Dear Max:
I'm Carlos from MTF LTDA., Concepcion. I was thinking in your trial for pico-hydro set for low income peasants in the northern chilean Patagonia since a lot of time, but the long distance is a trouble for marketing in site planning. Minimun qty. for low price sets is a must looking for good import discounts. I can offer Turgo or Pelton sets from APR PowerPal www.powerpal.com as we are their representatives in Chile. I was in trouble for answer you because an updating Windows XP had thow away several mail adresses from my directory. I know chinese sets from Maqchin, Santiago, but not in practice. The technical specs. and data for those turbine sets are poor an too general for heigth, flow ranges, control, etc., for a safe application. Permanent magnet alternators can be used only for light en uses as lamps, TV and video sets, radio, and very small domestic electical powered devices; I think that refrigerator can't connected because the high starting current. Our experience with PowerPal is good with the low head MHG-LH sets for 200, 500 & 1000 Watts, permanent magnet alternators running at 1000 RPM. Water flow needed for those are 35, 70 and 130 l/s respectively for 1.5 m gross head. We have, installed by us, a MHG-1000 in the Quinquen Valley rural school (near Lonquimay) and works well since 1991. Perhaps will be good that we can both program a meeting in Puerto Varas for talk, face to face, about this interesting and very important and common task.

Typical parameters are 1-5 l/s and 30 to 100 m head. The equipment has to be low cost, low maintainance and robust, and involves a significant component of technology transfer to the rural dwellers who must be able to maintain their equipment. I have recently come upon the following chinese sets, who feature a permanent magnet alternator, a controller and a dump load (integrated in the base). http://www.maqchin.com/maqchin/pages/maquinaria_china_ltda_productos_centrales_hidroelectricas.htm models of interest are XJL 13-2 x 4.5 (750 W) and XJL 1 x 3.0 (3000 W) In the model I could examine, the rotor was a relatively crudely built (unpolished) turgo. The nozzle is huge and it is geared towards lower heights and bigger flows. I am trying to get the parameters of the rotational speed etc. * does someone have more data and a practical experience with those sets? lessons learned? * any experiences into adapting this equipment to higher heads/lower flows? Thank you, and best regards Max Klohn Puerto Varas, Chile Does your company feature in the microhydro business directory at http://microhydropower.net/directory ?
