Tomato Season Has Arrived!

The food processing industry relies heavily on companies like Nationwide Boiler for providing temporary steam for seasonal production, especially every summer when tomato season rolls around. One report indicates that California accounts for more than 90 percent of the U.S. production of tomatoes and in 2008 the state recorded a $953 million crop. As a food staple, tomatoes can be found in one form of another in most every household and are used in ketchup, pizza and pasta sauce and salsa, and many other products requiring tomato paste.

Nationwide has always taken a proactive approach towards renting equipment to tomato processors located in California's Central Valley. To keep the industry running, it is vital that Nationwide stock an adequate amount of trailer-mounted boilers in anticipation of an abundant harvest, on top of equipment already rented out to customers in other industries. It is also important that Nationwide continually stay in contact with tomato processors well in advance of the start of the season to ensure equipment is available and operating prior to tomato delivery.

One prominent processor located near Modesto, CA recently rented a 70,000 lb/hr trailer-mounted boiler with a CataStak™ SCR system and an EconoStak economizer. As in previous years, the equipment was delivered as the company was preparing to ramp up production prior to the first tomato-laden trucks rolling in. The addition of the CataStak and EconoStak improved boiler efficiency and the boiler easily met the 5 ppm NOx emission requirement required by the local air district. Not only is Nationwide providing an immediate supply of steam, but the company is also providing an environmentally “green” solution.

The next time you enjoy ketchup with your fries or when you add an extra scoop of sauce to go with your spaghetti, remember that Nationwide Boiler was involved in making sure those tomatoes made it to your plate, and we expect to continue to do the same - time and time again.

The "No Surprise" Check Off Sheet

We know that renting boilers, whether in an emergency, for scheduled maintenance, or to meet peak-season demands, can be full of surprises. Frequently, even experienced renters are surprised by what isn't included with most rental boilers. And most surprises are expensive - both in time and money.

Before you make a rental commitment call Nationwide Boiler, the "No Surprise" boiler professionals and ask if the above items are included, then call our competitors. We will do whatever it takes to make sure your rental project is a success, without any unpleasant surprise!

1.    Boiler Inspection
Have you inspected the boiler for plugged tubes, age, electrical etc? Some people rent boilers like calling a used car lot, negotiate price and then make a deal over the phone. This can be disastrous.

2.   Freight
Are the freight charges firm? Some boilers may have to take indirect route (road clearance problems) costing many thousand of dollars extra.

3.    In-transit Rental
When does the rent start and stop? On rail shipment, delays are common and your rent can keep running for three or four weeks in each direction adding one-two month's of unexpected rent.

4.    Steam Header Valve
Is one included with the boiler? New ones cost between $2,000.00 and $8,000.00 each.

5.   Blowdown Valves
Are they included? New ones cost $200.00 to $1,000.00 each. Are they mounted or shipped loose?

6.   Voltage
Is the boiler set up for proper voltage prior to shipment? Is the fan starter included? These items can save you money on fieldwork.

7.   Smokestack
Is one included and does it have properly sized transition pieces? Does it have to be shipped on separate truck? Freestanding stacks can be a real problem installing and removing. This can mean considerable fieldwork and expense.

8.   Control Panel
Is the panel mounted on the boiler or shipped loose? Is it weatherproof? Considerable time and expense in field wiring and tubing is common with remote panels.

9.   Guarantee
What will the boiler company cover on parts and callbacks? Some companies say return the broken part to the factory and you pay freight and installation labor.

10.   Economizer
Is one included and is it pre-piped? Do you need separate support and transition pieces? Will it be costly to install and remove?

11.    Blower
Is the blower on the boiler or shipped loose on a separate truck? This could be expensive for freight and installation costs.

12.   Weather Proof
Is the boiler designed for outdoor use? If not, additional cost will be involved to build an enclosure. Electrical controls could be water soaked during installation and shipping.

13.   Hydrostatic Test
Will you be charged for a hydrostatic test when the boiler is returned?

14.   Shipping Damage
Will you have to go back to the carrier to cover broken parts, etc. during shipment or will the rental company assume responsibility?

15.   Loading & Shoring of Refractory
Will you be charged for loading at the storage location including blocking of the firebrick? This can cost $2,000.00 to $5,000.00 and the same when you load out at job-site. This could mean $4,000.00 to $10,000.00 of unexpected cost.

16.   Safety Valves
Are the boiler safety valves set at the proper pressure to protect your steam system? If not, you may need new valves costing $200.00 to over $1,500.000 each or have them reset for $200.00 to over $600.00 each.

17.   Oil Pump
Is a pump set needed and is it included in the rental price? Is it pre-piped and wired as an integral part of the boiler unit? If not included, this could cost $500.00 to $5,000.00 material and labor over the rental cost.

18.    Testing
Has the proposed rental boiler been test fired recently? Is it coming direct from another job without shop check out? If this is the case many start-up problems can develop causing delays.

19.   Maintenance
Will you be charged for routine maintenance when boiler is returned to storage? Some charge for new gaskets, gauge glasses, painting, cleaning, washout, and flat tires on trailer and refractory repairs.

20.   Catwalks & Ladders
Is the boiler supplied with catwalks & ladders? These items can save you valuable time and money during installation and operation. Savings of $500.00 to $2,000.00 in man-hours are not uncommon.
