Limitrol+ combines various technologies into a responsive system that floats head pressure, saving energy and reduces environmental competitive systems, Limitrol+ combines variable speed EC motor technology, condenser portioning and vari-ous systems modifications to provide the ultimate in performance and control.

7 As a result, Limitrol+ functions in much colder ambients where previous systems have proven does it do? Conventional head pressure control systems maintain a constant head pressure regardless of ambient temperatures. Limitrol+ intelligently responds to ambient conditions to float head pressure without sacrificing system performance at lower temperatures. What are its applications? Condensing Units over 5 HP Ideally suited and most effective in applications with fluctuating ambients Perfect for installations where reduced refrigerant charges are desired or much can Limitrol+ save you? Reduces compressor energy consumption and run time EC motor technology further saves energy and reduces electrical requirements Lowered environmental impact through reduced refrigerant use Stable system performance in lower ambientsMODELP hiladelphia, PANew York, NYBoston, MACharlotte, NCAtlanta, GALos Angeles, CASt Louis, MOSt.
