Kendrick - Computer Heater

Kendrick  Computer Heater

The Kendrick Laptop Computer Heater.	The laptop computer is placed on top of the heater.	Place laptop in a box as shown to create a small heated environment.

This heater is excellent for keeping your 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.

Kendrick recommends placing the heater inside a box placed on it's side and then placing the computer on top of the heater. This will create an enclosed environment that will create a pocket of air around your computer that is warmer than the ambient temperature.

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.

Using the System

Kendrick recommends 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, they recommend a controller setting that represents about 20 to 40% If you are using FireFly or MICRO FireLite Heaters, they recommend a setting of about 60 to 80%.

If moisture has already condensed on your optics, Kendrick recommends 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.

Power Source

With the exception of our #2021-A Pad Heater, the dew control systems require 12 volts DC. If you are using a battery to run the system, they 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.
