Building materials B-type freeze-thaw testing machine
MIT-682-3-01 Type B Freezing and Thawing Test Machine for Building Materials
A two-layer structure of the test chamber and water tank with low heat and power loss.
This is a "Gas Phase Freezing and Water Melting (Method B)" testing machine for building materials such as slate, siding, gypsum board, and paint. By stacking the test chamber and water tank vertically, it features an energy-saving design that reduces thermal loss during the "melting phase" of the constant temperature water circulation and the pump power required for water circulation. Additionally, the water tank lid opens from the top for easy maintenance and also serves as a step stool, making it practical. Other considerations for maintenance include an external fan motor for cold air circulation. 【Features】 ● During "Water Melting": Unique upper and lower dual-chamber structure allows constant temperature water to circulate just below the test chamber, eliminating thermal loss. ● During "Gas Phase Freezing": Warm water naturally falls back from the test chamber to the water tank, reducing energy consumption for circulation. ● Easy operation with a touch panel. ● Peace of mind with a self-diagnosis function in case of trouble. ● User-friendly design that considers maintenance. ● Direct circulation structure achieves stable temperature distribution.
