The CoolBot
®
transforms any well-insulated room, shed, or trailer into an affordable walk-in cooler using a
standard air conditioner. When choosing an air conditioning unit for use with your CoolBot
®
temperature
controller, you will want to consider the following factors:
Intended Use
Temperature Needs
Cooler Size
Quality of Cooler Insulation
BUILDING A COOLER
There are many different options for creating a walk-in cooler for your CoolBot
®
, including building a shed-like
structure, sectioning off a part of a garage or barn, or repurposing a cargo trailer. The key to building an
efficient cooler is to create an air-tight space and invest in proper insulation. The industry standard insulation
for a walk-in cooler is at least 4 inches of rigid closed cell foam in the walls, ceiling, and floor for a minimum
insulation value of R-25. Please see our website for more information and videos on building an insulated walk-
in cooler for your CoolBot
®
.
SIZING THE AIR CONDITIONING UNIT TO YOUR COOLER
It is important to choose an air conditioning unit that is appropriately sized for the space you will be cooling.
Please see the chart below for general guidelines for sizing your AC unit to your cooler space in order to
maintain an ideal storage temperature of approximately 38°F/3°C for most vegetables and 4245°F/67°C for
flowers.
*Please note the recommendations in the chart assume that the cooler is relatively air-tight, has adequate
insulation, and that the door is opened no more than 6 times per hour. If these conditions are not met, you will
want to choose an A/C unit with higher BTUs (British Thermal Units) than those listed to compensate.

Additional Sizing Considerations:
You may need to install multiple A/C units and CoolBot
®
controllers for cooling an area larger than
those listed in the chart above.
If you will be entering and exiting your cooler frequently, you might consider installing vinyl strip doors in
addition to using a higher output AC unit.
Glass display doors, common among florists, are less efficient than an insulated door so you should
choose a higher output AC unit than is recommended for your cooler size.
For florists, choosing an oversized AC unit can be helpful because the fan speeds can be kept lower,
so as not to disturb delicate flowers.
If your desired temperature is 50°F/10°C or above, you can choose an air conditioner with a lower BTU
output than is recommended for your cooler size.
TYPES OF AIR CONDITIONING UNITS
There are several types of air conditioning units, all with varying degrees of compatibility with the CoolBot
®
controller. It is important to understand their strengths and limitations when choosing a type for use.
Window-Mounted Types
Window-mounted AC units are designed to be easily installed through an open
window and are preferred for use with the CoolBot
®
because they are durable,
efficient, and offer the widest selection of compatible brands. Several models offer
an Energy Star rating for meeting certain guidelines regarding energy efficiency,
thereby saving you money on electricity.
Mini-Split Types
Mini-split A/C units are generally more efficient and take up less space than window-
mounted types, however, they can cost more than twice as much. These units are
often more affordable and easier to find when shopping outside of the United States.
The CoolBot
®
is compatible with several mini-split brands but check with the
manufacturer that it will function in the lowest outside air temperature for your climate.
Portable AC Units
Portable AC units are far less efficient than window-mounted and mini-split types. ONLY
Whynter brand models are recommended for use with the CoolBot
®
, and it MUST be a Dual
Hose Model. These portable units are only effective for keeping your cooler at 50°F/10°C or
above. If colder temperatures are required, you will want to select another type of air
conditioner.
Roof-Mount/ RV Units
Roof-mounted and RV type units are not recommended to use with the CoolBot
®
.
AIR CONDITIONER REQUIREMENTS
You must choose an AC unit with Digital Display and Automatic Restart for the CoolBot
®
to function
properly.
Please see the chart on the following page for additional information about specific AC brands and
models that are compatible with the CoolBot
®
.

AIR CONDITIONER BRANDS
Not all air conditioner brands are compatible with the CoolBot
®
, so it is important to select one that has been
tested and approved for this use. The chart below is a guide to choosing an AC unit that is known for being
compatible with the CoolBot
®
controller. We can NOT guarantee compatibility of any brand or models not listed
in the chart below.
IMPORTANT NOTES:
All AC units MUST have a Digital Display and Automatic Restart for use with the CoolBot
®
.
LG is the top preferred brand due to their reliability and easy installation.
If using the CoolBot
®
in colder temperatures, we recommend selecting a unit from LG Electronics,
Danby, Haier, or GE. Check with the manufacturer for detailed information on the AC unit’s temperature
limitations.
The chart below lists some models as “Limited Experience - Limited Support. This means that users
have reported good results, however, we do not have enough data to classify them as Compatible.
