Lowers energy cost by reducing refrigerant flow restrictions in HVAC filter /driers
What is it?
The SonicWave is an electronic device that conducts sonic and ultrasonic waves into the filter / drier used on HVAC systems. This reduces the RFD refrigerant flow resistance and the energy required to move the refrigerant through the refrigeration circuit.
How does it work?
The SonicWave generates pulsed sonic & ultrasonic waves which interact to loosen and remove sludge from the filter screens. This reduces restrictions in the cells of the screens reducing the energy needed to keep the refrigerant flowing. The WaveClean reduces the energy consumption by an average of 16.5% in HVAC systems by reducing the back pressure in the liquid line filter / drier.
The SonicWave is not designed to eliminate the need for changing a failed filter. The WaveClean cannot be used to clear moisture saturated and tar clogged defective filters. If the filter was opened to atmosphere and exposed to excessive moisture or has excessive carbon in the refrigerant, the filter must be replaced.
Typical Filter / Dryer
SonicWave reduces particle and oil fouling and allows the refrigerant to flow without disturbing the desiccant or allowing foreign materials to circulate in the refrigerant past the filter / drier
Models: 1 and 2
SonicWave reduces particle and oil fouling and allows the refrigerant to flow without disturbing the desiccant or allowing foreign materials to circulate in the refrigerant past the filter / drier.
SonicWave consists of 2 x models
Has a single transducer for use in systems with a single refrigerant circuit
Has dual circuit transducers for systems with 2 compressors / refrigeration circuits
(For systems that have 4 compressors / refrigerant circuits require 2 of the WaveClean2 models)
Introduction to the SonicWave
The Refrigerant Filter Drier (RFD) is an essential protection device for all the other components built into air conditioners and/or heat pumps. See the diagram below for the location of the RFD in a typical refrigeration system:
RFD Filtration Function:
The function of the liquid line filter drier is filtration of small particles, debris along with the suspension of trace moisture. Filtration is usually done with a screen, wire mesh, and the desiccant core itself (see Figure 2). As small particles accumulate on the screen, wire mesh, or desiccant, they can act as very fine filters that remove even finer particles. However, as these fine particles accumulate over time, they can create enough of a pressure drop to cause the liquid refrigerant passing through to flash to a vapour. This can cause a local cold spot on the filter drier and even cause condensation (sweating) to occur on the outer surface of the filter drier’s body. The sight glass also will “bubble” from the refrigerant flashing to a vapour. In this case, a bubbling sight glass is indicating flashing refrigerant. Do not mistake this with a bubbling sight glass associated with an undercharge of refrigerant. There are many times when a filter drier may be partially plugged and technicians cannot feel a temperature difference across it with their hands. Because of this, many filter drier restrictions go unchecked by technicians because they are difficult to sense by touch and feel. A sight glass on the liquid line before the TXV helps alert technicians if any liquid flashing is occurring before the TXV. This flashing could be from loss of sub-cooling or too much static and/or friction pressure drop in the liquid line before it reaches the TXV
RFD Replacement Criteria
Normal RFD Environment
Most Refrigeration Units operate for many years without ever being exposed to either of these conditions. But, the RFD will have some restriction in the screens after only a year or two of refrigerant circulation through the RFD. The oil from the compressor and the particles or residue left in the system after it was installed are captured by the screen cells in the filters. This normal operational process causes the filter screens to become restrictive to refrigerant flow. This does not prevent the unit from operating normally, but it does significantly reduce the energy efficiency of the unit. The compressor must provide more electrical power to pump the same amount of refrigerant through a restricted RFD.
The SonicWave - Introduction
Any restriction in refrigerant flow that was not intentionally designed into the refrigerant circuit will reduce the efficiency of the refrigeration system. Undesirable Restrictions reduce the EER and increase the KW / Tonne ratings for the machine. Undesirable restrictions elevate the energy cost to operate a refrigeration system. The purpose of the SonicWave is to maintain the EER high and the KW / Tonne low at all times by minimising the restriction to refrigerant flow in the RFD. The SonicWave will reduce the energy cost to operate a refrigeration system.
The primary purpose of the SonicWave is to keep the RFD filter screens open to refrigerant flow. It loosens and shifts debris from the individual cells in the screens that are inside the filter. This is the debris that was left in the unit when it was manufactured, installed, charged, and now placed into operation.
Since every refrigerant filter dryer experiences cell restrictions due to residue that was built into the system - then every refrigerant filter dryer is a candidate for the SonicWave.
*NOTICE: “The SonicWave is not designed to eliminate a failed condition in a filter, and cannot repair a defective filter. If the filter was exposed to excessive moisture or to excessive carbon in the refrigerant, the filter must be replaced.”
