Aluline has more than 30 years experience in Grease Management Systems, both in design, maintenance and installation. We can maintain systems and give relevant advice to all of our customers. It is only a viable working system that has kept many customers loyal from our inception in 1993. A Grease Management System is sized to accommodate and use space available, to fit or retro fit traps in kitchen areas. This is recommended as care of units is then borne by catering management. A trap which isdesigned and sized to fit the space available may require more physical maintenance and shorter periods on the cleaning cycle. Traps without a regular planned maintenance programme will not meet standards and may cause problems in the system, and pump stations.
