INOX Pro

STAINLESS STEEL EXPANSION TANKS

AISI 304 Stainless Steel and food grade internal membrane for temperatures up to 158°F are the main features of this range.  ZILMET USA offers a product of nearly unlimited endurance for a variety of special applications: compensations of water expansion in sanitary hot water production; anti-water hammering; heating systems; all applications along coastal areas, where brackishness is the cause of rapid corrosion of carbon steel; wherever maximum hygiene is necessary.

 

These expansion tanks are equipped with an absolutely non-toxic food grade membrane with world wide certifications from demanding organizations for the approval of parts used in the food industry.   Our high quality materials, manufacturing procedures and continuous ZILMET USA quality control, make our INOX PRO tanks a long-lasting life cycle and no need for special maintenance.

 

The Z8,  Z12 and Z18  STAINLESS STEEL expansion tanks are fit for all applications near coastal areas where the presence of brackishness or harsh chemical environments that rapidly corrode all parts made of plain steel. They allow water expansion in domestic heating systems equipped with boilers or heat exchangers.  They are also used in every application where ultimate hygiene is required, as in a house or a community.

 

MINI-Z160 and the MINI-Z50  WATER HAMMER ARRESTORS

This line prevents pipe damage, decreases noise in plumbing systems, are compact and have a long life cycle.

 

What is WATER HAMMERING?

Water hammering is a sudden pressure surge in a system due to the sudden arrest of the water flow by a quick closing of a valve, gate valve, due to the starting/stopping of a pump.  Pressure  surges cause serious vibrations to the pipes and the plumbing system in general.

 

MINI-Z160 APPLICATIONS

Putting the MINI-Z160 near the checking element reduces the pressure surge to acceptable levels, absorbing the water impact with the pneumatic cushion of the pre-charged mini vessel.  The sudden arrest of the fluid column is therefore transformed to a gradual slowing down.

 

MINI-Z50 APPLICATIONS

The Z50, sized between the Z160 and the Z100 is an excellent water hammer arrestor in hydraulic systems, compensating the water expansion in hot sanitary water production systems with small boilers or heat exchangers.

 

MAXIMUM DRAW DOWN!!

The membrane expansion tank capacity is decidedly superior to ordinary tanks.  Therefore, less tank volume at equal water yield.

 

COMPRESSOR ELIMINATION

An air feeder is no longer necessary as an air cushion.  The expansion tank separated from the water by the rubber membrane keeps the expansion tank constantly under pressure.

 

USE WITH AGGRESSIVE WATER

The membrane expansion tank can be used even with hard water.

 

RAPID INSTALLATION

Its size and shape allow for easy and quick installation.

 

LIFE SPAN

Maximum duration of the expansion tank is assured by membrane design so it cannot bend or rub against the wall, because it is fixed above at the connection and below at the flange.  The expansion tank life span is practically unlimited as it has a replaceable membrane.
