MAESTRO™ by EJ
MAESTRO™ is the fruit of hard labour by the highly trained product development teams at EJ. The goal was to design the best sewer drain cover in terms of performance, durability and user-friendliness. Through finite element analysis and dynamic testing, EJ achieves this with outstanding results.
MAESTRO™ boasts the finest quality components in executing its innovative functions. The cushioning insert of the sewer drain cover is fabricated from premium EPDM (ethylene polypropylene), widely used for excellent resistance to heat, steam, ozone, weathering, diluted acids, alkalies, and polar substances. The frame cover seating features a groove to minimise the deformation of the material. The 100% recyclable material can be clipped onto the access cover with no glue required, reducing the impact on the environment. Inspired by the automotive industry, the cushioning insert guarantees long lasting performance in both high and low temperatures.
MAESTRO™ is designed with three ductile bars placed under the cover for a state-of-the-art slam locking mechanism. The elastic bars also help maintain the central position of the sewer drain cover to resist lateral movement and seating wear. In a closed position, the cover will not be prone to opening by small surges of back pressure. On the other hand, sewer drain covers will function as a pressure relief valve that opens itself up when subject to greater surges of back pressure, before resting back to its natural closed position. Pedestrian or vehicle traffic will eventually shut the cover completely, staying in place with the hinge and slam lock. This feature makes for the enhanced security of network assets, providing first-line deterrent security against theft and related cases.
Ideal for city council and authority branding, MAESTRO™ sewer drain cover can be branded with the local coat of arms or corporate logos. Customised badging establishes onsite recognition and asset ownership. The strong patronage of EJ includes the QUU; Christchurch, Nelson and Wellington City Councils; and APLNG (Asia Pacific LNG Pipeline).
As for the frame, MAESTRO™ features four double skin zones for optimal rigidity and facility to the most intense traffic stresses. The frame is anchored with double skin and slots on the frame, bolted through four holes onto the concrete head. EJ also designed the frame with optimised seating area for lowest pressure and longest lasting seating without seating wear.
