Kendrick Laptop Heaters
As electronics and their operating environment approach the freezing mark (0°C/32°F) it can affect the proper operation of the electronics. LCD displays stop functioning, data writing to data cards can drop out, mother boards can seriously slow down or stop functioning altogether. In some cases LCD computer screens will crack when brought into a warm environment from a sub zero environment. Battery life can be seriously compromised in freezing temperatures. Moisture in the form of dew or frost can condense on sensitive electronics in humid environments, destroying the circuit boards.
The solution to any of these problems is to use one of our heater controllers and one of our heat wraps/tapes of the proper size for your application and this problem will be over with.
Depending on your situation, we have heaters for hand controls, laptop computers, data recording meters and many other devices that require a specific temperature or a warm internal environment to operate effectively and safely. And if we do not have it, we can make it.
Please note that our Laptop Computer Heaters require the purchase of one of our Dew Controllers in order to be functional. The heaters are not a stand-alone product. Also, our systems are all 12 VDC with the exception of our #2021-A Digi_Klear Pad Heater, which runs on 120 VAC.
This heater is excellent for keeping your ipad, tablet or laptop computer free of moisture and functioning properly in wet, humid or cold environments where dew, frost or cold may cause serious damage to your computer or slow its performance due to cold temperatures.
When used with Laptop computers, this heater performs best when the computer is within a confined environment such as a small computer tent or even a cardbox box placed on it's side. Place the heater inside the tent or box and then place the computer on top of the heater. This will help create an enclosed environment that will create a pocket of air around your computer that is warmer than the ambient temperature. Tablets or iPads can simply be placed on top of the heater.
These heaters also make excellent eyepiece heating pads. When not in use, simply put your eyepieces on the heater, optic side down and it will keep your eyepieces dew free.
We recommend that you put your heaters in place at the beginning of an observing session and turn your controller on right away. If you are using Premier Heaters, or heaters for Newtonian or RC Telescopes, we recommend a controller setting that represents about 20 to 40% If you are using FireFly or MICRO FireLite Heaters, we recommend a setting of about 60 to 80%.
If moisture has already condensed on your optics, we recommend covering the optics, turning the heaters on high and waiting 20 to 30 minutes. Once the moisture has cleared, lower your controller setting and resume observing.
Our dew control systems require 12 volts DC. If you are using a battery to run the system, we recommend a 5 amp hour battery as a minimum. If you want to run the system from a wall plug, you will need a step down converter with a minimum output of 5 amps.
Pictured to the right are our Regulated 120 volt to 12 volt DC power supplies which are excellent for operating our systems from a wall socket. We also build portable 12 volt power packs and offer other power solutions that can be used with all your astro equipment that is used in the field. See Power Packs for more information on the power systems we offer.
