When electrical current passes through the cube junctions, heat is transferred from one metal to the other. Solid-state thermoelectric modules are capable of transferring large quantities of heat when connected to a heat absorbing device on one side and a heat dissipating device on the other.
Here, a small fan helps to disperse the heat into the air. Conversely, you can also use the Voyager to keep food warm or even heat food up to 65 degrees C degrees F by simply flipping and reconnecting the power cord. Now here is the trick to making this device work a little more efficiently. It is unfair to expect that the device will chill your food and beverages quickly and effectively without a little initial assistance so I would suggest that you cool items down prior to putting them in the cooler.
I found that placing a frozen gel pack in the bottom worked like magic for me. Also, unlike a standard cooler, it is important not to pack it too tightly as you want to allow for space between the items to permit the passage of cool air or warm depending on your needs as the unit operates using a small fan mechanism. I found that it took between two and three hours for the unit to reach its optimal cooling temperature.
One of my neighbours is a long time Koolatron user and he spends a lot of time on the road in the summer time. He had never personally had a problem, but recommended that a couple of hours would be about the limit for such operation.
This solution would help ease your anxiety for those occasions when you may have to be away from the vehicle for more than a couple of hours. In conditions where you expect the cooler will be switched off for extended periods of time, do not store any foodstuffs in the cooler that will go bad under these conditions. Stick to soft drinks and bottled water which can be consumed at temperatures above refrigeration range. This is very dependent upon conditions.
Koolatron coolers are extremely well insulated and will provide many hours of cool protection, even when switched off. Try to keep the cooler in the shade. Instead of leaving the cooler in a vehicle overnight, use an AC adapter which converts standard Volt AC power to 12 volts DC, and plug the cooler into mains power when not driving. Yes BUT not loose, any water inside the cooler will splash up under the cooling fan and short circuit the electronics.
Put the ice in a sealed container, NOT a plastic bag. That way you can use the ice for drinks and it will help to rapidly cool the contents on really hot days. Keep the ice container at the opposite ends of the cooling fins. This way your contents get the benefit of two cold sources and you are not blocking the interior air circulation. NOT recommended. The coolers give off heat externally while cooling. If this heat is shed into a closed space like a trunk, it will eventually heat up that space.
These coolers need good ventilation to cool properly. Put the cooler in the chest position. At the halfway point in depth measure the inside length, width and height in centimeters.
Multiply these three dimensions by each other. This will yield so many cubic centimeters. Once cubic centimeter is equivalent to 1 millilitre. Divide your cubic centimeters milliliters by and you now have the capacity in Litres.
Multiply litres by 1. In North America call or e-mail to service koolatron. Make sure there is good air circulation to the cooler vents and for the adapter. This will assure long life for both. No, not directly. Do not place the adapter on carpeting since this tends to block the airflow up through the bottom of the case.
Instead, put it on a brick or tile or other smooth surfaces. Every few months the external fans may accumulate dust due to the point of blocking the airflow. Take off the end panel and vacuum and brush away any dust on these fins and fan. The internal fins may accumulate frost and ice occasionally during operation frequently during humid weather.
To defrost, simply reverse the current by unplugging the power cord from the small pigtail cord near the base of the cooler and re-plug using the red mark to the arrow putting the unit into heater mode.
The ice should melt off in 2 to 3 minutes. Remove any ice that falls off and wipe up any melt water. Some vehicles do not have power to their cigarette lighter sockets when the ignition is off. If the vehicle is running and the relevant fuse is good but the cooler still will not run then get the cigarette lighter socket tested. Make sure the AC adapter is plugged in. Check with a multi-meter to determine if there is at least a 12 Volt DC output voltage from the Adapter.
This is NOT recommended. There is a voltage drop in long cords so cooling performance will be degraded. The coolers are too cold and tend to freeze things inside: Move the cooler to a slightly warmer area of the home, office or dormitory room.
Koolatron also designs and builds a special Precision Temperature Controlled Cooler for those medical and other applications where the temperature must remain constant. They also make a good poor man's refrigerator because as long as you maintain a reasonably decent ambient, they act just like a real refrigerator, except they do not cool as fast.
