876 ZEAS, the smart choice for medium and low temperature refrigeration Refrigerating capacity 3.35 kW* Booster ZEAS is available in different capacity ranges from 5 to 40 HP and delivers the required Refrigerating capacity to third party equipment like open showcases, glass door freezers and evaporators Flexible combination refrigeration system Separate groups for medium and low temperature cooling, each with multiple cabinets and different temperatures. This flexibility and energy savings of up to 50% are only possible with ZEAS-systems. Operating range Ambient temperatures: -20°C to +43 °C Evaporating temperatures: -45°C to +10°C +2°C +4°C 0°C +2°C +4°C +4°C 0°C +2°C -20°C +2°C * Te= -35°C, Tc = -10°C, 10 K SH, Tamb = 32°C * Only Zeas. Not applicable for Mini-Zeas and Multi-Zeas R-410A is a lower GWP refrigerant (less than 2,500) than R404A and is fully F-gas compliant. It’s future proof: it can be used even after 2030! R-410A is also: J an easy to handle, common used refrigerant in the air conditioning world, therefore it is easy to find an installer which can work with this refrigerant, compared to CO2, Ammonia and Propane. J an A1 refrigerant, therefore no special safety measurements are required. Contributes to reducing installation cost and refrigerant charge R-410A is a high pressure refrigerant which for the same swept volume can deliver much more refrigeration capacity than standard mid pressure and low pressure refrigerants. This means that for the same delivered refrigeration capacity we can use smaller components, thus reducing the installation cost and the amount of refrigerant charge in the system! Why R-410A? For a capacity of 8.4 kW (Te = -10°C / Tamb = 32°C) Refrigerant charge per used refrigerant (Te = -10°C / Tamb = 32°C) Refrigerant Suction piping diameter R134a 1 1/8” R407A 7/8” R407F 7/8” R448A 7/8” R449A 7/8” R450A 1 1/4” R-410A 3/4” CO2 1/2” 1.60 1.40 1.2 1.00 0.80 0.60 0.40 0.20 0.00 Refrigerant charge (kg/kW) Refrigerant R448A R449A R-410A 1.43 kg/kW 1.43 kg/kW 1.03 kg/kW Banned from 2020 onwards R134a R32 R404A R407A R407C R407F R-410A R448A R449A R450A R452A R507A R513A Refrigerant GWP (based on IPCC report IV) Use of refrigerant in refrigeration system with a refrigeration lower than 40 kW Refrigeration capacity (kW) Swept volume (m3/h) 40 35 30 25 20 15 10 5 0 0 2 4 6 8 10 R450A R-410A CO2 R407A R449A R448A R407F R134a Delivered capacity per used refrigerant 4,000 3,500 3,000 2,500 2,000 1,500 1,000 500 0
