Type DHT Seismic VibrationIsolator
The Type DHT seismic vibration isolator is a medium-load, high-performance spring isolator designed for applications requiring both vibration control and seismic protection. It is ideal for HVAC main units, cooling towers, water pumps, and mechanical equipment installed in seismic-prone zones.
Built with an all-directional restraint structure, the DHT model effectively limits both vertical and lateral movement during operation or seismic events. Its heavy-duty steel frame, corrosion-resistant coating, and spring deflection capacity up to 50 mm make it a reliable solution for long-term equipment stability.
What makes the DHT model suitable for seismic zones?
The DHT isolator is equipped with an integrated lateral and vertical restraint system, which significantly improves the equipment’s stability during earthquakes or vibrations. This ensures both operational safety and structural protection.
🔧 Key Features
Designed for medium-load equipment
Multi-directional seismic restraint ensures safety during earthquakes
High-strength steel housing with powder coating for durability
Stable spring deflection for consistent vibration isolation performance
Top-mounted adjustment bolt for leveling
Available in multiple load capacities and spring colors for easy identification
Can this vibration isolator be used for chillers?
Absolutely. This spring vibration isolator is specially designed for water-cooled screw and centrifugal chillers. Its stainless steel housing resists corrosion, while the rubber and spring combination effectively isolates vibrations from the unit, preventing transmission to cooling pipes and building structures. It meets the requirements of a vibration isolator for chillers.
Does this vibration isolator need to be bolted to the floor?
Installation depends on equipment type and site conditions. For portable or temporary equipment such as mobile compressors or modular generator sets, non-bolted installation is possible due to the isolator’s weight and design stability. For permanent installations, bolting is recommended for added security.
Can the DHT isolator be customized for different loads or deflections?
Yes. We offer customized load ranges and spring deflections based on your equipment requirements. Standard deflection is up to 50 mm, but custom options up to 150 mm are available upon request.
