Protect Your Equipment This Winter from Freezing Conditions
Protecting your rental equipment from inclement weather conditions is critical during the winter season. Nationwide Boiler recommends the following in order to ensure that your boiler equipment continues to operate while facing freezing conditions. Refer to the pictures below for several shelters our customers have used to ensure their equipment withstands the cold.
- Enclose both the front and rear of the boiler area and use an external heat source to minimize freezing conditions.
- Install heat tracing with insulation to protect exposed stagnant water lines.
- 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.
- 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.
- When an extended boiler down time is expected, completely drain the boiler and stagnant water lines.
The above are recommendations, however, use sound engineering judgment calls when there are concerns of possible freeze damage to the equipment. Call us if you have any further questions at 1-800-227-1966.
