Expobar Office Pulser
Also see:
The Pulser design has been influenced by commercial coffee machines and contains features found on much more expensive prosumer machines such as; insulated boiler, non compression water/steam valves, balljoint mountings for steam/water wands, HX (Heat Exchanger) system etc. It's a value for money machine that performs as well as more expensive HX machines. It is simple to operate and with its large internal cold water tank, you can make plenty of drinks between fill ups and no requirement for plumbing in to the mains water system.
It has a powerful heating element and large 1.5 litre boiler, you can draw espresso shots and use steam at any time, without "preparing" the machine first (and minimal impact on brew temperature). The model pictured is the manual version, with a single switch that starts/stops the shot
