Wilo DL-E 100/145-11/2-S1

Wilo DL-E 100/145-11/2-S1 Dry-Running Double Pump

Dry-running double pump in inline design for installation in pipelines or on a foundation, featuring an integrated frequency converter for electronic control, including constant or variable differential pressure control (Δp-c/Δp-v).

Design
Electronically controlled dry-running double pump in inline construction with flange connection and automatic power adjustment.

Application
Pumping of heating water (as per VDI 2035), chilled water, and water-glycol mixtures without abrasive particles in heating, chilled water, and cooling systems.

Features/Functions
Operating modes:

- Δp-c for constant differential pressure
- Δp-v for variable differential pressure
- PID control
- Setpoint operation (n=constant)

Manual operation interface:
- Setting the differential pressure setpoint
- Setting speed (manual mode)
- Selecting operating mode
- Pump ON/OFF selection
- Configuration of all operating parameters
- Error acknowledgement

External control functions:
- Control input "Priority Off"
- Control input "External pump changeover" (only effective in double pump operation)
- Analog input 0-10 V, 0–20 mA for setpoint operation (DDC) and remote setpoint adjustment
- Analog input 2–10 V, 4–20 mA for setpoint operation (DDC) and remote setpoint adjustment
- Analog input 0–10 V for actual value signal of pressure sensor
- Analog input 2–10 V, 0-20 mA, 4–20 mA for actual value signal of pressure sensor

Indication and display functions:
- Collective fault signal (SSM)
- Collective operation signal (SBM)

Data communication:
- Infrared interface for wireless data exchange with IR monitor/IR stick
- Slot for Wilo IF modules (Modbus, BACnet, CAN, PLR, LON) for integration in building automation systems

Protective functions:
- Full motor protection with integrated tripping electronics
- Access lock
- Double pump management (double pump or 2x single pump)
- Duty/standby operation (automatic changeover in case of failure)
- Duty/standby pump changeover after 24 hours
- Parallel operation
- Parallel operation with efficiency-optimized peak load activation/deactivation

Your benefits:
- Energy savings thanks to integrated electronic power adjustment
- Simple operation via Green Button Technology and display
- Various operating modes: Duty/standby and parallel operation
- Configurable fault response tailored to heating and air-conditioning applications
- Integrated full motor protection (KLF) with tripping electronics
