Introduction from Australia

[Andy McGill]

G'day to you all.

I am Andy McGill and I live in Sydney, Australia.

I have been an electronics technician in most fields for the past 35 years. The past 9 years I have been involved in medical, mainly with hospitals. This involved repairing and servicing medical equipment including medical gases.

In a weeks time I will be starting with Lomb Scientific. This will involve setting up a workshop and repairing their scientific research equipment. One of their products is Nuaire ultra low freezers. Even though I consider myself capable, I am unable legally to repair the gas circuits.

I am after as much information as I can get on cascade (dual stage) refrigeration. I am also seeking the services of an experienced engineer in this field.

Regards
Andy McGill
