HVAC as well as domestic water systems often need a steady pressure level to function properly. A quality bladder expansion tank installed can help absorb pressure, reduce stress on your system and improve longevity. Professional bladder expansion tank suppliers can provide you with quality tanks designed to last and perform at their best. There are tanks available for nearly any commercial or industrial need.
What Is a Bladder Expansion Tank?
Bladder expansion tank - as you may have guessed by now - is an expansion tank which has a bladder inside that keeps water separate from compressed air. When thermal expansion occurs due to heating in a closed or heated water system, the expansion of water volume caused by the rise in temperature will compress the bladder against the tank's air cushion to relieve system pressure.
Bladder expansion tanks are used in:
HVAC systems
Chilled water systems
Hot water circulating systems
Boiler systems
Industrial water treatment
Constant pressure water system
Cooling tower circulating systems
Bladder expansion tanks can prevent unnecessary pressures, water hammer, pump cycling and damage to pipes/equipment.
Benefits of Using a Bladder Expansion Tank
Consistent System Pressure
Prevents spikes in water pressure when properly sized and installed. Allows for a more balanced system.
Longer Equipment Lifespan
Reduction in pressure spikes help reduce stress on equipment such as pumps, valves, heat exchangers and piping.
Improved Energy Efficiency
Consistent water pressure can allow HVAC systems and circ pumps to run more efficiently.
Less Corrosion
Isolation of water from tank shell allows less contact between the two, reducing corrosion in tank.
Ease of Maintenance
Available bladder replacement options allow for quick and inexpensive maintenance.
How to Choose a Reliable Bladder Expansion Tank Supplier
Safety and reliability should be your top priorities when determining which supplier is right for you.
Industry Experience
Working with a supplier who understands global HVAC and industrial standards ensures you will receive an engineered solution specific to your application.
Product Quality
Options like carbon steel, stainless steel, and heavy duty rubber bladder will improve your tanks reliability and longevity.
Configuration Options
A small HVAC system will not need the same tank capacities or pressure ratings that a large industrial system will. Ensure your supplier offers OEM and custom fabrication options.
Support
Recommendations on product selection, installation support and after- sales service can save you valuable time and money. These are just a few ways a reputable supplier will support you.
Export Experience
Working with an global supplier gives you access to their knowledge of international certifications, packaging requirements and logistics.
