The GAHT system is essentially an air-to-ground heat exchanger, unable to deliver specific temperatures, but can assist with some heating and cooling. The GAHT can reduce overall peak loads and therefore operational costs.
The EcoLoop is a higher-tech, more robust mechanical HVAC system. It provides total cooling, heating, and dehumidification based on specific set points maintained by a Ceres’ Controller.
Considerations for choosing between the GAHT and Ecoloop are:
1. Environmental control precision: The Ecoloop can control environmental parameters within 5-7% of requirements. The GAHT is therefore a good option for vented greenhouses, whereas the EcoLoop is ideal for sealed grow environments.
2. Budget: The Ecoloop startup cost is around 2-3 times greater than the GAHT system.
