Carrier
Carrier has introduced the AquaForce Vision 30KAV with PUREtec refrigerant, a new line of high-performance, compact process cooling chillers with ultra-low global warming potential (GWP) refrigerant R-1234ze. The new chiller line is optimised for industrial processing such as food manufacturing,
pharmaceuticals, chemicals, plastics, metal industries and applications requiring ultra-reliable cooling up to -12°C. Carrier’s AquaForce Vision 30KAV air-cooled, variable-speed
screw chillers are designed to minimise energy consumption and impact on the environment while maximising performance and ease of installation and maintenance. Energy efficient solutions like the AquaForce 30KAV chiller support Carrier’s 2030 Environmental, Social and Governance (ESG) Goals to reduce its customers’ carbon footprint by more than one gigaton.
The chiller is available in four sizes, spanning capacities
from 280 kW to 800 kW into -4°C/-8°C medium temperature process cooling and from 530 kW to 1300 kW into 12/7°C high- temperature process cooling or comfort cooling. The unit’s carbon footprint is minimised due to its combination of ultra-low GWP HFO refrigerant, a 40% reduction in refrigerant charge due to use of Novation micro-channel heat exchangers and outstanding energy efficiency delivered by the onboard variable speed drive, which precisely matches compressor speed to load. The chiller’s compact design, with a physical footprint one-third less than standard 30KAV chillers, enables it to be deployed where space is tight without compromising performance.
For mission critical applications, such as process cooling and food manufacturing, Carrier has developed an ultra- fast capacity recovery option. In the event of the chiller power supply being interrupted, the recovery option enables immediate chiller restart following power restoration with 100% capacity recovery within one minute, minimising the risk of damage to the process or products being cooled.

Condair
Condair is launching the Condair DC-N, a condensing
dehumidifier with an external condenser unit that can dry an area without the risk of overheating. Traditional condensing dehumidifiers introduce heat to a room from their built-in condensers when they dry the air. The Condair DC-N’s external condenser allows the heat generated during drying to be remotely exhausted, similar to a split air conditioner. This makes it much easier to manage the temperature of a room that is being dehumidified.
Dave Marshall-George, sales director at Condair commented: “Condensing dehumidifiers dry the air by creating a cold surface upon which moisture in the air condenses and drips to drain. This process generates heat, so the dry air leaving the dehumidifier can be several degrees warmer than the humid air entering it. For some projects, this added heat can cause an issue. When it is, ventilation is frequently used to control temperature. However, by introducing fresh air to control temperature, moisture can enter the room, making the humidity control less effective. “The Condair DC-N is the ideal solution in these
circumstances. When the room is cold and below the required temperature, the dehumidifier’s on-board condenser introduces heat as well as drying the air. Then when the room’s temperature set point is reached, the remote condenser activates, ejecting the heat externally rather than into the room. This allows a room to remain sealed, therefore providing efficient drying, whilst achieving the ideal internal temperature and humidity.” The Condair DC-N range offers drying capacities from 263 to 940 litres per day (@30°C/80%RH). It incorporates energy efficient EC fans, high quality components and R410A refrigerant gas. Operation is controlled via an on-board digital display, an optional remotely located controller (up to 50m away) or via BMS using Modbus.
