Water Treatment Industry Equipment

Supplier: Grimwood Heating

The most common solutions Grimwood provides for the water treatment industry are heaters for CIP processes and caustic anticrystalisation heaters. In waste water treatmant plants we also provide duct heaters to heat ventilation air to prevent condensation. In some cases due to the presence of methane, these can become potentially explosive atmospheres, and in these cases Grimwood can provide IECEx certified hazardous area heaters to comply with the requirements of Australian Standards.


Grimwood Flanged Immersion Heaters for CIP Process Heating and Caustic Anticrystalisation Heaters
Grimwood Flanged Immersion Heaters can be designed and manufactured to suit either static tanks, and for circulation or in-line applications, depending in client requirements. The Grimwood range of Flanged Immersion Heaters are designed and manufactured in Australia to provide peace of mind for users by utilizing local knowledge and skills, coupled with the best materials and components.

The Australian made Grimwood heating elements are specifically designed for each application, with material selection and design details only finalized after a full review of the application.

By using locally designed and manufactured product fully complying with Australian Standards engineers and contractors are assured of meeting their obligations and don’t run the risk of having to rework installations during commissioning or project hand over to meet client requirements.
  • Ideal for heavy duty industrial applications
  • Standard models available with indoor and weatherproof terminal enclosures
  • Available in a wide range of power ratings –up to 1MW
  • Flanged Heater assemblies are designed to be inserted in a tank nozzle in the side of a tank. With larger tanks, multiple heaters can be inserted from one or more sides.
The Grimwood range of Heaters are manufactured with element supports when required for vibration resistance and to prevent element sagging.

Screw Plug Heaters
Used to fit into smaller tanks and vessels to provide heating up to 20kW. Available with brass or SS316 bosses, alloy 800 or alloy 825 element sheaths.

Withdrawable Heaters
DN50 (2IN) withdrawable heaters are used in similar applications to Screw Plus Heaters, but where it is essential to be able to replace the elements without emptying the vessel, or coming in contact with the vessel contents. Immersion tubes are available in copper, SS316 or Duplex stainless steel.

Duct Heaters
Duct Heaters are used to raise the temperature of the air stream in ventilation systems, particularly to prevent the formation of condensation in high humidity applications. Also available in hazardous area versions to suit potentially explosive atmospheres.

Drum and IBC Heaters

Drum and IBC Heaters are used to condition stored chemicals to prevent degradation, and for avoiding caustic crystalisation at low temperatures

Control Panels
Grimwood can also supply a fully featured control panel with over temperature policemen, thyristor power control and network capabilities to suit your BMS or SCADA system
