Tank Mixing System
Frequently Asked Questions:
How does it work?
Answer: The powerful tank mixing system of Pulsair consists in a Large compressed air/gas bubbles are sequentially released under flat round disks called accumulator plates that are located on the tank bottom. The rising bubbles use gravity and physics to mix and blend liquids faster and more efficiently than conventional mixing methods such as mechanical impeller mixers or air spargers.
What size tanks do you mix?
Pulsair has successfully mixed fluids in all type of tanks and vessels from a 5 gallon buckets to multiple 6 million gallon+ storage tanks holding heavy crude oil.
How much does it cost?
Answer: Pulsair tank mixing system are custom engineers and designs our mixing system to meet the unique mixing requirement of each customer and their specific tank geometry. Contact us directly and tell us more about your mixing requirement and we will send you a free quote.
What size tanks do you mix?
Answer: Pulsair can mix and blend liquids in any size tank regardless of its size, geometry or number of tank. This includes and is not limited to 55-gallon drums, IBC totes, rail tank cars, small, medium and large volume tanks up to around 30 million gallons
How much compressed air will your system require?
Answer: The SCFM (standard cubic feet per minute) requirement varies with each custom engineered mixing system. Pulsair mixing system use ~90% less compressed air than an air sparger. While the Pulsair system does not consume a lot of compressed air, it does require a high momentary demand.
What size air compressed do I need?
Answer: This depends on the tank size, number of tanks and mixing requirements. The air compressor horse power is determined after the SCFM requirement is calculated from the quote.
How do I adjust the settings?
Answer: All Pulsair mixing systems are adjustable. The operator can change the speed (pulse rate) and power (air pressure) in order to maximize the mixing efficiency and meet the respective mixing goals.
Can I use nitrogen or CO2 gas?
Answer: Yes, You can switch from compressed air to nitrogen or CO2 gas without any modification to the Pulsair mixing systems.
Can it mix high viscosity liquids?
Answer: Yes, Pulsair has successfully mixed liquids up to 100,000 centipoise (sour cream)
Can it mix liquids with a high percentage of solids?
Answer: Yes, Pulsair has successfully mixing liquids with solids up to ~80% (TiO2 – titanium dioxide slurry)
What is the accumulator plate made out of?
Answer: Depending on the liquid and tank material, the accumulator plates can be designed and manufactured out of a variety of materials including but not limited to carbon steel, 304 SS, 316 SS, PVC and aluminum.
How many accumulator plates do will I need in my tank?
Answer: The number of accumulator plates in the tank will depend on the tank floor diameter or dimension. The type of liquid, viscosity, settling rate and mixing goals are also factored in to determine the number of accumulator plates.
How do I attach or secure the accumulator plates to the tank bottom?
Answer: Anchoring and securing the accumulator plates to the tank bottom depends on the tank material and tank design. We’ve done thousands of mixing projects in a wide variety of tanks and will help you come up with a solution.
Do you have portable mixers?
Answer: Yes, Pulsair has lightweight portable mixing system for 55-drums, IBC totes and mid-size tanks.
What sort of maintenance is involved?
Answer: First, once the system is installed, there is zero in-tank maintenance. Typical maintenance outside the tank includes checking the air filter annually.
Will this type of mixing process cause air entrainment?
Answer: No, the Pulsair mixing process produces large air bubbles that will all reach the liquid surface so there will be no air entrainment.
How many tanks can I mix?
Answer: 40-60 tanks. Pulsair designs multi-tank mixing system that can operate 40-60 tanks from a single touch-screen controller.
Is Pulsair safe to use in hazardous locations?
Answer: Yes, it’s very safe to use. Pulsair offers all-pneumatic mixing systems that operate on compressed air, nitrogen and CO2 gas. Where low voltages are required, the terminals can be housed in explosion proof enclosures or by placing electrical components outside of the hazardous locations.
What is the life expectancy of a Pulsair mixing system?
Answer: Many, many years. There are Pulsair installations from the 1980s still in operations today. There are no moving parts inside the tank. What little maintenance does occur happens outside the tank and usually involves changing or checking an air filter. There are no seals, gear boxes, shafts or other items that commonly break down with mechanical mixers. The only moving parts aside from the air compressor are logic relays and the opening and closing of injection valves.
