Freeze/Thaw Concrete Testing Machines

• Custom concrete testers available to meet your needs.
  This includes user-defined displays and control options, multiple machine control stations, and custom sample racks.
• Backed by a one-year warranty – from date of shipment to original purchaser – for parts and workmanship, including labor allowances, when performed by an authorized Scientemp service agent.

Our Freeze-Thaw Machine complies with the ASTM C666 specification, Procedures A and B, which tests for resistance of concrete to rapid freezing and thawing. Our standard model holds up to eighty (80) 3” x 4” x 16” concrete test beams. However, internal specimen racks can be custom made to accommodate special specimen sizes.


The internal chamber, lid liner and specimen racks are constructed of 304 stainless steel. The external cabinet is welded steel with an enamel finish. The cabinet is insulated with 4” of urethane foam.

The refrigeration system utilizes an air-cooled or water-cooled condensing unit as specified by the customer. The evaporator tubes are high quality, brazen-finned tubing. Four air circulating fans in the lid provide uniform air temperature in the freeze-thaw chamber.

Standard 20 Block Freeze-Thaw

The Scientemp Freeze-Thaw machine can be operated in manual mode or automatic mode and has a programmable time and temperature profile that has capabilities to meet many various needs of the user. It is ideal for large-scale quality testing of concrete aggregates as well as research and development programs for various concrete additives.

Larger capacity models feature forklift channels for easy installation. The temperature controlled thaw-water tank and circulating pumps are also skid mounted. The freeze-thaw machine is tested at the factory in the exact arrangement that the customer chooses, so the interconnections are prefabricated. Power wiring and interconnections are required to make the machine functional.

Standard 20 Block Freeze-Thaw Lid

This high quality machine features: 304 stainless steel work surfaces, internal chamber, lid liner, and specimen racks. The external cabinet is constructed of welded steel with a durable powder-coated finish. The cabinet chamber is insulated with 4” of urethane foam. The evaporator tubes are high quality, brazen-finned tubing. The refrigeration system utilizes an air-cooled or water-cooled condensing unit as specified by the customer. Circulating fans in the lid provide uniform air temperature throughout the chamber. The lid operates with an electric linear actuator for safe and easy operation.

Standard 20 Block Freeze-Thaw Controls
with Access Panels Removed

This high quality concrete test machine has an attractive instrument panel which features:

● Off/On/Auto Switches
● Off/On Status Lights
● Cycle Counter
● Safety Interlocks and Alarms
● Thaw-Water Temperature Control
● Overall Cycle Control

The operator interface control provides easy input of the cycle time and temperature. A programmable three-channel, 10” diameter circular chart recorder is provided to monitor air temperature and two test specimens. The machine’s minimum cycle time is approximately two hours, while the maximum cycle time is user defined.

Scientemp also offers two upgrade options that offer improved touch-screen user interface, network connectivity for digital logging of data, or an independent personal computer which provides the user interface for control with a much larger display and independent data logging.

The advanced option models are controlled with an emergency stop button and a touch screen panel. The touch screen has several displays that allow the user to program time and temperature profiles, select operating modes, view status of equipment and logic functions, operate the equipment, view the status of alarms and alarm history, and navigate through the displays. The advanced models also offer factory connectivity through a Virtual Private Network for factory based technical support, system monitoring, troubleshooting, and program downloading of applications. (Service contract required for factory technical support after warranty period).

Advanced 20 Block Freeze with Touch Screen Control
and Data Logging to Server

The professional option models are controlled with an emergency stop button, a local lid switch, and dedicated computer which provides a much larger user interface. The dedicated computer can be installed locally or in a remote location, such as an office or alternate lab location. The dedicated computer has several displays that allow the user to program time and temperature profiles, select operating modes, view status of equipment and logic functions, operate the equipment, view the status of alarms and network connectivity and data logging to the dedicated computer that is independent from your server-insuring continuous data collection through network failures and upgrades.

The professional models also offer factory connectivity for Virtual Private Network for factory based technical support, system monitoring, troubleshooting and program downloading of applications. (Service contract required for factory technical support after warranty period).

Scientemp will also customize your concrete testing machine to meet your needs. This includes user-defined displays and control options, multiple machine control stations, and custom sample racks.

Scientemp Freeze-Thaw concrete equipment is backed by a one-year warranty – from date of shipment to original purchaser – for parts and workmanship, including labor allowances when performed by an authorized Scientemp service agent.
