This project is located in Ulaanbaatar, Mongolia, where winter temperatures can drop to -40°C. The customer needed a reliable fresh air supply solution for a commercial apartment building. In such an extremely cold climate, the ventilation system must not only deliver filtered outdoor air, but also address winter-specific challenges such as cold air backflow, low-temperature operation, and heat loss.
Based on the standard CYCSFP FA150 filtered supply fan, Cycair provided a customized solution with electrical heating, a motorized air damper, and enhanced thermal insulation to better match the project’s low-temperature operating conditions.
Commercial apartment buildings require stable fresh air supply to improve indoor air quality, reduce stale air, and provide a healthier indoor environment for occupants. However, in a city like Ulaanbaatar, fresh air ventilation becomes much more challenging during winter.
Outdoor air is extremely cold, and if a standard fresh air unit is used without special protection, the system may face problems such as:
For this reason, the customer needed a ceiling-mounted filtered supply air unit that could operate more safely and reliably in a severe winter environment.
Ulaanbaatar is known for its long and harsh winters. The ventilation unit must continue to operate under very low ambient temperatures and help reduce the discomfort caused by cold incoming air.
When the fresh air unit is turned off, outdoor cold air may flow backward through the duct into the indoor space. This can significantly reduce indoor comfort and increase heating energy consumption.
In cold-climate applications, standard ventilation equipment may need improved insulation performance to reduce heat loss and maintain more stable operation.
As a commercial apartment project, the building still needs filtered fresh air to improve indoor air quality for daily occupancy.
For this project, Cycair recommended the CYCSFP FA150 Filtered Supply Fan, a compact ceiling-mounted fresh air supply unit designed for residential and light commercial applications.
To adapt the unit to the project’s cold-climate requirements, Cycair upgraded the standard product with several customized features:
This customized configuration helped the customer achieve safer and more reliable fresh air supply in an extremely cold environment.
The CYCSFP FA150 is a ceiling-mounted filtered supply fan designed to provide clean outdoor air to indoor spaces. It is suitable for apartments, residential rooms, and light commercial projects where filtered fresh air supply is needed.
For this Mongolia project, the unit was specially customized for winter operation.
An electrical heater was added to the unit to help warm the incoming outdoor air during winter.
When the outdoor or incoming air temperature drops below 0°C, the electrical heater can be activated. The start temperature can also be set according to project requirements, giving the customer greater flexibility based on actual site conditions.
This function helps:
A motorized damper was added to the unit to prevent outdoor cold air from flowing backward into the building when the fan is not running.
This is especially important in winter applications. When the system stops, the damper closes automatically, helping to:
To better match the severe climate in Ulaanbaatar, the unit was also upgraded with enhanced insulation performance.
Better insulation helps reduce heat loss from the unit and duct connection area, which is especially valuable in low-temperature applications. It also supports more stable and energy-conscious operation during the winter season.
The CYCSFP FA150 already offers several features that make it suitable for fresh air supply projects:
After customization, the product became even more suitable for cold-climate ventilation projects in places like Mongolia.
With the customized CYCSFP FA150 solution, the customer gained several practical benefits:
The system is better prepared for winter operation in a severe climate environment.
The electrical heating function helps avoid direct delivery of excessively cold outdoor air.
The motorized damper helps stop cold outdoor air from entering the indoor space when the system is off.
Improved insulation and controlled airflow help reduce unnecessary heat loss.
The filtration system supports better indoor air quality for apartment occupants.
This project shows that in very cold regions, a standard fresh air supply unit may need project-based customization. For markets such as Mongolia, Russia, Central Asia, Northern Europe, and other cold-climate regions, features like electrical heating, motorized dampers, and enhanced insulation can be very important.
Instead of simply supplying outdoor air, the ventilation system must also be designed to handle:
Cycair can support this kind of project with both standard products and customized solutions.
For this commercial apartment project in Ulaanbaatar, Mongolia, Cycair customized the CYCSFP FA150 filtered supply fan to meet the challenges of extreme winter conditions.
By adding electrical heating, a motorized air damper, and improved insulation, the solution became more suitable for reliable fresh air supply in a -40°C cold-climate environment. This project demonstrates Cycair’s ability to adapt standard ventilation products to real project conditions and provide more practical solutions for international customers.
If your project requires a filtered supply fan with electrical heating, a fresh air unit for cold regions, or a custom ventilation solution for apartments and commercial buildings, Cycair can help.
