I am trying to recall the name of a compressor maker in Australia.

They started out making open compressors I am not sure just how big they made them but I have seen ones up to 5 HP.

The compressors were used for both refrigeration and air conditioning.

Now comes the strange part, when hermetics were being use they converted their open compressors to what could loosely be called sealed units.

Not the conventional sealed unit as these compressors had a 'dome' covering the rotor and the windings were external fitting over the 'dome'

They used their basic open compressor but machined it to take the 'dome' to seal in the refrigerant, this 'dome' stuck out the side of the compressor with the winding covering it.

Hence if the windings burnt out the refrigerant was not contaminated.

Anyone remember these compressors?
