In this video, we dive into the crucial topic of emergency service calls from evaporator freezing in HVAC systems and how the APR Control is your ultimate solution. Evaporator freezing can wreak havoc on your system's efficiency and longevity, but with the APR Control, you can prevent it once and for all!
In this video, we cover how neglected maintenance can lead to failed compressors and how the APR Control can help. Routine maintenance is a crucial aspect of HVAC that is often overlooked. It is important to take proactive equipment care to avoid mechanical failures such as failed compressors! In the world of HVAC, preventing problems rather than just fixing them leads to happy customers – and can ensure long-term service customers. With the APR Control, you have the power to make it happen. Whether you're a Contractor/Service Technician, Facilities Manager or Building Owner, or simply curious about the Rawal APR Control Valve, you'll find something valuable in this video. 🔥 Highlights: The APR Control’s continuous capacity modulating ability can stop costly compressor failures due to any low airflow scenarios – potentially caused by neglected maintenance. The APR Control can serve as an insurance policy against the unbudgeted expenses from failed compressors due to neglected routine maintenance.
Achieve total comfort by mastering your thermostat with the APR Control. Every facility manager, contractor, or technician has heard the complaints, “It’s too hot, too cold or it doesn’t feel quite right in here!” Remember, air conditioning isn’t about air cooling, it’s about moisture removal to improve comfort. Even in this new era of thermostat controls, most commercially available thermostats do not address or control humidity. Learn how APR Control can unleash ultimate precision in your air conditioning system that empowers you to satisfy both temperature and humidity to perfection. No more settling for too hot or too cold – with APR Control, you're in command.
Rawal Devices’ Senior Technical Engineer, Jason Santos, walks you through how to adjust the APR Control and also covers some of the reasons why you would adjust. We’ve often called the APR Control a “set-it and forget-it” solution as it comes factory set to modulate at approximately 120psig for R-410A (maintaining a 40°F evaporator coil temperature). For most standard DX comfort cooling applications, the APR typically does not require adjustment.
Rawal Devices’ Senior Technical Engineer, Jason Santos, walks you through how to properly install the APR Control on a standard DX rooftop unit. From preparation, measuring and cutting, to brazing – Jason covers all of the necessary steps you need to take in order to successfully install the APR Control valve.
Rawal Devices’ Senior Technical Engineer, Jason Santos, reveals that all DX systems are inherently oversized by design. Yes even yours! Having an oversized system will ultimately lead to short cycling of the compressor, creating an uncomfortable indoor environment because of high humidity. However, Jason will explain how the APR Control is the perfect solution for an oversized air conditioning unit that will help solve or prevent these problems from occurring.
Learn about why evaporator freezing and liquid slugging occur, and why you need the APR Control to prevent these issues from occurring! Rawal Devices’ Senior Technical Engineer, Jason Santos, helps you understand the common contributing factors of evaporator freezing and liquid floodback, leading to compressor failure.
