Please note that when considering the purchase of the Kendrick Dew Remover System, you will need to purchase one of our controllers along with the heaters. The heaters do not operate without one.
The Kendrick Dew Remover System has been the industry standard for effective dew removal and prevention on all optical surfaces where moisture condensation is a problem. Kendrick is the original innovator of these systems and we continue to lead the marketplace with our innovative product design and concepts. Our system has heaters for almost all the optical components used in amateur astronomy, several controllers with different levels of functionality and is the most sophisticated on the market.
Repeated field testing on many types of optical surfaces under many conditions and our thousands of satisfied customers has proven the effectiveness of our product over and over. Amongst other things, our system has these attractive features:
- It is energy efficient. Our controllers use almost zero power except for that required to illuminate the LEDs (which is VERY little!). Rather than use energy, our controllers actually conserve battery power by having programmable settings to control the heaters for precise application of heat. The systems are programmable with variable duty cycle, temperature variance, dewpoint variance or set temperature, depending on which controller you use.
- It is lightweight.
- It is high quality. We use only the best quality components in our system. We do not compromise on the integrity or performance capabilities of our product.
- It will keep every optical surface you are using free of moisture in many different circumstances.

THE #2002 PREMIER DIGITAL CONTROLLER
OUR TOP OF THE LINE CONTROLLER!
We are pleased to announce the introduction of our new digital PREMIER POWER CONTROLLER. It is the most advanced controller of its type available with many new features not seen before. For you astro imagers out there, the Premier controller is completely RFI (radio frequency clean) free.
Since the introduction of the Kendrick Dew Remover System in 1994, we have had many requests for a more advanced controller. These customers have wanted more control over the heaters on their telescopes. We have taken it one step further and have provided a platform that will offer centralized power management of telescope accessories and dew prevention heaters.
Now, various devices, accessories and heaters can be powered and controlled from one central device. Now, not only heaters, but accessories such as Dobsonian cooling fans, digital setting circles, illuminated eyepieces, Telescope motor drives, Astro Systems Dewguard secondary mirror heaters, motorized focusers etcetera can be powered from the controller (Some plug modification may be required).
When used for dew prevention, the PREMIER POWER CONTROLLER is programmable over a number of different parameters explained under PROGRAMMABLE FUNCTIONS.
The controller's many new features are:
- Built in low voltage cut-off (Outputs 1 through 5 only).
- RFI (radio frequency interference) free. Absolutely necessary if you are into digital imaging!
- LED display.
- LED brightness control.
- Temperature/Humidity sensing and control on two outputs.
- Your choice of Fahrenheit or Celsius operation.
- 6 outputs (2 of which are constant on).
- LED power on indicators for outputs 1 through 5.
- Outputs 1 through 4 are individually programmable.
- Numerical Keypad entry of operating parameters for utmost control of your settings.
- Remote control, programming and monitoring capability (optional software purchase required).
- Sensor readouts to show ambient air temperature, optic temperature, dewpoint temperature, humidity in %, battery voltage.
- The ability to enable or disable outputs (output #6 cannot be disabled).
- The ability to save up to 4 different configurations.
- A beautiful brushed stainless steel case.
- An optional brushed stainless steel cradle that connects to your tripod or Dobsonian telescope.
- Temperature sensors are calibrated. Combined errrors from uncalibrated ambient and optic temperature sensors can be significant.
The 2002 Premier Power Controller Package includes:
- The controller itself
- One temperature/humidity sensor for sensing ambient air temperature/humidity.
- One temperature cable for sensing optic air temperature. Additional cables may be purchased.
- A lanyard for hanging the controller.
- An instruction manual.
PROGRAMMABLE FUNCTIONS
Depending on the package purchased, the Premier Controller is programmable in the following parameters:
- Duty Cycle. Outputs 1 through 4 can be individually programmed to operate anywhere from 10% to 100% on.
- Temperature variance. Outputs 1 and 2 can be individually programmed to operate within a user specified temperature variance (ie: 5º above air temperature).
- Dewpoint variance. Outputs 1 and 2 can be individually programmed to operate within a user specified temperature variance (ie: 5º above dewpoint).
- Set temperature. Outputs 1 and 2 can be individually programmed to operate at a user specified set temperature. This function is useful if you have a device that needs to kept at a specific temperature for optimal performance.
- Outputs 1 and 2 can be programmed to mirror one another. For example, if output #1 has been programmed to operate at 7º above dewpoint, then output #2 would come on and turn off at the same time as #1.
- Enable/Disable. Outputs 1 through 5 can be set to on or off at any time. This is useful if, for example, you are running fans to aid in cooling your optics and you want them shut off.
- LED brightness. The LED Display can be set anywhere from a low setting for nightime use to bright for daytime use.
REMOTE CONTROL
We have developed software that will allow the controller to be programmed and monitored remotely from a PC. You have all the usual programming functions available to you and the software has an intuitive user interface that makes it easy to program and monitor the controller. The software will create a log file that can be imported into a spreadsheet program. This is useful should you have any reason or need to determine the operational functionality of the controller or heaters.
Downloadable upgrades for the software will be available on-line.
The software is an option and is not provided with the controller. We provide the necessary cable to connect the controller to your computer. You can extend the reach of the cable using a standard telephone extension cable.

