Freezing conditions pose a huge risk to boiler equipment if it is not properly protected from the harsh elements. In order to ensure that your unit continues to operate while facing freezing conditions, Nationwide Boiler recommends the following:

1. Enclose both the front and rear of the boiler area and use an external heat source to minimize freezing conditions.
2. Install heat tracing with insulation to protect exposed stagnant water lines.
3. Utilize an appropriate heat tracing method (electric or steam tracing) to all of your main lines and piping components. This includes the following lines which should be heat traced regardless if the boiler is in operation or not (in freezing conditions): sensing lines (steam drum to CMR, high steam and steam gauge), auxiliary low-water-cut-off, water column and level control blowdown. Depending on the length of piping runs, the main and continuous blowdown should also be heat traced.
4. In addition to heat tracing on stagnant sensing lines, drain the lines and fill them with a 50/50 (water/glycol) solution, making sure to re-connect the line.
5. When an extended boiler down time is expected, completely drain the boiler and stagnant water lines

NOTE:

• The above lines are considered stagnant lines and should be heat traced regardless if the boiler is in operation or not (freezing conditions).
• Nationwide has also done the following in addition to heat tracing on the stagnant sensing lines: Drain line, fill with 50/50 (water/glycol) solution, re-connect line.
• Depending on the length of piping runs, the main and continuous blowdown should also be heat traced.
• For extended boiler down time, drain boiler and stagnant water lines completely.

The above are recommendations; however, use sound engineering judgment calls when there are concerns of possible freeze damage to the equipment. Contact Nationwide Boiler if you have any further questions: 1-800-227-1967

At Nationwide Boiler we continuously upgrade our stock of rental equipment, allowing us to offer our customers a variety of options to fit each individual need. We are currently assembling two (2) 650 HP, 250 psig design, low NOx mobile boiler rooms. Below are some pictures of one of the boilers being put into its trailer, take a look!

Three new ultra low NOx (ULN) mobile boiler rooms have been added to Nationwide Boiler Inc’s growing fleet of rental boiler systems.  The boilers have been specifically designed, manufactured and assembled to meet the increasing demand of steam for commercial and industrial boiler users located in California and other parts of the nation who must comply with strict air emission requirements. All three units have been pre-certified to comply with permitting agencies including the South Coast Air Quality Management District (SCAQMD) and the Bay Area Air Quality Management District (BAAQMD).

The three new units include a pair of 47.5 hp (200 psig) ULN boilers enclosed in 27’ single axle vans and one 650 hp (250 psig) ULN boiler enclosed in a 53’ van.  All boilers include 9 ppm gas-fired burners (with the option to fire propane fuel), deaerators, feedwater pumps, chemical treatment systems, blowdown separators and sample cooler stations.
