PTR Baler & Compactor is proud to service Phoenix and the surrounding area. Our industrial and retail clients in Arizona rely on us or their waste management needs. We sell and service vertical balers, waste compactors and rebuilt vertical balers. Phoenix, the capital of the state of Arizona, is the state capital with the highest population, and the fifth most populous state in the country. The city began as an agricultural community in 1867 before becoming the capital in 1889. The climate in Phoenix is that of a hot desert, as it is located in the northeastern area of the Sonoran Desert. Today, Phoenix serves as a cultural center of Arizona and the headquarters of many high-tech companies.
