How do I start the machine correctly?

Follow the sequence: Connect power, close circuit breaker, click Power, turn on cycle switch, turn on refrigeration switch, and finally turn on the cold storage device.

What should I do if there is a leak in the pipeline?

Apply soapy water to the copper pipe welds to check for bubbles. If found, repair by professionals, refill with the correct refrigerant, and restart.

Is the product customizable?

Yes, customization from samples is available.

AI-Powered supplier vetting

SummaryHenan Lanphan Industry Co., Ltd. is identified as a trading company engaged in import/export, technology research and development, and laboratory instrument production. It has 11 years of export experience, with exports representing 71%–90% of total sales, and states that it can provide customization from samples. However, the supplier reports no management-system certification, no written procedures or records for corrective actions, complaint handling, or service-capability assessment, and no overseas showroom, agents, branches, or offline trade-show participation. R&D evidence is limited: three years of total R&D engineer experience, no new products in the past year, no ODM, no SDK, and no 3D software design service. Quality controls include quality assurance, random finished-product inspection, and one QA/QC inspector, but raw-material traceability is absent and finished products are checked by packing staff. No customer cases or named brand OEM evidence is provided.

CertificationsThe supplier management-system certification status is explicitly recorded as NIL. No certification is evidenced in the provided information.

After-Sales capabilityThe supplier has no written procedures or records for customer complaints, corrective and preventive actions, or effective service-capability assessment. It also reports no overseas showroom, overseas agents or branches, and no countries with overseas services, although it accepts multiple service quotation and payment terms and states a lead time within 15 workdays in both peak and off-season.

R&D capabilityInnovation evidence is limited to three years of total R&D engineer experience. The supplier reports no available SDK, no ODM service, no 3D software design service, and no new products launched during the past year, indicating explicit weaknesses in documented product innovation capability.

Customization capabilityThe supplier explicitly offers customization from samples, which demonstrates a sample-based customization capability. It does not provide ODM or 3D software design services, so the evidence supports limited customization rather than comprehensive design development.

Product Q&A

Q:What refrigerant is required for this pump?

You must use ethanol solution with a concentration of at least 97%. Do not use automobile antifreeze as it will damage the circulating pump.

Q:How do I check if the compressor has a fluorine deficiency?

When the pump is stopped at room temperature, if the pressure gauge value is less than 6 MPa, it indicates a fluorine deficiency. The value must be at least 0.2 MPa to prevent damage.

Q:What is the normal pressure gauge reading at room temperature?

For a single compressor, it should be 0.8-0.9 MPa. For a dual compressor, the first stage should be 0.8-0.9 MPa and the second stage 1.4-1.9 MPa.

Q:How should I clean the condenser?

Clean the condenser at least once a week to prevent clogging, which can cause heat buildup and compressor burnout.

Q:What are the precautions for placing the equipment?

Place the equipment in a dry, ventilated area with no obstacles within 500mm around the instrument.
