Ningguo Kingcool Import and Export Co., Ltd supplies Refrigerant and a complete range of refrigeration and HVAC parts for wholesalers, contractors, service companies and equipment builders. Our refrigerant line covers R134a, R410A, R22, R404A, R407C and MAPP gas, supported by copper tube, filter drier, manifold gauge, vacuum pump and leak detector from the same warehouse. We combine in-house capacitor production with a broad trading range, so a single purchase order can cover the refrigerant charge, the electrical components and the service tools for a project.
Refrigerant Range and Where Each Product Fits
As a Refrigeration Parts-Refrigerant Manufacturers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
We stock refrigerant in disposable cylinders, refillable cylinders and large-capacity drums, with the cylinder size selected to match the charging method and the volume of the project. R134a is the standard choice for domestic refrigerators, water dispensers and automotive air conditioning. R410A and R32 serve residential and light commercial split systems, while R404A and R407C cover cold rooms, display cabinets and transport refrigeration. R22 remains available for servicing existing equipment in markets where it is still permitted.
MAPP gas and hand torch kits sit alongside the refrigerant range for brazing and soldering work. A service company can therefore order the refrigerant, the torch gas and the copper fittings in one shipment, which reduces freight cost and customs handling compared with separate purchases.
Refrigerant Grades and Packaging Options

| R410A | Residential and light commercial split systems | 11.3 kg / 25 lb | Disposable and refillable cylinders |
| R22 | Legacy A/C and refrigeration service | 13.6 kg / 30 lb | Disposable cylinders |
| R404A / R407C | Cold rooms, display cabinets, transport refrigeration | 10.9 kg / 24 lb | Disposable and refillable cylinders |
| MAPP gas | Brazing and soldering of copper pipe | 400 g hand torch cylinder | Cylinder with torch kit |
Materials, Purity and Cylinder Construction
Refrigerant purity directly affects compressor life and system efficiency. We supply refrigerant that meets the accepted industry purity level for the grade ordered, and each cylinder carries a batch identification so the charge can be traced back to the filling record. Cylinders are manufactured from steel with a protective coating, fitted with a valve that accepts standard charging hoses, and supplied with a safety cap for transport and storage.
- Purity: moisture and non-condensable gas controlled to protect the compressor and expansion device.
- Cylinder: steel body, coated finish, standard valve thread, safety cap.
- Labeling: product name, net weight, batch number and hazard markings on every cylinder.
- Compatibility: suitable for copper, brass and standard elastomer seals used in HVAC systems.
One-Stop Sourcing Across the Refrigeration Parts Range
Refrigerant is rarely ordered alone. A contractor replacing a compressor also needs a Compressor, a filter drier, a contactor and a capacitor. We hold these items in the same catalogue, so the refrigerant, the electrical parts and the copper fittings can be consolidated into one shipment. This is the practical value of our one-stop model: fewer suppliers, fewer documents and a single delivery schedule.
Our in-house production of metalized polypropylene film capacitors supports the electrical side of the same order. Capacitors are wound, impregnated and tested on our own lines, which gives us direct control over the component that most often fails in a running air conditioning system.
Related Categories We Supply
- Refrigeration Parts — copper tube, filter drier, oil separator, manifold gauge, vacuum pump and leak detector.
- Capacitor — CBB65 motor run capacitors produced on our own slitting and winding lines.
- Refrigerator Parts — capillary tube, thermostat, filter drier and control board for domestic refrigeration.
Charging, Recovery and Service Tools
A refrigerant order is only complete when the service team can charge, recover and verify the system. We supply the supporting tools from the same range: manifold gauge sets, vacuum pumps, refrigerant recovery units, charging scales, thermometers and electronic leak detectors. These items are selected to match the refrigerant type and the working pressure of the system, so a technician is not mixing R410A gauges with an R134a charge.
For brazing work, the MAPP gas cylinder and hand torch kit provide a portable heat source for copper joints. We also supply copper tube, brass fittings and insulation tube so the pipework can be completed in the same delivery.
Quality Control and Documentation
Every cylinder is checked for weight, valve tightness and label accuracy before packing. Refrigerant is filled under controlled conditions and the batch record is retained so that a specific cylinder can be traced if a question arises. For capacitors, our testing equipment monitors production in real time, and finished units are checked before they enter the warehouse.
Shipping documents are prepared to match the destination market. Depending on the product and the country, this includes the commercial invoice, packing list, certificate of analysis for the refrigerant batch and the safety data sheet. Cylinders are packed in cartons or on pallets with edge protection, and the outer packaging carries the handling marks required for pressurized gas.
Information We Use to Configure Your Solution
To quote accurately and avoid a wrong shipment, we need the following project inputs. The more precisely these are stated, the faster we can confirm the cylinder size, the packing and the delivery schedule.
| Input | Why We Need It |
|---|---|
| Refrigerant grade and quantity | Determines the product, cylinder size and total weight for freight. |
| Cylinder type | Disposable or refillable changes the packing and the return policy. |
| Destination port and market | Affects labeling, documents and the applicable import requirements. |
| Associated parts list | Lets us consolidate refrigerant, tools and spare parts in one shipment. |
| Annual or project volume | Supports production planning and a stable supply schedule. |
Storage, Handling and Service Support
Refrigerant cylinders should be stored upright in a dry, ventilated area away from direct sunlight and heat sources, with the valve cap in place. We recommend that stock is rotated so the oldest batch is used first, and that cylinders are never dropped or used as a support. For service teams, we can supply the matching gauge set, recovery unit and leak detector so the same refrigerant is charged and recovered with compatible equipment.
Spare parts for the tools we supply, including gauge hoses, valve cores and torch nozzles, are available from the same catalogue. When a customer runs a service business, we can build a repeat order list that covers the refrigerant, the consumables and the common electrical spares, so restocking is a single transaction.
Frequently Asked Questions
Which refrigerant grades does Kingcool supply?
We supply R134a, R410A, R22, R404A, R407C and MAPP gas, together with the cylinders, gauges, vacuum pumps and leak detectors needed to charge and service a system. The grade is matched to the equipment and the market where it will be used.
Can I combine refrigerant with other refrigeration parts in one order?
Yes. Refrigerant, copper tube, filter drier, manifold gauge, capacitor and compressor can be consolidated into one shipment. This is the core of our one-stop supply model and it reduces freight and customs handling for the customer.
What cylinder sizes are available?
Common sizes include 13.6 kg and 11.3 kg disposable cylinders, smaller hand torch cylinders for MAPP gas, and refillable cylinders for larger service operations. The size is confirmed against the charging method and the order volume.
What documents come with a refrigerant shipment?
Shipments are prepared with a commercial invoice, packing list, batch certificate of analysis and safety data sheet, with labeling adjusted to the destination market. The batch number on each cylinder allows the filling record to be traced.
Do you supply the tools needed to charge and recover refrigerant?
We supply manifold gauge sets, vacuum pumps, recovery units, charging scales, thermometers and electronic leak detectors, selected to match the refrigerant type and system pressure. Consumables such as hoses, valve cores and torch nozzles are available as repeat items.
