SABROE packaged ammonia heat pump
Ammonia - the natural choiceAmmonia has a number of characteristics which make it the ideal refrigerant for future refrigeration purposes:
• Ammonia is the only refrigerant with no negative impact on the environment
• No ozone depleting potential (ODP)
• No global warming potential (GWP)
• A well-known and acknowledged refrigerant which has been used safely in refrigeration for more than 100 years
• Ammonia has the best thermodynamic efficiency
• A natural refrigerant which easily breaks down into nitrogen
• If refrigerant leaks should occur they will be easy to detect, as the distinct smell of ammonia serves as a natural built-in alarm
• It is inexpensive and significantly cheaper than other refrigerants
• Known technology and plant design• Better energy efficiency (COP)• Better heat transfer coefficient• Available and low-priced all over the
world• Non-mixable with oil• Less sensitive to humidity in the plant• Smaller compressor - same capacity• Smaller heat exchangers - same
capacity• Smaller circulated quantity
Why choose ammonia?What are the advantages?
SABROE Ammonia heat pump compressorThe natural choice
The natural choiceSabroe ammonia 40 bar heat pump compressors
Types HPO and HPC
Features:
• Ammonia is an ozone-friendly refrigerant• Heat pump systems reduce the CO2 emission• The series covers the entire water temperature range
up to 70°C.• Compared with CFC, HCFC and HFC systems you will
gain the following advantages:- higher efficiency (COP)- reduced compressor size- smaller evaporators- smaller condensers- smaller pipe and valve dimensions
• Capacity range: 100-1500 kW (one compressor)• Multiple applications

ApplicationsSabroe ammonia heat pump compressors are perfectly suited for a large number of applications, such as:
• Heat reclaim for hot/warm water production in ammonia refrigeration plants within the food industry (abattoirs, dairies, ice cream factories, fish processing, freeze drying, breweries, slaughter houses etc.)
• Condenser heat reclaim from refrigeration systems
• Upgrading of industrial waste heat for use in industrial processes, district heating, individual buildings, etc.
• Heat pump systems based on natural heat sources such as sea water, air and geothermal energy
• Special applications such as wood seasoning, fish drying, exhaust gas cooling in power plants, etc.
• Heating in ice rinks or other sports arenas.
• Hot water for baths and swimming pools.
