Technical data
Bodywork
All stainless steel (AISI 304).
Brewing head
Commercial brewing head. Weight 4.05 kg (9 lb).
Pre-infusion
Dual pre-infusion system: mechanical pre-infusion system with
progressively working piston and static pre-infusion chamber.
This reflects a smooth coffee extraction with optimum aroma,
body and “crema”.
Dual boiler
system
Rocket R 58 machines come with one dedicated boiler for coffee
water and one boiler for steam and hot water (service boiler). The
guarantee of consistent performances.
Boilers
Coffee water boiler: 0.58 litre capacity. Copper made. External
insulation.
Service boiler: 1.7 litre capacity. Copper made. Boiler comes
with lead free brass end plates and additional external insulation
for optimum thermal retention.
Optimised boiler capacity ratio to heater power. Results in fast
heat up time.
Heaters
Coffee water boiler: 1.400 W
Service boiler: 1.400 W
Max. simultaneous power consumption: 1.550 W
Pump
Full commercial rotary type pump (not vibration type pump) with
external pressure adjustment.
Temperature
control of
boilers
Electronic control by PID sensors inside the boilers for precise
temperature control. True boiler temperature displayed on PID.
Not a “calculated” group temperature display which does not
accurately reflect the “true” group temperature.
Pressure
gauges
One dedicated gauge for pump pressure and one for service boiler
pressure control.
Stainless steel
steam wand
With our cool-touch technology: anti-burn (only the nozzle gets
hot); easy cleaning as milk doesn’t bake on wand; more efficient
steam, as heat is not dissipated around the wand. Steam nozzle
designed for easy milk foaming with fine texture.
Electronically
controlled
Microprocessor controlled automatic level control of coffee water
boiler, service boiler and fresh water reservoir, with low water
level indication system.
Safety valve
Fully certified commercially rated safety valve.
Water supply
2.5 litre fresh water reservoir or alternatively by turning the
control switch, steel braided direct water connection (hard
plumbed) with full drip tray drainage system.
