Let the 1900 VFD operate your buildings with greater efficiency; using them to control your pumps can significantly reduce energy costs.
Most HVAC systems are designed to keep the building cool on the hottest days and warm on the coldest days. Therefore, the HVAC system only needs to work at full capacity on the 10 or so hottest days and the 10 or so coldest days of the year. On the other 345 days, the HVAC system may operate at a reduced capacity. This is where a system with variable frequency drives (VFDs) can be used to match system flow to actual heating and cooling demands. The VFD can reduce the motor speed when full flow is not required, thereby reducing the power required and the electrical energy used.
The 1900VFD is part of Taco's eSmart family of products. More efficient use of energy for greater system efficiency and comfort are what e-smart products are all about. They're designed to reduce life -cycle costs and improve overall HVAC system performance.
Why Variable Speed Pumping?
- Better Performance
- More efficient method of pump balancing
- Better system balancing
- Lower noise in piping
- Better control prevents cavitation
- Eliminates valve blow by
- Allowance for expansion
- Interim Performance at part load can be optimized
- Longer equipment life
- Soft start/stop
- Rotating Equipment: Life = 1/speed
- Lower pressure on components
- Valve actuators absorb less pressure
- Lower "System" Life Cycle & Installed Cost
- Reduced maintenance
- Lower "In Rush" current reduces wire and circuit breaker size
- Smaller pipe (design 10-12 ft/sec)
- Less tonnage required in chiller plant
- Chiller plant optimization
- Less capacity goes further
- Better Delta Ts
