Overview
Simultaneous development means joining the heat exchanger while the customer's new equipment is still being designed, rather than waiting for a frozen drawing. The benefit is that the coil can be optimised together with the machine structure, duct and control strategy. If the heat exchanger is left until the end, the remaining space and parameter window are usually too narrow, and both performance and reliability suffer.
Development process
From requirements to series supply, we work through five stages with defined outputs and confirmation points.
Requirements
Medium, temperature, flow, pressure and installation envelope
Design and calculation
Surface area, circuit arrangement, pressure drop and material selection
Prototype build
Sample built to the actual equipment structure to confirm fit and interfaces
Validation
Performance and reliability testing with the customer
Series supply
Frozen process and inspection for batch-to-batch consistency
Capability
The technical team carries out the thermal calculation and structural design and works directly with fabrication and inspection.
- Thermal calculation and selection: surface area, circuit layout and pressure drop
- Structure and interface design: internal space, duct and pipe routing
- Material selection against corrosion and medium compatibility
- Fin processes: high-frequency welding, brazing, tube expansion, embedding and winding
- Inspection and validation: incoming material, welding procedure, hydrostatic and leak tests
Proven applications
The following areas have moved from joint development to series supply or validation.
- PV cell manufacturing equipment: cold plates and fin coils in series supply
- Washing and drying equipment: steam heating coils in series supply
- Hydrogen equipment: vehicle recuperator, hydrogen generator heat exchanger and marine exhaust-to-oil unit
- Export: high-pressure steam heaters to Russia and a shell and tube unit to Italy
Ways to work together
- Prototype development: sample units and technical support for equipment under validation
- Joint development: participate in the customer's design process and agree the thermal and mechanical concept together
- Series supply: stable supply to the approved technical state with batch consistency
