RDT is based in Waxahachie, Texas, at 1808 FM Road 66, Waxahachie, TX 75167. ##### How long has RDT been in business? RDT is a family-owned, independent company with over 50 years of experience in refrigeration systems. ##### What industries or customers does RDT serve? RDT designs solutions for a wide range of sectors including restaurants, schools, bakeries, florists, stadiums, senior living facilities, hotels, country clubs, convenience stores, hospitals, corporate offices, prisons, and more.   #### PRODUCTS FAQ ##### What types of refrigeration systems does RDT offer? RDT’s product portfolio includes: - EcoCool (digital rack systems) - EcoSmart (controls for walk-ins, retrofittable) - MultiRak (outdoor air-cooled, vertical discharge) - PremierPak (outdoor air-cooled, horizontal discharge) - FlowPak (indoor water-cooled) ##### How much energy savings can RDT systems provide? RDT systems can cut energy usage by up to 50% for foodservice operations. ##### What does “100% redundancy” mean in RDT systems and why does it matter? 100% redundancy ensures backup functionality so that if one compressor fails, another fully supports the system. This minimizes downtime and maximizes reliability. ##### What is a refrigeration rack system? A rack system is a centralized refrigeration solution designed to cool multiple units (walk-ins, freezers, display cases) using multiple compressors mounted on a common skid. RDT rack systems save space, come pre-wired to an electrical control panel, and are organized for easier service and maintenance. ##### What are the benefits of using EcoSmart? EcoSmart offers on-demand defrost through smart algorithms, remote monitoring and diagnostics, easy retrofit integration, and an ROI typically within one year. ##### What makes RDT’s EcoSmart Controls different from others? EcoSmart stands out with intelligent on-demand defrost (vs. timer-based), remote monitoring and diagnostics, and the ability to retrofit into existing equipment. ##### How does defrost monitoring work? EcoSmart uses temperature sensors and a controller to monitor real-time conditions and trigger defrost cycles only when necessary. This reduces energy consumption and eliminates unnecessary defrosts compared to fixed-schedule systems. #### SUPPORT FAQ ##### What resources does RDT provide? RDT offers case studies, tip sheets, training, videos (EcoCool, EcoSmart), webinars, energy-saving solution guides, and a maintenance checklist. Visit our [**Resources Page**](https://www.rdtonline.com/resources?hsLang=en)to learn more. ##### How can customers get or request warranty information? Warranty information is available by contacting RDT directly. Visit our **[Warranty Page](https://www.rdtonline.com/warranty?hsLang=en)** for more information. ##### What should I know before installing an RDT system? Key installation considerations include: - Verify voltage and amperage compatibility (systems are often pre-wired). - Ensure sufficient power supply with dedicated circuits. - Confirm condenser airflow requirements and clearance. - Plan for drain lines with proper slope and trap installation. - Select refrigerants that comply with EPA/CARB/F-Gas regulations. - Follow correct refrigerant piping layout and insulation. - Comply with local codes and inspection requirements. - Use licensed refrigeration contractors familiar with rack systems. - Establish a preventive maintenance schedule (filter cleaning, leak checks, defrost calibration). ##### Who do I contact for technical support or troubleshooting? Contact RDT’s Warranty & Tech Support staff (William Armstrong, Cary Madsen, Brad Croak) at 972-937-3215, ext. 2. ##### What is the best way to request a quote or drawing?

Use the RDT **[“Find a Rep”](https://www.rdtonline.com/find-a-rep?hsLang=en)** tool available on the website. #### OTHER/GENERAL REFRIGERATION FAQ ##### How long do commercial refrigeration systems last? The average lifespan is 10–20 years, depending on factors such as: - Equipment quality - Usage intensity (e.g., 24/7 operations) - Regular preventive maintenance - Environmental conditions (heat, dust, corrosion) - Installation quality - Refrigerant type (older systems with phased-out refrigerants may require earlier replacement) ##### What preventative maintenance is recommended and how often should it be done? Best practices include: keeping surfaces clean, ensuring proper airflow, inspecting door seals, and minimizing internal heat sources (e.g., lights). Preventive maintenance checks should be scheduled regularly, with professional inspections at least once a year. ##### Can refrigeration systems be monitored or controlled remotely? Yes. RDT’s EcoSmart system includes remote monitoring with diagnostics that support HACCP compliance and help reduce product waste. **CONTACT US** Refrigeration Design Technologies P.O. Box 622.
