Integrated Piping System

Two-pipe innovation that transforms building HVAC

Say Goodbye to Seven-Pipe Systems

Williams' next-generation two-pipe system is powered by a building's domestic water supply, providing lower installation costs and higher operational savings—all while eliminating the need for dedicated comfort system piping.

Our two-pipe system is whisper-quiet, reliable, and LEED-friendly. Take advantage of your building's existing piping infrastructure to provide on-demand, 24/7 heating and cooling without the complexity and cost of traditional systems.

Compared to traditional seven-pipe systems, IPS is designed to reduce installation complexity and improve operational efficiency while supporting occupant comfort.

Project Benefits

Phased Openings

Open sections of a building sooner without waiting for time-consuming pipe installation. Our proprietary fan-coil technology utilizes the existing potable water system to provide efficient heating and cooling.

Complete Projects Faster

Our IPS is an auto-calibrated, self-balancing system that can shave weeks off your project time. Complete your project with fewer materials and eliminate the need for noisy compressors.

Lower Project Costs

Enjoy significantly lower building costs by reducing the number of pipes needed from seven to just two. Use our Williams suite of design software for an efficient, cost-saving piping system.

NSF-61 Certified

Fan coils rated for potable water systems, maximizing comfort with units NSF-rated for potable water applications.

LEED-Friendly

Our two-pipe system is whisper-quiet, reliable, and LEED-friendly to provide the ultimate comfort while supporting sustainable building goals.

24/7 Heating & Cooling

Take advantage of your building's existing piping infrastructure to provide on-demand, around-the-clock heating and cooling.

Technology

TRACvalve

Valuable performance at a fixed cost

The TRACvalve variable fan coil is a budget-friendly, cost-efficient solution to increase comfort through air temperature control. The system's central pumps use less horsepower to provide heating and cooling while improving central plant efficiency.

TRACvalve adjusts to the design LAT, maintaining a high Delta-T across the coil. Variable fluid flow reacts to room and system changes, reducing the GPM at load mode demand.

Technology

ComforTRAC

A totally variable fan coil

The ComforTRAC recognizes changing room conditions and adjusts automatically, matching real-time variable load in virtually any indoor environment. Since moving BTUs in water is superior to moving them in air, the result is higher comfort with lower system costs and greater energy efficiency.

The totally variable fan coil offers variable CFM, GPM, LAT and dehumidification. Ideal for classrooms, conference rooms, dorms, suites, and any space where discriminating occupant demand for comfort is required.
