Wide capacity range gas cooler series, created for small or large transcritical CO2 systems with high pressure. This product is perfect for green and climate-friendly solutions and is suitable for commercial or industrial buildings with medium power demand. Available heat capacity is up to 1 MW upon nominal conditions (when Tin is 115°C, Tout is 33°C and Tamb is 35°C and pressure is 91,7 bar). V shaped construction, assembled with inner 7,94 x 0,54 mm grooved copper tubes, aluminum or copper fins and EC fan motor technology. The galvanized steel and powder coated frame can be designed in various sizes.

CO2 Cascade units are perfectly suited for high temperature climate. This system consists of two refrigeration systems connected via heat exchanger, where one evaporates, the other condenses. Such combination provides either low temperature refrigeration or both: low and medium temperature refrigeration with different refrigerants. Low temperature units can be designed with CO2 and a flooded system to ensure better heat exchange, while medium temperature units obtain a truly cost-effective and environmentally friendly solution when produced with HFC and HC refrigerants. At high ambient temperatures, conventional refrigeration systems require a large amount of energy, whilst propane works perfectly in such conditions. GREEN SOLUTIONS | This unit is a part of Refra‘s environmentally friendly product group, as it is made using natural refrigerants. Such low GWP solutions are designed to have better efficiencies and capacities, as well as less environmental damage.

CO2 Compact systems are designed for small retail shops and can be manufactured for medium temperature cooling. Based on Carel HECU system for complete management of condensing units fitted with BLDC compressors, these products can be adjusted remotely. The serial connection between the condensing unit and the evaporators controlled by MPXPRO represents one of the main features of this solution, contributing to the energy efficiency and reliability of the entire system. The built-in plug and play interface provides the ability to install and set up the unit extremely quickly and easily.

Free cooling system consists of a heat exchanger that cools down glycol mixture by using low temperature ambient air. When outdoor temperatures are lower relative to indoor temperatures, the system utilizes the cool outdoor air as a free cooling source. These energy-efficient units are perfect for industrial refrigeration or air conditioning processes, as they help to reduce mechanical energy consumption up to 80% and reduce maintenance costs as well as environmental impact. Comprehensive modular frame construction is assembled with high-quality EC fan motor technology, finned tube heat exchangers, 3-way valve and circulation pump. The galvanized steel and powder coated frame with a reliable insulation material ensures proper unit protection.
