Packaged Chillers, Central Chillers, New Controller for TCUs

Sterling is unveiling a series of new products for temperature control at NPE2024. These include packaged chillers, central chillers and a new control interface for its TCUs.

GPL Packaged Chillers: Sterling has completely redesigned its line of packaged chillers with significant improvements for processors. The GPL packaged chillers are available with two refrigerant choices — R-410A or R-454B. R-454B is a “Low GWP” (Global Warming Potential) refrigerant that meets new environmental requirements of 12 U.S. states which went into effect Jan. 1, 2024. The GPL has a controller with a new color touchscreen for simple operator use. The new product design enables much easier access to components for regular maintenance. The GPL has a wide variety of option choices, but also has many items now included as standard, such as an audio/visual alarm. The new GPL is available as both air- and water-cooled models for 5- to 60-ton cooling needs.

New GPL Small-Packaged Chillers: These GPL chillers (photo) use R-513A refrigerant. R-513A is a “Low GWP” refrigerant which meets new environmental regulations. This refrigerant is also classified as nontoxic and nonflammable, similar to the R-134A and R-410A it replaces. The units use an air-cooled system and have many features included as standard such as an audio/visual alarm. The new GPL chillers are available in 1-, 2- and 3-ton cooling capacities.

New LHE Central Chillers: Like the new GPL packaged chillers, the LHE central chiller offers customers two refrigerant options — R-410A or R-454B. The LHE continues to offer the central chiller’s key benefits of high efficiency and modular expandability. The LHE is available in 20 to 60-ton cooling sizes.

New Touchscreen controller for TCUs: The new Sterling TS-5 controller has a 5-inch touchscreen that enables easy TCU control by machine operators. The controller is available with the TC130/TC131 series. The TS-5 includes USB data logging, standard ethernet and many communications options. Plus, OPC UA / Euromap 82.1 capabilities are now included as standard in the new TS-5.
