Inside vs. Outside Installation
Outside installation is generally preferred whenever practical.
The BKool-24 moves approximately 559 CFM of cooled evaporator air through the dual 4-inch directional ducts. During operation, the condenser section produces heat that must be removed from the area being cooled.
When the unit is installed inside and the hot condenser air is exhausted outdoors, the building can be placed under negative air pressure. Any air pushed outside must be replaced by air entering through doors, windows, wall gaps, outlets, and other openings. In hot or humid climates, this replacement air increases the cooling load and can reduce performance.
When the unit is installed outside under cover, the condenser heat is already outdoors. Indoor air can be ducted to the air conditioner, cooled, and returned back into the building. This can create a slight positive-pressure cooling effect, helping reduce hot, humid air infiltration.
Important: If placing the unit outdoors, it must be protected from rain and direct weather exposure. Use only in a covered, dry location with proper electrical power and proper air duct access.
Best Indoor Installation Method
If the unit must be installed indoors, the most efficient method is to duct both the condenser intake and condenser exhaust outdoors.
- Use the optional 8-inch condenser inlet adapter mounted over the front filter.
- Use 12-inch ducting from the top condenser discharge to move hot air outside.
This allows condenser air to enter and leave the unit without pulling hot, humid makeup air through the building envelope. Room air is drawn through the evaporator filter, cooled, and discharged through the two upper 4-inch cold air outlets.

PRINCIPAL OF AIR CONDITIONING
Heat is a form of energy, cooling is means of transferring the heat from one object to another. In the case of Air conditioning, sensible heat is removed from the indoor space and replaced with cooler air, and the warm air removed is exhausted outside the space being conditioned. This process gradually reduces / maintains the inside temperature. Air Conditioning is most commonly used to achieve a more comfortable interior environment, typically for humans or animals. However, air conditioning is also used to cool rooms filled with heat-producing electronic items, such as computer server rooms. Spot Coolers allow the cool air to be directed towards specific objects or people.
EIPL 44+ YEARS OF PROVEN EXPERIANCE
EIPL have for many years designed and manufactured bespoke Air Conditiong systems for the Military and Rail markets. Customers include:- BAE Systems, AirBus, Alstom, Bombardier and many more. The key requirement when designing for these markets is robustness and reliability. This experience has now been used to develop a range of Spot Coolers aimed towards the commercial / Industrial markets.
EIPL BKool RANGE
The EIPL range of Bkool Spot coolers have been sized to provide cooling for all sized applications. All units are powered from a regular NEMA 6-20P 230V outlet or two standard 5-15R 120 volt outlets with optional converter box (see below.) The self contained, “plug and play” equipment allows easy installation, just connect a suitable duct to the outlet and position, preferable outside, alternatively outside the space to be cooled, connect to a suitable power source and adjust the digital thermostat to the desired temperature. As the BKool Spot Cooler cools the air, moisture is also removed. This water is collected in the internal container, alternatively the container can be changed for a high capacity internal condensate pump, allowing the unit to run for long periods unattended. Safety is always an important consideration with EIPL, therefore the BKool range incorporates both High and Low Pressure stats which prevent the unit from running in unsafe conditions. The large diameter robust castors allow the unit to be easily manoeuvred into positioned, and the brake applied to prevent movement during operation.

Questions and Answers:
Q. What is a NEMA 6-20P look like that comes factory installed on the unit?
A.
Q. Can the factory plug be removed and replaced with any other style 240 volt plug?
A. Yes. The 10-30P, 14-30P, 10-50P, 14-50P, L6-20P, L14-30, L10-30P, 6-50P, L6-50P and many more are all acceptable to use.
Q. Which is better, Inside installation VS outside installation?
Q. Which is better: Inside installation or outside installation?
A. Outside installation is generally the preferred option whenever practical.
The portable air conditioner moves approximately 559 CFM (cubic feet per minute) of air through the condenser section and exhausts that air through the dual 4.5-inch directional ducts. During the cooling process, the condenser generates heat that must be removed from the system.
Outside Installation (Preferred)
When the unit is placed outside the building, the heat generated by the air conditioner is already outdoors, eliminating the need to exhaust hot air from inside the conditioned space.
The advantages include:
-
Creates a slight positive-pressure cooling system
-
Reduces infiltration of hot, humid outdoor air
-
Improves overall cooling efficiency
-
Helps keep dust, pollen, and contaminants from entering the building
-
Eliminates the need for additional hot-air exhaust ducting
In this configuration, indoor air is ducted to the air conditioner, cooled, and then returned to the building. This is similar to many commercial HVAC systems that introduce conditioned air into a building, creating positive pressure. You may have noticed air blowing outward when opening the door of a large commercial building—this is a result of positive building pressure.
Important: If installing the unit outdoors, place it in a covered location protected from rain and direct weather exposure. You must also provide:
Inside Installation
When the unit is located inside the building and the condenser air is exhausted outdoors, the building operates under negative pressure.
Because approximately 559 CFM of air is being pushed outside, that same volume of air must be replaced. Replacement air typically enters through:
In most climates, this replacement air is hot and humid, which increases the cooling load and reduces system efficiency.
Best Indoor Installation Method
If the unit must be installed indoors, the most efficient setup is to duct both condenser intake and condenser exhaust air outdoors.
This configuration uses:
With this arrangement, approximately 1,120 CFM of condenser airflow is moved both into and out of the unit without affecting room pressure. The conditioned space remains neutral, preventing the unit from pulling hot, humid outdoor air through cracks and openings.
Meanwhile, room air is:
-
Drawn through the front evaporator filter,
-
Cooled by the system,
-
Delivered back into the space through the two upper discharge hoses.

Bottom Line: For maximum cooling performance and humidity control, place the unit outdoors under cover and duct the return and supply air through the wall. If indoor installation is required, duct both the condenser intake and condenser exhaust outdoors to avoid creating negative pressure inside the building.
