3. Your Dulas Solar Direct Drive Refrigerator
Congratulations on choosing the Dulas VC30SDD vaccine refrigerator. With over 30 years of
engineering experience in the production of solar powered vaccine refrigerators, Dulas is
considered one of the market leaders in this field.
The VC30SDD is Dulas’ latest innovation in solar refrigeration. Using our new solar direct drive
technology we have replaced the traditional battery energy store with a ground breaking phase
change solution. With this new technology we can offer the same renown Dulas quality and
reliability that have always kept your vaccines safe, but in a simpler and more efficient package.
How does solar direct drive work?
When the sun shines the solar panels generate electricity which directly drives the refrigerators
compressor, cooling down the refrigerator and its contents. As a result the compressor only
operates during the day. To maintain the temperature at night or when the sun is not shinning the
refrigerator has a phase change lining. This interior lining holds the exact temperatures required
for safe vaccine storage and acts as a “cold store”, storing energy that keeps the temperatures
stable all day and night.
In order to store sufficient energy to keep vaccines safe for prolonged periods without any
sunshine, the refrigerator must be allowed time to charge it’s cold store. Under normal
sunlight conditions (8 hours/day of solar irradiance >250W/m²) the refrigerator will take
approximately 7 days to fully charge the cold store and be ready for vaccine storage.
Recommended solar array
The VC30SDD has been designed to meet the World Health Organisation’s Performance, Quality
& Safety (PQS) standards. The refrigerator has been independently tested to the PQS standard
WHO/PQS/E03/RF05 and is a Hot zone rated appliance with an ambient operating temperature
range of between +5C and +43C. For use in such Hot Zone environments it should be powered by
a minimum 260Wp solar array with a Voc not exceeding 45Vdc.

5. Material Safety Information
THE REFRIGERATOR
The Dulas VC30SDD conforms to the European directive 2002/95/EC on hazardous substances
and does not contain the following elements: lead, cadmium, mercury, hexavalent chrome, PBB or
PBDE.
The absence of ozone destroying materials is in accordance with EC 1005/2009 (CFC-free)
It is compliant with European Standards (CE) EN60335-1:2010 & EN60335-2-24:2010.
R600a refrigerant – Isobutane, is highly flammable when mixed with air. Do not inhale, ingest, and
avoid contact to skin. Ensure that any work carried out on the refrigeration circuit is done by a
competent refrigeration engineer.
THE PHASE CHANGE MATERIAL (PCM)
The refrigerator contains an organic phase change material (PCM) that provides the energy store
for the refrigerator. This PCM material is a paraffin wax that is liquid at room temperature and is
stored in large tanks secured inside the walls of the refrigerator. In normal use the user will never
be aware of its presence. This PCM is classified under regulation (EC) No 1272/2008 as a
category 1 aspiration hazard and is classified under regulation 67/548/EWG, 1999/45/EG as
having the potential to cause physical harm (R65 & R66). At normal ambient temperatures this
product will be unlikely to present an inhalation hazard because of its low volatility. At high
temperature aerosol/mist can cause an irritation of the respiratory tract.
H304 May be fatal if swallowed and enters airways.
P301 + P310 IF SWALLOWED: Immediately call a POISON CENTRE or
physician.
P331 DO NOT induce vomiting.
R65: Harmful: may cause lung damage if swallowed.
R65: Repeated exposure may cause skin dryness or cracking.
In the event of a PCM spillage:
Wear suitable protective clothing, gloves and safety glasses when clearing up spillages.
Use an absorbent substance such as sand to contain any escaping material.
Do not allow to enter drains / surface waters / groundwater. In case of the leakage of a large
amount inform the responsible authorities.
