～ Bringing Safety and Comfort to All Extreme Heat Sites ～
In environments where conventional cooling systems cannot solve the problem or where cooling efficiency is poor, COOLEX can provide heat stroke protection and work efficiency.
Cools down the wearer's body by circulating cold water at approximately 10℃
COOLEX effectively cools the body of workers in extremely hot sites by circulating cold water inside the dedicated clothing.
The personal type is portable and easy to install.
COOLEX personal type can be used anywhere on site where AC power is available.
Product Features
It cools down forever (endless).
The wearer's preferred temperature can be set.
Suitable for work where wind is not allowed.
It is also effective for work with protective clothing over the entire body.
Cool people without cooling large spaces.
Wasted energy is generated to cool large spaces.
It was not practical, especially at sites with heat-generating work.
In contrast, COOLEX is "efficient" and "effective" because it cools only the worker in the site.
Ideal for extremely hot sites with ambient temperatures of 40 to 50℃
Because it does not generate wind, it is also ideal for use in extremely hot environments where wind is not preferred, such as powder, painting, and welding operations.
High cooling effect with low running cost
Excellent energy-saving performance with power consumption of only 180W per person (COOLEX-1).
High cooling effect that is as good as air conditioners.
As a comprehensive manufacturer of industrial ventilation systems, KAMAKURA is constantly in pursuit of the ideal ventilation system.
Sales of our flagship product, the "Roof Fan," have already surpassed 1 million units in Japan.
We respond to the diverse ventilation needs of factories and offices with our extensive lineup and solid proposal capabilities.
Trust of 1 million units to all plants and offices
The "Roof Fan" is a best-selling rooftop ventilation fan created by combining KAMAKURA's half-century of industrial ventilation equipment technology and know-how.
A full lineup of products is available to meet the various ventilation needs of factories and offices.
Main applications
Forced exhaust
There is an extensive lineup of products in this category.
The system can be installed in a wide variety of factories and offices, including general factories, experimental laboratories, cleaning factories, food and drug-related establishments, chemical plants, and other special factories where explosive gases are generated.
Fforced air supply
To achieve a comfortable ventilation plan, the air supply must match the exhaust air volume.
In addition, the airflow formation of the air supply can create a cooler experience. We have a full lineup of forced air supply systems.
Natural ventilation
Roof fan casing used as natural ventilation opening.
Suitable for ventilation in buildings where constant ventilation airflow is not required or in buildings with strict noise restrictions.
It can also be used for natural ventilation of hazardous material warehouses, high-heat local exhaust stacks, and other applications.
Cubic type
Kamakura's original cubic design combines curves and straight lines.
Its rational shape harmonizes with all types of roofs.
Four different body materials available
Hot-dip galvanized steel sheet, aluminum, FRP, stainless steel
Backflow prevention flap
A unique backflow prevention flap that closes the air outlet during strong wind and rain to prevent wind and rain from blowing in.
(Adopted for cubic type only)
As a comprehensive manufacturer of industrial ventilation systems, KAMAKURA is constantly in pursuit of the ideal ventilation system.
Sales of our flagship product, "Roof Fan," have already exceeded 1 million units, and based on our accumulated experience, we have also succeeded in developing the revolutionary "Cool Roof Fan," an air supply system that will change the concept of factory ventilation.
Cool Roof Fan and Roof Fan realize "Cool Air Supply x Optimum Exhaust" and introduce a new concept of coolness.
Cool Air Supply x Optimum Exhaust Mechanism
Cool Roof Fan supplies a large amount of cool air and Roof Fan exhausts hot air powerfully
→Unprecedented coolness with cool breeze and air flow
Cool breeze for cool comfort
Cool Roof Fan is an air supply unit with a built-in cooling element that uses the vaporization heat action of water. It converts hot outdoor air into cool, refreshing air.
Comfortable airflow with large air volume
The combination of large-volume cool air supply and powerful exhaust air forms a comfortable airflow. The airflow also delivers a pleasant coolness to the work area.
