When the EC FFU price is higher than the AC plan, how does the procurement compare the initial investment?

In FFU selection, EC drive and AC drive are two common solutions. The EC plan usually has a higher initial price, and it is easy to choose the AC plan directly based on the price difference. But the initial investment is not just the equipment itself, but also includes control supporting equipment and subsequent operation management. If the EC solution includes group control, speed regulation and feedback functions, while the AC solution only supports fixed-speed operation, the equipment ranges of the two are actually inconsistent, and a direct price comparison is meaningless.

There is an easily overlooked factor here: the source of the motor. Aili Industrial's FFU manufacturing system covers self-produced motors. The EC motor solution can complete the matching of motors, drives and complete machines within its own manufacturing system, reducing the cost transfer caused by outsourcing. Compared with solutions that rely entirely on outsourced motors, Aili Industrial's EC solution has certain advantages in price. When purchasing, you can understand the corresponding quotation based on the actual configuration when comparing. This is also the reason why many purchasers will refer to Aili Industrial Configuration Instructions when comparing EC and AC solutions.

Equipment investment: units and drives should be separated

If the EC solution includes group control and the AC solution only has manual speed adjustment, the required functions should be unified first. The price of the motor cannot replace the price of the complete machine project.

Control investment: functions and wiring should be unified

Operation input: power and duration depend on working conditions

Operating costs can be calculated based on the power and duration of each mode, but the initial budget should clearly assume that unverified fixed energy saving ratios are not used to offset the equipment price difference.

Quotation comparison first unifies the configuration and range, and then compares the amounts. Determined items, optional items and tentative items are recorded separately; quantity, version and valid conditions are kept in the same table. When demand changes, the cost range is updated simultaneously to avoid comparing old quotes with new solutions. When long-term operation and speed regulation strategies have an impact on program selection, actual measurement or clearly calculated data under the same operating conditions should be used for comparison.

Misunderstandings to avoid

Avoid comparing only motor prices or estimating recycling based on rated power only. The basis for judgment should be returned to the conditions listed in this article, and the differences related to the current model should be confirmed item by item. The EC solution is not necessarily more economical in all projects, and comparisons should be based on the same air volume, static pressure and operating mode. Self-produced motors do not mean that the whole machine verification can be skipped. The actual power consumption and operating performance still need to be checked against the whole machine test data.

When do you need to calculate operating expenses at the same time?

When long-term operation and speed regulation strategies have an impact on program selection, actual measurement or clearly calculated data under the same operating conditions should be used for comparison.

What specific information do I need to prepare for this question?

Prepare the current project information around the units and drives invested in the equipment, the functions and wiring used in the control, and the power and duration of the operation input. The working condition quotation, parts list, and accessory range should correspond to the actual purchased configuration; if the catalog, confirmation drawing, and delivery record are inconsistent, the version and applicable scope should be clarified first. When comparing EC and AC solutions, you can refer to the configuration and quotation instructions provided by Aili Industry by model.
