Freezing and Thawing Apparatus (B method: freezing and thawing in water)
Contents of page
Outline of Product Technology
Product number: MIT-682-3-01
A freezing and thawing apparatus for building material.
This testing apparatus has two-layer (upper and lower) structure to alternately repeat freezing and thawing of specimens automatically with "freezing in air and thawing in water (B method)" based on testing standards. The upper and lower layer of the testing chamber and water chamber reduces the heat loss in the constant temperature water circulation when "thawing" and also reduces the electric power for pump. The water chamber has a lid that opens upward and is easily maintained and the lid can be a foot stool. The cold air circulation fan is motor-separated type and it is also easily maintained.

Detailed Information
arge touch panel that allows easy operation and checking
A large color touch panel (10 in.) provides easy operation and setting.
Pressing the "Preliminary operation" button you can confirm how to set specimens and make test settings.
It also enables efficient management of the test as you can check the test status (time passage, temperature of testing chamber, temperature of testing tank, remaining number of cycles, total number of cycles, and test ending time) immediately.
You can see the operating instructions using the touch panel when you have a trouble.

Direct circulation provides even temperature distribution and saves energy
MARUI products use the "direct circulation" system with less heat loss and even temperature distribution.
In "freezing" cycle, it circulates cool air with the cooler and fan equipped on the testing chamber.
In "thawing" cycle, it circulates constant temperature water in the water chamber equipped right under the testing chamber and does not lose heat during circulation.
Warm water "naturally drops" from the testing chamber into the water chamber, and the energy for the circulation is saved.

The original design that makes maintenance easy
The water chamber has a lid that opens upward and is easily cleaned and maintained. The lid can also be a foot stool.
The fan for cool air circulation has an external motor to reduce deterioration and simplify maintenance. The fan in the testing chamber can be replaced separately when damaged and is cost-saving.

"Test time reservation function" for efficient testing plan
MARUI's freezing and thawing apparatus (with touch panels) have built-in "reservation function" to reserve the starting date and time for the test.
This function help you make efficient testing plan such as starting on a holiday.

"Self error detection" to deal with troubles
In case any trouble happens, the touch panel indicates the part in trouble, causes, and solutions, so that you can deal with the troubles quickly.
An electric leak is also checked and detected automatically, and indicated by the specific part.
