[RE-wrenches] Vaccine refrigeration

[Steve McCarney]

hi

I agree that SunDanzer battery, free solar direct drive (SDD) fridges have
revoluntionized the solar vaccine fridge market. Two of their fridges are
WHO preqaulaified thrugh extensive testing that approvees a product for
sale through the UN.  If you need a freezer too then SunDaner has also
pioneered SDD freezers for immunization ice pack freezing.

If the health facility also needs some power for lights, fan and small
battery recharging (e.g.cell phone, laptop, fetal doppler) then check out
the B Medical Systes Health Center Kit that is approved by WHO to be
coupled to a B Medical SDD vaccine frdge (or SDD fridge freeer
combination).  WHO calls that category of products "Energy Harvesting" and
the control system always priorities the vaccine fridge power first and
then harvests the excess for user selected loads, about 500 Wh/day are
presently availalbe and more in the future is the hope.  If the energy
harvest control fails it does take down the fridge.
