MAIN PRODUCT DESCRIPTION
Used Luwa model NL3-300/2200/HT vertical thin film evaporator constructed of 316L stainless steel with approximately 21.6 square feet of heat-transfer area. The evaporating section measures 12 inches in diameter by 96 inches long and is divided into two sections. The internal chamber is rated for full vacuum at 365°F, and the jacket is rated for approximately 150 psi at 365°F. The evaporator features a 3-star Type L rotor, radial separator, conical bottom with a 2-inch-diameter product discharge, 12-inch-diameter vapor outlet, and mechanical seal. The rotor assembly is driven by a 7.5 HP belt-drive motor rated for 3-phase, 60 Hz, 230/460-volt service at 1,720 rpm. This used evaporator is missing its support ring, and buyers should confirm repair requirements, process suitability, capacity, product-contact specifications, and included components before purchase.
