Description
The Tranquility 18 SC Compact Single-Stage Series is a high-efficiency geothermal solution engineered to achieve performance beyond ASHRAE 90.1 standards using Earth-friendly R-454B refrigerant. Designed with a compact cabinet, this unit installs easily in tight spaces while offering flexible configurations for both horizontal and vertical installations. A double-isolation compressor mount, combined with sound-absorbing insulation, ensures whisper-quiet operation, even during start-up and steady state runs. Enhanced with building-management system (BMS) compatibility—including BACnet, Modbus, and Johnson Controls N2—it integrates smoothly into commercial HVAC ecosystems. Optional features like Refrigerant Detection System (RDS), EC motor configurations, and UltraQuiet packages allow customization along with backward compatibility for retrofit applications.
Key Features:
- Half-to-5 ton capacity range (006–060 sizes) for flexible sizing
- R-454B low-GWP refrigerant, exceeding ASHRAE 90.1 efficiency standards
- Double-isolation compressor mounting with acoustic insulation for low noise
- Compact footprint with field-convertible discharge for horizontal or vertical installations
- BMS-ready: supports BACnet, Modbus, and Johnson Controls N2 communication protocols
- Optional Refrigerant Detection System (mandatory on 060, optional on others)
- Choice of Constant Volume (CV) or Constant Torque (CT) EC motors with UltraQuiet package
- Non-corrosive polymer drain pan and robust safety feature set
TL;DR:
- Compact, quiet geothermal unit covering 1/2 – 5 tons
- R-454B refrigerant; exceeds ASHRAE 90.1 efficiency
- BMS-compatible for modern commercial control
- Customizable with EC motors, RDS, and noise-attenuation options
