Brand Upgrade

The brand evolution signals our ambition to expand globally.

We’ve been known as Yangyi for years, a name rich with meaning but not the easiest to pronounce, making it tough for our partners to spread the word.

To help our network grow the business, we’re stepping up with a fresh, intuitive logo: COLINK. However, faced with registration hurdles, we’ve pivoted to adopt COOLINK as our go-to brand.

The new identity draws inspiration from the HVAC industry’s core. “COOL” reflects the industry’s key feature, while “LINK” captures our mission to forge strong connections with our team, customers, suppliers, and users.

We are a leading HVAC refrigeration vacuum pump manufacturer, established in China since 2007 and ranked among the top 3 globally. Our expertise spans innovative product development and reliable OEM solutions, backed by a strong focus on research and development.

Our MOQ policy is designed to support both new and established partners. For certain models, we accept small order quantities starting from just 10 pieces, facilitating our new partners to test the market with low risk and investment.

For regular orders, however, we require a minimum order value of USD 4,000 to cover fixed logistics and handling costs efficiently.

We provide a 12-month limited warranty for our distributors. This warranty becomes effective from the loading date as indicated on the Bills of Lading for sea shipments. For other delivery methods, the warranty period starts from the shipment date from our factory.

Absolutely, we offer OEM services to cater to your branding needs. However, for customizations like non-standard colors, personalized nameplates, tailored operating manuals, and specialized packaging, a higher order volume than our standard MOQ may be necessary to offset the additional costs involved.

Certainly, we understand the importance of sample evaluation and are happy to accommodate this request. We kindly ask you to cover the costs for the sample and freight. Additionally, the cost of the sample can be credited towards your future official orders. As a token of our support, we're also pleased to offer one complimentary sample for smaller models.

Our preferred payment method is via wire transfer (T/T). We require a 30% prepayment, with the remaining 70% due before shipment. Currently, we do not accept Western Union or PayPal as per our accounting department's policies. In specific cases, we may consider accepting an L/C (Letter of Credit) at sight, depending on the country of origin and the issuing bank.
