How does the liquid injection technique work?

Liquid injection helps prevent the compressor from overheating, maintaining performance under high-load operating conditions

What test conditions apply to capacity ratings?

esting is conducted under standard commercial refrigeration conditions (e.g., Condition C/D for evaporating and condensing temperatures)

AI-Powered supplier vetting

SummaryThe supplier is identified as a manufacturing factory in Lanxi, Jinhua, with production-related facilities including assembly, production, cylinder, and electrophoresis lines. It provides 3D software design, ODM, OEM for well-known brands, SDK support, and multiple customization modes. Quality processes include written inspection instructions, quality assurance, complaint-handling procedures, raw-material traceability, and documented supplier-management procedures. ISO 9001:2015 and ISO 45001:2018 certificates are reported. Overseas support offerings include debugging, maintenance, repair, training, and equipment installation, but the supplier reports no overseas warehouses, showrooms, agents, branches, or offline trade-show participation. Financial records are identified for 2020–2022, but no evaluative financial results are provided. No new products were reported in the past year, and no customer-specific cases are disclosed.

Supplier typeThe supplier is explicitly classified as a factory, located in Lanxi District, Jinhua City, and associated with the manufacturing industry. This supports classification as a manufacturing supplier rather than a trading or service-only company.

CertificationsThe supplier reports ISO 9001:2015 and ISO 45001:2018 certificates, indicating documented quality-management and occupational-health-and-safety certifications. However, the same slice states that no factory environmental impact assessment report is available, so environmental documentation is incomplete.

After-Sales capabilityThe supplier has a clear, recorded customer-complaint procedure and offers debugging, maintenance, repair, training, and equipment installation. However, it reports zero countries with overseas service offerings and no overseas warehouses, showrooms, agents, or branches, indicating service capability exists but is not supported by an established overseas network.

R&D capabilityThe supplier provides 3D software design, ODM services, OEM services for well-known brands, and an available SDK, demonstrating stated design and development capabilities. However, it also reports no new products in the past year, so recent innovation output is not demonstrated.

Production capacityThe supplier reports assembly, production, cylinder, and electrophoresis lines, finished-product inspection instructions that are uniformly followed, quality assurance, complaint procedures, and traceability for raw materials. These documented facilities and controls support production capability, although no production volume or capacity figures are provided.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, along with 3D software design services. The repeated evidence across the service and production records supports broad customization capability.

Product Q&A

Q:What is the main application of the KHSP203Z312 compressor?

It is widely used in commercial refrigeration equipment, such as horizontal display cases, food retail cabinets, and space-constrained cold chain units

Q:What refrigerant does KHSP203Z312 use

It is optimized for R290 eco-friendly natural refrigerant

Q:What power supply does KHSP203Z312 require?

It operates on a DC 312V power supply (DC Inverter) AND AC220V

Q:Why choose a horizontal design compressor?

The low-profile horizontal design maximizes internal storage space in refrigerated display cases where height is limited

Q:What are the benefits of the twin rotary structure

twin rotary design distributes compression torque evenly, significantly reducing vibration and operational noise
