Emerson
Emerson is introducing a new range of standard and digital scroll compressors for medium temperature refrigeration applications designed for low GWP refrigerants classified as A2L. The F-Gas regulation requires manufacturers to make their refrigeration systems future-proof to reduce direct and indirect CO2 emissions which contribute to global warming: this involves choosing the most suitable refrigerant and system architecture. To support the transition towards regulatory compliance, Emerson has developed solutions for a variety of refrigerants such as CO2 (R744), Propane (R290) or alternatives like HFO blends / A2L refrigerants. Each solution is optimized for the specific refrigerant. The new YB and YBD compressor range was optimized internally and externally for F-Gas compliant low GWP A2L refrigerants – such as R455A, R454A, R454C and R1234yf, to create the most reliable compressor for refrigerants with a higher HFO content. The architecture, main system design and installation with HFO blends are similar to those with HFC refrigerants. These similarities will make refrigeration installations simpler to install, commission and maintain. This compressor range is suited for commercial food retail and food service applications.

Resource Data Management (RDM) is excited to be launching a new Bluetooth solution for the HVACR building controls industry.
Using Bluetooth Low Energy (BLE) technology, the modules transmit data between heating, ventilation, air conditioning and refrigeration (HVACR), lighting and other building control devices. Ideally suited for space-restricted areas or if building structure hinders the installation of cable solutions. Operating on a Mesh topology, a major benefit compared to systems communicating point to point, the mesh system allows signals to hop between available modules, bypassing obstacles and creating a more robust and reliable networking solution. The new Bluetooth range includes two input/output modules, a communication module for RDM R232 controllers and a temperature probe. It also includes two access points for RDM’s control and monitoring system head-end DMTouch.
