Less vibration, less noise
Isotope products increase comfort around HVAC systems
Chillventa is the leading trade fair for refrigeration, air conditioning, ventilation and heat pumps. Getzner will also be represented with its own stand in Nuremberg from 8 to 10 October and will be shedding light on these key topics from the perspective of vibration insulation and noise protection. The Isotop® machine mounts combine the advantages of the proprietary polyurethane (PUR) elastomers Sylomer®, Sylodyn® and Sylodamp® with those of steel springs and metal elements. Compared to rubber products, they show their strengths particularly in the operation of HVAC systems, as PUR becomes softer under dynamic loads and better insulates and reduces vibrations and noise. In addition, the material does not become brittle even under difficult environmental conditions and retains its elastic properties in the long term.
Isotop® DZE 3D - reliably absorbs forces from all spatial directions
The latest member of the Isotop® family is the Isotop® DZE 3D. ‘What is unique about this product is that it can absorb accelerations from all spatial directions,’ explains Dominik Riedel, Technical Director of Getzner Spring Solutions. ‘This makes it suitable not only for use in or on means of transport, but generally in geographical regions with earthquake resistance requirements. High wind loads are also not a problem.’ A well thought-out chamber principle with optimally matched PUR materials is the basis for the performance of the Isotop® DZE 3D. ‘A large deflection of the threaded rod is possible. If the horizontal load decreases, the Isotop® DZE 3D returns to its original position. These properties were confirmed in tests in accordance with ICC ES AC156 (2020) at an independent testing institute,’ emphasises project manager Rico Link.
EquipCalc: Proven online selection programme for Isotop®
The basis for optimum vibration isolation is the customised design of the required elastic mounts for the individual application. EquipCalc provides registered users with an online selection programme that determines the optimum solution after entering the weight and number of bearing points. ‘EquipCalc Moduleplanner can also be used to model the composition of HVAC systems with multiple elements. As a result, the user receives suitable products for vibration protection as well as the relevant characteristic values of the overall system,’ explains Rico Link.
Vibration isolation for quieter appliances
Optimally designed vibration protection prevents annoying humming and efficiently reduces the primary airborne noise of appliances. This can be proven by current measurements. ‘We will take the opportunity to present the special features of vibration isolation for HVAC equipment in a specialist lecture at Chillventa. In addition to the physical basics, application examples will be used to show how devices or individual components such as compressors can be optimally elastically mounted and what influence a customised design has on the overall effect,’ announces Simon Waldner.
