Midwest Cooling Tower Services
Midwest Cooling Tower Services was founded on October 26, 1984 by Daniel A. Wiltz, Sr. The firm remains family-operated, with his sons Daniel A. Wiltz, Jr. and Paul E. Wiltz, P.E. now running daily operations. Its founding principle emphasizes safety as a condition of success. The core business is cooling tower repair and rebuild — a service the firm has performed for four decades. Midwest also supplies modular cooling tower rentals that can scale up or down based on client needs, conducts inspections for refineries and chemical plants, and stocks a substantial inventory of critical replacement parts. The company works with some of the largest companies in the world and serves multiple types of industrial clients. Midwest has not disclosed the number of its employees or its total revenue. The firm reports having zero OSHA recordable incidents in the past 32 years, a record it attributes to a safety culture that extends to its rental and inspection practices. The company also sells ErectaStep modular work platforms and crossover stairs. The firm differentiates itself through an operator-led governance model: the founder’s sons are engineers who run the business day-to-day, and the company has committed to growth without outside capital. Midwest is in an active growth phase, seeking top performers to expand its service capacity (per the firm, 2025).
