AW290

The AW290 is a high-performance, high temperature air source heat pump designed to meet heating, cooling, and domestic hot water demands in commercial applications, including apartment buildings, hotels, and schools. The AW290 utilises natural R290 refrigerant for exceptional energy efficiency and a reduced environmental impact.

The AW290 is available in two output options – 35kW and 50kW. Up to 16 units can be arranged in cascade to provide capacity up to 800kW, making them ideal for commercial installations.

EVI powered

The AW290 units are equipped with EVI technology, enabling high energy efficiency and stable performance. With inverter and EVI technology, the series reaches A+++ energy level and COP is up to 4.4.

R290 refrigerant

The units use R290 refrigerant, a natural and environmentally friendly alternative with a low global warming potential. R290 has been widely adopted in modern heat pump technology due to its excellent thermodynamic properties, delivering high efficiency and reliable performance in air-to-water heat pump applications.

R290 leak sensor

The integrated R290 leak sensor ensures safe operation with high sensitivity and a rapid 5-second response time. Designed for long-term reliability, it requires no calibration or maintenance and has an impressive 15-year lifespan, providing continuous protection and peace of mind.

Refrigerant/water sensor

The AW290 heat pump includes an automatic refrigerant/water separator, ensuring safe operation by preventing any gas from escaping into indoor spaces. This built-in safety feature helps maintain system efficiency and protects occupants from potential exposure.
