PRODUCTS
FAQ

What types of refrigeration systems does RDT offer?
RDT’s product portfolio includes:
  • Eco-Cool Series (digital rack systems)
  • Eco-Smart Series (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 Eco-Smart?

Eco-Smart 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 Eco-Smart Controls different from others?
Eco-Smart 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?

Eco-Smart 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.

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 Eco-Smart system includes remote monitoring with diagnostics that support HACCP compliance and help reduce product waste.
