LX18, LX30C, LX30H, LX40C, LX30 specifications

The Hobart LX series of dishwashers, including models LX18H, LX18C, LX30, LX40C, and LX30H, offers a combination of efficiency, advanced technology, and robust design suitable for various commercial kitchen environments. These machines are engineered to handle differing volumes of dishwashing tasks while maintaining high standards of cleanliness and sanitation.

The LX18H and LX18C are designed for lower-volume operations, making them ideal for smaller establishments such as cafes and bistros. The LX18H model features a high-temperature wash, ensuring effective sanitization through elevated water temperatures. It includes an energy-efficient operation with a low water consumption rate, making it both eco-friendly and cost-effective. The LX18C, on the other hand, utilizes chemical sanitizing, allowing for flexibility in cleaning procedures. Both models have quick cycle times, facilitating high productivity during peak hours.

Moving up in capacity, the LX30 and LX30H models cater to medium-volume commercial kitchens. The LX30 offers a high-efficiency wash system that allows for thorough cleaning in less time, benefiting fast-paced environments. The integrated booster heater ensures the water reaches optimal temperatures for sanitization, while a user-friendly control panel simplifies operation. The LX30H variant also focuses on high-temperature sanitization, making it suitable for establishments that require stringent hygiene standards.

The LX40C model stands out within the series as a versatile option for high-capacity dishwashing needs. It combines advanced technology with superior construction, allowing it to manage heavy workloads without compromising speed or efficacy. The wash, rinse, and drainage cycles are optimized to minimize water usage while maximizing cleaning power. Its chemical sanitization option provides consistent results, suitable for large commercial kitchens where the demand for cleanliness is paramount.

Enhancing user experience across the LX series is the inclusion of features such as automatic door opening, which allows for convenience and ease of use. Additionally, built-in diagnostics help in maintaining the machine's performance, reducing downtime. The robust stainless-steel construction ensures durability, while a compact design allows for versatility in placement within the kitchen.

In summary, the Hobart LX series—comprising LX18H, LX18C, LX30, LX40C, and LX30H—offers customizable solutions for a variety of dishwashing needs. With their energy-efficient features, advanced sanitization technologies, and user-centric designs, these models exemplify Hobart's commitment to delivering high-quality, reliable dishwashing solutions for the demanding environment of commercial kitchens.
