What level of cooling performance can we expect from a Koolatron cooler? A Koolatron cooler can maintain its contents at a temperature approximately 40 to 45 Fahrenheit (22 to 25 Celcius) 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. The contents of the cooler can be maintained at approximately 38 deg. C Normal household refrigerators are usually maintained at 45 to 48 deg. At a temperature of 90 deg. The contents of the cooler can be maintained at approximately 48 deg.
Can a Koolatron cooler freeze and make ice cubes? The Koolatron cooler was designed to function as a cooler and does not have ice cube facilities. Operating in an air temperature below 65 degrees F.
The contents could become frozen slowly or frozen foods could be kept solid for some time. Most Koolatrons are not thermostatically controlled and run at maximum cold. Ask about the Koolatron Arcti-Kool Freezer? Model F86 (Specialty coolers with thermostatic controls are available for Medical, Scientific and other Premium applications). What temperatures can be expected from the Koolatron cooler in Heater mode?Temperatures in the range of 130 to 140 deg. F 54.4 to 60 deg. This is hot enough to bring hot food to a pot luck dinner or a picnic. 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 160 Degrees Fahrenheit (71 Degrees Celcius). At the upper temperatures these are used for Seniors? 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). How much power is consumed by your Koolatron coolers? Most of our current production coolers consume 4.5 amps at 12 volts.
The conversion is: 4.5 amps (X) times 12 volts (=) equals 54 watts. The P-9 consumes only 3 amps.
= (36 watts) On household current the power consumed by each cooler is less than 1 amp at 120 Volts. If my vehicles engine is turned off, how long can I safely leave the cooler plugged into my cigarette lighter socket before compromising the batterys ability to start the vehicle? The safe answer here is approximately 3 hours in most situations. Further limitations and factors are the relative condition of the battery and its 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 judgement is required when making the decision about whether or not to leave any device plugged in while away from the car.
Sometimes I dont know how long I will be away from the vehicle. How do I ensure that I have starting power when also running a cooler? To completely eliminate the burden of energy management, use a Battery Saver. It allows you to leave the cooler plugged in PERMANENTLY. The Battery Saver will automatically switch off the cooler when it senses that the vehicle's battery has dropped below 11 volts.
(That is about half discharge in most vehicles). This will leave plenty of power to start the engine. When the vehicle is started, the Battery Saver reconnects the cooler and active cooling begins automatically. 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 softdrinks and bottled water which can be consumed at temperatures above refrigeration range. How long does the cooler stay cool when unplugged? 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 110 Volt AC power to 12 volts DC and plug the cooler into mains power when not driving.
Is there any way to power the Koolatron cooler while away from a vehicle? Yes, we have a Koolatron Portable Power pak that has a power socket which can be used to power a cooler or other 12V accessories. This unit has about 17 amp hours of capacity so should run a cooler for 3 to 4 hours. It recharges at home or in your vehicle.
The Portable Power unit has booster cables attached so can be used to start your vehicle in case the vehicles battery has been drained. This unit also comes with a built in air compressor for emergency inflation of tires and other air filled devices. Can I put ice in my Koolatron cooler? Yes BUT not loose (any water inside the cooler will splash up under the cooling fins 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 end from the cooling fins.This way your contents get the benefit of two cold sources and you are not blocking the interior air circulation. Can I put the cooler in the trunk of my car?
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.How do I calculate the volume capacity of my cooler? 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 centimetres. One cubic centimetre is equivalent to 1 millilitre. Divide your cubic centimetres (millilitres) by 1000 and you now have the capacity in Litres. Multiply litres by 1.0567 and you will have the capacity in U. OR multiply litres by 0.881 to get Imperial Quarts.
Is there any time limitation on running the cooler on the AC adapter while in the house, office or dormitory? These units are designed to run 24/7.Make sure that there is good air circulation to the cooler vents and for the adapter. This will assure long life for both. Can we use a battery charger to operate a Koolatron cooler? When plugged into a vehicles cigarette lighter receptacle, a battery charger can be connected to the vehicles battery to keep it "topped up" while the Koolatron is running. Are there any concerns with long term full time operation? 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 surface. Every few months the external fins may accumulate dust 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 replug putting 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.
MAKE SURE TO REPLUG INTO COOLER MODE OTHERWISE YOU WILL COOK THE ENTIRE CONTENTS OF THE UNIT. Why does my cooler work on the AC adapter but not in the vehicle? 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.Why does my cooler work in the vehicle but not on the AC adapter? 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. Can we use an AC Adapter other than the one supplied by Koolatron? What should I check for if the cooler is not running at all? Are both ends of the power cord plugged in? Is there power coming from the socket or adapter being used. Check for kinks, knots or other damage to the power cord. Is it allowable to use a 12 volt extension cord to run the cooler further away than the 10 foot factory cord will reach?
There is a voltage drop in long cords so cooling performance will be degraded. Is a Koolatron cooler strong enough to sit on?
In most cases yes, but it's not a good practice as a heavy person could warp the lid thus affecting the seal and the cooling performance of the unit. What are some common complaints and how do we deal with these? 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.
Leave the lid open slightly (say by putting a pencil between the body and lid) (this may necessitate more frequent defrostings) Unplug the cooler for a period of time each day. Stand the cooler up into the fridge position. Cold air will leak out the bottom of the door and cooling performance will be less. The cooler is not cold enough. Place the cooler in chest position so the cold air stays inside.Make sure it has an ample power source. A weak power adapter or low voltage in the vehicle can cause decreased cooling performance. The fan must be running and all air vents internally and externally must have free access to air. Do not park the air vents up against curtains, walls or other obstructions. Make sure the fins inside and outside are free of ice and dust. The item "Koolatron 12 Volt Cooler 29 Quarts P27 Voyager" is in sale since Wednesday, May 18, 2011.
