7 Operations
7.9 Operating a Water Heating or Cooling Contherm™ or Brine Cooling Contherm™
The installation and set-up of the Contherm
™
for a water or brine cooled configuration is described in Chapter Five, Section
5.10 Installing A Water or Brine Cooling System. Typical installation drawings of the configuration are provided in Figure 5-13.
Refer to those portions of Chapter Five as necessary while performing the initial start-up and operating procedure that
is provided in Table 7-11.
Two typical Contherm
™
cooling system configurations are shown in Figure 5-13. One configuration shows an open loop set-up
where product temperature control is required. In this configuration, the cooling water/brine is piped in a series arrangement
through each Contherm
™
. This arrangement minimizes water consumption while maintaining high velocities through the media
annulus thereby ensuring efficient heat transfer.
The second configuration shows a temperature control loop using a centrifugal pump. In this configuration, the pump circulates
the cooling fluid through the Contherms
™
media jacket. In configurations with more than one Contherm
™
, this set-up is usually
utilized for the final Contherm
™
when the product outlet temperature must be controlled.

™
Step Action
1
Using water as the test “product,” start flowing it through the Contherm
™
via the product inlet. When water begins
exiting the unit’s product chamber via the product outlet, start the rotor.
Note: For best results, adjust the flow rate and temperature profile of the water
2 Turn on the water or brine cooling system. Inspect the media piping for leaks. If your system does not contain a
temperature control loop, adjust the coolant flow to control the product outlet temperature and proceed to Step 5.
3 Set the automatic temperature controller to 50° F (10° C). After several minutes of operation, check product inlet
and outlet temperatures. The outlet temperature gauge should read approximately 50° F (10° C). Repeat this
step for several other temperature settings.
4
Set the controller to your desired product temperature setting. The product outlet temperature gauge should reach
this temperature within five to ten minutes.
5 When you are satisfied that the Contherm
™
is operating properly with water as the product, drain and flush the
water “product” from the system.
6 Your Contherm
™
is now ready to begin service.
Note: The product should be flowing through the system and diverted back to the source before the cooling media
is turned on. This will prevent a freeze up from occurring as the product will not be exposed to a colder than
normal cylinder surface. Divert the product back to the source until the product is at the desired temperature, then
begin the forward (process) flow.