*Outside temperature 34°C, relative humidity 55%.
Cool Roof Fan blowing temperature ⇒ 27°C
(Relative humidity at the air outlet will be approximately 90%.)
Excellent cost performance
Running cost is 1/4 or less compared to industrial air conditioners. Cost saving compared to air conditioner-based ventilation plans!
Smooth replacement work
For compatibility, Cool-Roof Fans and Roof Fans share the same dimensions of their mounts. Replacement work is smooth.
Space-saving & non-fluorocarbon design
The space-saving design allows the unit to be blown down from the rooftop, eliminating the need for a dedicated machine room. Furthermore, the system does not use refrigerant gas, making it environmentally friendly.
It is also ideal for environments where it is difficult to install air conditioning.
Even in factories and offices where air conditioner-based ventilation planning is difficult, "cool air supply x optimum exhaust air" can provide heat protection.
Ex: Factories and offices where large amounts of heat are generated
Factories and offices that need to improve the environment in large spaces
Factories or offices where air conditioning is too costly
Factories/offices that need to replace some of their exhaust fans
Cool Clean Fan Effectiveness
Cooling effect
Cool Clean fan incorporates a cooling element with numerous elongated air pathways.
When outside air comes in contact with the water-covered element, the water vaporizes and removes heat.
The vaporization heat action of water creates a cool breeze.
Air purification effect
Cool Clean Fans have the ability to remove particulates along with their cooling effect.
Atmospheric particles collide with water flowing over the cooling elements and flow down into the main unit's water storage tank in the water stream.
Therefore, unlike general air conditioning filters, there is no pressure loss due to clogging.
Cool Breeze Effect
According to data published by the Japan Meteorological Agency, summer noon in Japan is hot and humidity drops to 40% in some areas.
This low humidity greatly reduces the temperature of the cool air from the outdoor air temperature, maximizing the effect at the time of day when coolness is desired.
positive pressure
To make the work space comfortable, it is effective to actively exhaust hot air generated during work at the same time as supplying fresh air.
However, if the air is exhausted too much, the air pressure inside the building becomes lower than that outside, and insects, dust, etc. can easily enter through windows and doors.
If a large amount of cool air is supplied by Cool Clean Fan, the negative pressure inside the building can be eliminated, and this helps prevent entry of hot air, insects, dust, etc. through gaps.
Energy-saving design
The only power consumed by the Cool Clean Fan is the fan and pump.
Since no compressor or condenser is used, the system has outstanding COP (energy consumption efficiency) and reduces CO2 emissions, a cause of global warming.
COP is 4 to 5 times higher than that of a typical industrial air conditioner.
Powerful blower that is useful in various scenes on site, from heat protection, product cooling and drying, fume control, and circulation.
Product Features
Powerful, highly directional, high airflow blower
Versatile for heat stroke prevention, ventilation promotion, fume control, product cooling and drying, and other applications in factories
Energy-saving type, extra-large airflow type, low-noise type, etc. 13 types of rich lineups
The product name has been changed to "Blue Jet Fan" to evoke an image of high air volume and powerful airflow for the first time in the last half century since its launch. (Former product name: GYM Fan)
"When the product was first released (around 1970), it was named ""GYM Fan"" because it was designed for school gymnasiums, but after improvements and improvements, it was mostly designed for factories, and only the product name has remained unchanged since then.
Since many customers misread the name as ""GYM Fan"" and some said they did not understand the meaning of the product name, we have decided to change the product name to give a clear image of the product functions."
Please note that there will be no change in the product itself (appearance, performance, price, etc.), only in the product name.
Origin of "Blue Jet Fan"
Based on the fact that it is recognized as a "blue fan" because of its blue appearance, the name is a combination of "Blue," which represents the image of the sky and the sea, and "Jet," which conveys the impression of large air volume and powerful airflow, and is a fan that plays an active role in creating a comfortable working environment.
