Heating pump ventilation & cooling Project
Project Overview:
Energy**** HVAC.LLC, a key player in the HVAC industry, approached us to enhance the performance of their heating pump systems. The objective was to integrate a highly efficient and durable axial fan motor that could operate reliably under extreme environmental conditions while meeting their specific technical and operational requirements.
Challenges:
The primary challenge was to develop a fan motor solution that could withstand harsh operating conditions, including wide temperature and humidity ranges, while maintaining high efficiency and reliability. The specific requirements for the fan motor included:
- ● Voltage: 400V (Operating voltage range: 304-456V)
- ● Current: 4.96A
- ● Power Consumption: 1694W (Maximum input power: 2400W)
- ● Airflow: 29373 m³/h (17278 CFM)
- ● Speed: 1075 RPM
- ● Insulation Class: F
- ● Protection Type: IP54
- ● Lifespan: 40,000 hours (at 40°C, 15-65% RH)
- ● Speed Control: 0-10VDC input, with an option for RS485 external control box connection
- ● Electrical Protections: Current limiting, over-temperature, over-current, and locked-rotor protection
- ● Operating Conditions: Temperature range: -30 to 60°C, Humidity: 30 to 95% RH, Altitude: <1000m
Given these stringent requirements, the motor needed to ensure long-term reliability, energy efficiency, and adaptability to both horizontal and vertical installation configurations.
Solution:
We recommended the EC MOTOR Inline Duct Fan with Intelligent Control, which is specifically designed for ventilation in grow tent applications. This product comes in two models—6-inch and 8-inch duct sizes—each tailored to meet different airflow requirements while ensuring minimal noise impact.
