According to the data sheet, the 45-litre tank lasts for around 5.5 hours of operation. It is suitable for sales rooms, small workshops or well-ventilated offices.
Y15: the mid-range model
According to the product page, the Y15 cools areas of 100 to 150 m². It weighs 44 kg, measures 92 × 58 × 151 cm and runs at 65 dB. This makes it suitable for hospitality, events and larger offices. You will find all further data on the Y15 product page.
Y20 and Y30: for halls and large areas
The Y20 and Y30 are both designed for 150 to 250 m² and each has a power rating of 1.1 kW. The difference lies mainly in tank and weight: the Y20 offers 300 litres of water at 84 kg, the Y30 130 litres at 50 kg. For the Y30, the data sheet gives around €1.65 in electricity costs for ten operating hours at full load. According to the manufacturer, both models use up to 90% less electricity than air conditioners. More on this in the electricity cost comparison.
How to choose the right model
- Area and room height: Use the area figures as a guide. An appliance that is clearly too small will cool too little.
- Air exchange: Evaporative cooling works best in ventilated rooms, see Evaporative air coolers and humidity.
- Mobility: If you move the appliance often, weight matters.
- Water: A larger tank means less frequent refilling, but more weight.
