The System Process Flow Is As Follows:

The liquid refrigerant in the evaporator of the unit is exchanged with the circulating air in the interior of the tank. The temperature rises from liquid to gas, and is sucked into the suction port of the compressor. The high-temperature and high-pressure refrigerant gas after compression by the compressor passes through The oil separator separates the refrigerating machine oil carried in the compression process, and then enters the condenser, and exchanges heat with ambient air or cooling water to change from high temperature and high pressure gas to high pressure normal temperature liquid. The high-pressure normal temperature refrigerant liquid is dried by a filter and then throttled and depressurized by an expansion valve, that is, from a high-pressure liquid to a low-pressure liquid. The low-pressure liquid (lower boiling point) enters the evaporator of the unit, and the cooling air is brought to the inside of the tank through the circulating air to achieve refrigeration.

Product features and advantages:

The anti-freeze solution is injected into the 80L pressure vessel, and the fully closed circulation system is adopted. This avoids the opportunity for the antifreeze to contact with the outside air and ensures the condensation of the water. After the expansion tank is protected by nitrogen, the temperature range of the heat transfer liquid is also broadened because its boiling point is increased. In addition, oxidation of the thermally conductive liquid in contact with oxygen in the environment is also avoided, thereby extending the useful life of the thermally conductive liquid.

LNEYA attends various exhibitions at home and abroad every year. At the exhibition, we show the latest research equipment of LNEYA. Every year, long-term cooperative customers will come to exhibitions and communicate with us. We are also actively developing new customers to provide them with high quality machines and services.

After sale service

Quality assurance

Guarantee that the goods are sold to be conform to the provisions of the contract and qualified new products by factory inspection, quality performance, technical indicators and configured are in accordance with manufactures and technical documents stipulated in the contract.

Installation and debugging

After the arrival of the goods, my company or my company agent is responsible for installation and debugging of equipment need on-site installation and debugging.

Inspection and acceptance

After installation and debugging, acceptance by the customer to confirm the goods to be conform to the provisions of the contract and qualified new products, quality performance, technical indicators and configured are in accordance with manufactures and technical documents stipulated in the contract, and after the confirmation of a full set of technical documents, sign the installation acceptance report and confirm acceptance.


At the same time of installation and debugging of equipment, my company’s after-sales service engineer is responsible for technical training for user until user can be skilled of operation. In the process of using equipment by customer, customer can consult relevant technical issues to after-sales service personal of our company at any time, according to the situation, my company will arrange training on site or remote.

After sale service commitment

A full free one year warranty since the date of acceptance, during the warranty period, all repairs and spare parts are free of charge(instrukent malfunction caused bu human factors will be charged of cost price of spare parts); After the warranty period, we will be responsible for maintenance of equipment for lifetime, according to the actual maintenance fees, appropriate fee will be charged.

(PS:There will have extra charge if the customer need on-site service. And customers need to describe the issue first and then send some failed pics or videos in advance, then Lneya judge if it is possible to go for after-Sales on site. )
