If your laundry plant washes 2500 sets of linen every day, which one do you prefer, a tunnel washer or an industrial washing machine? We can make a comparison from the aspect of using cost to see the performance of tunnel washers and industrial washing machines.
Let’s see the laundry equipment used in these two methods:
Tunnel washer configuration: CLM 60 kg 16-chamber direct-fired tunnel washer system
Individual machine configuration: 8 pieces of 100kg industrial washing machines and 5 pieces of 100kg industrial dryers
Comparison of Water Consumption
The average water consumption of a CLM tunnel washer washing 1kg of linen is 5.5 kg. If every set of linen is calculated as 3.5 kg, then 2500 sets of linen is 8.75 tons. As a result, the whole water consumption is 48.125 tons.
The average water consumption of an industrial washing machine washing 1kg of linen is 20kg. Then, the total water consumption of 2500 sets of linen is 175 tons.
Gap: The daily water consumption of industrial washing machines is 126.875 tons more than the tunnel washer. The yearly gap is 46309.4 tons, and the annual additional water bill needs to be about 185,000 yuan according to the water price of 4 yuan/ton. 
Comparison of Energy Consumption
❑ Steam Consumption During Washing
CLM tunnel washer: use 2.625 tons of steam to wash 2500 sets of linen
Industrial washing machine: use 4.375 tons of steam to wash 2500 sets of linen
The daily steam consumption of individual equipment is 1.75 tons more than tunnel washer. As a result, the daily additional steam bill is 490 yuan and the annual additional bill is 179000 yuan according to the steam price of 280 yuan/ton.
❑ Gas Consumption during Drying (Towels)
The linen after being washed by the CLM tunnel washer should be dried by the CLM tumble dryer.
CLM direct-fired tumble dryer: consumes 7 cubic meters of gas to dry 120kg of towels.
The proportion of towels in all 2500 sets of linen is 40% and the weight is about 3500kg. The gas consumption is about 204 cubic meters.
Kingstar 100kg steam-heated dryer: consumes 180kg of steam to dry 100kg of towels.
The steam consumption of drying 3500kg of towels is 6.3 tons.
This is under the premise of using the Kingstar heavy-duty industrial washing machines and Kingstar energy-saving and high-speed dryers. If it is an ordinary washing machine and dryer, the steam consumption will be higher.
The daily gas cost of drying 3500kg of towels every day is 816 yuan according to the price of 4 yuan/cubic meter. If industrial washing machines are used to wash and industrial dryers are used to dry towels, the steam cost during drying is 1764 yuan. As a result, using a direct-fired tunnel washer system can save 948 yuan a day. An annual saving is about 346000 yuan.
By the above comparison, we can calculate the all energy costs of tunnel washer systems from washing to drying. It saves about 710000 yuan annually.
Employees Hiring
Tunnel washer system:
It is a complete system. From washing to drying, generally, only one employee is needed. The whole operating process is controlled by the computer and completed by the mechanism.
Industrial washing machine:
When using 8 washing machines and 5 dryers, at least 4 employees are needed. For the laundry plant, it needs to spend 3 more labor costs per month. According to the calculation of 4500/ month per employee, the monthly labor cost needs to be 13,500 yuan more, and the annual labor cost needs to be 162,000 yuan more.
Comprehensive Analysis
On the whole, laundry plants whose daily washing capacity is 2500 sets of linen use tunnel washer systems can save 872000 yuan. Though the price of a tunnel washer system is higher than the price of the industrial washing machine in the initial investment, the gap can be compromised by the cost savings of a year and a half.
In addition, when the orders rise or when the laundry capacity fluctuates in peak or low seasons, the tunnel washer has better compatibility. A tunnel washer can wash about 5000 sets of linen in 10 hours. While the max throughput in 10 hours of 8 industrial washing machines and 5 industrial dryers is only about 2500 sets of linen. When facing rising orders, the laundry plants that use industrial washing machines and dryers need to work overtime or add equipment to realize timely delivery.

Case Study
Taizhou Yajie Laundry Plant is located in Taizhou, Zhejiang Province, and was opened in May 2024. From the official business to the present, in less than a year, the daily volume of washing has been more than 3,000 sets. Such a development rate is quite excellent among the new laundry plants. At the beginning of its establishment, Taizhou Jiajie went through multiple comparisons and finally chose the CLM direct-fired tunnel washer system, high-speed ironing line, and towel folder.
CLM equipment has good stability, high efficiency, and high intelligence, and can control the entire work process with computer programs. Therefore, new employees can quickly master the technology after a period of training and adjustment, reducing the difficulties in management of the newly opened washing plant, so that they can have more energy to develop the market. In addition, the energy-saving effect of direct-fired equipment is very obvious. The washing cost can be slightly lower than other laundry plants. At the same time, the quality of washing and ironing is higher than other laundry plants, which has been unanimously recognized by customers in the local area, and the business volume has also developed rapidly.
