How can I control the compressor speed?

There are 4 ways: Potentiometer (included), 0-5V, PWM, and TTL communication port. Potentiometer is the most common method.

Does the unit include refrigerant and thermostat?

The unit is filled with refrigerant and oil before shipping. It is a sub-system without an On/Off switch, so you need to wire up your own switch.

What are the payment and shipping terms?

Payment via PayPal, Credit cards, Bank transfer, or L/C. Shipping via DHL/UPS, Air, or Sea. Terms: 50% deposit in advance, balance against B/L or courier receipt.

What is the warranty policy?

We provide a one-year warranty and lifelong technical support for our products.

Can I return the unit if it has quality defects?

Yes, we will provide a 100% refund if the purchase has any quality defects.

AI-Powered supplier vetting

SummaryThe supplier is a limited trading company with eight employees, focused on miniature refrigeration and thermal-management products, including miniature compressors, DC air conditioning, compact liquid chillers, and free-piston Stirling coolers. It holds a valid import and export license, exports approximately 90% of sales, and serves domestic, East Asian, European, and North American markets. Stated production volumes are substantial across several product categories, but the supplier’s organizational scale and service infrastructure appear limited. It offers flexible customization but does not provide SDKs, ODM services, or OEM services for popular brands, and reports no new products in the past year. Service procedures exist for corrective actions and customer complaints, but written records are unavailable; no overseas service countries are identified. Financial data is only represented by years, without financial performance figures, so credibility cannot be assessed. No certifications or customer...

Supplier typeThe supplier is identified as a trading company and a limited company, with no larger corporate-group affiliation. It has eight employees and a valid import and export license, indicating a legally registered, independently operated trading entity rather than a stated manufacturing-group subsidiary.

After-Sales capabilityThe supplier has procedures for corrective and preventive actions and customer complaints, but no written records are maintained. It reports zero countries offering overseas services and only one qualified service-capability supplier, indicating limited documented and international after-sales support.

R&D capabilityThe supplier describes itself as a miniature compressor innovation leader and offers flexible customization, but it has no available SDK, reports no new products in the past year, and does not provide ODM services. The evidence supports product-domain positioning but not strong current innovation output or development infrastructure.

Production capacityThe supplier offers multiple refrigeration products and reports annual outputs of 50,000 condensing units, 30,000 free-piston Stirling cryocoolers, 50,000 custom cooling systems, 50,000 compact liquid chillers, and 100,000 DC compressors. These stated volumes indicate established supply capability, although the company has only eight employees and is classified as a trading company, so the underlying production ownership is not clarified.

Customization capabilityThe supplier explicitly provides flexible customization and lists custom cooling systems among its offerings. However, it does not provide ODM services, so customization is supported but does not extend to the stated ODM model.

Product Q&A

Q:What is a Coaxial Liquid Chiller?

It uses a stainless steel coaxial tube heat exchanger to transfer heat between two fluids, offering extraordinary cooling performance as fluids spread over liquid tubes.

Q:What are the main applications?

It is compact and lightweight, suitable for personal cooling (racing drivers, outdoor workers), laser devices, medical/aesthetic equipment, and precise electronic cooling.

Q:What materials is it made of?

It consists of a high-efficient refrigeration mini compressor, controller, condenser, evaporator, filter drier, refrigerant, and other parts, all integrated into one unit.

Q:Can I connect software to control the chiller?

Yes, the customer's software can connect with the driver board to control compressor speed and access complex functions needed for system integration.

Q:What are the advantages of this compact chiller?

Advantages include low vibration/noise, extreme portability, precise temperature control, high capacity relative to size, and high reliability with less maintenance.
