LOFlo System
The award-winning TACO LOFlo™ system sets a new standard in comfort, ease of design, and Green Building energy performance for small to large buildings.
LOFlo: Advanced hydronic radiant heating and cooling
The Taco LOFlo System is used in hydronic heating and cooling systems to significantly reduce the flow of water. Typically used in radiant panel (ceiling, wall or floor) and chilled beam (passive and active) applications, the technology significantly reduces pump flows and pipe sizes for reduced energy consumption and lower first costs. The LOFlo System also provides precise control of supply water to the terminal, e.g. chilled beam, and precise control of room temperatures.
