Engineering + Supply | District Heating
District Heating Substation — 5 MW
System design, heat exchanger selection, hydraulic calculations, and equipment supply for a modernization project.
Thermal & Energy Systems Engineering
From system concept and calculations to equipment selection, integration, and commissioning — a single team for thermal and energy infrastructure across the Baltics.
Two paths, one engineering team
We define the system before selecting the equipment. Whether you need engineering support, equipment supply, or both — the approach is always system-level, not component-level.
Engineering & System Design
System concept, hydraulic calculations, equipment specification, integration into existing infrastructure. For decision-makers who need engineering before procurement.
Engineering-Driven Equipment Supply
We supply equipment as part of a system — not as isolated components. Every order includes technical specification review and compatibility verification.
Engineering-first approach
We approach every project at the system level. Performance optimization (ΔT, efficiency, load profiles), risk reduction during design, and integration into existing infrastructure are standard — not optional add-ons.
System-level thinking
We analyse the complete thermal system — sources, networks, consumers — before sizing individual components. The equipment serves the system, not the other way around.
Infrastructure integration
New equipment must work with what already exists. We design for integration into existing district heating networks, CHP plants, and industrial processes.
Performance optimization
ΔT optimization, load profile analysis, efficiency calculations. We quantify improvements before recommending changes.
Risk reduction
Independent technical review, specification compliance verification, commissioning support. We reduce risk during design and implementation phases.
