Protecting Critical Materials from Heat with Powerblanket ICE

Protecting Critical Materials from Heat

Under certain conditions and with certain materials, heat is the enemy: ruining epoxies, and interfering with the brewing process.  You can, however, protect critical materials from heat when the effects of heat are understood and proper precautions are in place.

Epoxy

Epoxy are many types of resins with similar properties and chemical structures. Typically used for adhesives, protective coatings and molds, epoxies are hard and notably inert after curing. Before curing epoxy is more fluid. The chemical reaction that results in epoxy is exothermic, meaning the reaction when epoxy is mixed creates heat. Adding more heat to this reaction makes the reaction advance faster. More heat, whether ambient temperatures or heat accelerators, will speed the chemical reaction.

In general, temperatures below 50°F/10°C are too cold for epoxy to cure properly. Temperatures around 70°F/21°C are ideal. If epoxy is kept in a container or spread in a thick layer, the heat from the reaction dissipates slower, and the heat of the chemical reaction can speed its own curing process (Legget).

Heat speeds everything about the curing process of epoxy.  If there is a need to store the epoxy, some plans for cooling must be in place.

Fermentation

protecting materials from heatHeat is an important part of the fermentation process; however, if heat enters the process at the wrong time, or lasts for too long, it can result in undesired flavors and aromas that compromise the quality of the spirit.  Spirits spend years locked inside barrels during the aging process, undergoing a series of seasonal climatic changes that trigger chemical changes. Controlling the temperature of actively fermenting wort (the sweet infusion of ground malt
or other grain before fermentation, used to produce beer and distilled malt liquors)
can have a major impact on the flavor of the finished beer. Fermenting above the normal temperature range may produce excessive fruity-flavored esters or harsh-flavored fusel alcohols (Stika).

Normal ale fermentation temperatures range from 68-72 °F/20-22 °C and lager fermentation temperatures from 45-55 °F/7-13 °C. The heat generated by an active fermentation can warm a typical 5-gallon batch of beer by 10 to 15°F/5.5 to 8.3°C (Stika).

Protecting Critical Materials from Heat with Powerblanket ICE

The key to protecting critical materials from heat is to prevent external heat from reaching your product.  An effective cooling solution should be able to remove as much heat as the environment is sending into the material you are trying to protect against the heat.  

FEATURES:

  • Blankets use Powerblanket’s patented heat-spreading technology in reverse to draw heat to the blanket and cool the contents of the container
  • Blanket cover and insulation are the same as the robust system used in the Powerblanket heating products
  • White vinyl reflects heat rather than absorbing the sun’s rays
  • Powerblanket Ice industrial cooling systems are portable (120VAC required)
  • Control the temperature of your equipment or bulk materials
  • Blankets can be left installed and running while bulk material containers are in use
  • Ready-to-ship industrial cooling/process cooling products are available for 15, 30, & 55-gallon drums, and for 5-gallon buckets.
  • Custom systems can be designed for a large variety of industrial cooling applications, and shipped within 2 weeks.
