WES - Dosing Cube

WES Ltd, Hampshire, UK Tel: +44 (0)1256 819777 www.wes.ltd.uk DOSING CUBE Principle A portable fully enclosed chemical dosing system comprising a weatherproof Polyethylene rotationally moulded enclosure into which is fitted an Grundfos/Alldos Digital dosing pump complete with con-trol valves, leak detection switch, control box with timer, etc. Uses Designed primarily for temporary or emergency use to dose Chemi-cal from an IBC or other existing storage vessel. The CUBE can also be used as an interchangeable modular system for permanent dos-ing systems. Ease of Use By utilising compact Alldos Digital dosing pumps which have a user interface that lets you enter the dosing rate you want directly on the screen, the CUBE enclosure can be small enough to be portable. Furthermore, with a very wide turndown ratio (100:1 for smaller pumps 800:1 for large pumps) and no need for complicated stroke rate calculations, the CUBE is truly “plug & play”. Features: • Polyethylene enclosure IP54 rated with integral drip-tray, resis-tant to most Chemicals, lockable toggle catch closure, carrying handles, clear window. • Grundfos/Alldos Digital Dosing Pump allowing direct operator entry of dose rate. Also, allowing manual or auto operation modes with direct input of pulse or 4-20mA flow proportional control sig-nals. • Dual contained pipework connections. Suction & delivery pipe-work can be dual contained with the outer sleeves connected di-rectly to the CUBE. Any pipework leakage is detected by the switch in the drip tray. • Control box with 7 day/24 hour timer—can be simply set to stop/start at pre-set times. All CUBE’s are dual voltage 110 or 240v - 110v plug on flying lead supplied as standard. • Safety splash screen—even with the lid open, the pump head, valves & pipework are covered with a clear uPVC screen. • Dose rates—Models available allowing dose rates as low as 0.025 l/hr or up to 150 l/hr. • Drip tray/bund—The integral drip tray will contain any leakage and the level switch will inhibit the pump. A drain plug allows any residual chemical to be drained safely. • Health & Safety—With integral chemical containment, automatic leak detection cut-off & splash screens, etc. The CUBE provides a safe dosing system for both operator & environment.

Other valve & pipe materials available. Operating Voltage Dual - 240 or 110 vAC (110v plug on lead supplied as standard) Dual - 240 or 110 vAC (110v plug on lead supplied as standard) Dual - 240 or 110 vAC (110v plug on lead supplied as standard) Control Via built-in controller. The programmable timer/controller allows stop/start times for dos-ing for each day of the week in increments of one hour. The unit has a 6 year battery back up memory. Further control options are available through the pumps inputs/outputs (I/O) Bund/Drip Tray The Cube itself forms a bund, which incorporates a level switch for leak detection. The pump is turned off if a leak is detected. Safety/Splash Screens 2 off - Viewing window in lid section plus internal clear cover over pump head, valves & pipework. The internal cover allows full protection if the unit is opened whilst the pump is in operation.
