With some chemicals, it’s critical to keep them cool because they will lose their concentration when they heat up. Sodium Hypochlorite is a prime example of that. As it heats up, it starts to lose its strength, and it begins to release gas and free radicals. Its strength can diminish dramatically with heat and UV.
So it’s important to keep the chemical as cool as possible from the moment it arrives at your facility. Other chemicals are similar—if they become too warm, they won’t perform as well as you need them to.
