maximum energy and cost savings installed cost savings ty p i cal bui ldi ng load pr ofi le Most systems operate at less than 60% capacity 90% of the time or more. Design Envelope pumps are built for high efficiency operation at part load energy savings Traditional pumps are designed for high efficiency operation at full load. Demand-Based Operation Design Envelope solutions reduce pumping costs through variable speed, demand-based operation — consuming only the energy required, based on current system demand.

sensorless technology Equipped with Sensorless technology, Design Envelope solutions do not require an external sensor to monitor and control the hvac load. traditional external sensor building height accurately track power & speed tracking power & speed In a chilled or heating water system, a building’s temperature controls influence the local flow of control valves that modulate the flow to the coils (load). As the control valves open for more water flow, the differential pressure across the valve decreases. The controller reacts to this change by increasing the pump speed. If the control...

parallel sensorless saving opportunity The traditional approach to control in a multipump installation involves staging pumps on the basis of motor speed. pspc technology stages pumps based on operating efficiency rather than motor speed and improves the efficiency of the full pump array by up to 30% over traditional multi-pump installations. speed-based staging head Parallel Sensorless Pump Control* (pspc) is a patented technology that improves the efficiency of a multi-pump installation through optimized load sharing. Staging pumps at any other point forces the pump array to operate at...

redundancy and savings with parallel pumping Because hvac pumping systems mostly operate at part load, a design using 2 or more smaller pumps is more efficient than one larger pump. In a 2-pump system, if one pump fails, the remaining pump can capacity split serve the system requirements with about 70% flow redundancy. The capacity split can be adjusted based on the building type and duty requirement. flow redundancy duty typical requirement applications generic duty schools, apartments, condos high sensitivity hotels, offices, outpatient clinics mission critical blood banks, hospitals,...

flow informs Design Envelope Pumps monitor flow so accurately they function as a flow meter. Industry standards recommend balancing system flows to ±10% accuracy. Design Envelope Pumps ≥ 2 hp (1.5 kw) deliver accuracy of ±5%. • • • • Highly accurate and reliable - no issues with fouling, so no need to service or re-calibrate Low installation cost - easy installation for retrofits Integral to pump - no additional space or wiring required Energy savings - accurate flow data informs optimization of an entire hvac system For evaluating an hvac system, just two flow values and four temperature...

optimized efficiency and performance active performance management learns predicts optimizes e d u c a t i o n With Active Performance Management at the plant level, you can save up to annual operating cost Active Performance Management is a systems management approach that optimizes hvac systems at any stage of a building’s life-cycle by continually learning from a broad network of installations and responding to changing hvac requirements. The combination of smart commissioning with real-time alerts and system transparency addresses performance drift and maintains occupant comfort
