Extended Life For Water Pipings In Buildings

Yokota Manufacturing has launched a new degassing equipment ASP series for degassing of gas-dissolved liquid, which enables supply of deoxidized water to prevent pipes or boilers from rusting.

Yokota Manufacturing Co, Japan, has launched a new degassing equipment ASP series for highly efficient and quick degassing of gas-dissolved liquid, which enables supply of deoxidized water to prevent pipes or boilers from rusting.

Main part of this equipment is a degassing pump with novel structure patented in USA, UK, Japan, other.

This degassing pump, with an interlocked vacuum pump, extracts and discharges even dissolved gas in liquid with extremely high efficiency.

Its patented mechanism comprising an orifice and multiple types of impellers generates strong decompression and centrifugal force to continuously extract and separate the dissolved gas from the liquid.

The separated gas is then drawn out by the vacuum pump.

The outstanding degassing power is evident by the remarkable reduction of dissolved oxygen in water, for example, from a near 8ppm at the intake side to 0.5ppm or less at the outlet side.

or less).

Feeding such deoxidized water, instead of raw water, to pipes or boilers in the buildings and factories can prevent metal pipes or boilers from rusting and extend their life span.

This equipment degasses liquid mechanically without using any chemical additive such as hydrazine.

Therefore it is safe and does not cause contamination.

Also, there are no clogging problems like that with membrane type equipment, and no troublesome maintenance is required.

Moreover, with the self-priming and pressurized discharge capabilities, all processes including suction, degassing and transfer of liquid are achieved in this single, compact equipment, unlike conventional methods which require installation of several components.

Thus, use of this degassing equipment ASP series reduces costs of liquid processing.

Models are available with bores from 25 to 40mm, flow capacity from 0.01 to 0.06ton/min.

and total head from 5 to 25m.

This degassing equipment is also capable of performing a wide range of tasks in other industrial degassing/defoaming operations including deaeration of foods and beverages, degassing of gas-containing chemical liquid, deaeration of lubricants and hydraulic oil, and production of ultra-pure water.
