FIRE PROTECTION ACTUATORS FROM GRUNER

The benchmark for reliability in fire protection and smoke protection.

RELIABLE WITH TOP TECHNOLOGY

100% GERMAN QUALITY

Our premium actuators are designed for extreme conditions and they extend across a wide range of torque ratings. All the main components are made of steel which means that they can withstand temperatures of more than 120 °C over an extended period of time.

CLOSED IN AN INSTANT The unique modular design and the comprehensive range of accessories enable bespoke OEM actuators to be created for each and every requirement. All actuators can be activated using the building management system. The system can be linked up via Modbus RTU or BACnet MS/TP to assure reliable operation of central monitoring and the reporting of legally defined inspection cycles in the event of a fire.

ALWAYS PREPARED FOR EMERGENCIES

MAXIMUM SAFETY

Our actuators for fire protection systems deliver a wide range of convincing benefits:
>   manual adjustment without a power supply;
>   spring preload for continuous torque right across the entire 95° angle of rotation
>   compliance with CE in accordance with EMC directive 2004/108/EC and low-voltage directive 2006/95/EC;
>   outstanding economy achieved through energy-saving by holding each unit in its limit position.

Additional options: positions reported by potential-free additional switches, temperature fuse protection for mounting in conduits and a great deal more.

PRECISION CONTROL OF AIR FLOWS: VAV SOLUTIONS FROM GRUNER

Regardless of whether you need accurate metering for the control of airflows in residential properties, for comfort at the workplace or for process air, you are defining challenging requirements for the actuators you need to do the job. Would you like to learn right now about our portfolio of appropriate actuators? Here you will find details of our complete product range:

PERFECTLY COMPLEMENTING OUR STANDARD PRODUCT RANGE

THE NEW VAV GENERATION

The actuators made by Gruner optimise VAV solutions through exceptionally precise metering and rapid response times. This assures uniform distribution of air combined with a constant and high level of cooling power. Intelligent links involving multiple variables such as static and dynamic differential pressure are the key to draught-free cooling through controlled and constant volumetric flow rates.

CONSUMPTION AND DURABILITY

ROBUST, ENERGY-SAVING ACTUATORS FOR INCOMING AND OUTGOING AIR FLOWS

When selecting the right actuator systems for HVAC equipment, finding the correct performance rating is not the only factor. Durability and energy efficiency are also key decision-making aspects in the planning of an actuator.

Here at Gruner, we are therefore committed to the best possible scalability of all parameters in our actuator models. Our benchmarks are low energy requirements, ease of installation and set-up as well as great durability extending over many years of problem-free operation. Consult our portfolio or speak to us to learn about how we go about accomplishing these benchmarks!

CONVINCING PERFORMANCE

TORQUES OF UP TO 60 NM

Moving flap sizes with diameters measuring up to 10 square metres requires vast amounts of power - and Gruner actuators have no problem delivering precisely that. We build performance capability into our actuators up to torque ratings of 60 Nm. This meets all the normal requirements for VAC systems.

EFFICIENCY

LOW POWER NEEDS AT REST AND IN OPERATION

We really abhor the notion of wasting energy. We are therefore always striving to design our actuators to use the absolute minimum of energy while in operation and while at rest. This means you can be sure that our actuators will fit into your energy-efficient concept. To learn more, please consult our product data, or please feel free to get in touch with us.

RELIABILITY

DESIGNED FOR A LONG SERVICE LIFE

For applications such as ventilation, heating and air- conditioning, our minimum specification for the service lives of our actuators comprises 100,000 full movement cycles or 1.5 million partial cycles - they can even achieve a little more than this, even under arduous conditions. For you, this means that you really can depend upon Gruner actuators in your systems for a very long time indeed.

HANDLING

SIMPLE INSTALLATION INCLUDED

We ensure simple installation with a sensible and easy-to- understand layout of all connections, well thought-out operation for entry into service and also with precautions against incorrect operation. This saves your team time during installation, also saving you money. Learn more from the data relating to your desired product, or in dialogue with ourselves.

SUPER-FAST RUNNING ACTUATORS

SAFETY AND FAST PROTECTION

Gruner super-fast running actuators deliver operational reliability, even under arduous conditions. They are able quickly and reliably to open and close safety-related components in laboratories, clean rooms, ultra-clean rooms and fume hoods.

ALSO WITH FAIL-SAFE

ENERGY-EFFICIENT SUPER-FAST RUNNING ACTUATORS

The Gruner 328CS or 328QS super-fast running actuators with a safety position adapt instantaneously to changes in conditions. For applications that also involve positioning during interruptions in the power supply, a specialist type 328QS with fail-safe can be supplied.

IDEAL FOR EXTRACTOR FANS

SAFETY AND RELIABLE COMMUNICATION IN CRITICAL SITUATIONS

Whenever it gets critical, the actuator needs to respond quickly and safely. For this, short closing times are essential. However, even if the power supply gets interrupted, the system remains able to close and open components reliably.

FASTER THAN FAST

5 SECONDS AND LESS

The Gruner family of super-fast running actuators provides you with actuators that can operate for short periods of 5 seconds or even less. With the optional serial interface, very precise positioning is possible.

ACTUATORS FOR BALL VALVES: WE ALSO KNOW ALL ABOUT LIQUIDS.

We know what we’re doing when it comes to the metering of flows with accurate repeatability and precise metering: that is also true of liquids. Our rotary drives for opening, closing or controlling ball valves complement our portfolio of actuators perfectly. Learn about the possibilities that we can create for you when it comes to entirely bespoke solutions for the control of flow rates, using robustly designed actuators that respond perfectly.
