Since 1980, more than 19,000 Zomeworks single axis trackers have been installed, in different climates, on nearly every continent in the world. Track Racks™ are highly cost-effective components for domestic and industrial photovoltaic power systems; water pumping systems; cathodic protection systems; and traditional power utilities.
ZOMEWORKS UNIVERSAL TRACK RACK
Module Space: 120 ft2
Manufacturer Part Number: UTRF-120
Incorporating over three decades of tracker design and fabrication experience, the UTRF Series Tracker is our most popular design for large arrays. It features sturdy welded-steel construction, pre-assembled bolt-together components, sealed-axle ball bearings, heavy-duty shock absorbers, and early morning wake-up fin to catch the first sunlight of the day. Our UTRK-040 and our UTR-020 are perfect for small PV systems and pumps.
Six standard UTR and UTR-F Track Racks fit all common photovoltaic modules
SIMPLICITY AND ELEGANCE
The sun’s heat moves liquid from side to side. This action allows gravity alone to turn the Track Rack to follow the sun—therefore no motors, no gears and no controls to fail.
The Track Rack features an early morning, rapid-return system. Shipped partially assembled, it’s easy to install and is module specific.
Six standard UTR and UTR-F Track Racks fit all common photovoltaic modules. The UTR020, UTRK040 and the UTRF072, -090, -120 and -168 are named for the number of square feet of module area they hold. To determine which size single axis tracker you need for your modules, see the Spec Sheet.
EASY TO TRANSPORT
The Track Rack is broken down and packed into one to five boxes (depending on the size of the rack).
All Track Racks are warranted for 90 mph winds 3 second gusts.

Zomeworks Track Racks increase electrical output of photovoltaic modules by 25% or more compared to modules on fixed mounts. A 12-module tracking system delivers the same electric output as 15 modules mounted on fixed racks – a savings of three modules. Track Racks are highly cost-effective components for domestic and industrial photovoltaic power systems, water pumping systems, cathodic protection systems, and utility applications.
SIX SIZES FIT ALL
Zomeworks UTR-020, UTRK-040 and UTRF Series combine the ingenuity, dependability, and practicality that represent Zomeworks’ products with a universality of application that reduces the cost and simplifies the installation of solar systems. Our six standard sizes hold 2-16 modules. All Universal Track Racks will accommodate most PV modules on the market. These trackers come packaged as a kit with all hardware and instructions for quick assembly.
HOW THE UNIVERSAL TRACK RACK FOLLOWS THE SUN
The UTR begins the day facing west. As the sun rises in the east, it heats the unshaded west-side canister, forcing liquid into the shaded east-side canister. As liquid moves through a copper tube to the east-side canister, the tracker rotates so that it faces east.
The heating of the liquid is controlled by the aluminum shadow plates. When one canister is exposed to the sun more than the other, its vapor pressure increases, forcing liquid to the cooler, shaded side. The shifting weight of the liquid causes the rack to rotate until the canisters are equally shaded.
As the sun moves, the rack follows (at approximately 15° per hour), continually seeking equilibrium as liquid moves from one side of the tracker to the other.
The rack completes its daily cycle facing west. It remains in this position overnight until it is awakened by the rising sun the following morning.
