How do I correctly size a grease treatment system? Graphic

Under building regulations Part H section 2.21, it specifies that “drainage serving kitchens in commercial hot food premises should be fitted with a grease separator complying with prEN 1825-1 and designed in accordance with prEN 1825-2 or other effective means of grease removal”.

By using our grease trap calculator, we can identify your nominal size (NS) number and recommend suitable grease management systems to suit your needs.

Under the BS EN 1825 calculation, we can determine the correct size by two methods:

OPTION 1 - Type of Kitchen

This looks at the type of operation, such as restaurant, school, hospital, or hotel and requires the input of average meals per day as well as the kitchen’s operational hours per day.

OPTION 2 - Type of Equipment

This looks at all of the grease-producing equipment within the kitchen that requires treating as well as the quantity and dimensions of each particular sink or kitchen equipment. This needs to be entered into the grease trap calculator to accurately work out the required nominal size grease management system.
