Top Industrial Refrigeration Package Manufacturers in China (2026 Buyer's Guide)
By Qiangbin Chu · Sales Manager & Operations Lead, Suzhou Lmart Energy Equipment
Key Takeaways
- This guide clarifies component (compressor brand) vs package (skid integrator) and profiles both — from GEA/Bitzer/Mayekawa/Copeland/Danfoss to Chinese packagers.
- You specify the compressor brand; a packager integrates it into a certified, code-stamped refrigeration skid.
- Refrigerant drives the design — ammonia (IIAR-aware), hydrocarbons (ATEX zoning), and CO2 (elevated design pressures).
- Verify in-house code-compliant vessels and heat exchangers plus a complete data book — the paper is half the deliverable.
Quick answer: For industrial and process refrigeration, you actually buy from two different kinds of supplier. A compressor manufacturer (GEA, Bitzer, Mayekawa, Copeland, Danfoss) makes the core machine; a refrigeration package/skid integrator engineers that compressor into a complete, code-compliant system with pressure vessels, heat exchangers, piping, and controls. In China the leading package/skid partners include Lmart (Suzhou Lmart Energy Equipment), Hope Deepblue, Thermojinn, GUANFENG, Dalian Bingshan, and Yantai Moon. Choose on system-engineering depth, in-house code-compliant vessels/HEX, refrigerant expertise (NH3 / propane / CO2), and documentation — not on compressor branding alone.
Component vs. Package: The Distinction That Decides Your RFQ
Most confusion in industrial refrigeration procurement comes from treating "manufacturer" as one category. It isn't.
- The compressor manufacturer designs and builds the reciprocating or screw compressor — the beating heart of the cycle. These are global brands with decades of R&D behind bearings, rotor profiles, and control maps.
- The package/skid integrator takes the specified compressor and turns it into a system: mounting it on a structural skid, adding the separators, receivers, oil management, condensers/chillers, heat exchangers, refrigerant piping, valve trains, instrumentation, and PLC controls — then certifying the pressure-bearing envelope to the codes your project demands.
An EPC contractor or plant owner rarely needs "a compressor." You need a refrigeration duty met safely, on a skid you can drop into a process plant, LNG facility, cold-storage hub, or marine module. That is a packaging and pressure-equipment problem as much as a machinery problem — which is exactly why the integrator you pick matters.
Lmart sits squarely on the packaging side. Lmart does not manufacture refrigeration compressors — it specifies proven compressor brands (screw or reciprocating, e.g. Bitzer / GEA / Fusheng class machines depending on duty) and engineers them into complete, code-stamped refrigeration packages. Its edge is that the vessels, heat exchangers, and skid all come from one ASME/PED-qualified shop.
How to Choose an Industrial Refrigeration Package Maker
Use these criteria to score any shortlisted supplier:
- System engineering capability. Can they own the thermodynamic design — load calc, refrigerant charge, cycle configuration (single-stage, two-stage, economized, cascade) — not just bolt parts together? Ask for P&IDs and heat-and-mass balance, not a brochure.
- Code-compliant vessels and heat exchangers in-house. Separators, receivers, intercoolers, oil pots, evaporators, and condensers are all pressure equipment. A packager who fabricates these under its own ASME "U-Stamp" and PED (CE) authorization controls quality, schedule, and traceability. Outsourced vessels add risk at every interface.
- Refrigerant expertise across NH3 / propane / CO2. Ammonia demands IIAR-aware detailing and material compatibility; hydrocarbon (propane/R290) demands ATEX/zoning discipline; transcritical CO2 demands high-pressure design margins. A serious integrator designs to the intent of EN 378 (refrigerating systems safety) and, for ammonia, IIAR practice — as design context layered on top of the vessel code.
- Skid integration and controls. Structural skid design, vibration and pipe-stress management, valve trains, safety relief, gas detection, and a PLC/SCADA control philosophy that your operators can actually run.
- Documentation and certification package. Full data books: material certs (EN 10204 3.1), NDE reports, PWHT records, hydro/pneumatic test reports, U-1/U-2 forms, PED conformity, and as-built drawings. Weak documentation is the single most common cause of site-acceptance delays.

Frequently Asked Questions
Q1. Compressor manufacturer vs. refrigeration packager — what's the difference?
A compressor manufacturer makes the machine that compresses the refrigerant vapour. A refrigeration packager (integrator) engineers that compressor into a complete system — vessels, heat exchangers, piping, safety devices, controls — mounted on a skid and certified as pressure equipment. Most EPC and plant buyers are buying a *system*, so the packager's engineering and code capability often matters more than the compressor logo.
Q2. Who certifies an ammonia (NH3) refrigeration skid?
Certification splits by scope. The **pressure-bearing components** (separators, receivers, evaporators, condensers, piping) are certified to a pressure code — **ASME VIII (U-Stamp)** or **PED 2014/68/EU (CE)** in Europe — by an authorized manufacturer and verified by an Authorized Inspector or Notified Body. The **overall system safety** is designed to the intent of **EN 378** and, for ammonia specifically, **IIAR** standards. A qualified integrator like Lmart holds the ASME/PED authorization for the vessels and builds the system to those refrigeration-safety standards.
Q3. Can a Chinese packager integrate a European compressor brand (GEA, Bitzer)?
Yes — this is standard practice and often the preferred route. You specify the compressor brand; the integrator procures it and engineers the certified skid around it. Lmart is brand-neutral on the compressor precisely so buyers keep their preferred machine while gaining in-house ASME/PED vessel and skid fabrication.
Q4. Why does in-house vessel and heat-exchanger fabrication matter for a refrigeration skid?
Separators, receivers, intercoolers, and evaporators/condensers are pressure vessels and pressure-containing heat exchangers. When one shop designs, fabricates, and stamps them under its own code authorization — instead of subcontracting — you get tighter quality control, a single traceable data book, fewer interface disputes, and a shorter, more reliable schedule. It's the core reason to choose an engineering-led integrator over a pure assembler.
Q5. Which refrigerants can these packages use, and what changes per refrigerant?
Industrial packages commonly run **ammonia (NH3/R717)**, **propane (R290)** and other hydrocarbons, or **CO2 (R744)**. Ammonia needs material compatibility and IIAR-aware detailing; hydrocarbons need explosion-zoning (ATEX) discipline; CO2 — especially transcritical — needs elevated design-pressure margins. A capable integrator adjusts vessel design pressure, materials, relief sizing, and gas detection to the chosen refrigerant. ---
