Rüster water leak & condensation prevention

The Rüster Liquid pressure sensors are designed and manufactured with high accuracy and long term stability in mind. With our expierance in industrial applications for measurment of liquids or gases we decided to use the same high quality materials in our HVAC Liquid pressure program. 

Rüster condensation prevention

When cooling systems are used in a building condensation of piping, cooling ceilings/fancoils etc is always  a possibility. Condensation can cause a lot of damage. Thats why it is very important to monitor the "room"conditions and monitoring the temperature in the piping. But even than condensation can take place in some aereas. 

Especially for this siuations Rüster has developed RWDCP condensation prevention controller.

The RWDCP is designed to meet the requirements for a low cost device to provide early warning of condensation conditions.

The sensor provides either a volt-free contact or current output and is housed in a small easy to install enclosure. The sensor has a adjustable setpoint and LED indication of status.

Rüster water detection

The damage to a building or equipment inside when piping or even rain water is leaking into the building can be substantial. When a event lik this is happening it is imprtant to detect this problem as soon as possible to prevent unnes-sesary damage.

Just for these cases Rüster building controls profides a wide range of water leak detection equipment.

RWDM series of controllers

The RWDM series of waterleak alarm controllers is designed for use with the RWDP pointsensor, RWDC detection cable and the RWDR Rain sensor.

The modules have a LED indication of the water leak status and a sounder that can be enabled or disabled. The relay output can be used in manual and auto reset, and can be used as an alarm signal for connection to a BMS controller or remote alarm annunciation panal.

The cable excitation used is an isolated AC signal witch ensures the detector cable will not be subject to oxidation or erosion over time. Avoiding the degradetion problems associated with DC systems.

RWDP water detection point sensor

The RWDP water detection point sensor is designed to detect water leak at localised points. Standard the sensor is provided with 2 m connection cable.

The sensor must be used in combination with the RWDM series water leak detection controllers and not be directly connected to a BMS system

RWDC water detection cable

The RWDC water detection cable sensor is designed to detect water leak at larger areas as server rooms, technical rooms etc. Standard the sensor is provided with 3 m connection cable.

The sensor must be used in combination with the RWDM series water leak detection controllers and not be directly connected to a BMS system