The SonicWave – Testing
The SonicWave was developed and tested for reducing refrigerant filter dryer restrictions in refrigeration systems owned and operated by the US Federal Government. Packaged Units, Roof Top Units (RTU’s) and Split Units have all been tested under the stringent guidelines of the Federal Procurement Regulatory System and in accordance with IPMVP Guidelines.
The graph in figure 2 illustrates the effectiveness of the Exciter in reducing RFD restrictions and describes the delta T improvement of the refrigerant flow through the RTD. As the Exciter operates over a period of time, the screen cells open up more and more. This opening of the cells consistently reduces the KW / Tonne of the refrigeration system.
Measuring the temperature across the refrigerant filter is the most expedient way to determine the level of restriction of the screens in the RFD. Any Delta T across the filter greater than 3 °F is undesirable. Figure 2 (above) shows the RFD had a daily average delta T exceeding 6 °F. Approximately 10 days after installing and activating the SonicWave, the filter Delta T had dropped to less than 3 °F.
The KW / Tonne averaged 2.752 KW/Tonne on July 19th st and dropped to 2.302 KW / Tonne by July 31st. (2.752 KW / Tonne – 2.302 KW / Tonne) / (2.752 KW / Tonne) x 100% = 16.35% Reduction in electrical energy required to move the same amount of heat for this facility.

Advice about your legal rights is available from your local Citizens' Advice Bureau or Trading Standards office. 11.4 If we fail to comply with these Terms and Conditions, we are responsible for loss or damage you suffer that is a foreseeable result of our breach of these Terms and Conditions or our negligence. Loss or damage is foreseeable if it is an obvious consequence of our breach or if it was contemplated by you and us at the time we entered into this contract. 11.5 We only supply the Goods for domestic and private use. You agree not to use the Goods for any commercial, business or resale purposes, and we have no liability to you for any loss of profit, loss of business, business interruption, or loss of business opportunity. 11.6 We do not in any way exclude or limit our liability for: (a) death or personal injury caused by our negligence (b) fraud or fraudulent misrepresentations. Returns and Refunds This Clause 12 does not affect your legal rights, and further advice can be obtained from the Citizens Advice Bureau or Trading Standards office. 12.1 You have a legal right to cancel a Contract during the period set out below in Clause 12.2. However, this cancellation right does not apply in the case of the following Goods (unless they are faulty): (a) Goods made to your specifications or Goods which are either clearly personalised or which we identify as non-stocked goods ordered at your request (“Special Order Goods”). We will contact you to let you know if your order contains any such items (b) sealed sensitive electronic Goods (e.g. boiler printed circuit boards) if sealed packages have been opened (c) Goods that have been fitted; and (d) any Goods which become mixed inseparably with other items after their delivery. 12.2 Your legal right to cancel a Contract starts from the date on which we notify you either that we have dispatched the Goods in accordance with Clause 5.2 or that they are available for collection in accordance with Clause 5.3. Your deadline for cancelling the Contract then depends on what you have ordered and how it is delivered, as set out in the table below: Your Contract Your Contract is for a single item of Goods (which is not delivered in instalments on separate days). Your Contract is for either of the following: • one item of Goods which is delivered in instalments on separate days. • multiple Goods which are delivered on separate days Your Contract is for the regular delivery of Goods over a set period End of the cancellation period The end date is the end of 14 days after the day on which you receive the Goods. The end date is 14 days after the day on which you receive the last instalment of the Goods or the last of the separate Goods ordered. The end date is 14 days after the day on which you receive the first delivery of the Goods. 12.3 To cancel a Contract, you just need to let us know that you have decided to cancel. The easiest way to do this is to complete the cancellation form If you use this method, we will e-mail you to confirm we have received your cancellation. You can also e-mail us at firstname.lastname@example.org, contact our Customer Services team by telephone on 0800 368 8815. If you are e-mailing us or writing to us, please include details of your order to help us to identify it. If you send us your cancellation notice by e-mail or by post, then your cancellation is effective from the date you send us the e-mail or post the letter to us. 12.4 If you cancel your Contract we will: (a) refund you the price you paid for the Goods. However, please note we are permitted by law to reduce your refund to reflect any reduction in the value of the goods, if this has been caused by your handling them in a way that goes beyond what is necessary to establish the nature, characteristics and functioning of the goods (e.g. it goes beyond the sort of handling that might reasonably be allowed in a shop. If we refund you the price paid before we are able to inspect the goods and later discover you have handled them in an unacceptable way, you must pay us an appropriate amount. (b) refund any delivery costs you have paid, although, as permitted by law, the maximum refund will be the costs of delivery by the least expensive delivery method we offer (provided that this is a common and generally acceptable method). (c) make any refunds due to you as soon as possible and in any event within the deadlines indicated below: (i) if you have received the Goods and we have not offered to collect them from you: 14 days after the day on which we receive the Goods back from you or, if earlier, 14 days from the day on which you provide us with evidence that you have sent the Goods back to us; (ii) if you have not received the Goods or you have received it and we have offered to collect it from you: 14 days after you inform us of your decision to cancel the Contract. 