“Our dream was to create a premium quality, environmentally friendly and simple to install split DOAS that delivered the absolute best overall performance and value in the industry.”

Like our Natatorium Protocol Series systems, our DOAS split units have the lowest refrigerant charge in the industry. They do not require site refrigeration work, have the lowest cost to install and are exceptionally reliable. We then added our WebSentry® Technology with 24/7 internet monitoring and remote control and gave it our unprecedented one-year labor warranty on top of our standard two-year parts Warranty (with WebSentry® connected at start-up)

If quality reliability, energy efficiency and the best warranty in the business are what you’re looking for, then look no further than Seresco’s OA Series DOAS technology for your ventilation requirements.
