Geometry
P&ID, CAD or isometric drawing; a legible hand sketch is enough to start.
OEM / ODM engineering
Custom manifolds, skids and welded sub-assemblies built from your CAD package and acceptance criteria - from a single engineering sample to batch production.

What to send
The more of this you can share up front, the faster the manufacturability review comes back.
P&ID, CAD or isometric drawing; a legible hand sketch is enough to start.
Coolant type, flow rate, temperature and pressure range.
Connection types, port positions, pitch and mating part specifications.
Preferred grade, internal roughness requirement, passivation or cleaning needs.
Target quantity, sample requirement, destination market and required delivery date.
Leak-rate criterion, pressure test value, documentation and inspection requirements.
Engagement
No fixed finished-system SKUs. Every project is quoted against its own drawing.
Next step
Include coolant, flow rate, sizes, material and target quantity.
