Want to prevent Joule heating equipment from stopping due to voltage drops

What is the best proposal for manufacturers who have given up and said, "It can't be helped"?

Food processing manufacturer, Company S (approx. 200 employees)

Problem

Power problems such as instantaneous power loss (*), which occurs several times a year, often cause plant line stoppages. When food processing equipment stops, a great deal of man-hours are required before the equipment can be restarted, including cleaning and sanitizing the equipment, in addition to discarding food in the process of production.

I want to prevent the Joule heating system from stopping due to instantaneous low temperature, but I don't know what to do...

Company S is a food processing company that manufactures jams and fruit sauces. For a long time, the company had been suffering from a problem in which the Joule heating equipment used in the sterilization process of the production line stopped due to instantaneous low temperature.

When the Joule heating equipment in particular stops, the food products in the production line must be discarded because complete heat sterilization is not possible. Also, when the sauce cools and hardens, the machine becomes clogged, resulting in extensive work to clean the equipment, sterilize it, and restart it. This can lead to shipping delays. In particular, instantaneous low temperatures are often caused by lightning strikes, and trouble during the peak season from spring to summer not only inconveniences our customers but also leads to a credibility problem for our company." (Mr. A)

However, Company S did not know what to do about the instantaneous low, and had given up on the idea that it was "inevitable.

We have been experiencing instantaneous low sales since the beginning of this year, resulting in a large amount of food loss due to waste. Employees have been working holidays and overtime to compensate for the loss, but we knew that it would be a heavy burden to continue to do so every time in the future, and that we needed to take countermeasures. But we couldn't think of a good solution, so we gave up." (Mr. A)

*Instantaneous voltage drop (instantaneous voltage drop): A phenomenon in which voltage drops for 0.07 to 2 seconds due to a breakdown of a power transmission line or the like.

assignment
  • I want to prevent the Joule heating system from stopping due to instantaneous low temperature.
  • I don't know how to counteract the instantaneous low.

Solution

"SANUPS C23A" Voltage Dip Compensators can provide stable power supply without interruption during voltage drops.

Mr. A, who was worried about issues at his own factory, stopped by SANYO DENKI CO., LTD. booth at an exhibition and asked for advice on countermeasures against momentary voltage drops in Joule heating equipment.

The SANYO DENKI CO., LTD. representative who consulted Mr. A listened to his concerns in detail and proposed the SANUPS C23A Voltage Dip Compensators.
"I knew that UPS was used for computers and servers as a power backup device, but I had never thought of using it for large-capacity equipment such as food processing equipment. It provides a stable supply of power without any interruptions, even during momentary drops, so I thought it would be possible to prevent our joule heating equipment from shutting down." (Mr. A)

Requires only half the space of a UPS with the same capacity

"There are UPS and Voltage Dip Compensators to deal with voltage drops. Because the cause of this problem was only a voltage drop, we looked at Voltage Dip Compensators are specifically designed for voltage drops. There was almost no extra space in the factory, so we were worried whether the equipment would fit, but the SANUPS C23A Voltage Dip Compensators is about half the size of a UPS with the same capacity, so we were able to install it. Furthermore, the power storage device is not a lead battery, but a long-life electric double-layer capacitor, so we were reassured by the fact that it is maintenance-free and does not require part replacement for 10 years." (Mr. A)

Mr. A was satisfied with the proposal and immediately decided to introduce Voltage Dip Compensators" SANUPS C23A."
"We had given up on solving the problem of voltage drops in our Joule heating equipment, but SANYO DENKI CO., LTD. came up with the optimal solution after fully understanding our issues. We are very grateful." (Mr. A)

effect
  • SANUPS C23A Voltage Dip Compensators can supply stable power without interruption during voltage drops.
  • Compared to a UPS of the same capacity, it can be installed in about half the space.
  • No battery replacement required for 10 years, contributing to maintenance-free operation.
