How Mid-South Metallurgical cut Energy Use by 22%

Mid-South in Murfreesboro, Tennessee operates a high-energy plant providing precision heat treatments for high-speed tools – and also metal annealing and straightening services. This was a great business to be in before the energy crisis struck. That was about the same time the 2009 recession arrived. In no time at all the market was down 30%.

Investors had a pile of capital sunk into Mid-South?s three facilities spread across 21,000 square feet (2,000 square meters) of enclosed space. Within them, a number of twenty-five horsepower compressors plus a variety of electric, vacuum and atmospheric furnaces pumped out heat 27/7, 52 weeks a year. After the company called in the U.S. Department of Energy for assistance, several possibilities presented.

Insulate the Barium Chloride Salt Baths

The barium chloride salt baths used in the heat treatment process and operating at 1600?F (870?C) were a natural choice, since they could not be cooled below 1200?F (650?C) when out of use without hardening the barium chloride and clogging up the system. The amount of energy taken to prevent this came down considerably after they covered and insulated them. The recurring annual electricity saving was $53,000.

Manage Electrical Demand & Power

The utility delivers 480 volts of power to the three plants that between them consume between 825- and 875-kilowatt hours depending on the season. Prior to the energy crisis Mid-South Metallurgical regarded this level of consumption as a given. Following on the Department of Energy survey the company replaced the laminar flow burner tips with cyclonic burner ones, and implemented a number of other modifications to enhance thermal efficiency further. The overall natural gas reduction was 20%.

Implement Large Scale Site Lighting Upgrade

The 24/7 nature of the business makes lighting costs a significant factor. Prior to the energy upgrade this came from 44 older-type 400-watt metal halide fixtures. By replacing these with 88 x 8-foot (2.5 meter) fluorescent fittings Mid-South lowered maintenance and operating costs by 52%

The Mid-South Metallurgical Trophy Cabinet

These three improvements cut energy use by 22%, reduced peak electrical demand by 21% and brought total energy costs down 18%. Mid-South continues to monitor energy consumption at each strategic point, as it continues to seek out even greater energy efficiency in conjunction with its people.

FUJIFILM Cracks the Energy Code

FUJIFILM was in trouble at its Dayton, Tennessee plant in 2008 where it produced a variety of speciality chemicals for industrial use. Compressed-air breakdowns were having knock-on effects. The company decided it was time to measure what was happening and solve the problem. It hoped to improve reliability, cut down maintenance, and eliminate relying on nitrogen for back-up (unless the materials were flammable).

The company tentatively identified three root causes. These were (a) insufficient system knowledge within maintenance, (b) weak spare part supply chain, and (c) generic imbalances including overstated demand and underutilised supply. The maintenance manager asked the U.S. Department of Energy to assist with a comprehensive audit of the compressed air system.

The team began on the demand side by attaching flow meters to each of several compressors for five days. They noticed that – while the equipment was set to deliver 120 psi actual delivery was 75% of this or less. They found that demand was cyclical depending on the production phase. Most importantly, they determined that only one compressor would be necessary once they eliminated the leaks in the system and upgraded short-term storage capacity.

The project team formulated a three-stage plan. Their first step would be to increase storage capacity to accommodate peak demand; the second would be to fix the leaks, and the third to source a larger compressor and associated gear from a sister plant the parent company was phasing out. Viewed overall, this provided four specific goals.

  • Improve reliability with greater redundancy
  • Bring down system maintenance costs
  • Cut down plant energy consumption
  • Eliminate nitrogen as a fall-back resource

They reconfigured the equipment in terms of lowest practical maintenance cost, and moved the redundant compressors to stations where they could easily couple as back-ups. Then they implemented an online leak detection and repair program. Finally, they set the replacement compressor to 98 psi, after they determined this delivered the optimum balance between productivity and operating cost.

Since 2008, FUJIFILM has saved 1.2 million kilowatt hours of energy while virtually eliminating compressor system breakdowns. The single compressor is operating at relatively low pressure with attendant benefits to other equipment. It is worth noting that the key to the door was measuring compressed air flow at various points in the system.

Monitoring Water Banks with Telemetrics

Longstanding droughts across South Australia are forcing farmers to rethink the moisture in the soil they once regarded as their inalienable right. Trend monitoring is an essential input to applying pesticides and fertilisers in balanced ratios. Soil moisture sensors are transmitting data to central points for onward processing on a cloud, and this is making a positive difference to agricultural output.

Peter Buss, co-founder of Sentek Technology calls ground moisture a water bank and manufactures ground sensors to interrogate it. His hometown of Adelaide is in one of the driest states in Australia. This makes monitoring soil water even more critical, if agriculture is to continue. Sentek has been helping farmers deliver optimum amounts of water since 1992.

The analogy of a water bank is interesting. Agriculturists must ?bank? water for less-than-rainy days instead of squeezing the last drop. They need a stream of online data and a safe place somewhere in the cloud to curate it. Sentek is in the lead in places as remote as Peru?s Atacamba desert and the mountains of Mongolia, where it supports sustainable floriculture, forestry, horticulture, pastures, row crops and viticulture through precise delivery of scarce water.

This relies on precision measurement using a variety of drill and drop probes with sensors fixed at 4? / 10cm increments along multiples of 12? / 30cm up to 4 times. These probe soil moisture, soil temperature and soil salinity, and are readily re-positioned to other locations as crops rotate.

Peter Buss is convinced that measurement is a means to the end and only the beginning. ?Too often, growers start watering when plants don’t really need it, wasting water, energy, and labour. By monitoring that need accurately, that water can be saved until later when the plant really needs it.? He goes on to add that the crop is the ultimate sensor, and that ?we should ask the plant what it needs?.

