Overview

Quick and easy installation due to the pre-assembled system. This minimizes troubleshooting.
Energy saving: operation in the partial load range according to the current demand.
Reliable system thanks to coordinated components.
Compact design, easy access to all components.
All from a single source. Less information to explain at the time of purchase.

Type
High efficiency, automatic, ready-to-connect installation with multiple pumps for the realization of large flow rates in heating, air-conditioning and refrigeration systems. Three to four electronically regulated dry-running, parallel-connected VeroLine-IP-E or CronoLine-IL-E series dry-running linear pumps. Of these, one pump is redundant. Including Smart SCe controller.

Application
Pumping heating water (according to VDI 2035), glycol water, cooling water and chilled water without abrasives in heating, air conditioning and refrigeration applications.

Equipment/function

3 to 4 pumps per VeroLine-IP-E or CronoLine-IL-E series unit, of which 2 or 3 pumps are in operation and 1 serves as a back-up pump
Standard IE2 electric motor
Automatic pump control system with Smart Controller SCe
No corrosion of parts in contact with water
Galvanized steel base frame with height-adjustable anti-vibration mounts that isolate structure-borne sound
Corrosion protected steel distributor
Flange PN 16 acc. to EN 1092-2 on discharge and suction side for connection to pipe system
Pre-mounted seals on discharge and suction side
Shut-off valves on suction and pressure side
Pressure-side non-return valve
Differential pressure sensor
Pressure gauge on discharge and suction side
