2. Burner/Blower Section

Use a crane and a spreader bar hooked to the factory lifting lugs (shown below) to lift and center the unit onto the filter stand section. The sections can be caulked together, but it is not needed with the water kickouts provided with this section.

3. Install Ductwork

This table shows the duct sizes and straight lengths recommended for optimal performance (AMCA Publication 201-90). Using duct sizes less than recommended will affect fan performance. Good duct installation practices should be followed for the remaining ductwork. See the drawings in the Dimensional Data section for duct locations.

A typical horizontal discharge installation is shown. Gas and/or electrical lines can be connected at this time.

For upblast units, a duct elbow may be needed to turn the ductwork into the building. Follow proper ductwork methods recommended by AMCA to make this elbow to minimize duct losses.

VSU specifications

Greenheck Fan VSU, or Variable Speed Unit ventilators, represent a significant advancement in the field of HVAC technology. Designed to enhance air quality and energy efficiency, these units are particularly suited for commercial applications such as schools, offices, and industrial facilities. They provide a reliable solution for both heating and cooling, ensuring optimal comfort and productivity in diverse environments.

One of the hallmark features of the VSU is its variable speed motor. This innovation allows the fan speed to adjust according to the specific demands of the space, leading to substantial energy savings compared to traditional fixed-speed units. By operating at reduced speeds during lower load conditions, the VSU minimizes energy consumption while maintaining comfortable indoor conditions. This adaptive capability not only lowers utility bills but also contributes to a reduced environmental footprint.

In addition to energy efficiency, the VSU is equipped with advanced controls that provide precise temperature management and air distribution. These controls can be integrated into existing building management systems, giving facility managers the ability to monitor and fine-tune operations remotely. The ability to set specific schedules and program temperature settings enhances overall building performance and ensures that spaces are only conditioned when necessary.

The VSU is designed with a robust and durable construction, featuring corrosion-resistant materials that prolong the unit's lifespan. This reliability is further enhanced by its easy accessibility for maintenance, making it a cost-effective solution for long-term use. Users can expect a quiet operation due to the fan’s advanced design, which significantly reduces noise levels compared to traditional models.

Furthermore, the VSU supports a variety of custom configurations, allowing it to meet the specific needs of different applications. Whether it's integrating with other HVAC components or adapting to varied ceiling heights, the flexibility of the Greenheck Fan VSU makes it a versatile choice for engineers and building owners alike.

In conclusion, the Greenheck Fan VSU stands out for its combination of energy efficiency, advanced control options, durability, and adaptability. As the demand for sustainable and effective HVAC solutions continues to grow, the VSU positions itself as a top choice for those seeking to enhance indoor air quality while minimizing operational costs.
