The Stratos circulators are electronically controlled high-efficiency commercial wet-rotor circulators designed to avoid formation of condensate in sensitive areas. They can be used as part of cooling water systems for air conditioning and industrial refrigeration as well as heating. With the help of ECM technology, this HVACR pump reduces annual power consumption by up to 80 percent, said the company. The IR-monitor can optimize the circulator’s operational parameters. Using the Windows Mobile® platform and PDA device, it is possible to retrieve load diagrams, operating hours, logs, and other items. All essential functions of the circulator can be controlled by means of a single red button. Features include an impeller with 3-D curved blades and a smooth surface, and a rotor designed for speeds beyond 4,000 rpm.
