Frequently Asked Questions

Answer: Compressed air is released intermittently through a specially designed nozzle called accumulator plates at the tank bottom. The released compressed air will form big bubbles that will push and carry the denser product up.  The lighter product will fill the void by displacement effect and thus creating a vertical mixing action within the tank.

Answer: Pulse Air System has successfully mixed fluids in all type of tanks and vessels from a 200 litre of drum, to 1 cubic metre of IBC tanks, to 26 kilo-litre of ISO tanks and to an approximately 60,000 cubic metre of storage tanks.

Answer: Pulse Air System’s equipment and configuration will be depending on several factors such as tank geometry, tank layout and number of blending tanks. Our representative will design the system uniquely to suit your site condition and your needs. Contact us directly and tell us more about your mixing requirement and we will send you a free quote.

Answer: Pulse Air System 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 200 litre drums, IBC totes tanks, ISO tanks, small, medium and large volume tanks up to around 60,000 cubic metre.

Answer: Yes, Pulsair has lightweight portable mixing system for 55-drums, IBC totes and mid-size tanks.

Answer:  First, once the system is installed, there is zero in-tank maintenance. Typical maintenance outside the tank includes checking the air filter annually.

Answer:  40-60 tanks. Pulsair designs multi-tank mixing system that can operate 40-60 tanks from a single touch-screen controller.

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.

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.

Answer: We have executed numerous numbers of projects for our customers. Many of which are existing customers who come back to us looking for the same system for other tanks in their plant. We also have customer endorsement, one example is Oiltanking in which they have written in their monthly newsletter how pleased they are in the results PulseAir mixing system has provided. So how confident we are in our system? The customer satisfaction has said a lot to this.

Answer:  The compressed air requirement varies with each Pulse Air System design. The compressed air consumption will largely be depended on the blending rate that the client requested on.  Typically, Pulse Air mixing system uses ~90% less compressed air than an air sparger.

Answer: This depends on the tank size, number of tanks and mixing requirements.  The air compressor horse power is determined after the compressed air requirement is calculated.

Answer:  All Pulse Air Mixing Systems technologies 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.

Answer: Yes, You can switch from compressed air to nitrogen or CO2 gas without any modification to the Pulse Air mixing systems.

Answer:  Yes, Pulse Air has successfully mixed liquids up to 12,000 cst (marine additives / concentrates)

Answer: Yes, Pulse Air has successfully keeping solid particles in suspension ~70% of solid (calcium fluoride)

Answer:  Depending on the liquid, tank material and client’s requirement, 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.

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.

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.

Answer: No, the Pulse Air mixing process produces large air bubbles that will all reach the liquid surface so there will be no air entrainment. In fact it helps to minimize tiny bubbles in the product by forcing it to join with the big bubble the system creates.

Answer: In your plant, do you use air compressors for your equipment? We can use the same compressor for our pulse air system. If you do not have it, we can propose a food grade filter that will ensure minimal contamination to your product.

Answer: Does your product oxidize easily? If yes, we can try with your existing air compressor on a sample of your product.
