Thank you, Jim and thank you everyone for joining us today. Once again, I want to start today's call with the sincere hope that everyone listening, and your families are safe and healthy. Although it has been only eight weeks since our last earnings call, the momentum we spoke about has continued to build. We completed the two live well field trials in Texas and New Mexico announced in our last call. We are currently at another and have two more planned. We held another successful joint marketing webinar with DuPont, this time hosted in Mandarin and focused on the Chinese market. Our R&D testing has delivered compelling data on our CO2 refrigeration PX, and we are finalizing design and testing in preparation for beta testing. And, of course, our core desalination business continues to surge forward delivering a new record high first quarter product revenue. In addition, we are proud to say that we have been shortlisted for the Best 1st Time Sustainability Report with the Corporate Register Reporting Awards. Corporate Register is the world's largest corporate responsibility and ESG report directory. In today's call, I will update you on our desalination business, industrial wastewater, VorTeq, and our refrigeration efforts. With that, let us start with our record-setting desalination business. Our desalination business started the year off in robust fashion, with record-setting quarterly product revenue. The $28.9 million that we posted is 52% higher than the year ago, and was once again led by our mega project segment. Demand for these large-scale projects stems from the global need for more water, and is why our desalination business has averaged solid double line growth since 2015. Our growth outlook remains strong at 10% this year and upto 25% in 2022. While desalination is one tool to address the world's water needs, how we manage existing water resources is another, which brings us to our Ultra PX energy recovery device and industrial wastewater. Over the last eight weeks, we have focused on building our pipeline for potential projects. The sales cycle for these projects are typically between 12-18 months long. Most projects in the pipeline this year had already been designed either with thermal or an RO process using a competitive ERD; therefore [Technical Difficulty] we must work hard to insert the Ultra PX in the bidding process. The fact that we have landed two projects so soon after launching shows the focus of our sales team, and the strength of our technology. As we further educate the marketplace, together with partners such as DuPont, we should make deeper inroads as customers begin to spec in ultra high-pressure RO, and our Ultra PX into future designs. We will have more updates on industrial wastewater in the coming quarters as we further define the market and make inroads on sales. Our initial Ultra PX sales will help reduce energy consumption while removing toxins from the industrial wastewater of a natural gas plant in China and a chemical manufacturing plant in India. The first two sales demonstrate the broad applicability of the Ultra PX to different industries. In the near term, we are focused on further expanding the breadth of industries able to benefit from the use of reverse osmosis and our Ultra PX in addressing their wastewater treatment needs. Let me now turn to VorTeq. During our call last quarter, we highlighted the two live well field trials where the VorTeq was deployed. We participated in more than 25 frac stages and demonstrated that the VorTeq can effectively perform without interrupting or impeding normal frac operations. We integrated successfully with Liberty's system and proved the VorTeq can withstand live frac conditions and unplanned events such as stalled pumps, pressure fluctuations and other issues commonly occur during a frac job. We thank Liberty and their end customer for accommodating us on-site. Following the success of those field trials, we have joined Liberty and the same end customer at a new well site in West Texas where we are currently operating. We are using this field trial to test changes that we made to the VorTeq based on learnings from the first two field trials and to gather more data to validate our customer value proposition. We are planning two additional field trials in May; again with Liberty and the same large independent producer. The main gating item to finalize our decision on commercialization remains extending the service life of the VorTeq cartridges. Without this, we cannot achieve profitable commercialization. We have made important progress towards gathering the information needed to make a final decision, which we promised by the end of June. But because that timing is mid-cycle we have decided to give shareholders our decision at our Annual Shareholders Meeting on June 10. With our decision date nearing, we are evaluating multiple options to generate a return on our VorTeq investment, which is why these additional field trials are important. Some of the choices we are considering include commercialization on our own or with a partner, a joint venture, selling or licensing the IP, or seeking other uses for the VorTeq outside of fracking. Above all, we are focused on monetizing our hard work and investment in the VorTeq, and the efficiency this technology can deliver. We look forward to updating you on our plans on June 10. For those who are unable to join us for that meeting, we plan to publish the transcript in our investor relations website. Now I turn to Refrigeration. Last quarter we announced the PX capabilities to expand and compress gas. We also identified commercial refrigeration which includes the stores such as