Description

Trebles Pressbox is an electronic pump controller designed to automate pump operation and provide dry-run protection (variant dependent).

Typical applications

Automatic pump control
Dry-run protection
Domestic/Residential booster automation

The lightweight aluminium enclosure and supplied EasyMount wall bracket help make the PRESSBOX quicker and easier to install. Compared with many floor-mounted alternatives, the unit is easier to handle while still offering greater tank capacity than equivalent wall-mounted-only options.

The digital controller also supports BMS connectivity as standard via two contacts: one common alarm and one programmable alarm output that can be configured to suit the application parameters.
