Logic Unit SRL 6-40
If the level electrode (high or low level limiter) is installed in an isolatable level pot outside the boiler, make sure that the level pot is drained and the connecting lines are rinsed at regular intervals. For this purpose the connecting lines must be shut off and opened at regular intervals and by opening and closing the drain valve the lines and the level pot will be rinsed.

Level electrode NRG 16-50S
The level electrode NRG 16-50 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).

Panel Adaptor Small Rotary Button
The Panel Adaptor Small is designed for use with the small form factor SPECTORmodul controllers with rotary button (e.g. NRR/NRS 2-50, 2-51; LRR/LRS 1-50, 1-51; TRS 5-52; PRS 50) and enables controller installation in a control cabinet door. It offers the advantage of status visibility and alarm testing without opening the cabinets door. The installed adaptor fulfi lls the protection class IP65.

Level electrode NRG 16-36
The level electrode NRG 16-36 is used in conjunction with level switch NRS 1-50 as water level limiter for steam boilers and (pressurized) hot-water installations and in conjunction with level switches NRS 1-52 / NRS 1-54 or NRS 1-2 / NRS 1-5 as water level controller. Water level limiters switch off the heating when the water level falls below the set minimum level (low water).

Limiteur de température de retour Kalorimat BW 31, BW 31A PN 40 / Class 150, DN 15 – 25 PN 25 / Class 150, DN 40
Le limiteur de température de retour régule la consommation en fonction des besoins dans les réseaux de chauffage industriels. Lorsque les températures de fluide chutent, il augmente le flux de fluide dans la conduite de retour. Le fluide ne s’écoule que si sa température est inférieure à la température de fermeture. Ceci permet de maintenir toujours le débit, la pression et la température du fluide à un niveau suffisant et de réduire les pertes de chaleur.

Électrodes de niveau NRG 16-61, NRG 17-61, NRG 19-61, NRG 111-61
Associées à l’appareil de commande URS 60, URS 61, les électrodes de niveau NRG 1x-61 sont utilisées comme sécurité de niveau d'eau élevé pour les installations de chaudière à vapeur et à eau surchauffée. ■ Une sécurité de niveau d'eau élevé empêche le dépassement du niveau d’eau maximal défini (NH) et coupe par ex. l’arrivée d’eau d’alimentation. ■ La visualisation et la commande sont assurés au choix par le biais de l’appareil de commande URB 60 ou le SPECTORcontrol.

SPECTORmodul for land and marine applications
Safety, reliability, availability and economy have always enjoyed top priority in boiler operation. To an increasing extent, another aspect is being added for the plant operators: process automation and visualization. To meet these stringent requirements, GESTRA AG has – for more than five decades now – been working exclusively with electrode systems that are low in maintenance and wear; in contrast to other systems, they function entirely without moving parts, which leads to high service lifetimes and very low failure rates. By now, these GESTRA electrode systems are being applied in many different areas of the energy supply centre.

Level electrodes NRG 16-60, NRG 17-60, NRG 19-60, NRG 111-60
NRG 1x-60 level electrodes are used in conjunction with the URS 60 / URS 61 control unit as water level limiters for pressurised steam and hot-water plants. ■ Water level limiters switch off the heating when the water drops below the set minimum level (LW). ■ Visualisation and operation take place via the URB 60 or SPECTORcontrol operating unit.
