CAREL USA was founded in January 1990 as DGH Systems. DGH Systems distributed Carel Humidification systems and Air Conditioning Controls in the United States from their manufacturing plant located in Lancaster, PA.

In 2000, DGH Systems became part of the Carel Group and was renamed Carel USA, LLC. The company continues to produce Humidification systems and distribute Air Conditioning Controls and has become a leading player in the North American HVAC market.

In need of space to accommodate their continued growth, Carel USA bought 11 acres of land in Manheim, PA (20 minutes north of Lancaster, PA) in December 2004 and built a new 40,000 square foot facility. Shortly thereafter, the company entered the Refrigeration Controls market and began to promote Carel electronic controls in North America. In 2008, the internal quality system was audited and formally certified as per ISO9001:2000 Quality Standards.

While Carel USA continued to expand its manufacturing and engineering capabilities, it also expanded its reach to a broader range of HVAC and Refrigeration customers with a more widespread sales network. Regional representatives and factory employees are located throughout North America and work together with our customers to contribute to their success.

Today, Carel USA continues to lead the market with innovative products that are built on sound quality standards and that help customers achieve superior performances while limiting energy usage and reducing CO2 footprint.

The CAREL Group has a history of over 35 years in the production of humidifiers and controllers for HVAC/R applications. The group is headquartered in the Italian industrial heartland of Brugine (Padova). As of December 2009, The CAREL Group employs more than 700 employees in 14 commercial subsidiaries and four manufacturing plants worldwide.
