Ascaso Steel UNO PID Black&Wood

Lever coffee machine with 1 circuit, electronic thermostat

TheSTEEL UNO PID Black&Wood coffee machine has one circuit. To use steam, it is therefore necessary to switch the coffee machine to steam and activate the temperature rise. The system must heat up and generate a sufficient amount of steam. To make espresso, it is again necessary to switch and wait for the system to cool down.

Single thermoblock coffee machines have a lower purchase price and use an electric thermostat to achieve a stable temperature. Less positive is the fact that you have to wait for the cooling/venting process. It will delay you for about 1.5 to 2 minutes compared to two circuits. Therefore, this coffee maker is mainly for black coffee and espresso lovers who rarely have a cappuccino.

Coffee machine for home and office use with vibrating pump

Thevibrating pump is the most common type of pump in home, lever and automatic coffee machines. It is a significantly cheaper technology than a professional rotary pump. The optimum pressure for espresso preparation is approximately 9 bar and for vibrating pumps we calibrate to approximately 10-11 bar.

However, vibrating pumps come from the factory with a capacity of approximately 15-20 bar. So how do you get the machine to be set to the desired lower pressure? By using the OPV pressure relief valve that every coffee machine with this type of pump must include. A vibrating pump is noisier than a rotary pump and a coffee machine with a vibrating pump cannot be connected directly to the water supply. However, this is not so necessary for home and office use.
