AGO Caldora
Industrial, large and high temperature heat pumps
Make waste heat or environmental heat efficient process or district heat.
Would you like renewable energy (e.g. from river or ground water, geothermal, air, waste water etc.) as Heat source for your Heat supply use?
Run large amounts of heat to the environment, e.g. Cold productionin the form of moist-warms Exhaust air flows or Process cooling?
Would you like CO2 emissions and Energy costs in your process heat supply reduce?
Yeah?
The AGO Caldora is an industrial heat pump which, in a large power and temperature range, brings extremely efficient low temperature heat to a higher usable temperature level.

How does an AGO Caldora heat pump work?
In a conventional heat pump, a refrigerant is evaporated at low pressure by absorbing heat from a heat source. The vapor-shaped refrigerant is then compressed from low pressure to high pressure with a refrigerant compressor.
At high pressure, the refrigerant condenses with heat output to a heating medium at high temperature. The refrigerant then liquefied is expanded again from high pressure to low pressure through an expansion valve for closing the thermodynamic circular process.
In the case of a heat pump with a solution circuit, such as the AGO Caldora, the heat exchanger for cooling the heat source is not called vaporizer but extractor. A solution of ammonia and water is heated in this heat exchanger. The light-boiling ammonia thereby partially evaporates, the water remaining liquid. In a subsequent separator, the two phases are separated.
As usual, a refrigerant compressor compresses the refrigerant vapor from low pressure to high pressure. Parallel to this, a solution pump pumps the solution, which is poor in ammonia, from low pressure to high pressure. Both currents are then conducted together into the absorber.
In this heat exchanger, the ammonia vapor dissolves again in the aqueous solution. This process is called absorption and is an exothermic process. The resulting heat is released to the heating medium. The solution again rich in ammonia is expanded from high pressure to low pressure in a throttle valve in order to close the circular process.
Advantages of AGO Caldora heat pump
We use ammonia/water solution as working medium. The following advantages result from this:
- Use of a natural refrigerant (GWP=0; ODP=0)
- The pressure level can be adjusted independently of the temperature levels of the heat source and heat sink by adjusting the ammonia concentration.
- Even at high heat sink temperatures, relatively low operating pressures are possible.
- High spread on the heat source and/or heat sink side significantly increases efficiency.
- In this case, the current requirement is significantly lower than in alternative heat pumps with single-substance refrigeration means.
- Use in a very large temperature range on the heat source and heat sink side.
- Compressors from renowned European manufacturers are used.
- All containers, heat exchangers and pipe fittings are made of stainless steel, ensuring long durability and reliability.
