Together with you, we are checking all possible cooling consumers, their sizing and their simultaneities. This allows us to prepare a first proposal. Options, like multi stage cooling systems, ice banks, heat recovery systems or further possibilities for energy saving will then be discussed in detail. Promising: The Indirect Cooling System Flowing Diagram AMMONIA – THE IDEAL REFRIGERANT FOR INDUSTRIAL REFRIGERATION • safe While ammonia, like many other substances, can displace oxygen or become considered toxic if released in sufficient quantities into a poorly ventilated area, ammonia itself is not a cumulative poison. It is difficult to ignite and has limited explosive potential. The long and successful use of ammonia in industrial closed circuit refrigeration systems proves that its hazards are minimal. A properly designed refrigeration plant, developed and tested by a reputable manufacturer makes the use of ammonia as refrigerant as dependable and safe as to use steam, electricity or any of the halocarbon refrigerants. • self alarming The distinctive, quickly detectable odour of ammonia serves as its own warning agent. If a leak occurs the in-plant service personnel is alerted much before ammonia gets to a dangerous concentration. • efficient It is a fact, that ammonia in comparison to other substances can serve its purpose with by far the least consumption of energy. Ammonia has a high volumetric refrigeration efficiency, which reflects positively on the size of the compressor and the dimensions of the piping. It shows excellent heat transfer properties, which becomes evident in small heat exchangers, comparatively high evaporation temperatures and low condensation temperatures resulting in high coefficients of performance (COP). Ammonia plants are easy to install and operate, highly reliable and easy to modify or expand. • non polluting Ammonia has no ozone depletion potential, no direct greenhouse impact and it’s indirect impact is comparatively low due to the high efficiency. In nature ammonia is produced by biological processes and is naturally decomposed. The consequent preference of the outstanding refrigerant ammonia would effectively support the goal of the world community to reduce CO2 emissions. • CFC alternatives If the use of ammonia is not possible, HANSA INDUSTRIANLAGEN provides a wide range of optimized refrigeration units operating with FREON-refrigerants.

Decades of experience with this energetically very convenient system made it highly reliable. However, these systems work with very high ammonia chargesvery high ammonia chargesvery high ammonia chargesvery high ammonia charges. Due to an increasing number of regulations and directives concerning the safety of industrial refrigeration plants, the reduction of the ammonia charge has become a more and more important issue. Besides the search for alternative refrigerants which are environmentally acceptable and energetically competitive to ammonia, several solutions dealing with the above mentioned problem of improving the safety by reducing the ammonia charge have been proposed during the last years: Spray Type evaporators – HANSA Type: TIWK-N ++++ high COP (small ∆T) ---- required space ++++ highest cooling capacitieshighest cooling capacitieshighest cooling capacitieshighest cooling capacities ++++ no danger of freezing ++++ easy mechanical cleaning ++++ no superheat of suction gas Fully welded Shell and Plate Type evaporator (flooded) HANSA Type: TIWK-AP ++++ highest COP highest COP highest COP highest COP (minimized ∆T) ---- no mechanical cleaning ++++ for small and high cooling cap. ++++ little required space ++++ no superheat of suction gas + lowest Ammonia charge+ lowest Ammonia charge+ lowest Ammonia charge+ lowest Ammonia charge + no gaskets to ambient = fully welded + reliable flooded system with separator + easy controllable The Concept: A tailormade system for your demand HIGH CAPACITY SHELL AND PLATE-TYPE EVAPORATORS WITH AMMONIA SEPARATOR • compact design the shell and plate type evaporator combines the energetically advantages of the flooded system with the high efficiency and low refrigerant charge of plate type heat exchangers. • range of capacity the AP-system is available from 100 kW to more than 2000 kW per unit. • variability all systems are available as packaged units or in split design. With evaporative, water-cooled or hybrid dry-cooled condensers • safety completely welded heat exchanger plates avoid problems known when using ammonia with soldered or sealed plate type heat exchangers. • low energy – highest COP due to the high pressure float valve control and no superheating of the suction gas, highest coefficients of performance are obtained. • simple operation the refrigeration system AP works with ammonia of standard quality (DIN 8960) and with standard mineral oils for lubrication. The System: SHELL AND PLATE - AP Total Reliability – The compressor, the heart of the chiller A range of outstandingly reliable open type, reciprocating refrigeration compressors, designed to work efficiently in almost any type of industrial refrigeration installation. These compressors are the result of an intensive R&D effort. Central to their design it is absolute reliability under the most demanding circumstances and with an alert eye to economics, that is a modest investment at low maintenance costs. This was achieved by incorporating innovations like composite material valves and lightweight pistons with low-wear piston rings into a design that has already proven itself in actual practice. Combined with the unique welded steel compressor concept, these innovative features enable us to offer you total reliability and maximum efficiency. The HANSA/Grasso HRC compressors are probably of the most modern design compressors available in the market of today. Welded Steel Crankcase The concept of a welded steel crankcase keeps the discharge temperatures low and eliminates the need for external oil and/or cylinder head cooling systems. This unique concept has proven itself in more than 50,000 compressors all over the world. Suction and Discharge Valve Combined composite material suction and discharge valves have been specially developed to ensure optimal performance and outstanding reliability. Suction Valve Lifting Hydraulic valve lifting mechanisms for the individual cylinders ensure optimal capacity control and for the compound compressors additional fast pull down capacities. Lubrication Fully integrated lubrication system prevents oil leakage, ensures effective internal cooling and a perfect oil supply to the compressor bearings. Piston/Connecting Rod assemblies and cylinder Liners The surface finish of the cylinder liners and the special piston rings ensures low wear and a long service life. Bearings High quality, low load radial and axial bearings with excellent sliding and running characteristics reduce wear to a minimum. Rotary Shaft Seal A virtually gastight, oil-cooled seal guarantees minimum leakage and a long service life.
