Custom Hazardous Location Heaters

Working in hazardous locations means you have to exercise serious caution regarding procedure, protocol, and equipment usage. What’s more, heating in hazardous locations takes all the more care and detail to make certain you aren’t adding fuel to a potential fire. This is why Powerblanket offers products certified to national safety standards.

CID2Difference between Class I Division 1 and Class I Division 2

Many people who work in hazardous locations are familiar with these terms. For everyone else, here’s an explanation. The classifications referenced as CID1 and CID2 regard the operation of electronic equipment in hazardous locations. CID1 is the identifier used for locations where ignitable concentrations of flammable gases, mists or vapors could possibly exist under normal working conditions. This classification also covers locations where the same gases, mists or vapors may exist frequently due to repairs or maintenance in the area. It also includes potential scenarios where gases, mists or vapors could be leaked by faulty or damaged equipment.

CID2, on the other hand, represents all locations where concentrations of flammable gases and/or vapors and/or mists are present in the air under operating conditions outside of the norm. So CID1 covers areas where such hazards are normally present, and CID2 covers areas where such hazards aren’t normally present but certainly could be under abnormal circumstances. Most importantly, if a product is CID1 or CID2 certified, it means that product is safe to use in locations that are CID1 or CID2 rated hazardous locations.

We understand that hazardous location heating is nothing to take lightly. And we understand that heating products should be engineered to the highest standards of quality and safety. We’ve based our business on this simple reality and are able to customize our safe and innovative heating solutions to a myriad of industries because of it. Our custom heating solutions can be designed and certified to Class I Division 2 (CID2) safety standards. We are certified for all four gas Groups, A, B, C, and D and up to a T4 Temperature Classification.

Freeze Protection in CID1 and CID2 environments

Hazardous situations can present themselves even when the temperature is below zero. Flammable gases and material are not limited by how cold it is outside. It is very important that you know what options you have in keeping temperature sensitive material warm when some methods of doing so are restricted due to CID1 and CID2 location hazard ratings.

Insulation can help reduce the impact of cold weather on your equipment, but using a heater is more effective so long as the one you use does not compromise workplace safety.

Are heaters unsafe to use?

Some heating options are a really, really bad idea to operate in CID1 and CID2 environments. Any type of open flame heater, including propane heaters and torches, greatly increase the chance of ignition of flammable material, potentially leading to an explosion of catastrophic proportions. Unit heaters or location heaters are also a poor choice due to the lack of directional control over heat output.

Heat trace can sometimes be used, depending on what type of hazards are in the work area, but electrical wiring within the tape could be accidentally cut and exposed, igniting vapors and resulting in destruction.

The best choice for C1D2 hazardous location freeze protection is heated blankets, ideally ones manufactured by Powerblanket.

Need Custom Heating for Your Equipment? Answer These Questions

Do you need custom heating for a specific and unique application? Although there are various standardized heating solutions available, to determine the right solution, either standard or custom, a few initial questions need to be understood. The first of the discovery questions is to identify the desired result of the application which is generally one or a combination of the following:Custom Heating

  1. Freeze Protection:  Generally to protect from the elements or cold climate
  2. Temperature Maintenance:  Maintain a specific, constant and optimal temperature
  3. Added heat or Increase Temperature:  Add heat  and Increase temperature higher from starting point

For example, a pipe heating application may require higher energy/wattage to thaw a frozen pipe and then settle to a moderate power/wattage for continual freeze protection and flow control long term.

An epoxy/composite curing application may require pre-heating at higher temperatures prior to the epoxy being applied and then maintained at a higher temperature for optimal curing.

Begin with These Steps

  • Gather as much information as possible using the Custom Application Questionnaire. Be thorough.
  • The dimension needs to be as built, not a CAD drawing .  ALL dimensions must be submitted to the custom team for quote.
  • Once quote is accepted and PO is sent, engineering will begin.
  • Custom products will normally be completed within two weeks.

Custom Application Questionnaire

Once we understand the problem, these types of questions reveal the best solution:

  1. Which of these best describes the system requiring Cooling: drum/bucket, tote, tank, gas cylinder, pipe, flat surface (vertical or horizontal?), other?  
  2. Can you provide drawings and/or photos?  
  3. What are the critical dimensions of the system?  
  4. What material is the container or surface made of (i.e. tank wall, drum wall)? How thick? 
  5. What is the substance being Cooled (i.e. water, oil, pipe contents, concrete, frozen ground)? 
  6. Is this a flowing system? If so, what is the flow rate (include units, gpm, cfm, etc.)? 
  7. What is the expected ambient temperature (include units, °F, °C)? 
  8. What is the maximum expected wind velocity (include units, mpg, km/h, etc.)? 
  9. Are there other environmental conditions that may be relevant? 
  10. What is the beginning temperature of the substance or contents (include units, °F, °C)? 
  11. What is the desired final temperature of the substance or contents (include units, °F, °C)? 
  12. What temperature range is acceptable? 
  13. Are there upper or lower temperatures where the substance or contents will be damaged? 
  14. Is there a time frame requirement for the initial cool down? 
  15. What power source is preferred (120, 208, 240, DC)?  
  16. How far away is the power source (cord length)? 
  17. Do you require UL/CSA certified products? 
  18. Is your location considered hazardous (Class I Division 2)?
  19. How many units do you need now and in the future? 
  20. What is the required delivery date? 

Custom Heating Case Study

Powerblanket completed a project for a large chemical company to solve freeze protection problems. The company stores a chemical solution in large 4,000 to 8,000 gallon stainless steel tanks. Their customers live in various climates throughout North America. This solution is water based and freezes at roughly 32°F.  This company needed freeze protection and to maintain regular temperatures between 40°F -70°F.

The question became, “How do we provide a ‘one size fit all’ customized solution for various climates?” Powerblanket created a modular custom design, adjustable by region and tank size, that came in two pieces.

Powerblanket engineers calculated the amount of heat and insulation required to combat freezing temperatures and wind chill to maintain optimal temperatures in these various climates. What appeared to be a complicated application turned into a simple and effective custom solution.

So many industries need heating solutions, and not just during the cold months either. Epoxy curing, chemical storage, viscosity maintenance, food preparations, concrete curing, and much more all benefit from innovative temperature regulation year round.
