Rubitherm Organic PCM Thermal Wax
800 kg of non-toxic organic phase-change material freezes during the day and holds a steady +2.4°C for 72 hours without electricity.
Runs on Sunshine
100% direct solar drive — completely decoupled from electric grids.
0 Chemical Battery Burden
Eliminates costly lead-acid/lithium battery replacement cycles.
0 Routine Diesel Reliance
Zero expensive fuel deliveries, generator maintenance, or emissions.
72-Hour Thermal Hold
Rubitherm Organic PCM thermal wax holds cold through prolonged rain or clouds.
02 / Commercial Loss & Profit Engine
Turn uncooled spoilage into retained profit.
Model the financial crop volume lost between field harvest and market. Adjust volume and wholesale value to calculate net retained profit after the flat $1,250/mo CaaS lease fee.
Calculation Breakdown Formula:
1. Uncooled Loss = Volume (50,000 kg) × 30% Baseline Spoilage Rate × Wholesale Price (€0.60/kg) = €9,000/mo
2. Net Retained Profit = €9,000 Gross Loss − €1,250 CaaS Lease = €7,750/mo
Net Retained Monthly Profit
+€7,750/ month
Standard Public Reference Case Study
For a aggregate hub moving 50 metric tons of fresh produce monthly at a standard €0.60/kg value baseline:
- STEP 01
50 MT / mo
Volume throughput @ €0.60 / kg
- STEP 02
€9,000 / mo
Uncooled baseline 30% spoilage loss
- STEP 03
€1,250 / mo
Flat CaaS monthly lease fee
- NET RESULT
+€7,750 / mo
Net profit retained (+€93,000 / yr)
03 / Infrastructure & Engineering
Sunshine by day. Stored cold at night.
Standard solar refrigeration relies on expensive chemical battery banks that fail in tropical ambient heat. Solvinter stores energy thermally using latent phase-change wax.
1. Daytime Solar Direct Drive
Roof-mounted 6.4 kWp photovoltaic panels deliver direct current power straight to variable-speed compressors, running cold cycles during peak sunlight hours.
2. Latent Thermal Storage
Excess solar capacity freezes 800 kg of non-toxic Rubitherm Organic PCM thermal wax integrated directly inside the container wall insulation envelope.
3. 72-Hour Autonomous Backup
When night falls or heavy cloud cover sets in, the frozen wax absorbs ambient ambient heat, holding temperatures at +2.4°C for up to 3 days without electricity.
