Gestra NRG16-11S

BRAND : Gestra

Description

The level electrode NRG 16-11 S is used in conjunction with level switch NRS 1-50 (de-energizing delay: 15 seconds) as water-level limiter for steam boilers and (pressurized) hot-water installations on board of seagoing vessels, mobile offshore platforms or river boats. Water level limiters switch off the heating when the water level falls below the set minimum level (low water).
