Water Treatment Equipment

Non-chemical water treatment equipment.

Chemical dosing controls scale by adding something to the water. Non-chemical treatment controls it by changing how the dissolved hardness behaves. The second approach costs nothing to run, produces no dosing waste and cannot overdose.

What to know before you specify

Hard water carries dissolved calcium and magnesium. As it warms and evaporates in a cooling circuit those salts concentrate, come out of solution and bond to the hottest surfaces in the system, which are exactly the surfaces you need clean. A millimetre of scale on a condenser tube can add double digit percentages to compressor energy.

Our inline units are installed directly in the pipeline with flanged connections. Water passes through the treatment chamber on its way to the plant, so there is no bypass loop to balance, no dosing pump to service and no drum of chemical to store and handle.

For applications that genuinely need ion exchange we also supply and commission conventional softening plants. We will tell you plainly which of the two suits your water and your duty, because specifying the wrong one is expensive for both of us.

Set of three stainless steel non-chemical water treatment chambers with bolted flange ends

01 Water Treatment Equipment

Non-Chemical Water Treatment Equipment

Flanged inline treatment chamber for cooling and process circuits

A stainless steel treatment chamber that bolts straight into the pipeline. Water passing through is conditioned so that hardness salts precipitate as a soft suspended powder rather than binding as hard scale to pipe and tube walls.

Features

  • Stainless steel body with standard drilled flanges
  • No electrical supply and no consumables
  • No moving parts, so nothing to wear or service
  • Handles hardness levels that defeat conventional dosing
  • Existing scale is gradually lifted from wetted surfaces

02 Water Treatment Equipment

Industrial Water Softening Plant

Ion exchange plant for boiler feed and process duty

Where the process genuinely requires hardness removed rather than conditioned, such as boiler feed water, we supply skid mounted ion exchange softening plants sized to your flow rate and inlet hardness.

Features

  • FRP or mild steel rubber lined pressure vessels
  • High capacity strong acid cation resin bed
  • Manual, semi automatic or fully automatic regeneration
  • Brine measuring tank and injector supplied
  • Duplex arrangement for uninterrupted soft water

Stainless steel ScaleOff scale preventer installed vertically in a green chiller plant room pipeline

03 Water Treatment Equipment

Electrostatic Scale Preventer

Inline scale preventer for chiller and condenser circuits

Installed on the condenser water line of a chiller plant, the scale preventer keeps heat transfer surfaces clean without dosing. It is the unit we most often retrofit into existing plant rooms where scale has already begun to cost energy.

Features

  • Retrofits into existing condenser water pipework
  • Keeps approach temperature stable across the season
  • No blowdown increase and no chemical handling
  • Stainless steel body suited to continuous duty
  • Directional flow arrow marked on the body
