High pressure plate heat exchanger from thermowave
The high pressures associated with natural refrigerants in cooling systems have long been a talking point in the industry.
German plate heat exchanger manufacturer, thermowave, has a new solution for just such applications, namely the thermolinePlus which is good for cooling applications up to 63 bar. The heat exchanger is small, light and has a low refrigerant charge.
thermowave says the thermolinePlus is ideal for CO2 applications, such as heat recovery in cascades, industrial cooling processes, as well as in heat pumps, because its high pressure resistance.

Looking for a new adiabatic gas cooler for your transcritical CO2 plant?
You're in luck.
Güntner has its new Gas cooler Diagonal Compact (GGDC) on show at Chillventa. The cooler comes with a humidification pad and Güntner Hydro Management (GHM) humidification control.
The company is being bold with its mission for this product. Güntner wants “to push the CO2 equator geographically southwards.” The GGDC has adiabatic air pre-cooling so it can work efficiently with transcritical CO2 plants in parts of the world with ambient temperatures which go above +40 °C.
The GHM control continuously controls the water volume according to the heat exchanger's fan speed as well as the measured ambient temperature and humidity. This way, the wetting water distribution is constantly and ideally adjusted to the operating conditions.

Monitoring the oil concentration in cooling processes
Anyone working with lubrication in compressors for air conditioning systems knows that the oils reduce cooling effectiveness. And, you have to monitor oil content to know the best oil circulation ratio. That depends on factors including the refrigerant in use, the compressor and process conditions. Manual sampling and offline analysis is virtually impossible.
Sounds tough to do, right? Yes, and how do you do it?
SensoTech has a solution, its LiquiSonic OCR analyzer.
With it, you can monitor the oil circulation ratio 'online and directly' using sonic velocity measurement. Install the LiquiSonic in the pipeline and use with a pressure transducer to do the monitoring. The sensor includes two Pt1000 temperature probes which means you can calculate the temperature- and pressure-compensated oil concentration in real time.

New ammonia heat pumps series from GEA
GEA has a new series of ammonia heat pumps for internal installation going into production soon. GEA's RedAstrum heat pump keeps the ammonia in the plant room with the heat distribution through a water circuit. That means the application range of the heat pump is greater.
The RedAstrum is perfect for industrial applications where you need hot water at temperatures between 55 and 80 °C. It is also good for supplying heat into nearby district heating networks. It is small enough to be fitted into plant rooms. It gets its low power usage from the speed controlled screw compressors.
The RedAstrum heat pump appears to have a high COP too.

Take control of your refrigerated cabinets and counters with EVCO
EVCO has interesting line-up of refrigerated cabinet, counters and island controllers at Chillventa this year.
The Italian energy control company is showing its EV3 series 200 temperature regulation controllers, which include a TTL port for MODBUS serial communication. Compact and stylish, they are perfect reducing wasted energy on refrigerated units at normal, static, or fan-driven temperatures.
Also, on show is its single and dual circuit chiller controllers, the so-called 'EV3 CHIL' & 'EVD CHIL',as well as its 'EV3 HP' & 'EVD HP' reversible, single-circuit residential heat pump controllers. The EV3 CHIL and EVD CHIL are ideal for running single circuit air to water and water to water chillers using up to two compressors.

JC to show off York hot water absorption chiller
Johnson Controls is to show off its YHAU-CL single-effect hot water absorption chiller at Chillventa this year.
Its YHAU absorption chillers contain an advanced two-step evaporation and absorption cycle system to divide work between chillers. The YHAU uses two different pressure levels to split the absorption process into two stages. Chilled water flows through the tubes in series via two evaporators. At the same time, the system distributes concentrated lithium-bromide solution absorber shell side in the opposite direction.
This makes refrigerant absorption into the concentrated solution more effective, which reduces the overall pressure, and lowers the solution concentrations. As a result, the chiller is more efficient and reliable than more conventional designs.
