1. Eco 8, Practical intelligence
Energy saving simulator with Altivar

2. Eco 8 estimates your energy savings in pumps & fans applications
By adding a speed drive in your installation instead of electromechanical flow control
Taking into account all datas of your installation
As the energy efficiency for fan or pump systems depends on the control method used, a speed drive is especially efficient when the system is running with partial flow.

3. Eco 8 main benefits
The tool provides financial figures for assessing the profitability of purchasing ALTIVAR
Simulate the possible savings on your installations
adding a variable speed drive instead of electromechanical devices
Select the suitable Altivar product according to :
The mechanical and electrical datas
The duty cycle of your installation
Calculate how long it takes to get a return on your investment
Estimate how much reactive energy you could save

4. ECO 8 is not a contractual tool
The accuracy of the results is affected by the accuracy of the inputs datas.
Results should be used only for estimating purposes.
The results of this calculation program must not be used as the basis for guaranteed energy savings.

5. Customise your Eco 8 tool

6. Eco 8 allows you to describe your project
Define the project
characteristics
Select the
application
Define the electrical
characteristics
Define the air flow
or water flow
cycle time
Get the final
results and ROI

7. Step 1 : Define the project characteristics
Fill all the boxes

8. Step 2 : Select the application
Choose you market :
That will propose the right drive selection (ATV21 or ATV61)
Select
fan or pumping

9. Step 2 : Some advices on pump datas
With vane control, make the right choice according to your installation :
HMT : Pump head at 0 flow
Z : Total dynamic head = static head + friction head of installation
For transfert pump : Z ~ 0 (no static head)
For high elevation, the ratio is closed to 0,85

10. Step 3 : define the electrical characteristics
Choose the product protection :
IP20 or IP54
Select the voltage
Select the motor power
Current, cos phi, efficiency, price of electricity are filled automatically
(could be adjusted)
Select the price of total project

11. Step 3 : Some advices on installation price
You have to give a price evaluation to your customer, but …………..
you don’t know the price of installation !
One of the method could be :
Use the list price of the IP54 solution
This price could represent the drive + installation cost

12. Step 4 : define the operating time
Select the operating time
reference
Fill the right cells
for each flow rate

13. Step 4 : Some advices on cycle time
All the final results are strongly linked to the cycle time, but sometimes, the customer doesn’t know the real cycle time !
This software can give you only an estimation of the savings, that’s to say, to decide if it’s interesting to invest……
So, if you don’t know the cycle, you can propose 2 simulations :
One optimistic
One pessimistic
This is a simple way to limit the investigations

14. Step 5 : get the results Show the differences of energy consumption :
with or without speeddrive
Show reactive energy you could save with speeddrive
- avoid the use of capacitors bank
- reduce your energy penalties
Give the time of return on investment
(payback period, 1-2 years is acceptable)

15. Step 5 : Print your results
To be integrated in the commercial proposal (Word file)
To keep a record on your proposal