THE #2001 Model VI STANDARD CONTROLLER
Our original. The one that started it all and still going strong!
The 2001 Model VI is a simple, easy to use, compact, lightweight controller. The power cord is 6' long and has a fused cigarette lighter plug. There are four RCA jacks on this controller to plug your heaters into. With the addition of an RCA splitter cord, 5 to 6* heaters can be attached. This would allow the operator, for example, to use heaters for the main objective, both ends of a finder or guide scope and a Telrad.
The power output from the 2001 Model VI controller can be varied from 40% to 100%. As the standard controller is a duty cycle switch, it controls the power getting to your heaters by shutting it on and off many times each minute. When the standard controller is set on low, the heaters will continue to draw the same amount of current, only 40% of the time. Low to medium is the recommended setting for most observing conditions.
Owners of 14" and 12" SCTs need to be aware that you will need one 2001 controller for the main objective heater and another controller for any other heaters you wish to operate. The heaters for these size scopes max out the capability of the 2001 controller.
Features & Specifications:
- Rugged Aluminum Construction (powder coated black).
- Adjustable 40% to 100% duty cycle heater control.
- Fused and reverse polarity protected.
- RFI (radio frequency interference) filtered around 1 Mhz. Your camera may experience RFI if it operates outside of the 1Mhz range. Check your cameras manual or contact the manufacturer to determine the operating range.
- Pulse Width Modulation duty cycle control.
- 4 outputs.
- 7 amp capacity, (will require upgrade from 5 amp to 7 amp fuse).
- LED Power on indicator.
- Supplied Velcro for easy attachment to your scope.
- 12 VDC operation (sorry, no 120 volt operation).
- Dimensions: 3.5" x 2.25" x 1.25" (1.75" with knob).

NEW! THE FIRELITE CONTROLLER
Our newest controller!
The FireLite Controller is the newest addition to our controller line and represents a new family of controllers and heaters for Kendrick. Designed for Astronomers and Astrophotographers who want the ultimate in lightweight, compact, Grab'n'Go gear. Ideal for use with small telescopes and DSLR Cameras.
Why does it represent a "new family of controllers and heaters"? Due to the very compact design of this controller, we have had to go a totally new connector for the heaters. For this reason we have created a new heater line to go with this controller, the FireLite Heaters.
Due to its size, the FireLite does have some limitations. Those limitations are:
It has a maximum load capacity of 1.5 amps.
Room for two heaters only.
It can only be used with our FireLite (NOT Premier or FireFly) heaters. The FireLite heaters have a special connector that will allow them to connect to the FireLite controller.
Features & Specifications:
- Extremely compact. 57mm L x 34mm W x 11mm H
- Weight (including power cord and plug)...60 grams.
- Incremental 20% duty cycle heater control.
- Fused and reverse polarity protected.
- 2 outputs.
- 1.5 amp capacity.
- LED Power on indicator.
- Low voltage cut-off control.
- 12 VDC operation.
- One button control. Very Simple!
- Dimensions: 3.5" x 2.25" x 1.25" (1.75" with knob).

We now offer heaters for the eyepieces used in bino-viewers. Instead of having two cables going to your controller, you can now have only one! These heaters are available in two sizes. For eyepieces with a barrel diameter up to 1.5" (40mm) we recommend the 2005-B1 binoviewer heater. For eyepieces wider than 1.5" (40mm) we recommend the 2005-B2 binoviewer heater.
The heaters have been built to use only as much power as necessary and thereby not waste energy. They have sponge insulation on one side to prevent heat being lost into the atmosphere. The heat is directed into the optics instead and because of this, less energy is needed to keep your optics moisture free.
The heaters wrap around your objectives, label side out and are held in place by elastic/Velcro attachments. Telrad heaters are held in place with an elastic band. The heaters for secondary mirrors are placed on the backside of the secondary and can be held in place by using the polyester batting found inside the secondary mirror holder. The .965/1.25", 1.25/2" and 2" are considered eyepiece heaters. The 1.25/2" and 2" are also heaters for camera lenses and certain binoculars.

