Mushroom Compost Unit Service
Mushroom compost units — bunker, tunnel & blower systems
- Bunker + tunnel design
- Pre-wetting & mixing area
- Centrifugal blower with flex pipe / manifold
- PLC / digital control panel
Typical applications
Operating Temperature
Tunnel: 45–60°C (phase-2)
Relative Humidity
Saturated
Engineering note
Bunker is open; tunnels are insulated with controlled airflow.
Technical Specifications & Construction
Every mushroom compost unit we build follows the same engineering discipline — sized to your load, not picked off a brochure. Specifications below reflect typical HyperCold builds.
- Panel thickness (tunnel)
- 100 mm
- Blower
- Centrifugal, high-static fan with VFD
- Flex pipe
- Insulated manifold with multiple drops
- Controls
- PLC / digital with temperature & RH probes
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.
Phase-1 vs Phase-2 vs Phase-3
Bunker handles phase-1; insulated tunnels with controlled airflow handle phase-2 (pasteurisation) and phase-3 (incubation).
Blower sizing
Critical for uniform aeration; under-sized blowers cause hot spots and uneven compost.
Cycle scale
20T and 30T are common starter sizes; commercial farms scale up to 60–100T cycles.
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.
- 01Cycle size (20T / 30T)
- 02Number of tunnels
- 03Blower capacity & VFD
- 04Control panel & PLC
- 05Refrigeration brand and capacity (TR)
- 06Floor type (PUF + chequered Al vs heated)
- 07Door type, ante room, electrical and DG backup
- 08Civil work and site readiness (Extra)
Why Operators Choose HyperCold
Engineered, not assembled
Heat-load, airflow, panel thickness and refrigeration sized for your commodity and site.
Line-item BOQ
Transparent panel, refrigeration, accessory, installation and AMC pricing — no lump-sum surprises.
Pan-India delivery
Manufactured at Sirsaganj, Firozabad; installed across India with regional service support.
Subsidy-ready DPR
Documentation aligned to NHB, MIDH, MoFPI, AIF and state scheme norms.
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
- Bunker + insulated tunnel design
- Centrifugal blower, VFD, flex pipe / manifold and PLC controls
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
- Raw material supply — wheat straw, chicken manure, gypsum (project-specific)
- Pre-wetting and mixing yard (civil)
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.
Under-sizing the blower
Compost needs uniform aeration; an under-sized blower creates hot spots and uneven phase-2 pasteurisation.
Starting compost before mushroom room is ready
Compost cycles run to schedule. If the production room is not commissioned, the spawn-run window closes and the batch is lost.
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 Mushroom Compost Unit 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 |
