Paul Reilly Company - Industrial Fans/ Serco® High Volume Low Speed Fans

Serco’s High Volume Low Speed fans are designed to provide an energy-efficient solution for large spaces. Using the laws of physics and aerodynamics, HVLS fans require much less energy than traditional HVAC systems, and provide year-round employee comfort and temperature control.

A Timeless Concept with Cutting-Edge Technology

A Better Fan for a Better Bottom Line
Serco HVLS fans are designed to be the most functional and durable high volume low speed fans in the industry. The large, slow moving air mass produced by Serco HVLS fans circulates air more efficiently and provides considerable benefits:

Keeps employees cool and comfortable
- The 2-3 mph breeze created by Serco fans delivers the equivalent of a 7-11 degree decrease in perceived temperature
- Research supports that increased employee comfort can result in improved productivity and safety
Reduces energy consumption
- Working with the HVAC system, Serco fans help regulate temperature from ceiling to floor, which can allow a facility to raise its thermostat setting 3-5 degrees. This creates a potential energy savings of 4% per degree change
Protect product integrity
- Air circulation helps keep food and produce dry and fresh, reducing potential for decay or spoilage
- Air circulation reduces stagnant air, hot and cold spots and condensation
- Serco fans are also designed to operate in reverse, which helps de-stratify air in refrigerated applications
Improves general working conditions
- Floor condensation is minimized, keeping floors drier and safer for foot and motorized traffic
- Improved indoor air quality through the dispersing of fumes
- Fans can be operated from a centralized location (iFAN™ option), allowing a facility to easily monitor fan activity and performance

Description	N/A Designed specifically to create a comfortable environment using the least amount of energy, the Serco Velocity fan produces a large column of air to efficiently circulate the space and regulate the temperature of large facilities. The Velocity is suitable for a variety of environments, and its flexibility enables year-round savings.	N/A Our Velocity-PV (Photovoltaic) model takes the technology of an HVLS fan one step further by adding the environmental and energy-efficient benefits of solar power. The proprietary design and auxiliary power capability creates a stand-alone operating system capable of working in nearly any climate. Even better, the Velocity-PV does not sacrifice its effectiveness in controlling the temperature of large spaces - in fact, our 18’ ( 5.5 m) diameter Velocity-PV puts out more airflow than some competitors’ conventional 24’ (7.3 m) fans. Renewable energy and low carbon footprint combine to provide years of reliable performance while supporting the environment and your company’s bottom line.	N/A The Tilt is designed for spaces where ceiling height, sprinklers or ground obstructions may prevent the use of traditional HVLS fans. Small and powerful, the Tilt uses the same physics principles and technology of HVLS fans to produce a non-turbulent airflow of up to 26,432 cubic feet of air per minute, and costs less than 25 cents per day to operate. Its versatile structure allows strategic placement for optimal airflow, providing an energy-efficient replacement or supplement to traditional HVAC systems.
How Does An HVLS Fan Work	N/A The patented airfoils (blades) on the Serco VELOCITY fan produce a massive, cylindrical column of air that flows down to the floor and outward in all directions. This "horizontal floor jet" pushes air a greater distance before it begins moving vertically and is drawn back through the fan. The greater the down flow, the greater the air circulation and resulting benefits. In cooler months, the VELOCITY fan can operate in reverse, circulating hot air trapped at ceiling level and creating a warmer mix of air throughout a facility.
Proven Technology / Stand-Alone Package	N/A	N/A The Velocity-PV utilizes solar power components that have been proven reliable in other applications for over a decade. Three 185-watt mono-crystalline solar panels generate more than enough energy to run the Velocity-PV fan and mount on the roof using either non-penetration or penetration style mounting systems. The solar charge controller, custom wiring loom with service disconnect, and remote control all ensure consistent operation, and the optional auxiliary backup powered system provides additional assurance that the Velocity-PV will remain operational in low sunlight situations. Companies are strengthening their commitment to sustainability and demonstrating the importance of energy savings, renewable energy and green building as part of their overall sustainability initiatives.
