• Aluminum heat exchanger with excellent thermal stability for coffee extraction. • Power absorption of only 450W with working thermostat of 98 °C. • Inlet/outlet 3-way solenoid valve • Vertical group closure to give at the machine more steadiness at group closure. • Patented Compensator, located in the lower part of the group which allows an effortless closure at constant pressure over time. • No water leaks from the filter: that means no dirt deposits on bottom side (problem that persists in traditional systems). • No group adjustment the compensator at each use adapts itself to the gasket squashing that occurs everytime. with consequent savings on spare parts. • Uniform extraction of the coffee due to the stabilization of the working pressure. • Easy access to group for maintenance purpose through the top cover, which is fixed by means of only two screws. • CARATTERISTICHE TECNICHE / TECHNICAL DATA Pompa Ulka EP4FM / Ulkopump EP4FM Serbatoio acqua / Water tank Dimensions / Dimensions: Assorbimento: / Power absorption: Scambiatore: / Exchanger: Termostato di lavoro: / Working thermostat: Termostato di sicurezza: / Safety thermostat: versione tanka interna / internal tank versxxi 20 bar 2 litri / 2 liters 150/330/290 450 watt / 450 watts alluminio / aluminum 98°C 145°C
