Detail
VIRA SK 2000 is an on-off level control and alarm system for steam boilers. The system combines the SK 2400 panel-mounted controller with the SD 2400 conductivity-type level probe to provide automatic feedwater pump control and reliable boiler water level monitoring.
Automatic On-Off Feedwater Pump Control
The SK 2000 controls the feedwater pump according to boiler water level conditions. The pump is operated automatically to support stable boiler water level management in steam boiler applications.
Configurable High and Low Level Alarms
The system provides configurable high and low water level alarm functions. This supports clear indication of critical boiler water level conditions and helps operators take the required action.
Conductivity-Type Level Detection
The SD 2400 conductivity-type probe is used to detect water level conditions in conductive boiler water. It provides the level information required for automatic pump control and alarm functions.
LED Indication and Panel-Mounted Control
The SK 2400 controller is designed exclusively for panel mounting and features LED indicators for clear local status and alarm indication.
220VAC Supply and Robust Construction
The system operates with a 220VAC supply. It features a non-flammable polycarbonate enclosure and PN 40 pressure class for applicable steam boiler installations.
