DN50 Insulation Jacket

This Greenlife DN50 insulation jacket is shaped to fit a DN50 (2in) closed circuit filter housing, reducing heat loss from the larger housing and stopping condensation forming on its casing in a plant room. WrekinWater supplies it as a genuine like-for-like replacement rather than generic pipe lagging, sized for the fittings and union on the DN50 unit. It's aimed at anyone replacing a damaged or missing jacket on a larger commercial-scale filter housing.

Signs you need this part

• The jacket is damaged, compressed or missing from a DN50 housing.
• Condensation forming on the bare casing in an unheated or larger plant room.
• A noticeably warm pipe run around the filter, pointing to heat escaping.
• A replacement DN50 housing supplied without its insulation jacket.

At DN50 the housing carries a larger volume of heating water and has more surface area to lose heat from than the smaller DN20-DN40 units, so leaving it bare wastes more energy and raises the risk of condensation in a plant room. The jacket is shaped to the DN50 housing's union and valve fittings, giving proper coverage where a generic lagging wrap would leave gaps around those connections. Fitting it doesn't change how the filter performs, but it cuts ongoing heat loss and reduces the chance of damp forming around a larger, harder-to-dry-out housing.

WrekinWater has been trading as a family-run business from Bettisfield, Shropshire for 15 years, serving more than 50,000 customers and holding an Excellent Trustpilot rating. Stocking the correct DN50 jacket here means it's shaped to fit a larger housing properly rather than relying on generic lagging.

How to fit it

1. Isolate the heating system before removing any existing damaged jacket.
2. Clean the DN50 housing casing so the replacement jacket sits against a dry surface.
3. Fit the jacket around the housing, aligning cut-outs with the union and valve fittings.
4. Secure the fastenings so the jacket wraps snugly with no gaps around the larger housing.
5. Check the union remains accessible through the jacket for the next service.
6. Return the system to normal use and check for condensation once it's back up to temperature.
