Coolzy: 55 cm high x 29 cm x 39 cm, 15.4 kg, easy to carry.
Old Style Portable: typically 80 cm high x 40 cm x 45 cm, 32 kg, hard to move.
In moderately hot weather, a Coolzy can be used on its own (as shown) or with a normal mosquito net. We recommend the optional Igloo bed tent in really hot conditions with indoor temperatures consistently over 28°C at night. The tent amplifies cooling over the bed and can also reduce energy consumption by about 30-40% which is ideal for battery and off-grid applications.
Old style portables are unsuitable for bedrooms. They are much noisier and have relatively low cooling performance compared with a split AC using the same power. Also humidity builds up in room with time.
Coolzy: use it anywhere because there is no pipe
Old-style Portable: has to be close to a window to attach the large exhaust pipe with the window kit
Coolzy: $549-699 plus $15-$30 monthly electricity cost, total cost over three years $1,089-$1,799
Old-style Portable: $350-$990 plus $120-$250 monthly electricity cost (Sydney), total cost over three years $4,670-$9,990
Coolzy: 800-1,100 Watts cooling, 340 Watts electricity (same as a few incandescent light bulbs), 0.25 tonnes CO2 over three years, equivalent to 110 litres of petrol
Old-style Portable: 3,000-7,500 Watts cooling, 1,000-2,400 Watts electricity, 1-2 tonnes CO2 over three years, equivalent to 450-900 litres of petrol.
Coolzy: all cooling directed around people using it
Old-style Portable: mixes air in room, sucks out more air than it cools and sucks in hot air from the roof space outside. Very little room cooling.Click here for more details
Coolzy: 47-54 dB – quiet, like an electric fan
Old-style Portable: 55-63 dB – noisy, can be hard to hear people speak
Old-style Portable: Closed
A Coolzy eliminates the need for an exhaust hose: such a wonderful improvement. It is on caster wheels and can easily be moved where you want to use it. At 15.4 Kg it is easily carried too. Take it anywhere you need cooling, even outside in sheltered places.
The old-style portable comes with a hose and window kit which is fiddly to install, and only works with some windows. That means you cannot easily move it once you have installed it. Plus the exhaust hose is ugly, helps to heat the room, and makes lots of noise.
