In Nyack, New York, a once-abandoned bowling alley has been transformed into 26 luxury condos. With this conversion came the challenge of designing a reliable HVAC system that could handle modern requirements while protecting critical components.
For the building’s VRF system, lineset protection was a top priority, and Valley Mechanical Services turned to Slimduct RD from Inaba Denko America to meet the unique demands of this project.
Why Lineset Protection Matters in Commercial Spaces
When you work on multi-unit commercial projects, linesets carry the vital refrigerant that powers heating and cooling systems. Left exposed, they are vulnerable to UV damage, extreme weather, and physical impact. In this Nyack project, the linesets ran through shafts connecting three floors and across rooftops with high foot traffic, making durability critical.
Using a reliable product like Slimduct RD helps you protect copper lines and insulation from sunlight, high temperatures, snow, and even human traffic from inspections or maintenance. By choosing a rigid and durable cover, your linesets remain intact, functional, and visually neat.
How Slimduct RD Handled Complex Project Requirements
For the Nyack condos, the building design included rooftop solar panels and compact shaft ways. This required careful routing of the VRF lines. Slimduct RD stood out because it provides:
- UV resistance: Protects insulation from sunlight, preventing early degradation.
- Rigidity: Keeps lines secure, even under foot traffic or maintenance activities.
- Temperature resilience: Withstands rooftop heat above 100°F and cold winters with heavy snow.
You can count on Slimduct RD to maintain lineset integrity while allowing flexibility for building-specific challenges. The product’s strength made it possible to install 26 units efficiently without compromising the rooftop design or the system’s performance.
