Vibration isolation systems of the Halcyonics Vario series consist of active vibration isolation elements and external controllers exactly matched for these elements. The compact dimensions and versatile application options of this product series make it ideal for OEM installation in customer-specific applications and for configuration of active vibration isolation work areas and platforms in the lab. There are virtually no limits when it comes to the range of uses offered by Vario systems.

Vario Systems are available with different isolation element lengths of 45, 60 and 90 cm (17, 23 and 35 inches). Vario elements are always used in pairs; each matched pair must be operated in parallel alignment with respect to one another. Combinations with 2, 4, 6 or more elements are available on request. Each element has a maximum load capacity of 180 kg. Vario systems can thus handle up to 360 kg.

Active vibration isolation systems from Halcyonics are securely attached from the top to the supporting structure using adapter plates and screw fasteners. Acceleration sensors built into the elements detect vibration transmitted from the floor or generated by an application. By a force feedback control loop and electrodynamic actuators, these systems produce defined acceleration that causes vibration to be isolated.

The isolation effect of the Vario elements starts right at 1 Hz and, above 10 Hz, attains more than 35 dB. A major advantage of Halcyonics active systems is that they eliminate interfering natural low-frequency resonance that is generated by passive systems. The latter systems have a more or less marked natural resonance, typically in the range from 1 to 4 Hz. These passive systems cannot suppress vibration in this frequency range, rather they typically increase it. Compared with passive systems, Halcyonics active systems deliver excellent vibration isolation characteristics right at exceptionally low frequencies of 2-3 Hz. They actively isolate vibration for all the 6 existing degrees of freedom.

Installation of a Vario system is exceptionally easy; the elements of the equipment for the application are attached by screw fasteners and connected to the controller. The latter requires only an AC power output; no compressed air or other media are necessary. Automatic load adjustment settings and other functions are simply selected on the Vario controller using the convenient operating menu.

After installation and selection of the settings, the Vario system does not require any further operator attendance or maintenance and can remain in the continuous operating state indefinitely.
