Special features/product
benefits
- Energy efficiency class A
- Highest degrees of efficiency
due to ECM technology
- Up to 80% electricity savings
compared to uncontrolled circulation pumps
- Front operation and access to
the terminal space, variable installation positions, display
independent of position
- Simple installation due to
combination flanges PN 6/PN 10 (with DN 32 to DN 65)
- Can be used in
cooling/air-conditioning systems without ambient temperature
limits
- Pump housing with cataphoretic
coating for the prevention of corrosion by condensation
formation
- System expansion by means of
retrofittable interface modules for communication: Modbus,
BACnet, CAN, LON, PLR etc.
- Remote control via infrared
interface (IR-Module/IR-Monitor)
Technical data
- Permissible temperature range
--10°C to +110°C
- Mains connection 1~230 V,
3~230 V, 50/60 Hz
- Protection class IP 44
- Screwed connection or flange
connection (depending on type) Rp 1 to DN 100
- Max. operating pressure,
standard version: 6/10 bar or 6 bar (special version: 10 bar
or 16 bar)
Equipment/function
Operating modes

fault-actuated switchover/time-dependent pump cycling):
Various combinations with Stratos IF-Modules (accessories)
possible
- Parallel operation
(efficiency-optimised peak load activation and deactivation):
Various combinations with Stratos IF-Modules (accessories)
possible
