Services
Industrial Heat Exchangers
Custom-designed heat exchangers for industrial applications, including spiral fin and plate fin models. Built for durability in harsh environments, these units ensure efficient thermal energy transfer across sectors like nuclear and chemical processing. Our proprietary software optimizes performance for fluids ranging from steam to thermal oils.
Waste Heat Recovery
Systems to capture and reuse waste heat from flue gases, steam condensate, and industrial processes. Solutions reduce fuel consumption by 12-16% and CO2 emissions, incorporating economizers, recuperators, and run-around coils tailored to client operational cycles and contamination levels.
Process Drying
Steam, thermal oil, and hot water air heater coils for drying applications in food processing, textiles, and aggregates. Modular designs allow easy maintenance, with materials selected for temperatures up to 300C and pressures up to 20 bar, ensuring reliability in continuous operations.
Chillers
High-performance chillers for sub-ambient temperature control, available in mono/multi-scroll configurations. Utilizing low-GWP refrigerants like R454b and propane, these units serve data centers, manufacturing plants, and HVAC systems with capacities from 19kW to 2,500kW.
Flue Gas Analysis
Comprehensive analysis of exhaust gas composition to optimize heat recovery and reduce emissions. Measurements include temperature, O2, CO2, and NOx levels, enabling tailored retrofit solutions for boilers, dryers, and thermal oxidizers to enhance energy efficiency.
