Introducing

WiSAN-YMD1 NA

New WiSAN-YMD1 NA | MODULAR Heat Pump

We are pleased to announce the North American launch of the WiSAN-YMD1 NA series. This next-generation, air-cooled modular heat pump is engineered for outdoor installation, leveraging R32 low-GWP refrigerant and Full-Inverter technology across both compressors and fans to meet the rigorous demands of modern sustainable building design.

Performance at a Glance

The WiSAN-YMD1 NA series delivers a nominal capacity of 28.6 Tons, providing industry-leading efficiency across all operating conditions:

Full Load Efficiency: COP values up to 3.61
Part Load Efficiency: IPLV values up to 18.5

Key Technical Advantages

1. Sustainable Low-GWP Solution

By utilizing R32 refrigerant (GWP = 675), the WiSAN-YMD1 NA reduces environmental impact by two-thirds compared to traditional R-410A systems. This ensures compliance with evolving North American refrigerant regulations while maintaining superior thermal properties.

2. Advanced Inverter Technology

Equipped with dual refrigerant circuits and a sophisticated control suite, the unit features:

Full-Inverter Scroll Compressors: Ensuring precise load matching and reliability.
DC Inverter Fans: Optimizing airflow and minimizing parasitic energy consumption.
Superior Staging: The system tracks building load fluctuations with high granularity to reduce cycling and operational costs.

3. Versatile Acoustic Configurations

To meet stringent local noise ordinances, the series offers three distinct acoustic packages without altering the unit’s physical footprint:

Standard Configuration (SC): Compressor soundproofing – 87 dB(A)
Low Noise (LN): -3 dB(A) reduction vs. SC
Extra Low Noise (EN): -10 dB(A) reduction vs. SC

4. Extended Cold-Climate Operating Limits

Specifically engineered for high-performance heating, the WiSAN-YMD1 NA maintains high leaving water temperatures (LWT) even in extreme environments:

140°F LWT at ambient temperatures down to 25°F
131°F LWT at ambient temperatures down to 3°F
Operational heating down to -13°F ambient (107°F LWT)

5. High Modularity & 4-Pipe Capabilities

Scalability: Connect up to 16 units via LAN (two banks of 8 units), designed for a compact footprint.
Simultaneous Load Management: When paired with the Intelliplant system and integrated 4-pipe kit, the system enables simultaneous hot and chilled water production, optimizing thermal balance across the facility.

Commercial Availability

The WiSAN-YMD1 NA is now available in the Energy Tool for immediate selection, technical validation, and quoting.

Shipping Note: Initial deliveries are scheduled to commence in September 2026. Lead times should be confirmed at the time of order entry.
