Blue Lagoon Spa UV-C / Copper Electrolyzer – Replacement Housing (B212013AM)

Blue Lagoon Spa UV-C / Copper Electrolyzer – Replacement Housing (B212013)

Replace a cracked, broken, or damaged body on your Blue Lagoon Spa UV-C or Copper Electrolyzer unit with this genuine OEM replacement housing (article code B212013). The housing is the outer shell that encloses the UV-C lamp, quartz sleeve, and electronics, forming a watertight chamber that directs spa or hot tub water past the UV-C lamp for disinfection. This part is compatible with three Blue Lagoon Spa models across a wattage range of 12 to 21W: the T5 21W 230V, the PL-S 12W 230V, and the 15W 120V USA variant.

When Does the Housing Need Replacing?

The housing is a durable component but can fail due to physical impact, UV degradation of plastics over time, or cracking caused by freezing temperatures if the unit was not properly winterised. A damaged housing can lead to water leaks around the unit, reduced UV-C effectiveness due to bypassing of water around the lamp chamber, and in severe cases electrical safety hazards. If the housing is cracked, warped, or no longer seals correctly, replacing it is far more economical than buying a complete new UV-C system.

About the Blue Lagoon Spa UV-C System

The Blue Lagoon Spa UV-C range is designed specifically for hot tubs, spas, and small pool installations. The unit treats water flowing through the system with UV-C light at 253.7 nm, destroying bacteria, viruses, algae, and other micro-organisms without adding chemicals. It significantly reduces the amount of chlorine or bromine needed to maintain hygienic water quality, resulting in softer water that is gentler on skin and eyes. The Copper Electrolyzer models additionally use copper ionisation to suppress algae growth, providing a dual-action treatment system.

Compatibility

This housing is compatible with the following Blue Lagoon Spa models:

• Blue Lagoon Spa UV-C T5 21W 230V
• Blue Lagoon Spa UV-C PL-S 12W 230V
• Blue Lagoon Spa UV-C 15W 120V (USA)

Always verify your model number before ordering. If in doubt, check the label on the existing unit or consult your installation documentation.
