Water/air heat pump SmartSource®

R32eco-friendlylow greenhouse gases

Product overview
SmartSource® Vertical Stack water-source heat pumps (WSHP) are engineered for multi-floor residential and commercial buildings including apartments, offices, hotels, and nursing homes. Available in 1/2 to 3 ton capacities (sizes 009–036), units come as full cabinet models for new construction or stand-alone chassis for fast replacement. The product line uses low‑GWP R‑32 refrigerant and incorporates design elements for quiet, efficient, and serviceable operation.

Models

• WSVF
• WSVC

Quick Installation & Service
Multiple discharge air arrangements, a compact footprint and extended‑riser piping simplify floor‑to‑floor installation and reduce on‑site labor. A factory‑installed hydronic heating coil option is available to enhance energy performance and reduce field work.

Multi-floor Solutions
SmartSource vertical stack WSHPs with low‑GWP R‑32 refrigerant are designed as cost‑effective, stackable HVAC solutions for high‑rise apartments, condominiums, hotels, new construction, retrofit projects, and geothermal systems.

Standard or Geothermal Applications
Units are engineered for high efficiency with flexible configurations to support standard hydronic or geothermal heating applications.
