The 55PP is Ronco's 55 gallon open top cylindrical tank in polypropylene, molded in natural translucent resin so the liquid level reads through the wall. It measures 22-1/2 in. diameter x 34 in. tall, one-piece rotomolded with a flat bottom and an open rim, for mixing, soaking, rinsing and batch staging. Polypropylene takes higher service temperatures and a wider chemical range than polyethylene. A matching molded cover is listed separately as 55COVERPP. Fittings are installed per order.
