Description
Under its product brand Sabroe, Johnson Controls has developed a freeze package optimized for industrial cascade systems and a high-pressure reciprocating compressor, to be used also in heat pump applications.
Basic specifications
- Length x Width x Height (mm): 5200-6700 x 2600-3200 x 2800-3200
- Weight (kg): 8000-18000
- NH3 charge (kg): 45-155
- CO2 charge (l): 800-1650
- based on a cascade system combining the advantages of CO2 on the low-temperature side and ammonia on the high-temperature side
Advantages:
- Low power consumption: 45% less compared to single-stage systems with economisers; 5-15% compared to two-stage systems
- Compact design: saves space, gives greater flexibility
- Very small ammonia charge: installation of large-capacity, low-temperature plants with only limited refrigerant restrictions is possible
- Clear separation of ammonia and CO2: eliminates risk of damage in production in case of leaks
- Automatic oil recovery system in both circuits: only minimum maintenance required
- Low operating costs
