How we design for you?
We promise we use the design software sold by a well-known European HAVC software company.
Through 8 years of cooperation with them, we have designed, processed and exported coils and unit coolers to various countries all around the world.
All of customers feedback is that the actual cooling performance is almost the same as the theoretical design value.
We will send you the 3D model drawing, data sheet together with the quotation list as you required.



Case study
Project name: air cooler for
Vietnam cold roomMy client needs 12units of 50 kw air cooler that made of all stainless steel for cold room to storage fruit.
At the begining we were difficult to going on because my client knowed little about what he need.
Then I tried to ask him step by step: (It only took 5 days to
conclude a transaction. )
Me: May I know what medium will you use for the unit cooler?
Client: What is medium ? Sorry I don't undestand.
Me: Thats's ok. Medium is something to cool the temperature. It maybe water, glycol, CO2, ammonia, refrigerant and etc.
Client: Thanks. The medium for my air cooler should be 25% glycol.
Me:OK we have solved one problem. Next, what is the room temperature and the glycol inlet temperature?
Client: room: +5 ℃, glycol: -5℃. Totoro, I am a little worried becasue I can't sure if those datas are reasonable.
Me: Don't worry about it. I will send you the sketch and data sheet that calculated by professional software to check all specifications.
Me: There is last thing need to confirm:
Defrost type? Water defrost, air defrost or electrical defrost?
Client: E
lectrical defrost.
Me: Please kindly confirm the data sheet, sketch and the quotation list.
Client: Perfect! My engineer has checked that. Everything is ok. Please directly send me the PI.
In summary, to design a glycol air cooler, thoses information are needed:1.How much percent glycol you use? Like 20%.
2.Cooling capacity?
3.Glycol pumped inlet temperature?
4.Room temperature?
5.Material you need? Stainless steel tube aluminum fin galvanized steel frame or not?
6.Defrost type? Water defrost, air defrost or electrical defrost?
