Five-star hotels have high requirements for the flatness of bed sheets, duvet covers, and pillowcases. “The laundry factory to undertake the linen cleaning business of the five-star hotel must have a chest ironer” has become the consensus of the hotel and the laundry factory. How does the laundry factory choose a chest ironer that suits its own needs?
The ironing principle of the chest ironer is through the rotation of the suction roller so that the sheets, quilt covers, and pillowcases that need to be ironed are rolled by the heating chest under the drive of the drying cylinder, wrapped in felt. In the rolling process, through the heating of the linen and the dehumidification of the suction duct, the linen quickly achieves the role of thermal expansion and cold setting.
The principle is the same as ironing clothes in the laundry shops. However, the roller ironers press the sheets by heating and tension, which is the main reason why the ironing quality of the chest ironer is better than that of the roller ironer.
In addition, the chest ironer uses a suction duct to ensure strong dehumidification. In the ironing process, it can quickly evaporate the water vapor forced out of the linen, greatly enhancing the linen ironing efficiency and achieving the purpose of rapid styling. Also, the steam pressure of the chest ironer is generally higher than that of the roller ironer, so the heating temperature is higher, and it is conducive to the leveling of the linen.
Analysis of Negative Effects in Some Laundry Plants
The use of steam-heated chest ironers in Europe and the United States is very common, and the efficiency and flatness of ironing linen are also good. However, in some laundry plants in other countries, the effect of buying European and American brands of steam-heated chest ironers is not good. The main reason is that the steam-heated chest ironer’s steam pressure in Europe and the United States is 9-13 steam pressure, while the steam pressure of steam-heated chest ironers used in laundry plants in other countries is generally not high enough. Most of them are about 5-7, and some are even lower. Or the steam saturation is not enough. This will lead to poor ironing quality and low production efficiency in the ironing process.
Some laundry plants with insufficient steam pressure need to put the linen in the dryer for a few minutes before drying, and remove some water before ironing, which will not only increase steam consumption but also lead to low production efficiency.
In the above situation where steam pressure is insufficient and pre-drying costs time and energy, if you still want to provide good services for star customers, CLM can offer you a better choice: a direct-fired chest ironer.
CLM is dedicated to building a leading brand of no(less) steam laundry equipment and introducing European technology. We took the lead in the innovation and built a direct-fired chest ironer that is easily operated, highly efficient, more energy-saving, flatter, and longer-lasting.
In fact, CLM has built several laundry plants with no steam in Hunan, Sichuan, Shanghai, Beijing, Hubei, Fujian, Jiangxi, and other areas, bringing them bigger profits. Let’s see the advantages of a highly efficient direct-fired CLM chest ironer.
CLM Direct-fired Chest Ironer
Intelligent Control System
CLM direct-fired chest ironer adopts an advanced PLC intelligent control system and is equipped with a 10-inch HD touch screen so that the program editing can be easily set. 100 ironing programs are customized to perfectly control all kinds of ironing specifications, ironing temperatures, chest temperatures, and the pressure of air cylinders to meet the ironing requirements of different linens.
Imported Flexible Chest
Developed and designed by a team of experienced engineers in Europe, CLM’s flexible chest is made of two stainless steel plates. The flow and distribution of thermal oil inside the chest are analyzed by computational fluid dynamics, which allows the oil pressure to be low and the ironer to maintain a constant temperature at high speed.
In addition, the flow and distribution of thermal oil in the flexible chest have been visualized in an unprecedented way. Computational fluid dynamics is expensive, but very accurate.
The CLM direct-fired flexible chest solves the problem of uneven distribution of thermal oil, and the oil inlet pipe is changed to 6 groups to ensure the uniform distribution of thermal oil in the tank, and there will be no cold spot to make the equipment more energy saving.
CLM uses a triple-heated heat exchanger and is the most energy-efficient ironer on the market. Due to the large diameter of the oil pipeline inside the exchanger, the flow of thermal oil through the exchanger is the largest in the industry. At the same time, thanks to the large distance between the pipelines, the thermal oil will not be overheated, so the thermal oil life is longer, and the dual oil circuit design is safe and stable.
The High-quality Spare Parts Prolong the Service Life
The electrical components are imported brands. The performance is more stable, reducing the failure rate and extending the service life. The electric box door adopts the glue sealing process to achieve the highest waterproof and dustproof protection IP68.
Easy Maintenance Design
Power transmission for CLM chest ironers has the advantages of no adjustment and zero maintenance, using an independent motor direct drive without a belt, chain, and other dangerous power transmission. Each chest is equipped with an inverter, and the speed of each roller is controlled by advanced electronic means.
High-tech thermal insulation board design, all-around sealing process production, and stainless steel wrap, which avoids heat loss, greatly reduces heat consumption, improves production efficiency, and creates a comfortable production environment. The bridge connection and the ironing chest have synchronous circulation heating, which contributes to higher thermal efficiency.
CLM chest ironer is equipped with a powerful, modular dehumidification system. Because dehumidification is closely related to the amount of water evaporation, each roll is equipped with an independent dehumidification device, which effectively improves the running speed of the ironer.
The light-duty structure has better stability and higher quality standards. The structure of the roller surface makes the flow of steam stable so that the linen after ironing has better flatness.
The suspension automatic calibration system automatically adjusts worn felt, thermal expansion force, and mechanical stress. It ensures a uniform distribution of cylinder pressure throughout its life cycle.
CLM direct-fired chest ironer also has great advantages in terms of energy saving. Next time, we will continue to share the advantages of CLM direct-fired chest ironers in the use cost.
