Warranty information: Kysor Warren warrants to the original purchaser for a period of one year from the date of original installation or 12 months from the date of shipment.


Product: Remote refrigeration systems

Details: Many of these redesigned remote refrigeration systems utilize Copeland Scroll™ compressors along with environmentally friendly R-448A/R-449A refrigerant. All low-temp units now come standard with scroll compressors, and medium-temp models are available with both hermetic and scroll compressors, depending on the horsepower rating. The expanded M-Series condensing units are available in sizes ranging from ¼ to 15 hp.

End user benefits: The Master Controller features Web2Walk-In software, which allows remote monitoring and adjustment of walk-ins. A new defrost function monitors coil temperature and automatically turns on evaporator fans for a short time when the coil is warm to melt accumulated frost and ice from the fan guards. This prevents ice formation from blocking the cold airflow, resulting in more efficient cooling and lowering the risk of temperature fluctuations inside the walk-in caused by the constant opening and closing of walk-in doors.

Serviceability features: The expanded offering of evaporator coils, including new low-profile models, are designed for easy serviceability and maximum efficiency. Web2Walk-In software can pinpoint walk-in performance and maintenance issues, eliminating the need to enter the walk-in or access rooftop equipment to monitor or adjust the refrigeration system.

Warranty information: Manufacturer did not specify.


Product: Refrigeration systems with Copeland Scroll compressors and optional Enviro-Control™ electronic controller system

Details: Scroll compressors provide customers with highly engineered, energy-efficient, quiet refrigeration systems with increased reliability and extended equipment life due to fewer moving parts. The optional Enviro-Control electronic controller system for walk-in refrigeration is designed to increase reliability, connectivity, and food safety while reducing operating costs.

End user benefits: The Enviro-Control offers precise and reliable temperature control, as well as more complete removal of ice build-up in evaporator coils, which can lead to loss of coil performance and food spoilage. The interface located on the front of the evaporator coil allows users to adjust many functions of the refrigeration system. The controller offers the ability to receive alerts, text messages, and emails and remotely control the evaporator from a phone, computer, or tablet.

Serviceability features: It offers optional data logging with the last 30 days of data in 10-minute intervals, which provides food safety verification as well as troubleshooting.

Warranty information: Manufacturer did not specify.


Product: Walk-in coolers and freezers

Details: Each custom-built Polar King walk-in is constructed with a seamless fiberglass design, which keeps the insulated structure completely intact while preventing moisture retention and bacteria formation. Options include scroll compressors, choice in refrigerants (R-404A, R-448A, and R-449A), and KE2 controlled environment systems. All walk-in units are designed to comply with the high-velocity hurricane zone of the Florida building code and Miami Dade approval.

End user benefits: Over time, traditional metal panel walk-in units can suffer from moisture retention, lowering the R-value of the insulation and thereby reducing the overall effectiveness and efficiency of the unit. With seamless fiberglass construction, Polar King walk-in units prevent moisture penetration, retaining the R-Value of the insulation. This will not only extend the life of a walk-in cooler or freezer but also provide a long-term return on investment.

Serviceability features: All units ship fully assembled and require no on-site installation or refrigeration work. The refrigeration has been installed and tested at the Polar King factory, and all that is required to put the walk-in cooler or freezer into operation is an electrical connection.
