The new Davis Center at Harlem Meer is one of NYC's most innovative sustainable buildings. It's tucked into the landscape with the park extended over the roof, using thermal mass and passive cooling to reduce energy demand.

Difficult to access
"The new recreation facility is tucked into the landscape, extending the park over the roof and providing thermal mass and passive cooling."
Key design features include:
Building massing optimized for thermal comfort in all four seasons
Park extended over the roof for thermal mass
Passive cooling strategies to reduce mechanical loads
Integration with the surrounding landscape
"Tucked into the landscape" means mechanical systems are buried and hard to reach. Heat pumps in basements, heat exchangers in confined rooms, and equipment that's difficult and expensive to maintain.
Once buried, accessing heat pumps for maintenance requires excavation or major disruption to the landscape above.
Tight mechanical rooms make regular cleaning and descaling nearly impossible without equipment removal.
Mechanical spaces stay hot, and hot environments accelerate scale formation on heat transfer surfaces.
When equipment is hard to reach, maintenance gets deferred. Scale builds up, efficiency drops, and failures become inevitable.
The question for the Davis Center: Will they have to excavate the park to access the heat exchanger? Or will they install permanent, maintenance-free scale prevention during construction?
Location: China
Building Type: Commercial office tower
The Challenge: Four heat exchanger systems in the building needed scale treatment. But there was a critical constraint: the hot water supply could not be interrupted. The building needed a solution that would work without shutting down operations.
Four Vulcan S10 units were installed to gently clean the heat exchangers and the whole piping system. The key benefit: installation happened without stopping the machines and without interrupting hot water service.
Four heat exchangers protected simultaneously
Zero interruption to building hot water supply
Gentle cleaning without shutting down equipment
No chemicals, no salt, no ongoing maintenance
Why This Matters for the Davis Center: The Taikang Financial Tower proves that heat exchangers can be protected without interrupting building operations. For the Davis Center, where mechanical systems are buried and hard to access, this matters even more. Installing Vulcan during construction means never having to excavate the park for scale-related maintenance.
Passive design reduces energy demand, but it doesn't eliminate mechanical systems entirely. Those systems still need protection.
Even with passive cooling, heat pumps handle peak loads. Their heat exchangers need protection.
Passive design doesn't heat water. Those systems scale just like any other building.
Air handling units with cooling coils need clean surfaces for efficient dehumidification.
The paradox: the more passive the design, the harder it is to access and maintain the active systems that remain.
If a heat exchanger scales up and needs cleaning, you're digging up the park. That's expensive and disruptive.
When scale causes equipment failure, replacement means crane lifts, demolition, and reconstruction of the landscape above.
You can't easily check delta-T on a heat exchanger buried under tons of soil and landscape.
Without regular monitoring, scale builds until efficiency drops dramatically and emergency action is required.
When you bury your mechanical systems, you need to be absolutely certain they won't need maintenance. Vulcan provides that certainty.
Sample ROI Calculation (Buried Mechanical Systems)
Cost to excavate and access buried heat exchanger | $50,000 - $200,000+ |
Heat exchanger replacement cost | $30,000 - $150,000 |
Facility downtime during repairs | Days to weeks |
Vulcan S10 (installed during construction) | |
Future excavation avoided | 100% |

Application | Typical Equipment | Recommended Model | Pipe Size | Flow Rate |
|---|---|---|---|---|
Heat exchangers (small) | Domestic hot water, small hydronic loops | Up to 3" | 65 GPM | |
Heat pumps (residential scale) | Small commercial, multifamily | Up to 4" | 130 GPM | |
Central heat pumps (commercial) | Large hydronic systems, central plants | Vulcan S50 or S100 | 5-6" | 300-530 GPM |
For projects like the Davis Center, the time to include scale prevention is during design, not after construction when equipment is buried.
1
Include Vulcan in MEP specifications. Size for all heat exchangers.
2
Install during build-out. Easy access before equipment is buried.
3
Document baseline performance. Set efficiency benchmarks.
4
Zero maintenance, sustained efficiency, no excavation needed.
The best time to prevent scale is before you bury your equipment.
About Waslix and Vulcan Technology
Waslix provides non-chemical, maintenance-free scale prevention using Vulcan technology. All Vulcan units are secured via our specialized anchor mounting system, providing a permanent, vibration-resistant fit for industrial pipes. Vulcan uses custom-tailored impulse bands to treat water flow electronically, preventing calcium and magnesium from forming hard deposits while leaving the water's chemical composition unchanged.
Pipe diameters from ½ inch to 40 inch
Works on every pipe material: iron, inox, copper, stainless steel, galvanized iron, plastic, PVC, PE-x, hose, compound pipes
Fully cast in acrylic for optimal quality endurance
Do-it-Yourself installation without cutting pipes
Zero salt, zero chemicals, zero maintenance
Identify all heat exchangers. Include heat pumps, chillers, DHW systems, and hydronic loops.
Assess accessibility. Which equipment will be hard to reach after construction?
Include Vulcan in MEP specs. Size units based on pipe diameter and flow rate.
Plan for installation. Install during construction before equipment is buried.
Document baseline performance. Set benchmarks for future monitoring.
Coordinate with commissioning. Ensure Vulcan is included in system verification.
