| I recently received my hygrometer and its reading 81 degrees and around 48 for the humidity. After I recharge my dessicant packs they still turn pink within a matter of days...... I thought they would stay blue for a while sinse the humidity isnt high or am I wrong? How long should dessicant packs last before a recharge? |
| I'll bet it strictly depends upon the dessicant. I use a few types in my safe, and the general household use "damp rid" does not last more than two weeks in the wet summers here in NOVA. But I also have t a large rechargeable/plug in piece that will generally last more than a month (probably because of the damp rid is acting faster). Please also consider using a VCI in addition to straight moisture control - I like Remington moistureguard or the Bull Frog cups, but there are many great VCI products out there now. |

Check for gaps between the safe and the door. Mine would do the same thing until i put a weatherstrip seal on the door. Now, the humidity stays low and i only need to recharge the dessicant 1-2 times a year. Everything seems to be fine its a brand new safe and I have a dehumidifier but its just keeps happening. .... |

When you say you have a dehumidifier, are you talking about a goldenrod type or an electric condensation unit? 48% RH is not that low and if you have a goldenrod type heater it will drive moisture out of the safe contents for a while. Yes I have a golden rod.... 48 is low enough where I shouldnt need to recharge the dessicants every couple of days though correct? |

Heaters reduce relative humidity, they do nothing to the absolute. 48% at 81 degrees F is still quite high and probably from inadequate seals on the door. Foam sealing tape that is self-adhesive could work to slow the leaks. Remember, if the power fails and temperature drops due to the heater, you could have condensation. |

If you add a heating rod, you don't want the door sealed as mentioned above. They drive the humidity out, and if it sealed, there is nowhere fir it to go. My Liberty has seals that swell and seal off during a fire. Thats what I have a liberty safe...... I guess I just have to recharge them every couple of days until I find a solution. |

I am in the same boat so to speak, National Security safe with a Golden rod and the Remington plug in desicant things. My safe has a hole in the top for the ventilation, but if I seal the door really well there is no air to flow through correct? As I am understanding this thread, if using a golden rod do not totally seal tight the door correct? My hydrogeometer is usually about 45%. I oil my guns about once a quarter maybe a bit longer for those that are not used, and have not had any rust, in over 20 years in wet western WA. But the safe has always been in a heated room also. |

They make solid state dehumidifiers. Ever Dry or something like that. Run on AC power and you need a drain for the condensate. But they also give off heat so they work in both ways. By solid state I mean electronic refrigeration. Thermoelectric cooling. Peltier cooling. |

I too have a National Security safe (it's a great safe!. The hole in the top is for the factory to grab the safe while it's being manufactured; that's what the factory rep told me when I bought my safe direct from them back in the '80's. While it's not for ventilation, it will still leak air (and moisture) just like any other hole or orifice in the safe. Mine? I don't worry about it, even though I live in north AL, I don't have a moisture/humidity problem. I have my safe installed in a room off the garage that is air conditioned and heated. Good luck! |
