What Is the Circulating Water Bath with Cooler Unit Used For?
Strength results on bituminous mixtures depend strongly on temperature, so asphalt specimens are brought to the test temperature in water before Marshall or indirect tensile testing, and cement specimens likewise need a stable water temperature while they cure. The operator sets the temperature on the digital regulator; the heater or the cooler unit beneath the bath brings the water to it, and the re-circulating unit keeps it even throughout the tank. Asphalt specimens stay in the bath for the conditioning period and go straight to the test, while 40 × 40 × 160 mm cement prisms can be cured and stored in water at 20 °C.
What to Specify When Ordering
- Quantity — the number of water baths required.
- Application — asphalt specimen conditioning, cement specimen curing or both, with the temperatures needed.
Frequently Asked Questions
Which tests is the Circulating Water Bath with Cooler Unit used for?
Its main uses are bringing asphalt specimens to temperature in water before Marshall and indirect tensile testing, and curing 40 × 40 × 160 mm cement specimens in water with storage at 20 °C.
Why does the bath need a cooler unit?
Indirect tensile conditioning of bituminous mixtures calls for water at 5 °C or from 5 to 25 °C, often below room temperature, and the cooling system makes these temperatures obtainable.
What temperature range and capacity does it have?
The bath works from +5 to +60 °C with an accuracy of ± 1%, holds 40 l, and has inside dimensions of 550 × 360 × 200 mm.
How is the temperature controlled?
A two-channel electronic thermo regulator with digital display controls both heating and cooling and maintains the set temperature automatically, while a re-circulating unit keeps it uniform.
How is the bath constructed?
Polished stainless steel lines the tank inside an insulated sheet steel case, and the cooler unit with its refrigeration compressor sits under the bath; the unit measures 830 × 480 × 950 mm and weighs about 62 kg.
Which standards are listed?
The standards listed are EN 12697-34, EN 12697-12, EN 12697-23, ASTM D1559, ASTM D5581, ASTM D6927 and AASHTO T245; the power rating is 2000 W.
