Chiller with variable-speed compressor operates between 10 and 100 percent of its rated capacity. The design applies variable-speed green compressor technology from the HVAC industry to produce energy savings over hot-gas-bypass regulation.

Steam generated from boilers is used in many industrial processes, including manufacturing, refining, chemical processing and power generation.

With Nexus technology, in addition to a chiller’s refrigeration system, a secondary microchannel heat exchanger system is added.

When it comes to industrial process heating and cooling systems, a number of plants are running with systems that rely on a fixed-speed centrifugal pump to circulate the medium and a control valve to throttle the flow to a required rate.

Model DTI-1098 is used to cure rolls of cross-linked thermoplastics for a foam rubber manufacturer.

Siemens Drive Technologies Division is providing variable-frequency drives (VFDs) for a $450 million cellulosic ethanol plant under construction by a U.S. subsidiary of Abengoa, a developer of renewable energy solutions based in Seville, Spain.

How to avoid bearing current failure and insulation failure when designing and installing variable-frequency drive systems is the focus of “VFD Application Guidelines” a technical bulletin from Colmac Coil, Colville, Wash.
