KM 311 fans.

E. CONCLUSION Fan design parameters are clearly indicated in the technical datasheet supplied with every fan. They

must be noted carefully when planning an installa�on. It is possible to retrofit fans and achieve

significant power savings which eventually impact the revenues of the company by reducing

maintenance costs as well. Customer has expressed sa�sfac�on with the results and plans further

interven�ons to op�mise plant performance and profitability.

A. ISSUE

Customer wanted to op�mise power consump�on in the factory . They requested for a site audit in areas of high power consump�on.

C. ACTION

The customer decided to take up retrofit of two fans to assess the savings in power as well as op�mise machine performance which were crea�ng high suc�on pressure and consuming almost full load current for the actual requirement of Air Volume and Suc�on pressure. Customer was presented with the data and a life cycle cost analysis for a retrofit installa�on that would be aligned with the machine working condi�ons. Customer agreed with the solu�on offered and installed two

B. OBSERVATION

Customer was provided observa�on data, fan performance data, vibra�on report and bearing condi�on report along with sugges�ons.

All small fans connected to compactors with 4kw motor installed running without problem, except the ones fixed for lapformer suc�on. It was observed fans installed for lapformer machine were drawing high current and crea�ng much more pressure and controlling this heavy suc�on was difficult. controlling, Even a�er the fans were drawing 4kw.

FAN MANAGEMENT PLAN

FAN MANAGEMENT PLANOur FAN MANAGEMENT PLAN (FMP) has been carefully developed to provide a superior level

of service and reliability. Our fundamental understanding of fans developed during the design

and construc�on phase is illustrated in the FMP.

The aim of FMP is to reduce costs by improving efficiency. It creates equipment history

on which is based plans for retrofits and spare parts purchases thus avoiding unplanned

stoppages.

THREE LEVELS OF FAN MANAGEMENT

Our knowledge, experience and exper�se in fan construc�on and opera�on coupled with our

commitment to the Indian market makes the FMP the best tool to op�mise ownership costs.
