Sample Cooler type SDC4400
is a shell and tube type heat exchanger in which the sample to be
cooled, flows through the tube and the cooling liquid (usually
water) flows through the shell side. The SDC4400 type of cooler has
a double helical coil of size 1/4" OD with no welded joints in the
entire coil length. The cooling fluid enters the cooler from bottom
and exits from the top after completing three counter passes across
the inner and outer baffle tubes. The 3-pass counter flow design
together with a large (0.24 m2) heat transfer area ensures high
cooling efficiency even with H.P steam samples.
High cooling efficiency
due to 3-pass counter flow design - minimum vibration and scaling
even at low cooling water flow rates.
Heavy duty, rugged design
with pressure ratings to cover most steam or process samples. Coil
is a single continuous tube with no welded joints.
Can be easily mounted in
cooling water lines without using special supports. Shell can be
easily dismantled without disconnecting sample lines.
Very high heat transfer
surface area for unit cost. Wide variety of materials of
construction to cover most sampling applications.
Sample Coolers type SDC4400 are pressure vessels designed to ASME
Sec Viii Div.1.
Certification of manufacture and pressure tests by 3rd party inspn.
agencies are possible.
