Only use for closed loop or constant flow applications Slow control can cause large variations in outlet temp. Only use for closed loop or constant flow applications Fast control valve reduces temperature variation to +/-5 C. Can still struggle with very big demand changes Fast control valve reduces temperature variation to +/-5 C. Can still struggle with very big demand changes The Brain controls to +/-1 C, with varying demands, recirculation needed The Brain controls to +/-1 C, with varying demands, recirculation needed Emech controls to +/-0.5 C, with varying demands, no recirculation needed Emech controls to +/-0.5 C, with varying demands, no recirculation needed Energy Efficiency Poor due to flash steam wastage. Greater losses occur with higher steam inlet pressures Condensate is sub-cooled to 90 C thus preventing flash steam loss Poor due to flash steam wastage. Greater losses occur with higher steam inlet pressures Condensate is sub-cooled to 90 C thus preventing flash steam loss Low constant inlet steam pressure of 1.0 barg keeps flash losses to a minimum Condensate is sub-cooled to 90 C thus preventing flash steam loss Low constant inlet steam pressure of 1.0 barg keeps flash losses to a minimum Condensate is sub-cooled to 90 C thus preventing flash steam loss Condensate Removal Requires the installation of a condensate pump in order to respond to changes in demand Requires the installation of a condensate pump in order to respond to changes in demand in most applications Constant steam pressure means no condensate in most applications Water Hardness and Scaling No issue with closed loop systems. Reduced temp in heat exchanger can reduce scaling problems Steam is in the tubes - will take longer to scale so reduced cleaning. Spring like coils resist scaling No issue with closed loop systems. Reduced temp in heat exchanger can reduce scaling problems Steam is in the tubes - will take longer to scale so reduced cleaning. Spring like coils resist scaling. Limited to 100ppm of CaCO3 or increased scaling may occur Reduced temp in heat exchanger reduces scaling. Spring like coils resist scaling.
