Tracer CH530 Chiller Controller

Revolutionary control of the chiller, chilled water system, and your entire building with unprecedented accuracy, reliability, efficiency, and support for maintenance using the chiller’s PC-based service tool. Chiller reliability is all about producing chilled water and keeping it flowing, even when facing conditions that ordinarily would shut down the chiller — conditions that often happen when you need cooling the most.

Tracer CH530’s Main Processor, DynaView™, is fast and keeps the chiller online whenever possible. Smart sensors collect three rounds of data per second, 55 times the data collection speed of its predecessor. Each device (a sensor) has its own microprocessor that simultaneously converts and accurately calibrates its own readings from analog to digital.

Because all devices are communicating digitally with the DynaView™ main processor, there is no need for the main processor to convert each analog signal one at a time. This distributed logic allows the main processor to focus on responding to changing conditions

—in the load, the machine, its ancillary equipment, or its power supply. Tracer CH530 constantly receives information about key data parameters, temperatures and

current. Every five seconds then a multiple objective algorithm compares each parameter to its programmed limit. The chiller’s Adaptive Control™ capabilities maintain overall system performance by keeping its peak efficiency. Whenever the controller senses a situation that might trigger a protective shutdown, it focuses on bringing the critical parameter back into control. When the parameter is no longer critical, the controller switches its objective back to controlling the chilled water temperature, or to another more critical parameter should it exist.

Variable water flow through the evaporator

Chilled-water systems that vary water flow through chiller evaporators have caught the attention of engineers, contractors, building owners, and operators. Varying the water flow reduces the energy consumed by pumps, while requiring no extra energy for the chiller. This strategy can be a significant source of energy savings, depending on the application. With its faster and more intelligent response to changing

conditions, Tracer CH530 water flow sensing option accommodates variable evaporator water flow and its effect on the chilled water temperature. These improvements keep chilled water flowing at a temperature closer to its setpoint.

User-defined language support

DynaView™ is capable of displaying English text or one of the two alternate languages that are stored in DynaView™ at one time. Switching languages is simply accomplished from a settings menu.

Similarly, TechView™ accommodates a primary and a secondary language from the same list of available languages.
