As the big brother of the safety switch PSENmech, the safe mechanical safety gate system PSENmech with guard locking offers an economical solution for safe monitoring of movable guards. The safety gate is securely locked until the hazardous machine movement has stopped. An unintended restart of the hazardous movement is prevented as long as the gate is open.

Combine the mechanical safety gate system PSENmech with the safety bolt PSENbolt and the result is a complete solution comprising mechanical bolt, handle and safety gate switch.

The safety bolt is available in several versions. You can choose between standard versions and versions with a key. The latter enable the bolt to be locked in a certain position, thus preventing an unintended restart of the machine, during maintenance for example.

Application options of the mechanical safety gate system

Thanks to integrated guard locking, the secure safety gate system PSENmech is suitable for personal and process protection and can be used in numerous industries and applications.

Particularly if you are looking for an economical basic solution for safety gate monitoring, then the mechanical safety gate system PSENmech is right for your application. PSENmech with guard locking can be expanded with an escape release or emergency release.

DCS Siemens SIRIUS Controls Ensures Cold Beer 1 400

Breweries are known for transforming malt, hops, and yeast into beer in gleaming brewing kettles and large fermentation tanks linked by numerous pipes.

Over the centuries, the equipment for mashing, lautering, boiling, and fermenting beer according to carefully guarded recipes has been steadily perfected.


The chiller is the heart of the brewery

One of the most important parts of the brewery, and perhaps the least visible, is the chiller. The fermentation temperature of the beer is crucial, which means that the heat generated by the yeast fermentation must be carefully controlled by the chiller.

If the beer ferments at too high a temperature, the yeast can produce a variety of undesirable aromas that ruin the beer.

According to Justin Thomas, President of G&D Chillers, based in Oregon

"The chiller is the heart of the brewery. Owners invest not only a lot of money in the brewery and brewing equipment, but also a great deal of time in the production of beer. But if the chiller fails, all that goes out the window."

Partnerships to keep pace with growth

Thomas says that growth at G&D Chillers has been exponential over the past 15 years. To continue this rate of success, the company had to look for new ways to meet customer demands for reliable, state-of-the-art chiller options.

For example, G&D Chillers recently teamed up with Siemens and the global distribution and supply chain solutions company WESCO to meet these needs and stay ahead of the competition. "We're still a small manufacturing company, but big enough to produce some technically advanced equipment," says Thomas. "We've always been service-oriented and always stood by our equipment, no matter what the problem. We get the same kind of support and service from Siemens that we give to our own customers."
