Reduce energy costs. Control demand peaks. Increase your independence.
SISTEA integrates energy efficiency, industrial air conditioning, refrigeration, ventilation, electrical energy management, on-site generation, storage, circular economy solutions, and financing into one project.
We first reduce consumption, losses, and demand peaks. We then integrate only the technologies required to cover the remaining energy demand efficiently, profitably, and sustainably.

The financial value for your company
Lower costs. Fewer demand peaks. Greater control over your energy.
Where is your company currently losing money through consumption, inefficiency, or energy dependence?
We do not start by selling equipment. We first identify where energy and money are being lost, when demand peaks occur, and which measures offer the strongest economic return.
Avoid demand peaks
Detect rising loads, sequence equipment, shift noncritical demand, and use batteries when it creates value.
Use waste heat
Production heat can support absorption cooling, hot water, drying, or preheating.
Increase self-consumption
Coordinate photovoltaics, batteries, production, and the grid to buy less electricity and increase energy independence.
Measure and verify savings
Compare baseline, current consumption, production, weather, on-site generation, and avoided costs to demonstrate results.
Finance through savings
Depending on the project, energy savings can cover a significant share of investment and financing costs.
The SISTEA system
Five modules. One integrated system. One economic objective.
SISTEA does not sell isolated solutions. We design every project as a complete technical and financial system. We first identify where energy is consumed, lost, or unnecessarily paid for. We then combine the right technologies to reduce costs, manage demand, and increase energy independence.
Financing connects the entire system
Financing is not a separate technical module. It sits above the entire project. Depending on the structure, energy savings can cover a significant share of investment and financing costs.
Consulting, analysis, and planning
Technical and economic assessment, energy audits, load profiles, production processes, feasibility, engineering, return analysis, and financing structure.
Energy efficiency and electrical management
Real-time control, savings-potential identification, peak reduction, load management, power quality, and results verification.
Air conditioning, refrigeration, ventilation, and heat
Industrial HVAC, process cooling, ventilation, dehumidification, two-stage adiabatic systems, heat recovery, and absorption cooling.
On-site generation, storage, and circular economy
Photovoltaics, batteries, solar thermal, cogeneration, waste-heat recovery, and ECOLOOP as a modular gasification technology.
Integration, installation, monitoring, and maintenance
Project management, supply, installation, electrical and plumbing work, commissioning, monitoring, preventive maintenance, and continuous optimization.
Technologies selected for each project
Technologies that reduce demand, recover energy, and supply the remaining load.
Each technology must serve a clear role in the system and create measurable technical and financial value.
Two-stage adiabatic air conditioning
Large air volumes and reduced supply-air temperatures with far lower electrical consumption than conventional solutions in suitable applications.
New indirect adiabatic generation
A planned world-first innovation expected from Q3 or Q4 2026: fully indirect cooling without directly adding moisture to supply air, designed for lower temperatures, larger airflow, and reduced humidity.
Absorption cooling
Cooling produced with free waste heat, hot water, steam, exhaust heat, solar thermal energy, cogeneration, or ECOLOOP heat.
Industrial and process refrigeration
Cold rooms, chilled water, food preservation, production processes, heat recovery, and modernization of existing systems.
Ventilation, dehumidification, and air drying
Airflow, temperature, humidity, filtration, and pressure matched to actual process conditions.
Electrical management and peak shaving
Monitoring of consumption, peak demand, critical loads, motors, photovoltaics, batteries, power factor, and deviations.
Photovoltaics and batteries
Higher self-consumption, reduced grid purchases, peak shaving, backup capability, and improved operational stability.
Solar thermal and heat recovery
Hot water, preheating, drying, thermal processes, and energy input for absorption systems.
ECOLOOP and circular economy
Conversion of technically suitable carbon-based residues into syngas for process heat, electricity, cogeneration, and partial fossil-fuel substitution.
MIG coatings
Interior and exterior coatings designed to reduce thermal loads on roofs, façades, and production areas.
Water treatment and management
Filtration, conditioning, reuse, equipment protection, and reduced water consumption.
The least expensive energy is the energy that is not consumed, is recovered, or is reused.
Technologies and applications
There is no single solution. There is a right combination.
We select and integrate technologies based on the process, climate, humidity, available resources, and expected economic return.
Electrical energy management and peak control
We measure, prioritize, and control loads to reduce consumption, demand peaks, and capacity charges.

Structured financing and ESI
Technology must create savings. Savings should support the investment.
SISTEA integrates technical planning with an appropriate financing structure. The assessment determines consumption, costs, peaks, losses, savings potential, investment, return, and cash flow. Depending on the project, savings can cover a significant share of investment and financing costs.
ESI insurance does not replace the provider’s technical responsibility and is not an automatic financing approval.