12.5 We will refund you via the same means of payment as you used to pay for the Goods 12.6 If the Goods have been delivered to you before you decide to cancel your Contract: (a) then you must return them to us without undue delay and in any event not later than 14 days after the day on which you let us know that you wish to cancel the Contract. Unless otherwise agreed with us, you can send them back. Before returning any Goods you must contact us either by: (i) email on email@example.com; or (ii) telephoning 0800 368 8815; or Where Goods have been damaged whilst in your possession we shall not be obliged to accept the return of those Goods. In such circumstances, we will notify you that the Goods are available for re-delivery for which you shall be liable for any reasonable delivery charges incurred. (b) unless the Goods are faulty or not as described (in this case, see Clause 12.7), you will be responsible for the cost of returning the Goods to us. If the Goods cannot be returned by post, we estimate that if you use the carrier which delivered the Goods to you, these costs should not exceed the sums we charged you for delivery; (c) we request that you return all the original packaging where possible to do so and that you supply the advice note accompanying the Goods or other proof of purchase (and for the avoidance of doubt a copy of the email confirming details of the order will not be sufficient for these purposes); and (d) as you are responsible for the Goods until they are returned to us, we ask that you please ensure that you obtain adequate proof of postage with adequate insurance in place. 12.7 Because you are a consumer, we are under a legal duty to supply Goods that are in conformity with this Contract. As a consumer, you have legal rights in relation to Goods that are faulty or not as described. If the Goods are faulty or misdescribed you may have a legal right to end the Contract (or to get the Goods repaired or replaced or to get some or all of your money back). These legal rights are not affected by your right of return and refund in this Clause 12 or anything else in these Terms and Conditions. If you wish to exercise your legal rights to reject Goods you must either return them in person to where you bought them, post them back to us or (if they are not suitable for posting) allow us to collect them from you. We will pay the costs of postage or collection. General 13.1 When using the Website you accept that communication with us will be mainly via electronic means. If we have to contact you or give you notice in writing, we will do so by e-mail or by pre-paid post to the address you provide to us in your order, or by posting notices on the Website. When we refer, in these Terms and Conditions, to "in writing", this will include e-mail. This Clause does not affect your legal rights. 13.2 If you wish to contact us for any other reason, including because you have any complaints, you can contact us by e-mailing us at firstname.lastname@example.org or by writing to us at Chapelry, Walkers Lane, Whittington, Worcestershire, WR5 2RD, quoting the reference “FAO Online Contact Centre”. We will try to resolve any complaints that you have as soon as possible. If you are unhappy with our final response, you may access the European Commission's Online Dispute Resolution Portal available at http://ec.europa.eu/consumers/odr/ 13.3 We will not be liable or responsible for any delay or failure to perform any of our obligations under a Contract if the delay or failure to perform is due to a cause beyond our reasonable control (e.g. strikes or other industrial action by third parties, terrorist attack or threat of terrorist attack, fire, explosion, flood, subsidence or other natural disaster, or impossibility of the use of railways, shipping or other modes of transport). 13.4 This Contract is between you and us. No other person shall have any rights to enforce any of its terms. However, if you give the Goods to a friend, family member or other person as a gift (i.e. for no value in return), that person will have the benefit of our warranty at Clause 11, but we and you will not need their consent to cancel or make any changes to the Contract (including varying these Terms and Conditions). 13.5 We may transfer our rights and obligations under a Contract to another organisation, but this will not affect your rights or our obligations under these Terms and Conditions. Except as provided for in Clause 13.4, you may only transfer your rights or your obligations under these Terms and Conditions to another person if we agree in writing. 13.6 If we fail to insist that you perform any of your obligations under these Terms and Conditions, or if we do not enforce our rights against you, or if we delay in doing so, that will not mean that we have waived our rights against you and will not mean that you do not have to comply with those obligations. If we do waive a failure by you to comply with the Contract, we will only do so in writing, and that will not mean that we will automatically waive any later default by you. 13.7 Each of the paragraphs of these Terms and Conditions operates separately. If any court or relevant authority decides that any of them are unlawful or unenforceable, the remaining paragraphs will remain in full force and effect. 13.8 These Terms and Conditions are governed by English law. This means that a Contract and any dispute or claim arising out of or in connection with it will be governed by English law. You and we both agree to that the courts of England and Wales will have non-exclusive jurisdiction. However, if you are a resident of Northern Ireland you may also bring proceedings in Northern Ireland, and if you are a resident of Scotland, you may also bring proceedings in Scotland 13.9 We reserve the right to monitor and record telephone calls our staff receives and make in order to monitor staff performance and ensure the highest service possible to our customers.
