NOWPAK LINER-BASED CANISTER SYSTEM

User Manual | Entegris, Inc.

• A three-way valve must be installed in the inert gas

supply line to allow for safe canister pressurization
and depressurization.

• Filled canisters must be handled using appropriate

canister handling equipment. Entegris recommends
using a four-wheel drum dolly to move 200-liter
canisters. Never roll a filled canister on the chime
edge or on its side!

WARNING: 200-liter canisters must have internal
pressure released before removing the dispense
connector. If the canister is pressurized, the
dispense connector may fly upward with great
force while being removed. Serious injury or death
may result.

WARNING: The maximum operating pressure is
101 kPa (14.7 psig) within the United States. Outside
of the United States follow local regulations, which
may require lower dispense pressure to be used.
Use a pressure relief valve to prevent over pressur-
ization of the canister. Dispense connectors with
preset pressure relief valves are available.

IMPORTANT: The maximum internal canister pressure is
196 kPa (28.4 psig) for canisters larger than 40 liters. Do not
allow the pressure inside any canister to exceed this rating.

SECTION 3: SYSTEM INFORMATION

—

The liner-based canister system consists of a reusable
stainless-steel outer shell and a single-use inner liner
filled with a desired chemical. The canister is available
in sizes from 4 to 200 liters and can be fitted with
a variety of dispense connector types to suit your
dispensing requirements.

In use, a dispense connector is installed on the
canister, Figure 1, and connected to the end user’s
application. The inner liner collapses as the chemical
is dispensed. When empty, the canister is ready to be
refurbished with a new, pre cleaned liner and refilled
with chemicals.

Replacement liners will safely contain the most
hazardous chemical. Liners are available in
fluoropolymer materials for highly aggressive
chemical fills, or coextruded polyethylene
materials for less aggressive applications that
require ensured purity or gas barrier protection.
