• The Environmental Chamber system offers you the ability to expose your new

product to extreme temperatures at rapid rates of change. This has proven to be an

extremely effective means of identifying failure-prone components and assemblies in

the shortest possible time. The unique characteristics of Chart, Inc. Environmental

Chamber systems are of key importance in achieving this effectiveness.

• The staff and employees of Chart Industries, Inc. thank you for choosing our product.

Please don’t hesitate to call us with any questions or comments that you may have. If

after reading through this manual you are not confident in carrying out any task,

please call Chart Industries Technical Service team at 1-888-877-3093.

SAFETY FIRST!

Chart Environmental Chambers Description of Safety Features

Safety Information

 Your Chart equipment is provided with several safety systems designed to help

prevent accidental damage to product and equipment, and avoid injury to

personnel. Always operate this equipment in accordance with the procedures set

forth in the OPERATION section of this manual.

 The safety systems described below should be checked at least once every 30

days, and any inoperative or questionable conditions must be corrected before

resuming operation.

 Servicing of this equipment and its associated utility service must be done only by

properly trained personnel!

Liquid nitrogen, and high voltages can all cause severe injury or death if not properly

handled.

WARNING! - EXTREME TEMPERATURES AND PRESSURES:

This equipment produces extreme temperatures and uses pressurized fluids.

Failure to follow instructions and use proper safety precautions can cause injury or

death

WARNING! - ASPHYXIATION HAZARD:

This equipment uses LIQUID NITROGEN (LN2), which can displace oxygen and

cause severe injury or death due to lack of oxygen. It is important to monitor

oxygen levels in the working environment around the chamber to assure a safe

working environment for all personnel.

Chart Environmental Chambers Description of Safety Features

Description of Safety Features

On each unit, there are a number of features, which help to ensure safe operation. These

features are:

❏ Temperature High/Low Limit Control:

A user-programmable limit control is provided as an independent measure of safety

against thermal runaway (hot or cold), which could occur from, but not limited to, the

following:

 Programming error

 Primary controller failure

 Thermocouple breakage

 Heater SSR failure

 Circulation blower failure

The limit control is wired into the control devices to provide a totally independent safety

system. A separate thermocouple is provided for the limit control and located inside the

air plenum. If this device has reached an alarm condition, the system must be reset by

pressing the “Chamber Reset” button on the control console.

WARNING!: The alarm set point of this device should never be set higher

than +200°C or lower than –80°C as these are the

maximum design temperature of the system.

It is important to note that this safety controller does not protect from a possible failure of

the cooling solenoid valve. It is possible for this valve to fail and allow liquid nitrogen to

continue flowing into the chamber, resulting in extremely cold temperatures. As a result,

Chart recommends changing the solenoid valve on a regular basis as a preventative

maintenance measure against such occurrences.

Chart Environmental Chambers Features

Features

❏ Temperature Control System:

Heating is accomplished with resistive electric elements, while cooling is accomplished

by blowing liquid nitrogen into the chamber. The liquid nitrogen is vaporized through

nozzles and the cold vapor is circulated over the products in the chamber so that liquid

nitrogen does not touch the product under test. Electric heaters are carefully selected and

arranged to provide extremely rapid rates of temperature change without exceeding safe

design limits of heat elements. The heaters and nitrogen nozzles are located in the air

conditioning plenum.

CAUTION: Although the chamber is designed to use very small amounts of liquid

nitrogen, the resulting nitrogen gas is vented out of the chamber. It is

important to monitor the oxygen levels in the working environment around

the chamber to ensure safe operating conditions.

The liquid nitrogen control is done by a solenoid valve. The solenoid valve is chosen for

its compact size and high reliability. The temperature controller tells the solenoid valve

when to open based on the temperature inside the chamber.

❏ Air Circulation Blower:

The chamber is equipped with a non-corrosive blower wheel, which provides air

circulation to distribute temperature controlled air and minimize thermal enclosure

temperature gradients. Baffles provide output air openings to direct the air flow out of the

duct and into the workspace of the chamber. The blower is located in the air

conditioning plenum. The blower draws air flow across the heater and nitrogen nozzle

and out into the workspace of the chamber.

❑ Instruments:

Temperature is controlled by a Watlow Series 96 temperature controller. The input to the

temperature controller is a type T thermocouple. The control thermocouple is mounted in
