BWT bestbarista ROC COFFEE ist eine neue Stufe der Wasseroptimierung für Kaffee und Heißgetränke.
Das System entfernt in der ersten Stufe fast alle Mineralien und unerwünschten Stoffe durch Umkehrosmose.
Anschließend werden gezielt Mineralien, vor allem Magnesium und Silikat, hinzugefügt, um den Extraktionsprozess zu optimieren und eine gleichbleibend hochwertige Wasserqualität zu gewährleisten.
Hier finden Sie die zentralen Unterlagen zur BWT bestbarista ROC COFFEE – speziell entwickelt für höchste Ansprüche bei der Kaffee- und Heißgetränkezubereitung.
Laden Sie sich ganz einfach das technische Datenblatt sowie die Einbauanleitung (EBA) herunter und erhalten Sie alle relevanten Details zur Planung, Installation und Anwendung des Systems.

Application Conditions: Device Fuse
Our ROC systems use a T1.25A fuse. If the fuse blows repeatedly, the issue may be:
Application Conditions: Membrane Capacity
Application Conditions: Water Hardness
We recommend pretreatment of feed water:
“If total hardness exceeds 10 °dH or if the ratio of temporary to total hardness is more than 80%, pretreatment is necessary to ensure product reliability and performance.” This statement is included in section 2.2 of the ROC EBA (Operating Conditions) and applies to all RO products.
Note: This is a recommendation – the membrane can technically handle harder water but may require more frequent replacement.
Certification
Our ROC systems have been developed and tested according to:
Harmonized standards:
A valid EU Declaration of Conformity and CB Certificate are available.
Does a pressure tank provide redundancy?
Yes. For hotels, large kitchens, or big restaurants, we offer:
This creates a fully automated, high-pressure purified water system - ideal for industrial-level demand.
How are the filters tested?
How does a pressure tank work?
A pressure tank contains:
As water fills the tank:
Think of it as a spring-loaded water reserve, ensuring instant availability.
Integrated Non-Return Valve?
What if multiple appliances need water at the same time?
A single RO system may feed:
A pressure tank:
What should I do if the membrane has an organic smell after being inactive for a longer period?
An organic smell can occur after prolonged downtime. This usually disappears after a few minutes of flushing. As mentioned in section 6.3 of the EBA:
"If the system has been out of operation and disconnected from power for an extended period (e.g., during vacation), a 10-minute flush is required before reuse. Make sure the rinse water can drain freely. The flushed water should be discarded."
Are any preservation chemicals, such as sodium thiosulfate, used in the membranes?
A few years ago, membranes were commonly preserved wet in a 1% sodium thiosulfate solution to maintain performance and prevent microbial contamination.
Today, most suppliers – including us – deliver membranes in a dry state, which is easier to handle and ensures a longer shelf life. Preservation only applies to new membranes. Once a membrane has been used, preservation chemicals cannot be re-applied.
Can a pressure tank help during peak demand times?
Yes. In HORECA settings, short peak windows may require 50–100 liters in 30 minutes. A standalone RO system cannot deliver this immediately.
A pressure tank with 200–500 liters capacity ensures sufficient reserve during high-demand periods.
Does a pressure tank provide redundancy?
Yes. In case of:
…the pressure tank maintains temporary business continuity. It ensures critical functions can continue without interruption for a short period.
Why is a pressure tank needed after an RO system?
RO systems filter water slowly, molecule by molecule.
For example, BWT bestaqua ROC systems produce around 2.0 to 3.0 liters per minute. Without a buffer (i.e. a tank), the system cannot meet sudden spikes in demand - like during a busy restaurant service.
How does a pressure tank reduce wear and tear on the RO system?
Without a pressure tank:
A pressure tank absorbs small demands, reducing stress and extending component life.
What is the recommended storage and shelf life of the membrane cartridge?
Are there any regulations regarding RO system disinfection?
Don’t RO systems provide pressure on their own?
No. RO systems output purified water at low pressure, typically just slightly above atmospheric pressure. However, many appliances (e.g. espresso machines, combi ovens, ice makers) require a minimum inlet pressure, often between 1.5 and 3 bar.
A pressure tank stores RO water under compressed air, delivering it with immediate usable pressure.
How are ROCs tested before shipping?
Our ROC products undergo a complete End-of-Line functional test. Each individual unit is connected to a testing station and fully tested.
Production at BWT Dynamics is certified according to ISO 9001.
Warnings on ROC Systems: "No Water" Message
This message may appear when the pump pressure drops below 6 bar. Possible causes include:
