FAQs

-60°F Gray Alloy Vinyl (Extreme Product) -20°F Black D-15 Vinyl (Standard Product)

Ready To Ship models come standard at 120VAC, but we offer 208, 240 & 480VAC custom solutions.  Anything we make below 120VAC or over 240VAC, along with anything built to run over 24Amps, will be non-ETL.

This could cause overheating.  NEVER add extra insulation to any of our heating products.  It will void any warranty and MAY BE HAZARDOUS.

All Powerblanket® products are shipped FOB Salt Lake City, UT, 84119.

Thermal Load is the amount of energy required to keep a space or object at a desired temperature.  When the environment is cooler than the desired temperature of the space or object, the thermal load is a heating load and is the amount of energy required to be added to the space or object in order to achieve the desired temperature.  All things being equal, the heating load will increase when the ambient air temperature decreases, or when the wind speed increases, or if the space or object is placed in contact with a large thermal mass, like a cold concrete floor.

Rapid Ramp (RR) Drum/Bucket is 100°F (± 10°F) / 38°C (±5°C)
PRO Drum/Bucket is 145°F (± 5°F) / 63°C (±3°C)
Foam Box Heaters 110°F (±10°F) / 43°C (±5°C)
Tote Heaters 145°F (± 5°F) / 63°C (±3°C)
DEF Tote Heaters 70°F (± 10°F) / 21°C (±5°C)
Gas Cylinder Heaters (propane) 90°F (± 10°F) / 32°C (±5°C)
Multi-Duty (concrete curing) from approximately 100°F to as high as 150°F
Extra Hot (ground thawing) 150°F (± 10°F) / 65°C (±3°C)

A few things may cause this: ambient temperature, wind speeds, product location, and possible additional variables.
