DJ Type Damping Base
DJ Type Damping Base for Heat Pump — Professional Vibration Isolation and Noise Control Solution
DJ Type Damping Base For Heat Pump
The DJ Type damping base is available in multiple models, with a load-bearing capacity ranging from 50 kg to 1000 kg or more, depending on the specific version. To select the correct model, it is important to consider the total weight of your heat pump unit, the number of mounting points (typically 4 or 6), and whether the load is evenly distributed. Our engineering team can assist with load calculations and suggest the most suitable configuration based on your equipment specifications and installation environment. Overloading or uneven load distribution may affect the damping performance and reduce service life, so professional guidance is strongly recommended for optimal performance.
The DJ Type damping base uses high-damping rubber materials such as natural rubber or NBR (nitrile rubber), selected based on application demands. These materials comply with international standards such as ISO 6446 and DIN 53513, ensuring excellent mechanical properties. The rubber is formulated to resist fatigue, compression set, oil exposure, UV, and ozone degradation, making it suitable for both indoor and outdoor environments. Even after prolonged use under fluctuating temperatures and load cycles, the damping base retains its elasticity and vibration absorption capability, with little to no performance decay over time.
In standard installations on flat and level surfaces, the DJ Type damping base can be placed directly beneath the heat pump unit without the need for extra components. However, for enhanced security or in special cases—such as uneven flooring, seismic zones, or rooftop mounting—optional anti-vibration bolts, anchor plates, or anti-slip brackets are recommended. These can help prevent shifting, slippage, or equipment misalignment during high-speed operation. Installation guidelines are available, and custom mounting kits can be provided upon request to match different project needs.
Yes, it is specifically designed to perform well with high-speed, variable-frequency, and inverter-driven compressors. The rubber compound and base geometry are engineered to dampen not only standard mechanical vibrations but also high-frequency harmonics and micro-vibrations that are common in modern inverter systems. This reduces the likelihood of structural resonance, equipment fatigue, and long-term wear on internal components. As a result, the DJ Type damping base can improve equipment longevity, reduce noise complaints, and maintain operating efficiency in dynamic environments.
The DJ Type damping base is designed to be maintenance-free under normal operating conditions. It contains no moving parts and does not require lubrication, tightening, or recalibration. In typical HVAC or mechanical system use, the damping base can last between 5 to 10 years or longer, depending on factors such as installation quality, frequency of operation, environmental exposure (UV, moisture), and heat pump size. Periodic visual inspection is recommended to check for surface wear, deformation, or aging cracks in the rubber—especially in harsh outdoor or industrial environments. If signs of deterioration appear, replacement is advised to ensure continued vibration protection.
DJ Type Damping Base Usage Cases Summary
Vibration Reduction for Commercial Building Heat Pumps
A large office building experienced significant vibration and noise from multiple heat pump units, negatively impacting the office environment. After installing DJ Type damping bases, vibrations were effectively isolated, reducing noise levels by approximately 30%. This significantly improved workplace comfort, decreased equipment failure rates, and extended the heat pumps’ service life.Vibration Control for Industrial Plant Chilled Water Units
High-speed operation of large heat pumps in a factory caused ground-transmitted vibrations that affected sensitive precision instruments nearby. By using DJ Type damping bases as machine supports, mechanical shocks were absorbed effectively, reducing vibration transmission through the floor. This ensured a stable working environment and improved production efficiency.Stabilizing Rooftop Heat Pump Systems
Rooftop heat pumps on a high-rise residential building were subject to wind forces and mechanical vibrations, causing instability and increased noise levels. Installation of DJ Type damping bases combined with anti-slip fixtures significantly enhanced equipment stability and reduced vibration noise, meeting residents’ demands for a quiet and comfortable living environment.High-Frequency Vibration Control for Variable Frequency Heat Pumps
Variable frequency heat pumps at a hospital generated high-frequency vibrations during startup and speed adjustments, which caused structural fatigue. The DJ Type damping base, made with specially designed rubber materials, efficiently absorbed these high-frequency resonance waves, reducing vibration amplitudes, ensuring smoother operation, and lowering maintenance costs.Vibration Reduction for Commercial Supermarket Cold Chain Heat Pumps
Vibrations from heat pump equipment in a large supermarket’s cold chain system transmitted through the floor, negatively affecting customer experience. Installing DJ Type damping bases under the heat pump feet effectively reduced vibration and noise spread, enhancing shopping comfort and ensuring safe and stable equipment operation.