| FIREFLY HEATERS |
|
Kendrick's new FireFly heaters are designed for the astronomer who requires a dew prevention system that is both economical in price and power. Although unable to perform up to the high standards as our original Premier brand of heaters, astronomers and anyone else requiring heated optics for dew prevention can depend on our FireFly heaters to perform under all but the most demanding observing conditions. Note that if your observing site gets temperatures that approach freezing on the nights you like to observe, you should consider the Premier line of heaters.
Having lower power requirements than our Premier heater line, these heaters will extend the life of your battery between charges. Using a different heater technology but operating under the same principle as our Premier line of heaters, these heaters will mildly disperse heat into your optics without compromising the figure of your telescope or camera optics.
As well, because of our unique manufacturing process, the FireFly heaters will direct their heat into your optics instead of losing it into the atmosphere. We have had these heaters independently tested for heat transmission and the resulting images below clearly show the effectiveness of our build technology. These heaters are very effective in directing most of the heat into the optics which is important if dew is to be prevented.
AN IMPORTANT NOTE: Some competing manufacturers of low wattage heaters make claims that their heaters, with half the wattage of our Premier line of heaters, will perform just as well as our Premier heaters, and at a much lower price! Well, this is true to a point but once you get down to temperatures approaching freezing, forget it, it just ain't gonna happen! You cannot escape the laws of Physics. Half the wattage means half the power, end of story. We make no such claims about our FireFly heaters. They do have their limitations.
The above image shows the outward facing surface of a Firefly heater.

The above image shows the inside, or optic heating side of a FireFly heater. This surface shows a +20º C difference from the outward facing surface proving the effectiveness of our manufacturing process in directing the heat into your optics.

We use high quality Velcro, elastic and connectors with these heaters. All the FireFly heaters come branded with our permanent, white identification label for easy identification in the field.

AVAILABLE JUNE
Kendrick's new FireLite heaters are designed for use with our new FireLite Controller. They have the special connector that allows them to connect to the FireLite controller (shown in the image to the right). It is important to note that any anti-dew heater with a RCA connector (this includes our Premier and FireFly heaters) will not connect with this controller.
IMPORTANT! The maximum amperage capacity of this controller is 1.5 amps. What does this mean? Basically it means that you will have to choose your heaters carefully, otherwise you will end up blowing fuses. All the heaters offered in the FireLite line are 1.5 amps or less. If you want to use two heaters with the FireLite controller, you will have to make sure that the total amperage of the two heaters does not exceed 1.5 amps. The amperage of the heaters is shown in the chart below.
Like all our other heaters, the FireFly heaters will direct their heat into your optics instead of losing it into the atmosphere. We use the same construction methods and materials as our Premier and FireFly heaters. These heaters are very effective in directing most of the heat into the optics which is important if dew is to be prevented.
So where do these heaters and the FireLite controller excel? See the partial list below:
- Anyone who wants to travel light with a small telescope.
- Anyone who uses a DSLR camera for astrophotography.
- Anyone who wants an inexpensive dew control system.
- Anyone who wants a compact lightweight solution for smallish optics where weight and balance are of importance (ie: Dobsonain secondary mirrors, finders, etc).

| HOW TO USE THE SYSTEM |
|
Put your heaters in place at the beginning of an observing session with the standard controller at or near its lowest setting. This should be good enough for most observing sessions. The high setting is only recommended for removing moisture already collected on your objectives or for cold winter nights. If moisture has formed on your optics, put the standard controller on high and wait 15 to 30 minutes for the optics to warm up. SCTs should clear by then, refractors can have excess moisture removed with a tissue. You can then reset the standard controller to a lower setting.
| POWER REQUIREMENTS |
|
We recommend, as a minimum, that a 12 amp hour rechargeable battery be used with this system. For individuals wanting to use household current, we have a 120v converter that put out 12v DC at 4.5 amps. We also have a converter that is rated at 10 amps output for. This is recommended for anyone with large power requirements.
For information on our 12v 18 amp hour deep cycle battery see the Kendrick Power Pack.
If you are planning to use your own battery, it is recommended that a deep cycle battery be used. If you are using household current it must be transformed to 12vDC and your transformer must be rated for the amp requirements of your system : if your system draws 1.5 amps, then your transformer must be rated for at least 1.5 amps.
| AMP HOUR RATINGS |
|
Please bear in mind that the following table of amp hour ratings is to be considered accurate only if the standard controller is set at high. Under normal operating conditions these ratings can be reduced by 40% to 60% as the normal standard controller setting is medium to low.
NOTE: Please keep in mind that the standard controller is fused at 5 Amps
and you cannot put a higher load on it without blowing the fuse. Looking at
the Amp Hour Ratings table, one can see that certain combinations of heaters
will go over 5 Amps. In that case more than one controller will be required
since the total load on a single controller should not exceed 5 Amps.
