CW-5200T, a Small Air Cooled Chiller Ideal for a Vietnamese Acrylic CO2 Laser Cutter Owner

 Mr. Tran from Vietnam owns an acrylic CO2 laser cutter and most of his clients are the local residents who are about to open a new store and want their shop names made in acrylic. His store is not big and the acrylic CO2 laser cutter has been accounted for much of the space. He had an old water chiller, but that chiller was quite space consuming and broke down so often, so he wanted to change for a smaller one with more reliability. With the recommendation from his friend, he called us and we selected small air cooled chiller CW-5200T for him.

S&A small air cooled chiller CW-5200T has a low profile design with superior cooling performance and reliability. It is characterized by ±0.3℃ temperature stability,offering a precise temperature control solution to the glass tube of the CO2 laser cutter. Being only 58*29*47cm(LXWXH) , small air cooled chiller CW-5200T is very space saving, which is very ideal for users who has limited space like Mr. Tran.

How can users know enough water is added into industrial water cooling system which cools aluminum plate fiber laser cutter?

 It’s quite necessary to change out water for industrial water cooling system which cools aluminum plate fiber laser cutter. After changing out the water, the next thing is to add/refill with fresh circulating water. So there is a question - how can users know enough water is added into the industrial water cooling system?

Don’t worry. Each of S&A refrigeration based industrial water cooling system is equipped with water level gauge which has 3 color areas. Yellow area indicates ultrahigh water level; green area indicates normal water level; red area indicates ultra-low water level. Therefore, when the water reaches the green area of the water level gauge, users can stop adding. 

After 18-year development, we establish rigorous product quality system and provide well-established after-sales service. We offer more than 90 standard water chiller models and 120 water chiller models for customization. With cooling capacity ranging from 0.6KW to 30KW, our water chillers are applicable to cool different laser sources,laser processing machines, CNC machines, medical instruments, laboratory equipment and so on.

This Rack Mount Industrial Chiller Unit is Really Beyond My Expectation, a U.S. Handheld Laser Welder User said

 Three weeks ago, we receive a phone call from the United States.

Mr. Smith: Hello. I am from the U.S. and I have a handheld laser welder. My original water chiller is broken and I am looking for another chiller that is similar to my original one. My original water chiller has ±1.5℃ temperature stability and it is kind of big. It would be better if the chiller is smaller but with the similar cooling ability. By the way, my handheld laser welder is 1000W. Any recommendation?

S&A: Yes, we do. Our industrial chiller unit RMFL-1000 could be your ideal choice. This chiller is especially suited for handheld laser welder and has a rack mount design, which indicates great mobility and enables integration into other machine layout. Besides, rack mount industrial chiller unit RMFL-1000 features ±1℃, which is more precise than your original water chiller. More importantly, rack mount industrial chiller unit RMFL-1000 is designed with dual cooling circuit - one is for cooling the fiber laser source of the handheld laser welder and the other is for cooling the laser head, which can greatly avoid the condensed water and saves time and space. 

Mr. Smith: Wow, that dual cooling circuit surprises me! This chiller is really beyond my expectation! Please arrange the delivery of 1 unit of rack mount industrial chiller unit RMFL-1000 to my place before this Saturday. 

And now, the chiller has been working so well and Mr. Smith is so great that he made the right choice.

Industrial Cooling System CW5200T Provides Great Protection for Cardboard Laser Cutter of a Turkish Client

 Mr. Sedef works in a Turkey based cardboard packing box manufacturing company. As a staff who has been working there for 10 years, he witnessed the company growing to be a big company. At the same time, he also witnessed the change of the production machines - from traditional cutting machine to the latest laser cutting machine. Since the day his company introduced the cardboard laser cutters, the productivity has been increasing. However, without the protection provided by industrial cooling system CW-5200T, the cardboard laser cutters could not maintain their excellent cutting performance in 24/7 working schedule, according to what Mr. Sedef said.

Cardboard laser cutter is powered by CO2 laser tube which works hand in hand with industrial cooling system. During operation, CO2 laser tube is prone to generate extra heat which can affect the stability of the CO2 laser tube and in worst case scenario, lead to the breaking of the CO2 laser tube. Therefore, the working performance of the cardboard laser cutter is dependent on the the accuracy and the precision of the cooling system. And now with S&A industrial cooling system CW-5200T, the cardboard laser cutter can be under great protection all the time. 

S&A industrial cooling system CW-5200T is designed to deliver high precision cooling performance. With ±0.3℃ temperature stability, it can provide precise temperature control for the CO2 laser tube of the cardboard laser cutter, reducing the risk of the glass tube breakage. Besides, industrial cooling system CW-5200T is equipped with an intelligent temperature controller, which provides automatic adjustment of water temperature and indicates water temperature and ambient temperature as needed.
