View solution →SISTEA system
Five modules operating as one system
The architecture combines humidity control, efficient cooling, renewable energy, intelligent controls and thermal protection of the building envelope.
Dehumidification
Precise humidity control protects processes, products, buildings and comfort.
Two-stage adiabatic cooling
Supply-air temperatures below wet-bulb temperature without adding moisture to the supply air.
Solar and batteries
Renewable generation, demand reduction and backup for critical loads.
Intelligent control
German data-driven technology coordinates all modules and optimizes operation.
MIG coatings
Interior and exterior thermal-load reduction improves efficiency and indoor climate.
Method
From baseline to verified operation
We do not start with equipment. We start with data, operational goals and real constraints.
01 · Assessment
Consumption, climate, loads, processes, air quality, water and infrastructure.
02 · Feasibility
Concept, sizing, CAPEX, OPEX, savings, risks and return.
03 · Delivery
Engineering, procurement, logistics, installation, coordination and commissioning.
04 · Follow-up
Measurement, control, maintenance, optimization and result documentation.

Frequently asked questions
Information for an initial decision
Direct answers on scope, process and financing.
Where does SISTEA work?
SISTEA is based in El Salvador and develops projects across Central America according to technical scope, logistics and regulatory requirements.
Does SISTEA sell equipment or deliver complete projects?
Both. We supply specific equipment and can also assume engineering, planning, installation, commissioning, project management and follow-up.
How does an assessment begin?
With basic consumption, operation, location, goals and constraint data. We then define the site survey, baseline, feasibility and technical concept.
Can a project be financed through savings?
Suitable projects can use ESI and other financing structures. Feasibility depends on verifiable savings, guarantees, counterparties and documentation.
Does SISTEA work with specific technology?
We select European technology for the application. Performance, efficiency, maintainability and local conditions drive the solution, not an isolated brand.
