CLOSED TYPE EXPANSION TANK

Closed Expansion Tanks Closed Expansion Tanks

Expansion Tank (Series- EET)

Series EET Expansion Tank (Replaceable bladder type  pressurized)

The pressurization system shall include an Emerald, replaceable bladder type expansion tank which will accommodate the expanded water of the system generated within the normal operating temperature range, limiting this pressure increase at those components in the system to the maximum allowable pressure at those components. It shall maintain minimum operating pressure necessary to eliminate all air. The only air in the system shall be the permanent sealed in air cushion contained in the replaceable bladder type tank, Model No. EET. Dimensions shall be as indicated on the drawing.

The expansion tank shall be welded steel, constructed, tested for a working pressure of (125 psig/8.6 bar) (175 psig/12 bar) and air pre charged.

The tank shall be supported by steel legs or a base (integral ring mount) for a vertical installation. Each tank will have a heavy duty replaceable butyl bladder.

Benefits:

  • No Maintenance expenses

  • Membrane (Bladder) replaceable.

  • No Energy required

  • It checks constant Water Flow either contracting & expansion of the water in the system.

  • Low installation cost.

  • Controls the Water Hammering and stabilize the water pressure in the system.

  • It reduces pumps cycling & save energy.

  • The tank provides equal pressure at all the points in the plant.

  • It prevents corrosion in the pipe line.

  • No maintenance is required.

Expansion Tank Series (EET) Pressurized

For Closed Hydronics Heating & Chilled Water Systems

The pressurization system shall include an Emerald, replaceable bladder type expansion tank which will accommodate the expanded water of the system generated within the normal operating temperature range, limiting this pressure increase as these components in the system to the maximum allowable pressure at those components.

It shall maintain the system pressure within the maximum allowable limit. Only air in the system shall be the permanent sealing and cushion contained in the replaceable bladder type tank, Model No. EET. Dimensions shall be as indicated on the drawing.

The Expansion Tanks can also be manufactured in Stainless Steel as per Pressure Regulations (JIS / EEC).

Emerald Expansions are constructed in Mild Steel as per IS2062 / Stainless Steel as per SS304. The Expansion Tanks as constructed as per AMSE / IS-2825 pressure standard (Non-fired). Each tank has a working pressure of (125 psig/8.6 bar) and air pre charged.

The tank shall be supported by steel legs or a base (integrated mount) for vertical installation. Each tank will have a heavy duty replaceable butyl bladder.
