Modular Energy Transfer Skids
SiFi Engineering & Fabrication provides Engineered District Energy Solutions through modular Energy Transfer Skids (ETS) designed to efficiently connect buildings and facilities to District Heating and cooling networks.
Our systems act as the interface between the district energy loop and individual buildings, enabling reliable transfer of thermal energy while maintaining hydraulic separation, system control, and operational efficiency.
Through integrated engineering, fabrication, and modular system design, SiFi delivers optimized packaged ETS and TDS (Thermal Distribution) systems that simplify installation, reduce construction timelines, and improve overall energy network performance.
What is an Energy Transfer Skid?
An Energy Transfer Skid (ETS) is a prefabricated modular system that transfers thermal energy from a district energy network to a building’s heating or cooling system.
These skids typically include:
• Plate heat exchangers
• Circulation pumps
• Control valves
• Energy metering systems
• Expansion and pressure control equipment
• Instrumentation and controls
By isolating building systems from the main district loop, ETS systems allow efficient heat transfer while protecting the district network and maintaining precise temperature control.
Modular District Energy Interface Systems
SiFi designs and fabricates modular Energy Transfer Skids that arrive at site fully assembled, tested, and ready for installation.
Key advantages include:
Reduced installation time
Factory assembled skids minimize on-site construction.
Improved quality control
All piping, valves, and instrumentation are assembled and tested in a controlled fabrication environment.
Compact system footprint
Modular design allows efficient use of mechanical room space.
Scalable infrastructure
Systems can be designed to support expanding district energy networks.
Applications
SiFi Energy Transfer Skids support a wide range of district energy applications, including:
• District heating systems
• District cooling networks
• Campus energy systems
• Multi-residential developments
• Commercial building clusters
