Backflow preventers protect water supply
Honeywell BA295 valves protect drinking water systems against back pressure, back flow and back siphonage, ensuring compliance with relevant water regulations.
Pressure reduction valve provides protection
The Honeywell D06 pressure reduction valve is ideal for protecting water installations from excessive supply pressures up to 25bar.
Yet both types are equally easy to install and can be set up in 30 seconds using their Start-Up Wizard.
Modbus is built-in, and there are plug-in cards for other common open and proprietary buses.
Choosing the right Honeywell drive for any application is simple.
The user just selects the motor power and protection class: IP21 or IP54.
All Honeywell HVAC drives are preconfigured, and have a Class C RFI filter.
This versatility means a few model options cater for all HVAC applications up to 30kW.
This greatly simplifies model selection and reduces stockholding.
Plug-in fieldbus cards are available for Profibus, Lonworks, DeviceNet, CANopen, BACnet, Metasys N2, Modbus/TCP, RS-485 and some proprietary buses.
The drives feature a space-saving "bookshelf" design, for panel or surface mounting.
The drives are packed with reliability and energy-saving features, such as over-temperature, power ride-through, trip-less output switching, auto restart and flux optimisation.
Motor control features include flying start, automatic torque boost function, auto identification of motor internal variables for motor reliability, a high switching frequency to reduce motor noise and temperature control to stop the fan when not needed.
The drives also feature inbuilt PID controllers, and pump and fan cascade control to share the load equally between several parallel pumps, extending their lifetimes.
