ICOOL, within the Ninhua Group, is the first local company to export natural refrigerants in entire China. In 2012, almost 30000 tons of refrigerants were exported. ICOOL specializes on a range of natural refrigerants including propane (R290), isobutane (R600a) and carbon-dioxide (R744). These are non-ozone depleting, non-corrosive, non-toxic and non-global warming potential alternatives to synthetic refrigerants. Natural refrigerants can be used for a range of applications in both commerical and industrial markets. ICOOL instructs their customers on the correct use and application of natural refrigerants, particularly hydrocarbons. They deliver the clear message that hydrocarbon refrigerants are already in use in many places and that the application of them is not as dangerous as generally believed. …

Direct fired biomass absorption cooling unit Biomass trigeneration allows for combined cooling, heating and power generation. Using solid biofuels on a small scale decentralizes biomass consumption and decreases logistical issues. An environmentally-friendly option for buildings where the heating needs are higher than the cooling demand. …

The ONYX series are simple, integrated transcritical booster systems for medium (MT) and low temperature (LT) supermarket applications designed by Commercial Refrigeration Services (CRS) South Africa. The ONYX CO2 booster system makes use of parallel compression and ejectors, increasing energy efficiency by 25-35% and making CO2 a viable refrigerant choice even in high temperature regions. ONYX uses a two-stage compression cycle with a common condenser and liquid line for MT and LT applications. The two-stage design prevents significant energy losses as no big heat exchangers are required to condense the LT side. The integrated multi-temperature solution thus allows each ONYX unit to fully exploit the advantages of CO2. …

The CDU-L condensing unit by Sanden uses a 100% CO2 transcritical cascade architecture, ensuring reliability and quality for application in convenient stores and small cooling capacities. Benefits of the unit include a negligible GWP of 1, large product range available for medium and low-temperature applications, quiet operation as well as up to 40% reduction of piping costs at installation. After rigorous field-testing and improvement in Japan, the CDU-L unit was launched on the European market. …

Thermo King’s CryoTech transport refrigeration technology uses a recycled natural refrigerant in a simple, robust system to eliminate both noise and emissions, granting your vehicles access to restricted zones night and day. The CO2 refrigerant used in the CryoTech system is sourced from recycled waste gas captured from the production of fertilizer and other chemical compounds. The refrigerant would otherwise be released into the atmosphere as a by-product, such that there is no cumulative global warming effect caused by its use in the CryoTech system. Moreover, CryoTech technology has a very low operating noise, ensuring conformity with the Piek standard of 60dB(a) limit during nighttime deliveries in urban areas. Thermo King’s CryoTech technology is the ideal solution for transport refrigeration, meeting stringent environmental legislations will ensuring highest product quality. …

New Family of DLV Variable-Speed Compressors provides 40% energy savings and superb cooling efficiency in a sustainable manner, as well as providing a unique solution that is suitable for both LBP and MBP applications. The compressor family is characterized by being efficient, compact, and environmentally friendly using the refrigerant propane (R290) with a low global warming potential, GWP3. The DLV compressor comes with the new CCD® controller which features a high IP54 protection class. Its common interface enables case controllers from all major suppliers and uses speed control as well as adaptive energy optimization (AEO). The controller also provides a high starting torque and can start against differential pressure. Moreover, integration and customization is made easy due to the acclaimed TOOL4COOL® software. …

Introduced by Efficient Energy in February 2016, the eChiller is the only centrifugal chiller in the 35-kW refrigeration capacity range that uses pure water (R718) as a refrigerant. The eChiller technology is based on an energetically optimized and direct technical implementation of the thermodynamic cycle. It comprises the direct evaporation, compression, condensation and expansion of water in a closed-loop cycle. This innovative technology can save up to 80% electricity compared to conventional cooling systems. In the near future, chillers using synthetic refrigerants will no longer comply with regulatory requirements. Ever increasing energy costs place an addition burden on refrigeration. As such, far-sighted investments into innovative chiller technologies are of great significance. …

Natural Ecological Efficient and Reliable Chiller Solutions The EKO.E - RKO.E line ranges from 10-1290 kW and is an all natural chiller solution. The system uses the hydrocarbon R290 as refrigerant, which is both sustainable and energy efficient. The compressor is a reciprocating semihermetic type (pistons or compact-screw), fixed on anti-vibration system and complete with pressure lubrication system. The compressor is mechanically optimized for use with Hydrocarbons and built in according to Directive ATEX 94/9/EC for the safety requirements: Zone 2, Gas group IIB. To ensure high-safety-level the unit is equipped with a special gas detector for flammable gases, including two alarm levels and microprocessor control with LED status indicator. Refrigerant: R290 (Propane) Cooling capacity: Up to 1.230kW Energy efficiency: High, free-cooling version also available Energy efficiency rating: Up to 4,55 …

R290 Natural Chiller for Server Room sustainable application Besides its longstanding tradition in the construction of systems for technological plants, Euroklimat has great expertise in finding ad hoc solutions to solve special problems. In this particular case, the client’s Server Room is located in Birmingham and the installation consists of two small water refrigerators 10 kW each that are completely different, but which have the characteristic of being installed on the same structure, working in standby with each other. The automatism for managing the switchover in the event of a failure is controlled externally by the centralised control systems of the computer centre. The “safety” and “continuity” of the supply of the cooling energy are fundamental for the John Lewis Partnership in this context, but, together with this, we mustn’t forget the use of natural refrigerants, such as Propane to safeguard the environment, an indisputable request from clients and one of Euroklimat’s product strengths, too. Refrigerant: R290 (Propane) Cooling capacity: 2 x 10 kW (100% total redundancy) Energy efficiency rating: 3,47 …
