Refrigerant and lubricant compatibility
HEAT-PUMP & HEAT-RECOVERY CASTINGS
Heat-pump compressor castings for project-specific duty.
Drawing review for compressor housings, scroll castings, bearing seats, cylinders and covers used in heat-pump and industrial heat-recovery equipment.
Custom castings around the heat-pump compressor
Anxin reviews drawings for iron components used around heat-pump and industrial heat-recovery compressors. We supply cast and machined components, not complete heat pumps or compressor packages.
Refrigerant, pressure, temperature, thermal cycling, fatigue, sealing and regulatory requirements must be defined for each project.

Material standard, NDT, traceability and annual volume
Manufacturing basis at Anxin
Anxin's existing compressor portfolio includes housings, cylinders, covers, scroll castings, suction and discharge components and bearing-related iron castings.
Iron-mold coated sand, shell molding and resin sand provide alternative routes for geometry and volume. HT250, HT300, QT450-10 and QT500-7 are reference candidates; the project drawing and standard govern the final material.
High-pressure refrigerants such as CO₂ are not accepted by a blanket statement. Design pressure, applicable code, material properties, validation and test scope require specific review.

What to include in the RFQ
Complete inputs make it easier to define the process, inspection scope and quotation boundary.
- 01Drawing, 3D model and compressor function
- 02Refrigerant, lubricant and operating envelope
- 03Design pressure, temperature and applicable code
- 04Fatigue or thermal-cycle requirement
- 05Leak-test, NDT and material-certificate requirements
- 06Machined delivery condition, forecast and sample plan
Clarify the application boundary first.
Does Anxin manufacture complete heat pumps?
No. Anxin supplies drawing-based iron castings and machined components for equipment manufacturers. Compressor design, refrigeration circuits, controls and complete-unit certification are outside this scope.
Can Anxin review parts for CO₂ refrigerant service?
Yes, drawings can be submitted for a specific review. No pressure range or suitability is assumed: the customer must state the refrigerant condition, design pressure, applicable code, material properties and validation plan.
Can pressure-containing compressor castings be reviewed?
Yes. Provide the pressure boundary, minimum wall, casting category, test method, acceptance limit, NDT and regulatory requirements so the technical team can determine feasibility.
What delivery scope is available?
Projects may be reviewed for as-cast, rough-machined or finish-machined delivery. Coating, testing, documentation and packaging are agreed separately against the drawing and acceptance criteria.
