Dual-zone cooling tech
TwinDrive tech

Transform your absorption fridge into a smart, off-grid, dual-zone system with TwinDrive Cooling™ and QuadPhase Power™.

TwinDrive Cooling™

Two independent cooling circuits – fridge + freezer – for precise temperatures, flexible modes, and real efficiency on the road.

True dual-zone

Different temps per compartment. No compromises.

Flexible modes

Freezer-off in winter, dual-fridge for volume, or fridge→freezer swap.

Energy-optimal

Less icing, fewer cycles, longer autonomy when a zone is off.

Clean retrofit

Rear-mounted kit – cabinet, insulation and fascia stay intact.

QuadPhase Power™

Power from multiple sources – 230V shore, solar, alternator, and a compact LiFePO₄ 500Wh battery – for true off-grid autonomy.

  • Base: 500Wh LiFePO₄ (≈40Ah) + 200W solar → typical day covered.
  • Scale solar to 300W for heat waves/heavy use.
  • Driving boost: 30–50A for 1h ≈ 0.36–0.60 kWh back.

Off-grid Electrical Panel

Solar, alternator and lithium integrated with proper protections to power the fridge and other 12V loads – foundation of QuadPhase Power™.

  • Alternator charging with start-battery isolation.
  • MPPT for maximum harvest; safe distribution.
  • Scalable: base 500Wh LiFePO₄; solar 200→300W.

Why it matters – quick numbers

Typical estimates for temperate weather; tune to your rig. Bars/lines animate on scroll.

Daily running cost

~€2.20/day propane (absorption). ~€0.14/day 12V on shore (0.45 kWh @ €0.30/kWh). €0/day when solar covers demand.

Propane 12V AC Solar

Battery autonomy (200Ah @ 12V)

12V compressor typical draw ~ 35–45W avg. With sun: near-continuous. No sun: typically ~2–4 days depending on ambient & usage.

Driving tops you up

Alternator charge: 30–50A for 1h ≈ 0.36–0.60 kWh back – often enough for the next day's cooling.

FAQ

Clicks but won't light – where do I start?
Check ignition/PCB and supply. Quick map here: fault codes.
Eyebrow panel dead – any alternative?
Verify flat-cable and part numbers. If obsolete, see Universal Power Board.
Is a 12V compressor retrofit worth it?
For stability and no gas: yes. See the retrofit.
