Its current annual production capacity goes up to 300,000 pcs with a 26K square meters production space and 3 production lines. About 80% of its production is for overseas market. In Dellcool, more than 20 experienced engineers focus on the development and quality assurance of the specialty refrigerators.
Dellcool Company has 7 refrigeration product ranges, more than 100 models, covering absorption minibars , absorption RV refrigerators, free-standing gas refrigerators/freezers; compressor minibars, compressor RV refrigerators, compressor drink coolers and thermoelectric refrigerators.
With its know-how and quality and the support from all its partners, Dellcool refrigeration products have been shipped to more than 80 countries, including USA, Canada, Australia, EU, South East Asia and Africa . Among the partners, we are proud to have the experiences of working with big companies like Coca-Cola, Electrolux, some world-class hotel chains and big RV manufacturers.
Dellcool Company is dedicated to becoming a professional player in absorption refrigeration utilizing its engineering sources and quality product. Dellcool engineers focus on development of commercial specialty refrigerators with environment friendly green technology. The core value of the Company is“Quality First. Contributing value to Customers”.
After the strategic restructuring, Dellcool will stay more focused, making constant improvement on quality and continuously laying the solid foundation for the growth of the company. We strongly believe we can deliver value to all our partners.

At end of the day, we wish we can demonstrate the following value to you: quality product, differenciated product and a product with real warranty.
We honor what we commit. We expect to work with partners for long term with sustainable befefits to both sides.
Diffusion- absorption summarizes the cooling process, which is also called absorption.
Main features of diffusion- absorption
How absorption cooling works?
This system uses three operating fluid as the component: Ammonia – water –Helium, Ammonia as refrigerant, water as absorbent, Helium as diffusant. The refrigeration core is mainly composed of generator, condenser and evaporator. Under the environment of low press in the evaporator, liquid ammonia evaporates into helium and mixes with gas helium together. In the absorber, gas ammonia is released from the mixture and is absorbed by water to be strong ammonia solution. Then, in the heater it is heated and the ammonia evaporates from the solution. Passing through the condenser, steam ammonia is cooled down to ammonia. After that, ammonia water reenters the evaporator. As a result of physical changes, endothermic-exothermic reaction is brought into being time and time again.
European absorption technology
Thanks to great contribution of engineers from Europe, and their numerous years of experience, Dellware developed absorption technology with Helium, new corrosion inhibitor ensuring the product safety efficiency and reliability. Dellware is the only manufacturer in China who can offer quality absorption refrigerators from 15 liter to 300 liter.
Fuzzy logic temperature control
In comparison with electro-mechanical thermostat, Dellware can also provide PLD fuzzy logic temperature control option. It has these advantages: Precise, Automatic defrosts, low fluctuation of temperature. This technology provides longer enduring cooling, accurate temperature for proper nutrition and all food value. Energy consumption is very low as well.
Automatic minibar, Internet of things
As a combination of Dellware’s cooling expertise and partners’ intelligence, Dellware’ s computerized minibar is the new generation of automatic minibar that offers accurate billing system. The significant saving in labor costs makes it the first choice of hotel chains.
