Anti-Condensate Controller Maintains Case Efficiency
Emerson Climate Technologies, Inc., has enhanced the Control Link Anti-Condensate Controller (ACC), an advanced controller for refrigeration case heaters designed to ensure anti-condensate heaters are activated only when necessary. The Control Link ACC is now equipped to control a larger variety of cases and provide compliance with the European Union's Restriction of Hazardous Substances directive. The new model also offers ease of installation with new quick connect terminals and a smaller physical size.

The Control Link ACC is used in full- and half-height glass door refrigeration cases. It modulates heaters to maintain a case's surface temperature just above the ambient dewpoint. This advanced level of control minimizes refrigeration case condensation and delivers up to 70% greater energy savings than controllers that rely on store dewpoint alone, sources report. Updates to the Control Link ACC also meet requirements for compliance with the Restriction of Hazardous Substances (RHS) legislation. The new, smaller size of the Control Link ACC allows it to be easily installed on a variety of locations, including the case’s doorframe and electrical runs. The Control Link ACC can be used as a stand-alone device, or as a component networked to Emerson’s Intelligent Store architecture, an integrated suite of products proven to improve maintenance, energy and operational savings. - Emerson Climate Technologies
