-40°C Cooling from waste heat

Economic conditions for industrial and agricultural cooling energy generation have changed considerably over the past years. As electricity tariffs are rising constantly but heat is available from decentralized power generation, absorption chillers which use heat instead of electricity, in many cases may economically be more favorable than conventional reciprocating compression chillers.

The ammonia/water absorption chiller named “ago congelo” generates cooling energy up to a coolant outlet temperature of -40 °C. For this, the chiller primarily requires heat which is generated during the client’s industrial processes or during a CHP plant’s or gas turbine’s power generation. Compared to reciprocating compression chillers, this system’s electricity demand is only marginal.

Solutions to reduce costs and additionally save the environment

• Reduction of operating costs by using waste heat of the CHP
• Reduction of electric power input
• Low maintenance and repair costs
• Long durability, high reliability
• An increase of energy efficiency through trigeneration compared to a separate cooling generation
• Use of a natural refrigerant with long-term availability
• No chemicals are added (just pure ammonia and distilled water)
• Subsidised by Government
