LETTERS TO THE EDITOR
INCORPORATING COLD CHAIN
GOOD FOR THE ENVIRONMENT
My contention is that disposables are in fact
more environmentally friendly than refillable
cylinders for the following reasons:
1. We have been importing disposas for over
10 years and have never had a single
cylinder with suspect refrigerant. One of
the reasons for this could be that we have
a fixed supplier. Our success rate on refilled
cylinders has not nearly been as good. We
have encountered moisture problems not
too infrequently, dirt in the refrigerants, faulty
cylinder valves, and faulty pick-up tubes, to
name a few.
2. Disposas returned to us are usually
completely depleted of refrigerant.
Refillable cylinders invariably have a ‘heel’
leftover. Is all of the ‘heel’ recovered,
analysed, and then cleaned?
3. When a cylinder has a leaking valve, the
environment is affected. When the valve
is locked and cannot be opened, what
happens to the refrigerant?
48
4. Empty disposable cylinders are easily
recycled at scrapyards.
I urge all role players — that is, contractors, plant
operators, wholesalers, importers, and service
providers — to let their voice be heard before
the entire refrigerant market is captured and
dominated by a few. The dire consequences of
a disposa ban will include higher unemployment
and increased service charges, at a time when
our economy is already struggling.
Do you support the call for a ban or not?
