Solar Direct Drive Ref. Zero
Solar Direct Drive Ref. Zero (Product Code: SLE/CCE/05) is a solar-powered vaccine refrigerator used to store larger vaccine stocks at health centres that must run their cold chain without grid electricity. Its 128 litres of net vaccine storage and R134a refrigerant make it a high-capacity SDD model, delivered as a complete plug-and-play installation with its matched solar power system. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for programme purchases and lab equipment tender requirements.

What Is the Solar Direct Drive Ref. Zero Used For?
The Ref. Zero is meant for facilities that keep a sizeable vaccine stock on site, such as a community health centre or a base that re-supplies several outreach points. Because it is a solar direct drive appliance, its compressor draws on the solar array rather than on a mains line or a generator, so the store can stay cold where grid power never reached or fails for long periods. A 128-litre compartment gives room to separate antigens and diluents in an orderly way instead of crowding a small unit.
The specification ties the solar power system to the appliance’s consumption, the local climate, ambient temperatures and a solar radiation reference of 3.5 kWh/m² per 24 hours. That reference is the design figure used to size the array, so give us your site location or sunshine data when enquiring; installers should then follow the technician’s manual for panel placement and wiring.
What to Specify When Ordering
- Number of refrigerators and the facilities they will serve.
- Confirmation that 128 litres of net storage matches your stock plan, or whether a smaller SDD model is preferred.
- Site location or solar radiation data, for comparison with the 3.5 kWh/m² per 24 hours sizing reference.
- Whether water-packs must also be frozen on site, since this specification lists no freezer section.
Supplier
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, based in Ambala, Haryana. For large solar refrigerators like the Ref. Zero, the company acts as the supplying partner: it sources the appliance with its solar power system, prepares quotations and arranges dispatch to buyers in India and international markets. Company background is available on the ScienceLab profile page.
Related Cold Chain, Solar & Communication Equipment
Health centres that run a 128-litre SDD store usually need these alongside it:
- Solar Direct Drive Frz. — a solar freezer for water-packs, as the Ref. Zero is a refrigerator only.
- Cold Box — for collecting bulk stock and carrying it to the store.
- 30 Day logger — to keep a temperature history of the refrigerator.
- Mains Ref 128L — the same net volume for sites with a reliable mains supply.

Frequently Asked Questions
How much vaccine does the Solar Direct Drive Ref. Zero hold?
The Solar Direct Drive Ref. Zero has a net vaccine storage volume of 128 litres. That capacity is aimed at health centres and supply points that keep a larger stock on site, rather than small posts that only need a compact refrigerator.
Is the Solar Direct Drive Ref. Zero the same as the Solar Direct Drive Refrigerator Zero?
No. They are separate models: the Solar Direct Drive Ref. Zero (SLE/CCE/05) is the 128-litre unit with R134a refrigerant, while the Solar Direct Drive Refrigerator Zero (SLE/CCE/06) is a much smaller refrigerator with a different refrigerant. Quote the product code when you enquire to avoid confusion.
What does the 3.5 kWh/m² per 24 hours figure mean for the Ref. Zero?
For the Solar Direct Drive Ref. Zero, 3.5 kWh/m² per 24 hours is the solar radiation reference used, together with power consumption, climate and ambient temperatures, to match the solar power system. Share your site’s location so the supply can be discussed against it.
Which refrigerant does the Solar Direct Drive Ref. Zero use?
The Solar Direct Drive Ref. Zero uses R134a refrigerant. It is specified for ambient operating temperatures between +5°C and +43°C with Grade A freeze protection, and technicians should follow the English technician’s manual for any refrigeration work.
Who supplies the Solar Direct Drive Ref. Zero?
The Solar Direct Drive Ref. Zero is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company prepares quotations and arranges dispatch for health programmes, distributors and institutions in India and international markets.
