JIS A 6909 allows for temperature cycling tests of finishing materials for construction!
This is a device that can perform the "thermal cycling test" for architectural finishing materials as specified in JIS A 6909. It can also be used for the "freeze-thaw test method in air" as described in JIS A 1435 for exterior building materials. Additionally, it is capable of conducting "wet-dry cycling tests" as an optional application. It features an energy-efficient design that reduces heat loss and power consumption through its unique structure. Maintenance considerations have also been taken into account. 【Features】 - During "immersion": The unique upper and lower dual-chamber structure allows constant temperature water to circulate from the water tank at the bottom of the test chamber, eliminating heat loss. - During "cooling": Warm water naturally falls back from the test chamber to the water tank, reducing the energy required for circulation. - The fan motor for cold air circulation is external, minimizing troubles and simplifying maintenance. - Easy operation via a touch panel. - The self-diagnosis function provides peace of mind in case of trouble. - The direct circulation structure ensures stable temperature distribution.

Detailed information
-
Design considering maintainability The motor for cold air circulation is external, making it less prone to troubles.
-
Space-saving type is also available. We also have a compact space-saving type that does not protrude in front of the aquarium.
-
The operation is easy to understand with a touch panel! You can easily manage operations and test conditions from the touch panel. In the event of any trouble, the abnormal areas, causes, and countermeasures will also be displayed on the touch panel, allowing you to address the issue immediately. Leakage checks are also performed automatically, and the location of any leakage will be displayed.
Company information
Marui is promoting the development of new testing equipment and the automation of testing devices through the introduction of cutting-edge technology, and has released the automatic pressure testing machine "Hi-ACTIS-2000," a concrete freeze-thaw testing device, and the specimen polishing end face finishing machine "Haikenma Tsuru Tsuru." Additionally, the simple ground bearing capacity measuring device "Caspole," developed through joint efforts of government, academia, and industry, is also a significant achievement.
