1. Introduction

An industrial washing machine is specially designed for a large-scale operation to ease the washing process faster with low water consumption. Not just are they deployed for fabrics, they work perfectly in industries such as medical, food processing, manufacturing, automotive, and logistics for cleaning and sanitising to make things germ-free.

Some of the industries using washing machines are as follows:

1. Hotels and Hospitality: Industrial washing machines are widely used in hotels, resorts, and other hospitality establishments to handle the large volume of linens, towels, and bedding that require regular washing.

2. Healthcare Facilities: Hospitals, clinics, and other healthcare facilities rely on industrial washing machines to clean a significant volume of bed linens, patient gowns, towels, and other medical textiles.

3. Restaurants and Food Processing: Industrial washing machines are used in the food industry to clean uniforms, aprons, kitchen towels, and other linens. Ensuring hygiene in such environments is crucial.
