The GMS range of de-aerator units heads comprise of a stainless steel mixing head and a stainless steel immersion tube.

The unit is designed to be maintenance-free with a stainless steel body (wetted parts). Gaskets and all bolting are supplied with the unit.

Thermal Insulation

  • Type MA: Consists of 50mm mineral wool with dimpled aluminium cladding. This gives good thermal insulation and a quality finish. For some installations there will be a high risk of damage to the factory fitted insulation. In these instances it is preferable to insulate on site.
