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

Wilo DL-E 100/145-11/2-S1 Dry-running Twin Pump

Dry-running twin pump in inline design for pipeline installation or foundation mounting, featuring an integrated frequency converter for electronic control of constant or variable differential pressure (Δp-c/Δp-v), among others.

Design
Electronically controlled dry-running twin pump in inline configuration with flange connection and automatic performance adjustment.

Application
Circulation of heating water (according to VDI 2035), cold water, and water-glycol mixtures free from abrasive substances in heating, cooling, and air conditioning systems.

Features/Functionality

Operating Modes
- Δp-c for constant differential pressure
- Δp-v for variable differential pressure
- PID control
- Manual control (n=constant)

Manual Operation Interface
- Adjustment of target differential pressure
- Speed setting (manual mode)
- Selection of operating mode
- Pump ON/OFF switch
- Full configuration of operating parameters
- Resetting faults

External Control Functions
- Control input "Priority OFF"
- Control input "External Pump Changeover" (effective only in twin pump operation)
- Analog input 0–10 V, 0–20 mA for manual control operation (DDC) and remote setpoint adjustment
- Analog input 2–10 V, 4–20 mA for manual control operation (DDC) and remote setpoint adjustment
- Analog input 0–10 V for actual value signal from pressure sensor
- Analog input 2–10 V, 0–20 mA, 4–20 mA for actual value signal from pressure sensor

Signal and Display Functions
- Collective fault message (SSM)
- Collective operating message (SBM)

Data Exchange
- Infrared interface for wireless data transfer with IR monitor/IR stick
- Slot for Wilo IF modules (Modbus, BACnet, CAN, PLR, LON) for integration into building management systems

Safety Functions
- Full motor protection with integrated tripping electronics
- Access lock
- Twin pump management (twin-pump operation or 2 x single pump)
- Duty/standby operation (automatic fault switch-over)
- Duty/standby operation with pump changeover every 24 hours
- Parallel operation
- Parallel operation (efficiency-optimized peak-load connection and disconnection)

Your Advantages
- Energy savings due to integrated electronic performance adjustment
- User-friendly with green-button technology and display
- Multiple operating modes: duty/standby and parallel operation
- Configurable fault behavior tailored to heating and air-conditioning applications
- Integrated full motor protection (KLF) with trip electronics
