Dynamatic: True System Efficiency
Capital Costs up to 65% less than VFD systems
Capital costs include application engineering, product procurement, system installation and commissioning. For typical VFD installations, added costs can occur in each of these areas due to system complexity and required additional components such as harmonic mitigation and system cooling compared to these highly complex variable frequency drive installations, especially in medium voltage pump applications, a new Dynamatic system can typically save municipalities from 50% to 60% on product procurement costs alone. Dynamatic systems now feature advanced, yet simple to use, digital control integration.
- Immediate savings of potentially $1M+ on first costs
- No additional costs for conditioning/cooling and harmonic suppression
- Lower cost installation and commissioning due to less complex systems
- Advanced yet simple to use digital control integration
- Electronics are 60-70% smaller than comparable medium voltage VFDs
- Unlike VFDs, medium voltage control occupies a very small footprint
Energy Costs lowest for wastewater pumping applications
The operating efficiency of a Dynamatic drive increases relative to the normal operating speed of a motor. This makes the Dynamatic drive ideally suited to most wastewater pumping applications, which typically require controlled speed within the range of from 75% to 100% of the motor’s rated speed. In contrast, the operating efficiency of a variable frequency drive decreases across this range. In addition, VFD operating efficiency can be further diminished by added energy costs incurred by required additional VFD system components.
- Most wastewater pumping application require 75-100% rated speed
- Dynamatic drives use less energy to operate in these applications than VFDs
- Unlike VFDs, you do not pay for required cooling and harmonic protection
- Digital closed-loop control uses less than 1% of the total AC input current to the motor
- Lower peak demand costs: no multiple, medium voltage motor starting and stopping
- No additional equipment energy consumption such as external cooling and harmonic mitigation
- Capable of continuous operation in 40°C ambient temperature
Ownership Costs greatly reduced maintenance, repairs and upgrades
For decades Dynamatic drives have outlasted variable frequency drives in a wide range of wastewater applications. In fact, Dynamatic drives have been shown to outlast VFDs by as much as 6:1. Their rugged and reliable electromagnetic clutch design is highly tolerant of fluctuations in power quality. Unlike VFDs, Dynamatic systems produce virtually no harmonic noise into your plant’s electrical system or onto the utility grid. By comparison, VFDs continue to be complex devices bearing higher ownership costs with shorter product life cycles. These significantly higher costs are attributable to quicker VFD product series obsolescence, faster parts obsolescence and earlier forced product replacements.
- Proven rugged and reliable electromagnetic clutch design
- System have outlasted VFDs by as much as 6:1
- Easy to maintain by on-site staff using low-cost parts
- Service and repair can often be performed by maintenance staff
- Unaffected by power quality fluctuations that can destroy VFDs
- Unlike VFDs, no annoying audible whine enters the work environment
- Produces virtually no harmonic distortion into your electrical system or power grid
