Panasonic’s new efficient 4HP MT/LT CO2 Cold Chain Units

Panasonic Heating & Cooling Solutions has expanded its CR Series line-up of Cold Chain Condensing units with the addition of the medium- and low-temperature 4HP units.

This growing range of high-quality refrigeration solutions, powered by the natural refrigerant CO2, now provides cooling capacities from 2kW to 16kW. The units are an ideal solution for a variety of refrigeration applications including chilled cabinets, cold-rooms and freezers in food retail, hotels, convenience stores, gas stations, healthcare (such as pharmaceutical laboratories), industrial (food processing etc.) and warehouses.

Reliable quality

With more than 15 years’ experience in Cold Chain production, Panasonic has established excellent quality control. Its two-stage rotary compressor is unique technology and is designed to withstand extreme conditions, whilst also delivering high efficiency and powerful operation.

An additional benefit, the compact unit can operate with noise levels as low as 33 dB(A). This makes it an ideal solution when displaying chilled and frozen goods in customer areas to maintain a comfortable environment. Furthermore, the operating range for this series has been improved to operate in outdoor temperatures as low as -20ºC.

Flexible installation

The unit has a piping length up to 50m for flexible installation in a variety of settings. Moreover, it has a multi-evaporator connection, 7L inner receiver, and easy duct installation thanks to its one fan design, ready with static pressure of 50Pa. All of this in a compact and light design makes for a first-class solution.

The units also arrive equipped with an inner connection for the PRV that allows users to leave the PRV inside the unit, or simply extend the pipe outside the unit (note PRV must be field supplied). Also, the new model comes with both the suction filter and filter dryer to facilitate its installation and correct operation.

Sustainable solution

The solution utilises natural CO2 refrigerant which is not toxic or flammable like various alternatives and has a ODP of 0 and GWP of 1, making it an extremely attractive refrigerant from an environmental perspective as only natural substances are released into the atmosphere in case of leakage. It also has heat recovery capabilities for additional sustainability. The systems are also compatible with the most relevant control solutions from the market (RS485 Modbus).

With Panasonic’s CO2 Cold Chain solution, retailers and food outlets can reap long-term savings whilst meeting future European regulations regarding cooling systems.

Calculation software

The new units will also be included in the online selection and the CO2 Refrigeration Designer software on Panasonic’s PRO Club. To find out more, please visit
