With the development of HACo (Hygroscopic Adiabatic Cooling), a major, practical step has been made towards the cultivation of plants and crops in horticultural greenhouses in tropical climates. With this, we as a sector are better able to facilitate the growth of a worldwide horticulture industry. The main problem with humid climates is the extremely high-energy consumption required for condensing the moisture from the air, and it is the reuse of this latent energy that makes HACo so innovative. HACo has significantly broadened the range of climates in which ModulAIR (semi-closed) horticultural greenhouses can be deployed. Where HACo is added to the ModulAIR system, the interior climate can be treated and controlled with the precision of a semi-closed system, despite the higher air humidity and more challenging nature of the tropical environment. What’s more, the system runs predominantly on heat as energy, which allows energy sources such as biomass power plants to be used, with only a small amount of additional electrical power required for the other components.

HACo 93b2d

The unique character of HACo within the ModulAIR system manifests itself through:

  • an applicable solution for cultivation in tropical climates
  • the high degree of precision of control over the interior climate by the semi-closed system
  • optimal use of energy and CO2
  • the low energy consumption
  • the higher yields
  • minimal use of pesticides
  • sustainable production
