What can the water temp be set to on a hot box or is it preset to a certain temp?
A water filled heater should be set to 95°-100° the critical point of nitrous starts around 96.8° above this temp the nitrous all turns to a gas and the pressure starts to rise very quickly. While it is a good idea to keep it at 95° since then the nitrous will never reach critical temp. However due to the laws of physics a tremendous amount of energy is required to cause phase so if it is kept below 100° and you accidently forget and leave the bottles in the heater longer than intended the amount of time to get the nitrous to go through phase change and reach 98° is approx much greater than that required for it to reach 90° to 95° or approx a thousand to a thousand and fifty psi. So its up to the user if its summer and you use a transfer pump to charge your bottles then 95 should get them to temp pretty quickly and heat loss in the car will not be a big concern, however if you use a trashcan full of ice water to chill the small bottles for filling and/or it is cold out and heat loss in the car is a concern then 100° will heat the bottles a lot quicker.

Some teams heat their saunas to 120° or more, to ensure that the bottle heat quickly, this is inherently a lot more dangerous as overpressurization can occur quicky also if you are not carefull you may heat the outside of the bottle without heating the nitrous inside evenly (heat soak) resulting in quick pressure drop during the run and low trap speed and lean tunes.



PS A hot box uses air to heat and since air is so much less dense than water or nitrous the temperature of the air must be kept high to allow the bottle to heat quickly at all, this type of heater is prone to only heating the outside of the bottle and requires constant monitoring unless you want to trust the shut off system, I never felt comfortable.
