KOLOWA Ventilation Fan & Cooling
This method of cooling is done by installing
a system of high quality wet cooling pads and negative pressure ventilation fans to create an evaporative
cooling and Gsi Wind Chill effect. This will also effectively rid the factory of odor, dust and stagnant
1. After the installation, the combined system
extracts out the high temperature air to reduce the in-house temperature (32-65˚C) sharply and maintaining it
at the most comfortable condition, i.e. between 25-32˚C.
You may find an increase in production
2. It improves the factory ventilation by
3. It saves up to 86% of the costs of equipment
and electricity consumption. Your company will save considerable cost and it helps to achieve your
company’s ROI at a faster rate. Please refer to chart below.*
KOLOWA Negative Pressure Ventilation
Applying the theory of air exchange and air
distribution, this system efficiently removes odor, heat, fumes, dust and stagnant air, while bringing in
fresh air. Taking into account the speed of air flow per second and the number of air change per hour, the
amount of fresh air to be brought in can be accurately controlled.
1. Wall-Mounted Negative Pressure Ventilation
This is the best negative pressure
ventilation system. It significantly improves the factory ventilation efficiency by up to
2. Wall-Mounted Negative Pressure Ventilation System
To prevent the extracted hot air from blowing
directly to the neighbors, the Elbow Type is a good solution to allow the hot air to be discharged either
upward or downward. This is also an environmental-friendly ventilation system. It improves the factory
ventilation efficiency by 85-95%.
3. Roof-Mounted Negative Pressure Ventilation
This system is recommended in case a
wall-mounted negative pressure ventilation system is not possible. This is also an environmental-friendly
KOLOWA Positive Pressure Cooling System
This positive pressure system utilizes air
coolers / water cooling fans. It is also powerful and effective in lowering temperatures for the desired
