Hydrovane 23u 415 to 240 options

[karll]

Having found a very nice Compair Hydrovane 23 for sale local to me i was wondering what options are there for 240 volt use .
I am hoping some of you have been through this and found a solution which is good on the wallet and reliable , from the research i have done there only looks to be 2 solutions -
1/ 240 to 415 phase converter which is very expensive and also another electrical device that will one day go wrong and cost a lot to repair .Although i would like feedback on these devices since they are new to me .

2/ get the old 415 motor re wired to suit 240 volt although will the motor have less power / torque therefore struggle to drive the air end .

Also how do you Hydrovane chaps get the compressor to fill a receiver then stop like a notmal belt driven piston job ?

I did look at the 17 pages of back history in this section but couldn't find an answer .


Many thanks for helping me out in advance .

there is no cheep and easy solution for your problem. there is a reason why 3ph kit is cheep as you really need 3ph to make it work or lots of money to get it to work! not totaly sure but you might find that the size of motor required to make it work single would have a huge power draw

Hello Karll,

not being familiar with the Hydrovane models, what is the power rating of the motor? If it is not too big then replacing the motor with a single phase equivelant is possibly an option? I would doubt if your three phase motor could be economically rewound to single phase. As a guide we recenty had a 0.75 Kw rewound and I think it was £120 + Vat, normally I wouldn't rewind such a motor but it was part of a stainless steel pump so it was economic to do so.
240V to 415v inverters are available but expensive, however, in some applications have advantages such as controlled start and stop characteristics, variable frequency (speed control) and do not require a starter, as they must not feed the load through one.

I was under the impression that Hydrovanes are run without using a reciever?

We used these in a place I worked before and they were connected to a couple of large receivers (silo size) when the receivers were up to pressure the compresssors went into a "unload" state, still running but using less power.

hydrovanes dont need a storage tank but it is beneficial to have one .cooler air and a constant volume and pressure on demand
