CronoLine IL-E 200/240-15/4

Glanded centrifugal pump with in-line design for pipe installation with built-in frequency converter for electronic control for constant or variable differential pressure (dp-c/dp-v).

Design:

• Single-stage low-pressure centrifugal pump
• Spiral housing in in-line design (suction and pressure ports with the same flanges in one line), flanges PN 16 – drilled acc. to EN 1092-2
• Pressure measuring connections (R 1/8) for mounted differential pressure sensor (version ...-R1 without differential pressure sensor)
• Pump housing and motor flange with cataphoretic coating as standard.
• Mechanical shaft seal for water feed up to T=140 °C; up to Tmax= +40 °C a glycol admixture of 20 to 40% by vol. is permitted.
• Special mechanical shaft seals for water-glycol mixtures deviating from the 20–40% glycol by volume and a fluid temperature of ≤ 40 °C or fluids other than water (additional charge).

Accessories:

• Mounting brackets for fixing to the foundation
• IR-Monitor
• IR-Stick
• IF-Module PLR
• IF-Module LON
• IF-Module Modbus
• IF-Module BACnet
• CAN IF-Module
• Control systems VR-HVAC/CCe-HVAC/SCe-HVAC
• Differential pressure sensor (DDG) sets 0-10 V for pumps in version ...-R1

Standard equipment:

• One-button manual operation level for:
  • Pump On/Off
  • Setpoint and speed adjustment
  • Selecting the control mode: Δp-c (constant differential pressure), Δp-v (variable differential pressure), PID controller, n-constant (control mode)
  • Selection of operating mode in dual pump operation (main/standby operation, parallel operation)
  • Configuration of operating parameters
  • Error acknowledgement
• Pump display for displaying:
  • Control mode
  • Setpoint (e.g. differential pressure or speed)
  • Error and warning messages
  • Actual values (e.g. power consumption, actual value of the sensor)
  • Operating data (e.g. operating hours, energy consumption)
  • Status data (e.g. status of SSM and SBM relay)
  • Device data (e.g. pump name)

Additional functions:

• Interfaces: Control input "Overriding Off", "External pump cycling" (effective only in dual pump operation), analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for control mode (DDC) or for remote setpoint adjustment, analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for actual value signal of the pressure sensor, Infrared interface for wireless communication with the operating and service unit Wilo-IR-Stick/IR-Monitor, plug-in position for Wilo IF-Module for connecting to the building automation, configurable, potential-free fault and operating/ready message, interface for dual pump communication
• Three-phase AC motor with frequency converter
• Integrated dual pump management
• Adjustable time interval for pump cycling (in dual pump mode)
• Integrated full motor protection
• Different operating modes for heating mode (HV) or air-conditioning mode (AC)
• Access disable
• Different operation levels: Standard / Service
