EWAT-B chiller

EWAT-B

First air cooled chiller with environmental-friendly R-32 refrigerant

Daikin, world’s first company introducing a new generation of air cooled scroll chiller series with refrigerant R-32.

Daikin, world’s first company introducing a new generation of air cooled scroll chiller series with refrigerant R-32.

Daikin is continuously leading in chiller technology, striving again for innovation with the new generation of air cooled chillers with R-32 refrigerant, expanding it’s Bluevolution range to larger capacities.

Why has Daikin introduced R-32 models?

The global warming potential of R-32 refrigerant is 675, which is only one third compared to commonly used refrigerant R-410. Thanks to the lower flammability classification (R-32 refrigerant falls into category class A2L in ISO817), it can be safely used in many applications including chilled water systems. As a single component refrigerant, R-32 is also easier to recycle and reuse another environmental plus in its favour.
