UK: Daikin Applied is the first to offer a chiller with R32 refrigerant with the launch of its new EWAT-B series.
The new generation of air-cooled scroll chillers will be available for cooling only and heat recovery applications from 80kW up to 700kW cooling capacity at nominal conditions.
Compared to the previous R410A range, seasonal energy efficiency ratio (SEER) is said to be improved by 10%.
Thanks to its lower flammability A2L classification, Daikin says that R32 can be safely used in many applications including chilled water systems.
The new Daikin Applied chiller series will be available with two efficiency versions (Silver and Gold), combinable with three sound configurations (Standard, Low and Reduced) and providing full customisation on project-specific requirements.
An extensive list of options and accessories are offered, such as the fully integrated hydronic kit for fixed flow or variable flow operation and partial or total heat recovery for sanitary hot water production.
The new series is fully compatible with the Daikin On Site cloud-based platform, which offers a number of advanced functionalities including remote monitoring, system optimisation and preventive maintenance. It also offers master/slave functionality as standard, allowing the management of up to four units on the same system without the need for external control devices.
For more complex installations, Daikin Applied offers the Intelligent Chiller Manager, allowing energy optimisation of the system and, when necessary, full customisation of the control solutions to the specific installation’s needs.
Daikin was the world’s first company to introduce split air conditioners using the lower GWP R32 refrigerant in 2012. It has since expanded the range to include commercial air conditioners and heat pumps. As of December 2017, Daikin had sold approximately 12 million R32 units in more than 50 countries.
