Hygiene Applications of box drains

Hygiene is a critical consideration in any food preparation or processing environment. Effective drainage helps to mitigate hazards from the external environment and is essential to maintaining a safe and hygienic operation.

Box drains are an effective option for drainage in food preparation and processing areas. They are designed to minimize the risk of contamination and ensure easy cleaning and maintenance.

The hygienic design of box drains starts with the material. They are typically made of stainless steel, durable, and easy to clean. The smooth surfaces resist corrosion and minimize the risk of contamination.

Box drains are also designed for easy installation and cleaning. They have removable grates that can be removed for cleaning without having to remove the entire drain. The grate design also prevents debris from entering the drain and clogging it.

Box drains create a safe and hygienic environment in food preparation and processing areas. Their durable construction and easy-to-clean design make them an ideal solution for protecting against contaminants.

Material Technology Advantages

Material Technology Advantages

Advantages of using Stainless Steel in Buildings and Construction: Using steel in construction offers many benefits over other materials. Some advantages of using steel in construction are listed below.

  • Fire and heat resistance: Steel is mainly composed of iron, which creates a very strong material that is difficult to melt. Because steel is resistant to fire and heat, it is a popular choice for building projects where preventing fires is essential.
  • Durability: Steel is also highly resistant to wear and tear, making it an ideal material for construction projects that require stable structures.
  • Versatility: Steel can be used in various ways, from beams and columns to reinforcing other building materials. As a result, steel offers a high degree of versatility, making it an ideal choice for a wide range of construction projects.
  • Steel is an extremely sturdy building material, making it ideal for construction projects that require a great deal of strength.
  • Economic benefits: The use of steel can also offer economic benefits, as it is often cheaper than alternative materials such as concrete or timber.

Stainless steel’s many benefits make it the perfect choice for demanding drainage applications. There is a wide selection of different types of stainless steel available, each with its specific advantages. Austenitic stainless steels, for example, are some of the most widely used and encompass grades 304 and 316L. These materials perform well in food processing, dairy, brewing, pharmaceutical, chemical and petrochemical industries.

Although the marine grade is often used at about 316L, it is not the only grade available. Different grades have various characteristics. If you don’t know which one to use for your application, don’t hesitate to reach out to Hofen for help assessing material suitability.

Performance

Corrosion and temperature resistance

Corrosion and temperature resistance are important factors when choosing a drainage system for an industrial application. Hofen manufactures all of its products from stainless steel grade 304 or grade 316L, both highly resistant to corrosion. In addition, all products are pickled and passivated to ensure no corrosion problems at the joints.

For applications where highly aggressive liquids or very alkaline cleaning agents are used, systems made from stainless steel grade 316L are recommended. This grade of stainless steel is even more resistant to corrosion than grade 304, making it an excellent choice for challenging environments.

Pickling & passivation of the box drain

Pickling & passivation of the box drain

Ultimate finishing

Stainless steel can be damaged by bending, cutting, punching, and welding during manufacturing. This damage can lead to corrosion over time. Pickling and passivation are chemical processes that help restore the physical properties of stainless steel and prevent further damage.

  • It provides better corrosion resistance.
  • Achieving a smooth, uniform finish is essential for any project.
  • Easy for cleaning and maintenance
  • Long-lasting product

  • Internal radii

All internal radii are equal to or greater than 1/8″ (3 mm), significantly improving cleaning results.

  • Edge infill

The most crucial aspect is creating a seamless transition between the floor drain and the surrounding floor. This prevents cracks in the floor from developing, which may provide a home for germs.

  • Full drainability

Drainability is critical for your vehicle’s health. It prevents standing water, unpleasant scents, bacterial growth, and chemical risks by draining completely.

Grates
  • Grates

You can choose it from a wide array of stainless steel grates that can hold up to 25 tons. The unlocked grates allow you easy access to the box drain whenever you need to perform maintenance.

  • Hygienic joints

The firm’s deep-drawn bodies guarantee smooth outlines, eliminating crevices where germs may hide.

  • Drain body

The shape will be a V-shape if the width is less than 12″ (300 mm).

  • Drain body

There is a reinforced bottom for widths 16″ (400 mm) and greater.

Stainless Box Drain Grates Relevant Load Standards

The most important standard in the US is ASME: A112.6.3 – 2016, which covers floor drains. It does, however, not adequately address linear trench drains. Hofen has independent accreditation for floor drainage to ASME 112.6.3 and EN 1253, but all trench drains are subjected to EN 1433: 2002 Drainage channels for vehicle and pedestrian areas.

A comparison chart is provided below, equating stresses (psi) from ASME A112.6.3 – 2016 with the EN 1433 Load Class A – F categories. It is divided by internal channel widths and includes a side-by-side comparison to EN 1253: 2015 Gullies for Buildings. Each product’s certification is available upon request.

Outlet Options

Hofen stainless steel box drains can be connected to underground pipework in the following ways:

Outlet Options

The simplest way to connect pipes is with a vertical spigot out of the box. The connection can be made using a no-hub connector or Hofen stainless steel push-fit pipe system. Usually, this entails installing drain and piping before concrete/floor is laid.
