Watlow , a designer and manufacturer of electric heaters, controllers and temperature sensors, have introduced the CAST-X 500 circulation heater.
This small, lightweight circulation heater is ideal for demanding gas and liquid applications, is intrinsically safe and will not burn the fluids being heated.
The CAST-X 500 heater is suited for applications where fluid cleanliness is critical, because the gas or liquid being heated never comes in contact with the heater.
This is a performance requirement in the semiconductor, analytical and foodservice equipment industries.
The heater's applications include the heating of solvent, DI water, air, CO2, nitrogen, diesel fuel and printing ink, as well as packaging sterilisation, analytical instrumentation, steam generation and pasteurisation in foodservice applications.
The CAST-X 500 circulation heater is constructed of a helical coiled tube cast into an aluminium body with a replaceable cartridge heater installed in the centre.
The cartridge heater can be replaced with a higher or lower wattage unit as required for the application. The aluminium body serves as the heat transfer media between the cartridge heater and the coiled tube where fluid is being heated.
The construction of the heater allows it to be used where thermally sensitive materials are being heated, such as paints, resins and flammable materials.
The aluminium mass acts as a thermal flywheel and ensures accurate temperature control of the fluid to prevent degradation.
The robust cast-in aluminium construction assures longer heater life and accurate temperature control, and the stainless steel fluid path assures compatibility with many different materials.
The CAST-X 500 circulation heater's non-welded construction provides high pressure operation up to 3000PSI, operates up to 177°C (350°F), minimises potential leakage and self drains when mounted vertically.
The CAST-X 500 circulation heater's compact size reduces space needs in customers' equipment and assures quick response due to its low mass, making it a better overall thermal solution than oversized heat exchangers.
The CAST-X 500 is a new and small heater in Watlow's CAST-X product line. The CAST-X 1000 offers a maximum working fluid pressure of up to 1500PSI and process temperature up to 121°C (250° F).
The CAST-X 2000 features a maximum working fluid pressure of 5000PSI and a process temperature of 93°C (200°F) to 260°C (500°F). Watlow is currently taking orders and shipping the CAST-X 1000 and 2000 in only one day.
