Thermafit™ Modular Water-Source Multi-Pipe

Model MWS

Trane Thermafit™ MWS Water-Source Multi-Pipe modular chillers

Overview

Modular heat pump chiller for flexible, reliable comfort.

Thermafit™ MWS offers scalable design, simultaneous heating/cooling, and operational redundancy for optimal performance and reliability in multi-pipe systems.

  • Capacity: 
    • 30-60 ton modules (432-842 MBH)
    • 3-10 modules per bank
  • Application: Simultaneous cooling and heating
  • Compressor: Tandem-set fixed-speed scroll
  • Refrigerant: Next-gen, low-GWP R-454B

  1. Modular Design for True Flexibility

    The Thermafit™ MWS Multi-Pipe features a modular design, allowing for easy scalability and customization to meet specific application needs. This flexibility ensures optimal performance and adaptability, making it ideal for various water-source multi-pipe systems.

  2. Simultaneous Heating and Cooling

    With the ability to provide simultaneous heating and cooling, the Thermafit™ MWS optimizes comfort year-round. Independent setpoints for heating and cooling ensure precise temperature control, enhancing efficiency and reducing energy consumption.

  3. Operational Redundancy for Reliability

    The Thermafit™ MWS bank of modules creates operational redundancy, ensuring continuous performance even if one module fails. This feature enhances system reliability and minimizes downtime, providing peace of mind for critical applications.

FAQs

Your questions about modular water-source multi-pipe systems, answered.

Multi-pipe systems can provide 100% cooling, 100% heating, or simultaneous heating and cooling, allowing bank to control to independent chilled water and hot water setpoints. These systems have 3 fluid loops - cooling, heating, and geothermal.

During cooling mode, modules operate as standard water-cooled chiller and reject heat to the geothermal loop. In heating mode, modules reverse refrigerant flow and act as a water-source heat pump, extracting heat from the geothermal loop. In simultaneous mode, waste heat is captured from cooling cycle and repurposed to produce hot water.
