Safe, sensorless drive monitoring With the speed and frequency monitor UH 6937 from the SAFEMASTER S Series, DOLD offers an efficient, economic solution for safe, sensorless drive monitoring. Monitoring the output frequency of traction converters is just one of the many different ways to use this component. In case of over- or underfrequency, violation of the set window range or wrong direction of rotation the frequency monitor shuts off safely, proving its benefit over frequency converters with integrated safety functions in any application where simplicity, flexibility, and safety are required. As an additional protective measure, the device can be adapted to an application by pressing just a few buttons. With the appropriate wiring, the device can offer the safety functions STO (safe torque off), SOS (safe operation stop), SLS (safely limited speed), SSM (safe speed monitoring), SSR (safe speed range) and SDI (safe direction) in accordance with EN 61800-5-2. With the help of ergonomically shaped buttons on the front, and a lit LCD display, you can quickly and easily access parameters relevant for the application, such as monitoring functions, delay times, and frequency ranges for up to four operating modes – all without a PC.

More than just drive monitoring Regardless of whether the set-up operation must be monitored safely, protection via speed limitation is needed or a safety gate is released after detection of standstill - the speed and standstill monitor UH 5947 of the SAFEMASTER S series is the right choice for your application. The device can be operated via the 4 buttons on the front and the LCD display, thus enabling simple parameterisation. For example, the encoder type, speed limits per operating mode and delay times can be flexibly adapted to your application. During operation, the current speed values can be read directly at any time, which in particular makes commissioning easier. To prevent manipulation, the configuration can be protected against unintentional changes by means of a parameter lock after commissioning. For multiple use, the configuration can easily be transferred from unit to unit via interface. The device status or the current speed can further be processed by a control system via a semiconductor signal output. The speed and standstill monitor UH 5947 covers the combined application of encoder signals and PNP or NPN sensors. Alternatively, NAMUR sensor technology can be used as a device variant. The device can be used in temperature ranges from -20 to +60 degrees Celsius and up to heights of 4000 metres.

The spiral tube heat exchanger essentially consists of a jacket and a spiral tube bundle. The finned tubes are built into a spiral in the jacket, which creates a long thermal path. Spiral finned tubes produce high levels of turbulence that help reduce contamination. The bundle tubes can expand optimally. Flow rate: 1-300m3 / h Operating pressure: 16-40 bar Connections: 11/4 “-DN 150 Recommended max. Temperature difference: 150 ° C Materials: 1.4401 / titanium benefits High performance: Spirally finned tubes compactly installed, give the heat exchanger a large exchange surface with a high thermal output. Compact and light design, large number of different models and equipment for different applications. applications Different applications: Applicable for a wide range of different pressure, flow and temperature conditions. Ideal for steam and hot water, district heating, swimming pool Stock Up to DN 100 material in stock

That is the new ZAcube fan system – with just a few movements, you can effortlessly and immediately install a highly efficient fan configuration in various arrays and sizes, exactly as needed. Up to five levels, they can be stacked atop one another or side by side. With the use of simple connecting equipment, effortless manual mounting to the modules using standard screws is possible. Using an ingenious click system we have ensured rapid, simple accessibility to the ZAcube's internal mechanism. The ZAcube conforms to current dimensions for standard filters. It is cost-effective and fits into planning optimally.

ST series safety sensors are suitable for the monitoring of protective devices on machines without inertia and allow the system in which they are used to reach a safety category up to SIL 3, PL e and Category 4. These sensors use RFID technology and provide high protection against any manipulation thanks to a unique code transmitted by the actuator. Since they have no mechanical elements, they guarantee a long service life even in applications with frequent operating cycles and under harsh environmental conditions. Their protection degree is rated IP67 and IP69K and they mantain the maximum safety level PL e, even when connecting up to 32 sensors in series. It is possible to choose among 3 kinds of actuators with different fixing and actuating directions. This means that the sensors can be installed on all types of machines and guards, both large and small.
