What is the ClearAir® Air-to-Water Heat Pump?

The ClearAir® AW0320 is a high-performance, energy-efficient air-to-water heat pump engineered specifically for hydronic heating applications. Using an electrically powered vapor-compression cycle, it extracts heat from outdoor air and transfers it into system water delivering reliable, sustainable heating with significantly lower environmental impact than traditional gas, oil, or electric boilers.

Key Features:

  • Zero onsite emissions and no fossil fuel consumption

  • Delivers high-temperature hydronic heating up to 176°F (80°C)

  • Factory-assembled, monobloc outdoor design for simplified installation

  • Uses R-513A low-GWP, A1-classified refrigerant (safe, low environmental impact)

  • Integrated touchscreen controller with single, multi-unit, and hybrid system logic

  • Compact footprint with minimal mechanical room impact

ClearAir® Air-to-Water-Heat-Pump

Purpose-Built for Hydronic Heating

The ClearAir is engineered specifically for hydronic systems not adapted from comfort cooling equipment allowing it to meet demanding commercial water temperatures up to 176°F (80°C) for coils, radiators, fan coils, and terminal units. This enables upgrades to existing systems without replacing downstream equipment.

Environmentally Responsible Refrigerant

R-513A refrigerant is classified as A1 (low toxicity, no flame propagation) and has:

  • 0 Ozone Depletion Potential
  • 573 Global Warming Potential, far lower than legacy refrigerants like R-134a at 1430
  • This meets the EPA's 2025 refrigerant guidelines and reduces long-term environmental impact.

Simple, Scalable System Design

Whether serving a small building or a multi-facility campus, the ClearAir supports:

  • Single-unit installations for dedicated loads
  • Multi-unit banks for higher capacity and redundancy
  • Hybrid systems that integrate with boilers to balance carbon reduction and reliability in cold climates
  • This flexibility lets engineers right-size systems for efficiency and budget.

Smart, Integrated Controls

Each unit includes a factory-programmed controller to manage:

  • Compressor and fan sequencing
  • Electronic expansion valve
  • Defrost mode (hot gas bypass)
  • Lead-lag control across multiple units
  • Hybrid logic with boilers
  • BMS integration via BACnet or Modbus

 

Plus, it can connect to Prometha® for remote monitoring. 

Why Heat Pumps Are Becoming Essential

  1. Lower Emissions & Sustainability Compliance Heat pumps produce zero onsite emissions, helping building owners:
    • Meet local and national decarbonization goals
    • Comply with regulatory changes
    • Support corporate ESG initiatives
    • Reduce fossil fuel consumption
  2. Reduced Operating Costs Over Time With a COP of 2.7, the ClearAir produces more heat output per unit of electricity consumed—delivering long-term operating savings compared to traditional electric or fossil-fuel boilers.
  3. Ideal for Electrification & Retrofit Projects High-temperature hydronic output means the ClearAir can support existing buildings without redesigning the entire heating loop, making electrification more achievable for complex facilities.
