Preface Before You Begin Safety first! Before you attempt to use your MTS product or system, read and understand the Safety manual and any other safety information provided with your system. Improper installation, operation, or maintenance of MTS equipment in your test facility can result in hazardous conditions that can cause severe personal injury or death and damage to your equipment and specimen. Again, read and understand the safety information provided with your system before you continue.

Introduction This manual describes how to install the Series 651 Environmental Chambers onto a load unit and how to work with liquid nitrogen (LN2). The MTS Series 651 Environmental Chambers let you test materials and components within a range of temperatures, from -129–540° C (-200–1000° F). Cooling is accomplished with the use of gases introduced to the chamber. Heating is accomplished with two electrical heating elements. An electric fan and baffle diffuse the heat for uniform temperatures.
Note Clean any debris produced from testing away from the environmental chamber. For example, carbon fibers can short the heater elements which causes them to stop working. WARNING The environmental chamber is not rated for combustible liquids. When heated, flammable and combustible liquids can explode and cause personal injury, or equipment damage. Documentation • Do not use flammable or combustible liquids in the environmental chamber. • Always operate the chamber with the door closed.
Chamber models The following table lists the differences between the environmental chamber models. Each environmental chamber can be used with any load unit but is recommended for specific load units.

Series 651 Environmental Chamber
Installation Environmental chambers are installed in load units using a mobile cart designed for the chamber. The chamber is installed from the rear of the load unit. Most of the environmental chambers have U-plugs. Removable sections (Uplugs) in the top and bottom walls of the chamber allow the cart-mounted chamber to be placed in position around the specimen and grips. Each U-plug consists of two pieces, one stationary and the other removable.

Using the Environmental Chamber Cart The environmental chamber is typically installed onto an MTS load unit. A mobile cart accessory provides a stable, easy-to-move platform for the environmental chamber and allows the chamber to be quickly and easily installed onto, or removed from, a load unit. The mobile cart has casters to move the cart and adjustable feet to stabilize the cart when the environmental chamber is stationary. It also has a hand-operated screw jack for raising and lowering the chamber.
Installing the Environmental Chamber To install the environmental chamber onto an MTS load unit: 1. If you have an environmental chamber with U-plugs, you can install the grips and specimen before installing the chamber. See your grip manual. 2. Set the environmental chamber onto the mobile cart. 3. Arrange the cables and hoses so that they do not interfere with cart movement. WARNING When moving the chamber and cart assembly it is possible to damage cables or hoses.
Eurotherm 2404 6. Use the hand-operated screw jack to adjust the height of the chamber so that the cart’s lift arms are slightly higher than the top surface of the load unit’s baseplate. Note The Model 651.05-02 Environmental Chamber includes feet for tabletop applications. Adjust the height of the feet for the application. 7. If you have an environmental chamber without U-plugs (Models 651.04-01 and 651.05-02), install the grips now. See your grip manual.
11. Route cables and wires for the thermocouple, extensometers, and so forth out through the small access ports provided in the walls of the chamber, and then plug the ports with insulation or port plugs. 12. Pack mineral insulation (MTS part number 011-335-202) around the grip extension rods in the access ports. Note Optional inserts are available from MTS Systems Corporation. They can also be custom made. Teflon can be used for applications up to 204° C (400° F).
WARNING The environmental chamber is not rated for combustible liquids. When heated, flammable and combustible liquids can explode and cause personal injury and equipment damage. • Do not use flammable or combustible liquids in the environmental chamber. • Always operate the chamber with the door closed. • Do not override any safety features. • Do not modify the chamber without consulting MTS Systems Corporation. Male, 1/2 inch, 45° Flare Connector To connect an LN2 supply tank to the chamber: 1.
2. Connect a coolant gas exhaust line to the vent on the rear of the chamber to carry exhausted cooling gases away from the test site. The exhaust line must have an inside diameter at least as great as the diameter of the vent, and should be as short as possible, with as few bends as possible to prevent back pressure in the chamber. 3. Turn the liquid withdrawal valve on the supply tank on before beginning a test.
Venting the LN2 after use After using LN2 cooling, complete the following steps to prevent coolant from becoming trapped in the line between the supply tank gas valve and the coolant solenoid valve. This procedure must be performed after each test if another test will not be started within a few minutes. CAUTION Do not leave LN2 coolant in the line after use. LN2 left in the line could rupture the line or damage the solenoid when the liquid warms up and expands.

Operation To remove a specimen from the environmental chamber following a test: WARNING The chamber interior and the specimen can be very hot or very cold following a test. Working in the chamber before it has returned to room temperature can cause burns or freezing injuries. Take precautions to avoid touching hot or cold surfaces with bare skin. Use appropriate tools and personal protection equipment. Consult your lab’s safety guidelines and procedures. 1. Stop the test and turn the chamber switch off.
