Description

AbsoluteUltra Clear Pond UV Steriliser; 55W — High-flow vortex UV clarifier for larger ponds

A big pond with a heavily loaded pump outruns a small UV unit long before the water has spent enough time near the lamp to do any good. AbsoluteUltra Clear Pond UV Steriliser; 55W (SKU: UCP55) is the largest model in Absolute’s Ultra Clear range, stepping up to a 55 W quartz-sleeved UV-C lamp inside the same turbulent vortex housing as the smaller units, so water is still forced into a spiral path around the lamp rather than running straight past it, but at a flow rate the smaller 36 W and 11 W models are not rated for. The extra wattage and longer lamp are what let this unit handle a recommended maximum flow of 9,250 L/h, making it the model to reach for on larger koi ponds, heavily stocked systems or anywhere the existing pump is already running close to the smaller units’ limits.

The flow path, construction and safety features carry straight across the range: a quartz glass sleeve for maximum UV-C transmission, a viewing window to confirm at a glance that the lamp is lit, and a built-in UVC cut-out microswitch that disconnects power to the lamp the moment the housing is opened, so there is no exposure risk during a lamp or sleeve change. The body is UV-resistant plastic with an IP67 outdoor rating and Australian RCM electrical approval, designed for horizontal mounting in-line with the pump on 240 V power. Maximum pump head is 7.0 m and the inlet and outlet are 1 in BSP, matching the fittings on the 36 W unit so the two can share pipework in a system being upgraded. The PL-L55W TUV lamp is specific to this model; the 36 W model (UCP36) uses the shorter PL-L36W TUV lamp and the 11 W model (UCP11) is sized for ponds well below either of these flow rates.

Usage & Application

When to Use

• Large ponds and koi systems: Flows up to around 9,250 L/h that smaller UV units cannot keep pace with.
• Heavily stocked systems: Higher bio-load and feeding rates that drive more frequent algae blooms.
• Upgrading from a smaller unit: Where pump output has grown beyond the 36 W model’s flow rating.
• Pathogen control without chemicals: UV-C exposure as an alternative to dosing a large system.

How to Use / Installation Process

• Mount horizontally in-line: Fit the unit after the pump, within its 7.0 m maximum head.
• Connect 1 in BSP fittings: Plumb into the existing pipework; fittings match the 36 W model.
• Check the viewing window: Confirm the lamp is glowing once the unit is powered.
• Isolate power before opening: The cut-out microswitch disconnects the lamp automatically when serviced.
