OF THE MAIN COMPONENTS
- Accelerator pump with high-efficiency ECM technology. - Single or dual primary for safe operation (with automatic switching). There are two configuration levels: Simple configuration (user/operator mode). - timer, - daytime and night-time DHW temperature setpoints, - daily or weekly programming. Advanced configuration (administrator mode): - anti-legionella treatment: setpoint, duration, day etc., - the high/low safety and alarms thresholds, - assignment of relays for information feedback, - PID regulation, - override operation (pump, opening 3-way valves etc.).
- ITEX range, PWB4+ or PWB 7+ model, ACS-certified, - Stainless steel 316L plates and NBR Plug-in© gaskets. - Ready to be installed and connected. - 230V- 1Ph-50 Hz + Earth supply, - High/low safety temperature and control sensor (automatic or manual reset), - Motorised primary 3-way valve with or without reset to zero, - Rated safety valve on cold water, - Electronic control featuring a simple, user-friendly menu: intuitive navigation thanks to the rotary selector on the front, - 2 contacts for information feedback (operation and faults), - ModBus/RTU type RS 485 2-wire communication protocol, dialogue via CMS possible, - Display of data and potential faults, - Log of last 20 faults, - Accelerator pump operation counter, - Adjustable factory configuration.
HEE primary accelerator pump
Electrics and control box:
- Valve actuator with no-current reset to zero (safety device in instantaneous production).
Supplied fitted. Depending on the water quality, there are two technologies to choose from: - A glandless cast iron accelerator pump body: the motor rotor is cooled by the driven fluid. As a result, however, this technology may not be best suited to a certain type of water prone to forming scale. - A glanded stainless steel accelerator pump body: the motor is not in contact with the driven fluid. This technology is suited to aggressive fluids and therefore compatible with a broad range of water qualities.
Single or dual DHW circulator (operation with DHW storage tank)
Only available in the glanded stainless steel accelerator pump body version for optimum reliability. The customer is responsible for electric and hydraulic connection and the control.
Loop accelerator pump (supplied unconnected)
Heat exchanger insulating material
- Thermoformed insulation composed of 2 pre-cut half-casings. Light and resistant, it can be installed or removed without special tools. Limits losses by insulating the exchanger and its sealing strip completely.