They come in 3 flavors as follows:. The TC5 control is a non-adjustable heater unit. The control must be programmed at the factory to the customer requirement. It is strictly heating, there is no possibility of cooling. Temperature accuracy and precision is approximately 0. The PC3 control is a user adjustable cooling and heating unit. The user must program the unit within certain guidelines. It will automatically switch from heating to cooling as necessary to maintain the upper and lower set-point temperatures.
The PC3 control has a display, and requires a coin cell battery to operate; the battery needs replacement annually. The PC3 is the only user adjustable control we offer. None of the units have alarms. An alarm would have to have a sophisticated control so that the alarm does not get enabled until the set-point range is achieved after startup. The alarm range would have to be larger than the control range, thus requiring four set-points. Implementing the alarm would open a vast array of options, and this would be difficult to offer.
A Koolatron cooler can maintain its contents at a temperature approximately 40 to 45 Fahrenheit 22 to 25 Celsius degrees lower than the temperature of the surrounding air. It is best to load pre-cooled food or drinks into the cooler.
As a rule of thumb, it takes about one hour per pound of material loaded into the cooler to bring it from room temperature down to maximum cold. At a temperature of 80 deg. F 27 deg. F 3 deg. C Normal household refrigerators are usually maintained at 45 to 48 deg. At a temperature of 90 deg. F 32 deg. F 9 deg. So what level of cooling performance can you expect from a Koolatron cooler?
The average Cooler is capable of about 38 to 40 degrees lower. As a rule of thumb , it takes about one hour per pound of material loaded into the cooler to bring it from room temperature down to maximum cold.
At a Hot Ambient temperature of 90 degrees Fahrenheit, the Koolatron Cooler will keep your food at 45 to 50 degrees. Is your Truck that HOT? Not likely. At 80 degrees, the Koolatron will keep your food at a temperature of from 35 to 40 degrees Fahrenheit. Normal household refrigerators are usually maintained at 45 to 48 deg.
Most Koolatron Volt coolers are not thermostatically controlled and run at maximum cold. Most Koolatron Volt Coolers consume 4. The conversion is: 4. The P-9 consumes only 3 amps. On household current the power consumed by each cooler is less than 1 amp at Volts.
In most cases, a Koolatron Volt Cooler is all that you will ever need. Temperatures in the range of to deg. This is hot enough to bring hot food to a pot luck dinner or a picnic.
Practice safe food handling wisdom and do not keep food in the Koolatron on Heater mode for longer than about 45 minutes.
These temperatures are in the prime bacterial growth range so it is very dangerous to store foods at these temperatures for long periods of time. If you have a long way to go, bring the food refrigerated and cook it at the destination.
If you need dedicated Heater Boxes, Koolatron can provide these with no cooling capability ranging in temperature up to Degrees Fahrenheit 71 Degrees Celsius. At the upper temperatures these are used for "Seniors" meal delivery programs, or School meal programs. Mid range Heater Boxes are used as portable incubators for rare animals or for incubating medical swab cultures on the way to the lab.
Lower heat settings are used to keep utility workers mitts warm or for storing construction adhesives in winter so they can be dispensed in cold weather. Super precise temperature holding is available. Most of our current production coolers consume 4. If my vehicle's engine is turned off, how long can I safely leave the cooler plugged into my cigarette lighter socket before compromising the battery's ability to start the vehicle? The safe answer here is approximately 3 hours in most situations.
Actual conditions will vary depending upon the number of electrical devices that have been switched on during the last part of your drive wipers, lights, blower, defogger, radio, cell phone, aux heater, cooler and or other accessories and what driving conditions have just been experienced high speed highway or stop and go traffic.
Further limitations and factors are the relative condition of the battery and it's charging system as well as season, temperature, and weather conditions. Under ideal conditions a cooler could be run for many hours on just battery power. Under the worst combination of conditions, accessories could potentially deplete the battery in 10 to 20 minutes. Some vans have 10 or 12 bulbs lighted when the interior lights are on.
Just these lights can drain a battery below starting power in about 15 minutes, without any other electrical device being present. Good judgment is required when making the decision about whether or not to leave any device plugged in while away from the car. Sometimes I don't know how long I will be away from the vehicle, how do I ensure that I have starting power when also running a cooler?
