Delta Flush Controller
Giving you back control of your own flushing regimes.
Delta flush controller is designed to give the control back to you for your control of legionella and other forms of waterborne pathogen.
There are many different approaches to controlling the proliferation of bacteria in water and different solutions are needed in different settings.
The Delta flush controller will allow you to monitor different aspects of your water and has been designed to work on one of three pilars.
Anti Stagnation
Monitoring of the water flow over time.
You define what the time period monitoring is over and what the minimum flow required in that period is.
If flow over that period is below the threshold flushing will commence until that minimum flow volume is achieved.
Every Delta Flush controller has Data Logging built in as standard.
The data logging can be handled one of two ways, either through the onboard date logger or through a BMS connection.
Firstly the data logging can be achieved via the onboard data logger which writes directly to the removable SD card located at the top of the face of the controller.
This will create your flushing record identifying how much flow was seen over the flushing period and over how many tap events this occurred. What volume of water was flushed if any and for what reasons flushing occurred be it for temperature range or for stagnation. If flushing occurred due to a water outside of temperature the flush on temperature is logged and the flush off temperature is also logged.
All these events are time and date stamped for your legionella records.
This is produced in a .txt format which is converted via our free to download excel template into an excel record which you can easily convert to a PDF and save.
BMS data logging is via a ModBus connection and the tables can be found in the O&M Manual or can be advised upon request.
Temperature Control
Monitoring of the system temperature to ensure it stays within agreed ranges.
You define the set points for the on and the off conditions as well as any safety override timers you may want to include.
Once temperature either rises or falls into the activation zone depending if monitoring for hot or cold water the system will flush until the off set point is detected.
This is designed to reduce bacterial proliferation by avoiding danger zone temperatures.
Additional safety features such as run on timers and alarms are available as standard.
Data Logging
Stagnation and Temperature
Combining both approaches the Delta Flush Controller will monitor both for temperature and for stagnation.
As with either of the other pillars the thresholds are entirely yours to set. Your Delta Flush Controller will come to you pre programmed with your agreed parameters.
By monitoring both flow volume and temperature the Stagnation and Temperature pillar offers the maximum control in reducing bacterial proliferation and managing the risks of legionella and other waterborne pathogens.
