Energy efficiency is a hot topic today

Both customers and governements are asking energy
efficient solutions

Customers are focusing to they key processes

ABB motors and drives bring state of the art efficiency
features to market

How ABB and customer can together cool down this
hot topic?


Models of a system as complex as the global climate
cannot, of course, offer accurate predictions, but do at
least reduce levels of uncertainty.

Energy savings (TWh)
© ABB Oy - 13 -
•
•
The installed base of ABB drives saved about 130 TWh in 2006, equivalent to the
consumption per year of more than 32 million families.
ABB’s installed base of ABB low voltage drives reduced CO2 emissions in 2006 by 109
million ton, more than the yearly emission of Finland.

Energy audit

With energy audits customer
can achieve higher energy
savings thanks to ABB
competence

Optimizing customer process
together with ABB audit team
bring optimal results

Step 1 - Introduction

Meeting with customer responsible person – well known

Explain of scope of the audit

Explain the assistance he needs

Entrance to technology

Help with some special measurements

Step 2 - Information

Collecting the information
about audited technology

Selecting of applicable
drives (pumps, fans,
conveyors, blowers,..)

Rating plate parameters of
motors and driven
equipments
Step 3 - Measurements

Determination of actual
demand from technology

Measuring of electrical
parameters
voltage, current, power, power
factor,...

Measuring of process
parameters
pressure, flow, speed,
temperature,...
© ABB Oy - 18 -

Measurements are optional

Step 3 - Measurements

With actual measurements it
is easy to prove savings

Easy approach, one phase
current measurement

Example: Becker extract fan,
UK

Before, 68A average

After, 49A average
