SC/SC-FC-HVAC system
结构型式
Digitally controlled, variable Smart control systems for driving glandless and glanded pumps of all makes and single and multi-pump systems. SC version: Control of fixed speed pumps via contactors (cascade connection). SC-FC version: Control of fixed speed pumps via contactors (cascade connection), but control of a pump via frequency converter as a base-load pump, control of the peak-load pumps in cascade connection
应用
For continuous power adjustment to the variable operating states of single, twin-head or multi-pump systems (up to 4 pumps). Controlling depends on the differential pressure Δp, feed/return temperature (±T) or differential temperature (ΔT), including the free adjustment of the duty point by means of preadjustment of the full-load pump output.
