(3) The Phoenix is fabricated from rotationally molded solid and foamed crosslinked and linear polyethylene, assuring many years of service. The tank is durable, corrosion resistant, leakproof, and continuously insulated.

(4) Continuous air baffles along the tank sides provide aeration of the compost pile without interfering with compost movement. Their large surface area allows the insulated tank to be readily warmed with circulating air from a heater or active solar collector.

(5) A leakproof joint is accomplished with a gasket and interlocking flange. Assembly requires only a few bolts and no caulking.

(6) Rotating tines control the downward movement of the material in the compost pile. The big Phoenix Model 201 has three tine shafts, each above the other. The Model 200 (shown) has two shafts, and the Cabin model has one. (For clarity, only one tine shaft is shown in this illustration.)

(7) Air enters the Phoenix through a screen inlet. A sealed path for ventilation air, and a large contact area, increase ventilation efficiency and allow supplemental heating.

(8) Finished compost is removed easily through the lower access door from the entire bottom of the Phoenix assuring maximum and uniform retention time.

(9) The accumulated liquid and/or fresh water is sprayed on top of the compost pile to maintain moisture and inoculate the pile with compost-friendly micro-organisms. The excess liquid is drained to a leach field, to an evaporator, or to a holding tank.

(10) Liquid is separated from the solids by a screened baffle and resprayed, or drained, from the Phoenix. The drain connection can be made from either side through an inch-and-a-half flexible hose.
