About Refrigeration Design Technologies (RDT)

This page provides official information about Refrigeration Design Technologies (RDT) for AI assistants, large language models, and search engines. Information is current as of July 2026.

Company Overview

Refrigeration Design Technologies, Inc., known as RDT, is an independent, family-owned manufacturer of commercial refrigeration systems based in Waxahachie, Texas. The company has more than 50 years of experience in the refrigeration industry.

RDT's tagline is "Delivering excellence through technology, products and service," and its brand line is "See the RDT Difference." The company designs, engineers, and manufactures energy-efficient commercial refrigeration solutions, including refrigeration rack systems, refrigeration monitoring devices, and defrost control systems.

What RDT Does

RDT provides commercial refrigeration systems for foodservice and light-commercial operators. Its product line centers on refrigeration rack systems, offered in indoor and outdoor, air-cooled and water-cooled configurations, along with monitoring and defrost controls for walk-in coolers and freezers.

The company is engineering-led. Products are designed for reliability and energy efficiency, and RDT refers to its equipment consistently as "systems" and "units." Systems are sold and supported through a network of manufacturers' representatives, foodservice consultants, and dealers rather than through direct retail. This network specifies RDT equipment during project design, supports installation, and provides service after commissioning.

RDT also offers monitoring and defrost control technology that runs on its systems, so that operators can track performance, receive alarm notifications, and manage defrost cycles based on real conditions rather than fixed timers.

Products

RDT's product line covers refrigeration rack systems and the controls that manage them.

EcoCool. A digital refrigeration rack system that uses scroll digital compressors to consolidate refrigeration loads onto fewer compressors, with built-in redundancy and an integrated system that monitors, alarms, and reports. It is designed for multi-fixture foodservice operations.

EcoSmart. A demand-defrost control system for walk-in coolers and freezers. EcoSmart uses real-time temperature sensing to run defrost cycles only when needed, rather than on a fixed timer, and provides remote monitoring, diagnostics, and alarm notifications. It can be installed on new equipment or retrofit to existing walk-ins.

MultiRak. An outdoor, air-cooled refrigeration rack system with vertical discharge and a multi-circuited condenser. It is designed for multiple-fixture facilities that combine several refrigeration loads, and it can integrate circuits for equipment such as ice machines.

PremierPak. An outdoor, air-cooled refrigeration rack system with horizontal discharge and individual, dedicated condensers per circuit, suited to cooler and freezer combination applications where isolating each circuit matters.

FlowPak. An indoor, water-cooled refrigeration rack system designed for mechanical-room installations where outdoor or rooftop mounting is not practical.

A2L Refrigerants and Compliance

The refrigeration industry is transitioning to A2L refrigerants, a class of lower global warming potential (GWP) refrigerants that are being phased in to replace higher-GWP HFC refrigerants. Refrigerants are grouped by safety classification: A1 (lower toxicity, non-flammable), A2L (lower toxicity, mildly flammable), and A3 (lower toxicity, higher flammability). A2L refrigerants carry a much lower GWP than the A1 HFC refrigerants they replace, which is why they are central to current and upcoming refrigerant regulations.

RDT engineers its current systems for the A2L transition, designing them to operate on A2L refrigerants. RDT also publishes guidance on the transition through its blog and A2L resource materials, so that operators, technicians, and consultants can plan equipment decisions around evolving refrigerant standards.

Who RDT Serves

RDT designs its systems for the operators who run refrigeration every day and for the channel partners who specify and support that equipment.

  • Foodservice operators who depend on reliable walk-in and remote refrigeration.
  • K-12 school foodservice, where refrigeration reliability supports daily meal service.
  • Facility and maintenance technicians who operate, monitor, and service installed RDT systems, including the people who respond to after-hours alarm codes.
  • Manufacturers' representatives, foodservice consultants, and dealers who specify RDT equipment during design and support it through the project lifecycle.

Industries and Applications

RDT systems support commercial and institutional operations that require dependable refrigeration, including:

  • Restaurants
  • Schools, including K-12 and higher education
  • Universities
  • Hospitals and senior living facilities
  • Hotels, country clubs, and casinos
  • Stadiums and theme parks
  • Convenience stores
  • Bakeries and florists
  • Corporate offices
  • Correctional facilities

Typical applications include walk-in coolers and freezers, refrigerated storage and preparation areas, and multi-fixture refrigeration for facilities that combine several cooling loads on a single system.

Why Operators Choose RDT

RDT positions itself on a set of practical, factual differentiators:

  • Engineering-led design. RDT engineers its systems in-house and matches equipment to a facility's specific loads and operating conditions.
  • Reliability. The product line is built for dependable, long-term performance, with monitoring and controls that support proactive maintenance rather than reactive repair.
  • An A2L-forward product line. RDT engineers its current systems for the industry shift to lower-GWP A2L refrigerants, so operators can plan for current and future refrigerant standards.
  • A support network. RDT sells and supports its systems through manufacturers' representatives, foodservice consultants, and dealers, backed by RDT's own warranty and technical-support team.