super-markets and mega-markets, as our first target market. I will now explain why this capability is so important to the commercial refrigeration industry. In short, we believe our company's ERI can play a key role in supporting and accelerating the transition from extremely environmentally harmful greenhouse refrigerants, CFCs and HFCs, to environmentally neutral natural refrigerants, the most promising of which is carbon dioxide or CO2. More than 100 countries have signed on to the Kigali Amendment, an amendment to the Montreal Protocol, and this year the United States and China have publicly committed to signing. While the Montreal Protocol successfully reduced ozone layer harming CFCs, or CFCs, the Kigali Amendment is aiming at phasing out HFCs. HFCs are greenhouse gas refrigerants that can contribute thousands of times more to global warming than CO2. According to the National Academy of Sciences, eliminating HFCs alone could potentially reduce global warming by upto half a degree centrigrade -- I'm sorry, half a degree celcius. The goal of the Kigali Amendment is an 80% reduction of HFC use by 2047. With certain countries and regions are already accelerating the pace by implementing strict targets for the 2020s in order to reach the 2047 goal. The European Union is leading the way and has banned sales of many types of HFC usage by 2022. California is seeking to reduce HFC usage by 40% by 2030. The transition away from HFCs and to CO2 refrigerant systems is accelerating. For the $55 billion refrigeration and air-conditioning industry, moving away from HFC means moving to natural refrigerants such as ammonia or CO2. Ammonia is potentially flammable and explosive; therefore it has been limited to large industrial systems away from dense populations and requires 24x7 constant on-site technical crew maintenance. CO2 is stable, more benign, and therefore the safer choice. Over 35,000 CO2 units have already been deployed, primarily concentrated in northern parts of Europe where the ambient temperatures are mild. This regional choice is likely due to the added costs of running CO2 systems compared to the traditional HFC systems as the cost premium for CO2 systems increases with warmer ambient temperature. Energy recovery devices, ERDs, have been incorporated into CO2 systems to mitigate some of the cost premium. Of the energy recovery devices on the market, we believe our PX alone may be able to reduce the operating costs enough for CO2 systems to compete outside of mild climates. Refrigeration systems work via a cycle where refrigerant is pressurized, then depressurized to carry heat away from objects such as food, in the case of a supermarket. The heat is then discarded into the atmosphere which is at lower temperature, and the refrigerant is recycled through the system to again carry away more heat. At an ambient temperature of 95 degrees Fahrenheit or 35 degrees Celsius, CO2 refrigerant must be pressurized to above 1,300 pounds per square inch, PSI, to achieve this cycle, whereas HFCs only needs to be pressurized to around 300 PSI to achieve the same result. To reach the higher PSI pressure needed for CO2 systems, more electricity must be consumed. The higher pressure and the corresponding increase in electricity needed for CO2 systems have led to the use of energy recovery devices. Without energy recovery device, the additional operating cost of a CO2 system in warmer climates could be prohibitive, and the transition to CO2 would likely not occur without the draconian push of environmental regulation. Current CO2 systems in the market utilize an energy recovery device called an ejector. However, the efficiency limitations of the ejector mean that the economics of CO2 systems outside of the mild northern Europe region are not very good. ERI's PX offers a potential solution to this higher temperature hurdle. Rigorous tests in our labs have shown that our PX may reduce the existing operating cost disadvantage of CO2 refrigeration systems today in warmer climates, thereby allowing the systems to better compete on cost. In fact, our test results show that the performance of the PX actually improved relatively as the ambient temperature gets hotter. This relative improvement occurs because as temperatures rise the pressure differential needed to create the refrigeration cycle also increases. While the ejector can only manage a 200 PSI differential boost, and therefore work within a limited temperature range, our PX's ability to manage this differential boost is unlimited. Meaning, we improve as temperatures increase. We are now finalizing our product development. In addition, we will begin engagement with global commercial refrigeration companies and original equipment manufacturers to prove our product in system level beta tests and to establish future sales distribution. If you would like further details on this technology, we have published a new page on our corporate website. In summary, we carried our last year's strong momentum to this year, starting 2021 off in record fashion. Our core desalination business remains strong; we are building momentum in our efforts to educate the industrial wastewater industry. On the benefits of reverse osmosis and our Ultra PX; we are at our third VorTeq field trial of the year and have two more planned as we near our VorTeq commercialization decision. Finally, our PX for refrigeration have shown very compelling testing results, and we are actively seeking beta test partners. Our disciplined diversified growth is emerging and opening up new potential solutions to accelerate the environmental sustainability of new markets. And with that, I will hand it over to Josh.