This takes the debate a stage further. Water wise farmers should plant water-wise crops, not try to close the stable door after the horse has bolted and dry years return. The South Australia government thinks the answer also lies in correct farm dam management. It wants farmers to build ones that allow sufficient water to bypass in order to sustain the natural environment too.

There is more to water management than squeezing the last drop. Soil moisture goes beyond measuring for profit. It is about farming sustainably using data from sensors to guide us. ecoVaro is ahead of the curve as we explore imaginative ways to exploit the data these provide for the common good of all.

Field service and customer transparency

These days, a business is as good as it is transparent. Businesses are on unsteady ground because of the ever changing face of social media and a never-seen-before demand for information. With many sources of info on the internet, being credible is a sure way of building trust and loyalty among clients.

Here is an example. Customers will always believe what they see. If they see the work you put into furnishing their favourite products, you have a greater chance of getting their approval. They can invest more in what they see. The clothing merchandise Patagonia did this for their Footprint Chronicles line to show how their jackets are made and worked out fine for them.
Transparency is a must. Nowadays, customers never forget when they feel cheated. It is even harder to ensure transparency because many clients are also experts who scrutinise every detail. So, how can you keep transparency at the forefront?

Have transparent workforce management

Customers always look for new information and want to be in the know. There is nothing worse than not being able find a product manual or an easy way to set up appointments. By giving your clients a self-service option, they can pick the services they want. This leaves more time to get stuff done rather than answering unending service calls from dissatisfied customers.

For instance, you could have a field service customer self-service application that allows customers to look for personalised services, a machine manual, book appointments, or solve any other problem. Customers then get feedback anytime. This one-on-one approach can help customers feel like their questions are being answered. They?ll also not go through the hassle of long hold times to reach an available customer service representative.

Create transparency in field service repair projects

If field technicians have access to field service software, it allows technicians to be more open to customers. This gives them vital information like customer history and the ERP, so that they can explain changes that were made after past enquiries and what is being done in current products. Such information can be a guide for future updates or let the techs suggest products that suit a client’s taste. Unlike always staying offline and out of touch with your client, using field service software can allow entry of allowances and mileage, and also let the customer know the delivery time for their products.

Show customers what they’re paying for

With field service automation, billing will also be transparent. By using the available information about your field service solution, the station can send updated service reports to the customer like mileage, allowances, parts, hours worked, and photos of broken parts from the service. After the customer authenticates the transaction with a signature, the field service agent can generate and sent to the customer an invoice based on the agreed upon services. In case allowances and mileage can be forwarded to the customer, it will be shown on the invoice.
Because you use field service automation, it means that the customer will receive the invoice really fast ? in days rather than weeks ? and transparency will skyrocket because the whole experience of the service will leave a permanent mark in their mind.

Mistaking information for transparency

Being honest with your customer is the one thing. Wasting their time with unnecessary information is another. Here is an experience I had with a small retailer. Tracking information is only useful if it has recent updates and is accurate. If the company want to use real time tracking, let them do so under one condition ? updates should be regular and on time so as not to leave the customer frustrated because they also make plans based on the same information. Late updates shed light on the nature of the service command. Everyone hates cooked-up real time information.

A company must not always have a one to one exchange of information with customers to maintain transparency..

  • Use simple language that all customers can understand
  • Don’t use abbreviations that only employees know
  • Never ever air your failures and flaws to your customers

It is interesting that most of the tools we use to keep in touch with our clients and servicing their requests can also be used to gather data and iron out possible errors to improve products and services. This is a good chance for service providers to evaluate and make necessary amendments.

There are some areas that will need improving while others will not, nevertheless, the client needs to always be informed and know why things are the way they are. Not all details should be told, so filter what you share.

5 ways field service supports customer service

Sales organisations are always in motion, working to deliver the right product to their customers. To keep customers smiling all times is hard and only needs close communication and fulfilling promises that were made to them. This is where the field service delivery team comes in. Field service can either meet this demand or fall short plummeting satisfaction rates.
This is a task that relies on right people using various parts and information to get the job done. No matter what, the customer always expects to get exceptional services whether it be over the phone, chats, in the field, online messaging, over email, or social media.

These five field service points are suitable for any business model and guarantee excellent company-client relations.

Proactive service

A proactive service gives more to the customer. More attention is given to the customer so that the right actions, deliveries and repairs are done. By getting everything right the first time, the customer has less to do ensuring that they are satisfied with the services.
However, the field service technician is flooded with a myriad of unpredictable situations; overheating equipment, stalled machines, and insufficient precaution. But through field management software, they get more data about the customer and type of service or parts expected and they easily ride through any storm and prevent future damage.

Transparency

Nothing frustrates a customer more than a schedule that delays repairs. They easily ditch you for better services elsewhere. By offering the customer a service where they book appointments based on their own availability, we can easily sync this to the technicians and manager?s calendar. This not only saves time but also money from otherwise idle equipment.

On-site and off-site collaboration

Having seamless communication between field and office technicians is vital. Field technicians need to know more about parts, repairs, client maintenance history, and predict what should be changed in the long run. The faster they do this the better.

There should be a system that creates and automates communication between field and office technicians. Let each have the upper hand when providing parts, products or services to the customer.

Flexibility

Information is key to field service agents. They make the first impression since they make the initial contact with clients. Regardless of the resources, the field technician must always be armed with mobile tools they will need to access online resources and be ready for any emergency.

Actionable performance improvements

Customers demand excellent service a company could offer. But as the game constantly shifts, the service management technicians must also come up with plans to stay up to par with competition. All these stems from coming up with KPIs, measuring them and turning them into a workable plan for the future.
