COLD CHAIN
SOLUTIONS

End-to-end cold chain design and installation for food processing, pharmaceutical, logistics, and retail. Blast freezers to −45°C, WHO-GMP validated pharma stores, and full IoT monitoring.

── What We Deliver

PRECISION
COLD CHAIN
FROM FARM TO PHARMACY

Cold chain failures cost the Indian economy billions every year in food waste and pharmaceutical spoilage. We design and build cold chains that hold temperature — from +8°C controlled pharmaceutical stores to −45°C blast freeze tunnels — with IoT monitoring and WHO-GMP validation where required.

── What We Offer

WHAT WE DELIVER

Cold Room Design

Insulated panel specification, floor loading, anti-condensation door heaters, emergency alarms, and glycol floor heating for freezer rooms.

Blast Freeze Tunnels

High-velocity air blast freeze tunnels achieving −35°C product core temperature within 90 minutes, designed to IQF and individual portioning standards.

Pharma Cold Rooms

WHO-GMP and SCHEDULE M validated cold rooms for vaccines, biologics, and API. Mapping studies, SOP documentation, and qualification protocols provided.

IoT Temperature Monitoring

Wireless sensors with cloud dashboard, real-time SMS/email alarms, automated excursion reports, and FDA 21 CFR Part 11-compliant data logging.

Refrigeration Plant Rooms

Central machine room design with N+1 compressor redundancy, automatic changeover, oil separators, and sub-cooled liquid receivers for long pipe runs.

Natural Refrigerants

R290 (propane) and R744 (CO₂) systems for zero global warming potential — future-proof against HFC phase-down and increasingly preferred by FMCG customers.

── FAQ

COMMON QUESTIONS

What is the difference between a cold room and a blast freezer?

A cold room maintains a set temperature (e.g. −18°C) for long-term frozen storage. A blast freezer uses high-velocity air to rapidly reduce the product core temperature from +20°C to −18°C in 90–180 minutes, preserving cell structure and quality. Both can be in the same facility.

What does WHO-GMP validation involve for a pharma cold room?

It involves Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ). This includes temperature mapping studies at multiple ambient conditions, sensor calibration certificates, SOP development, and a formal Validation Report. We provide full documentation packages.

What is the best refrigerant for a new cold room installation?

For new systems we recommend R449A (a drop-in HFO blend replacing R404A) or R290 (propane) for smaller systems. R290 has zero global warming potential and excellent thermodynamic properties but requires ATEX-rated components. We advise on refrigerant selection based on system size, location, and regulatory outlook.
