Pfannenberg’s Signaling Solutions Provide Efficient, Safer Environment for Overhead Cranes

Modern Industrial Audible and Visual Signaling devices that preserve lives and prevent injuries are vital for critical Industrial Safety!

The Challenge…

One of the largest independent rail car repair shop networks in North America wanted to create a safer environment for their employees. They needed a way to alert workers to the presence of their 25-Ton overhead cranes as they moved near their work area. They approached their material handling partner to help them create a safer environment.

The Solution…

Having had experience with Pfannenberg signaling products the material handling company presented the customer with a  PATROL PA 10 and a PYRA PY X-M-10 to go on each of their two overhead cranes. The recommendation for two devices is to offer a visual and audible warning as the cranes are in motion.

To ensure the best solution, our PATROL PA 10 audible alarm was chosen because it offers the ability to produce 80 different alarm tones with 4 stages. A unique tone was chosen for each crane so the workers can distinguish one from the other without being distracted from their work.  This creates not only a safer environment, but also a more efficient one.

After the horns and strobes were installed, their customer offered the following:

“We currently have two 25 Ton bridge Cranes at our facility, it is a very loud and has low visibility. Our workers were having a hard time seeing the cranes move and also could not hear them either. Pfannenberg’s lights and sounders were recommende to be installed on our cranes as an audio/visual warning system so our workers would be aware of the crane movement. This system has accomplished this task.” – Rail Repair Shop

Pfannenberg is proud to increase Industrial Safety with its robust, field-proven, visual and audible signaling devices for alarm, warning, and indication.

Drinktec 2017: Pfannenberg to exhibit for the first time

Pfannenberg, the specialist for industrial thermal management solutions and signaling technology will be exhibiting for the first time at Drinktec, the world’s leading trade fair for the beverage and liquid food industry to be held in Munich from 11 to 15 September 2017.

Pfannenberg will be at stand 138 in Hall B3 showing tough, efficient thermal management solutions and signaling technology for the beverage and liquid food industry.

Visitors will be able to see the latest signaling technology and thermal management solutions for the food and beverage industry at stand 138 in Hall B3. Exhibits will include cooling units with corrosion resistant stainless-steel covers and robust signaling devices with high IP classifications. These products are designed for the toughest environments and are therefore suitable for use where liquids are processed and in production systems which require frequent cleaning.

A demo stainless-steel cabinet demonstrating these features will show a NEMA cooling unit, an air/water heat exchanger including a water jet test, a DTT top-mount cooling unit, a stainless steel rainhood and filterfans in stainless steel design.

“Food production places great demands on manufacturing technology. Our efficient, reliable and tough cooling and signaling technology guarantees maximum machine availability in the fast-cycling and highly dynamic processes in the food and beverage industry, starting with raw material processing through manufacture and quality control to packaging,” explains Annarita Amadei, Industry Group Manager Food and Beverage at Pfannenberg.

IoT-enabled packaged solution
The communication-enabled cooling units in the εCool X series that will be exhibited are ideal for companies wanting to make their production fit for Industry 4.0 and at the same time improve machine availability. These thermal management solutions for electrical enclosures can be integrated directly in the user’s automation systems. If required, they can also provide relevant device parameters via the Cloud for remote maintenance. Users benefit from customized maintenance, cost-efficient service and better machine availability thanks to preventative maintenance.

Reliable cooling
Modern production systems such as filling lines are usually permanently in operation. The cooling units and filterfans from Pfannenberg are fitted with IP 56 housing and corrosion-proof stainless-steel covers which makes them the optimum solution for the economical cooling of electrical enclosure technology.

Exhibits at Drinktec will include the new compact 6301C cooling units from the εCool 6000 series. Their power, and their compact design in particular, make them suitable for use in a wide range of applications.

Despite their space-saving design they offer the same energy efficiency, service friendliness and cut-out compatibility as the standard models: they cut energy consumption compared to traditional cooling devices by up to 43%, with a further 10% reduction in standby operation.

Tailor-made process cooling
In particularly sensitive areas of food and drink manufacture, the maintenance-free air to water heat exchangers and the EB series industrial chillers allow economic system solutions which work independently of the ambient air. Typical areas of application are filling lines and packaging systems. Pfannenberg chillers – with cooling capacities from 3.2 to 148.8 kW – cool sophisticated electronic systems. Both standard ready to-use units and fully customized ones can be provided.

This will be demonstrated at Drinktec with the EB 95 WT. Starting from the compactly designed, highly efficient and easy to service standard unit, this chiller can be equipped with several additional features to match specific applications.

