthing pit, MCB / RCCB at the LT panel side
- Water supply for installation and cleaning
- Site access — crane / hydra movement, internal pathway and unloading zone
- Any local permissions (fire NOC, FSSAI, pollution clearance) — subject to scheme guidelines
Common mistakes we help clients avoid
Most of these surface only after commissioning, when fixes are expensive. Catching them at quotation stage protects both shelf life and capex.
Using freezer-room specs for deep freezer
−25°C to −35°C needs thicker PUF, stronger compressors and a different defrost strategy. A freezer-room spec will simply not pull down.
Assuming ambient design = 35°C everywhere
Many Indian sites peak above 45°C. Sizing on a low ambient leaves the unit incapable of holding setpoint in May–June.
Under-sizing electrical supply or skipping DG backup
Cold rooms run year-round. A weak LT supply or no DG plan turns every grid outage into a spoilage event.
Treating subsidy as a guarantee
Subsidy eligibility depends on project type, beneficiary category, scheme notification and department verification. Plan financials independent of subsidy approval.

How HyperCold Deep Freezer Room compares
Indicative comparison between a typical local fabricator approach and an engineered HyperCold build. Final scope is confirmed after site inspection.
| Build factor | Typical local fabricator | HyperCold engineered |
|---|---|---|
| Sizing basis | Square-feet thumb rule | Heat-load worksheet per commodity & ambient |
| Panel & skin | Generic PUF, mixed skin | PPGL / GI both sides, 40 ± 2 kg/m³ PUF, cam-lock |
| Refrigeration | Locally sourced, no brand commitment | Daikin / Bitzer / Emerson — sized to TR |
| Documentation | Single-line quote | Line-item BOQ + DPR aligned to subsidy norms |
| Controls & data | Mechanical thermostat | Carel / Danfoss digital with data-logger |
| Handover & AMC | Verbal warranty | Written warranty, SLA-backed AMC, spares planning |
