PTR Baler & Compactor is proud to service Denver and the surrounding area. Our clients in Colorado use our waste management products in the retail, industrial, warehouse and facility management fields. We have a vertical baler or trash compactor for each sector. The city of Denver, nicknamed the 'Mile High City' due to its exactly one mile elevation, is the capital city of Colorado and the most populous city of the state. The city lies to the west of the High Plains in the South Platte River Valley, with downtown Denver located only 12 miles from the foothills of the Rocky Mountains. Denver has been one of the fastest growing cities in the United States.