For example, all devices can be equipped with a hydraulic bypass, a SMP55 controller with error messages panel and a ASI communication module enables the unit to be integrated the in the customer’s system. The EB devices are UL certified and can be used at ambient temperatures from -20 °C to +45 °C. All chillers in the range allow users to benefit from lower energy and operating costs, space-saving installation, high reliability and long machine life.

Robust signaling technology
Signaling-2.jpgWith high levels of ambient noise, the manufacture of beverages and liquid food makes serious demands on signaling technology. The status of packaging, laser inscription or filling machines and lines must be permanently displayed so that response times can be optimized and costly downtime minimized. Warning lights and acoustic alarms must signal hazards, risks or technical faults immediately, even in the vicinity of noisy conveyors operating at full capacity. Against this background, combinations of visual and audible signaling devices are the best choice.

Signaling technology suitable for operation in production environments such as these will be exhibited:

  • The BR 50 stacklights: This device is of a modular construction and uses sound and flashing, blinking or solid lights to signal statuses and dangerous situations reliably
  • The QUADRO and LED-HI multi function lights
  • the PYRA sounder/flashing light combinations
  • the PATROL and DS sounders

All of which are suitable for use in the demanding conditions of the drink and liquid food industry, will also be exhibited.

Pfannenberg Quadro-LED-Hi : New Multifunctional Light for Industrial Applications

The NEW Quadro-LED-Hi visual alarm device is used to notify of hazardous situations and to indicate the status or fill level of machines and systems. Possible application areas include the operation of industrial machines and systems, building safety and controlling traffic on factory premises. The optical signals of the lights are created with LEDs delivering a high level of luminous efficiency.
Thanks to robust mechanical construction and categorization in high protection classes (IP 66, IP 67 and IK08), the Quadro-LED-Hi is suitable for indoor and outdoor use. Modular in design and multi-functional, these visual alarms are cost-effective, versatile and powerful signaling solutions.
“The Quadro-LED-Hi has everything an industrial light needs: not only a high light intensity but also wide coverage area thanks to its well-thought-out design. Furthermore, it is extremely robust. Neither aggressive environmental conditions nor driving rain, or condensation can effect its performance. With many functions and combination options, industrial companies can cover a wide range of applications with one flexible lighting solution which can be adapted to their requirements,” says Carsten Hippler, Signaling Product Sales Manager at Pfannenberg.
Powerful signaling

The luminosity of the Quadro-LED-Hi can be adjusted up to 75 cd. However, luminosity is not a sufficient measure of the effectiveness of a signaling device.

The actual coverage area under real environmental conditions is much more decisive and this has been shown for the first time with Pfannenberg’s 3D Coverage Approach. This takes account of factors such as the type of alert and the positioning of the device.

This method indicates that, used with a clear cover, the signaling coverage of the Quadro-LED-Hi is as follows (width/height/depth):

  • Information applications – 49.5 m x 47.5 m x 36 m
  • Warning applications – 22 m x 21 m x 16 m
  • Alerting applications 11 m x 10.5 m x 8 m

Versatile in use

Users can adjust the operating modes of the LED light at any time within a flexible range of options: continuous blinking frequencies at 1 Hz /2 Hz and flashing frequencies at 0.1Hz / 0.5 Hz / 0.75 Hz / 1 Hz /2 Hz. The Quadro-LED-Hi is even more versatile used with a multi-voltage power pack. There is a 24 V variant with a functional range of 11 V to 60 V (DC) and a 230 V variant with a functional range of 90 V to 253 V (AC) at 50/60 Hz. The lights are also equipped with an inrush current limiter. The Quadro-LED-Hi is designed for ambient temperatures ranging from –40 °F to +130 °F.

Pfannenberg Signaling Alarms Notify Personnel and Community of Chlorine Gas Leak

Chlorine Gas Detection Alarm System Works as Designed

In 2015 Pfannenberg provided signaling notification appliances (alarm horns and strobes) to the North Tonawanda Wastewater Treatment Facility as part of their new Gas Detection Alarm System. On the evening of Tuesday, September 13, 2016 there was a very small chlorine gas leak. Pfannenberg’s PATROL Signaling Alarms were triggered through the system notifying plant personnel and surrounding area. The alarms could heard up to a mile away from the facility.

>> All clear given following chlorine leak (VIDEO)

Even though the leak was very minor, everyone was pleased to know that the system worked as specified, providing adequate warning. Hopefully there will never be a larger leak, but if there were then it is reassuring to know that the personnel and community will have plenty of advanced warning to the potential hazard.
