Hi all.

Im the happy new owner of a H575 that im about to gear up for some adventure.
Was wondering if anyone had any experience with equipping the H575 with an air compressor for filling divetanks and if so, what kind, electric, fuel driving, does and dont

All input is more than welcome.

Cheers.

Elgaard,

We have a dive compressor fitted on our 575. The compressor is made in Germany by Bauer and the model we have is a Junior 2. This delivers 100l/min so a 100 ltr scuba cylinder filled to 225 bar would take about 25 minutes to fill from empty. The Junior 2 is available as a 225 bar or 330 bar unit if you have very high pressure scuba tanks. Ours is fitted with a 2.2 kw 230V /50hz electric motor and the unit is fitted in the forepeak. We had Hanse fit a 16 amp power point in the forepeak so we could plug the compressor in. This is power point is connected to a 16 amp breaker on the 230v panel which is normally marked with "AUX". Note the standard "AUX" breaker is a 10 amp breaker so this needed to be changed. The wiring to the compressor power point needs to be 2.5 square cms or thicker to be able to supply the starting current draw without excessive voltage drop. The cost of a new Junior 2 is between E3,500 and E4,000 depending on options you choose. Our compressor can be run either by or generator or if the "airconditioning" shorepower in connected.

I hope this information helps you.

Thank you for your reply, ill have a look at the Bauer systems, sounds promising.

Was initially thinking about installing it in the dinghy garage, in the hull, port side, looks like a Bauer JR would it in there easy, and have easy access from the platform, any thoughts about that placement, any particular reason for you guys placing it in the forepeak ? 


Best Regards
Elgaard

Elgaard,

The dinghy garage is too wet/damp for a compressor with a 230v drive motor. The cockpit drains empty into this area as does the channel where the joint is for the fold up section of the deck to access the dinghy garage. When you wash the deck area you have water going down the drains, water coming in from the liferaft storage area and water coming in at the deck hinge joint. We put the compressor in the forepeak because it is a dry environment. Beside the dinghy we store things like spare fenders, standup paddle board paddles, spare fuel for the tender and spare mooring lines etc in the garage. With these things it does not matter if they get wet or are in a damp environment. Lastly you don't want the dive compressor air intake near the exhaust from the generator. Having the compressor in the forepeak the air inlet is at the furtherest point from the generator exhaust and if you are anchor it would generally be upwind also. I think you would also find that operating the compressor in the garage would cause the noise of the compressor to travel through the aft cabins and the saloon and cockpit and be a pain.
