Water/Water coolers offer a reliable cooling also in cases, in which on site water is contaminated or showing a high grade of hardness.
Contrary to water/air back cooling systems the water/water cooler can also be used effectively at installation sites with an ambient temperature of > 45°C.
 |
The water/water cooler has a secondary water circulation for cooling the probe. The water circulation is closed and is operated with purified water, so that the probe is protected against calcination and contamination.
The water of the secondary water circulation is backcooled in the tubular cooler by means of primary cooling water. Primary cooling water is onsite water having no set special requirements regarding contamination or hardening, because the primary connections of the tubular cooler are amply laid out accordingly.
The large connections enable the cooler to maintained, and in particular cleaned. |
 |
For the normal control of correct operation both primary and secondary circulation has pressure and temperature displays.
The cooler frame can be mounted next to the control and supply cabinet (see illustration), as well as on the rear panel of the cabinets. |
Optional equipment:
• Dual cooling for increased cooling capacity,
• by-pass emergency cooling system on mains power failure or voltage asymmetry
• Water leakage control system via a pressure switch, in case of a leakage and therefore a flux of water from the probe cooling circulation an alarm is automatically set off
• Other types on request
Remote controllable probe vertical devices of the DV-X series
SOBOTTA GMBH has been developing and engineering automatic transfer devices for high temperature applications for over 30 years. Additional equipment has been developed in cooperation with their users and adapted to special observation stages. This includes different designs of automatic rotating devices.

Pneumatic Rotating Device DV-P with quick-lock clamping ring
• Extremely flexible and versatile for use in furnace probes with radial view direction, optional viewing angle
• Rooms can be observed in full 360° view with just one furnace probe
• Where up to four furnace probes are required in conventional techniques, operation using the rotating device with only one TV positioned can take place. This results in significant cost savings, lower investment costs, lower repairs and maintenance expenses, fewer insulation losses
• Drive – option of pneumatic or electrical
|
• Rotation speed adjustable, also with option of remote parameter setting of speed during rotation
• Installation position optional
• Compact Design
• Integrated position detector for fixed positions or continuously variable analogue output as an option
• Smooth-running construction with integrated sealing flange, no additional friction forces
• Drive with high torque for the continuously industrial grade reliability
• No additional sealing technology necessary for the furnace, because Sobotta standard shutter boxes can be used
• Easy mounting on SOBOTTA KV-L- transfer devices, trouble-free retrofitting possible
• Rotation devices are available in operating angles between 90° and 360°
 |
Electrical rotation device with position detector
DV-E
• The optional position detector with analogue output allows the camera positions to be clearly defined in order to precisely localise defective cladding, faulty processes or early blockages
• A brake guarantees exact positioning without any stop delay. All control commands can be remote-controlled from the control centre
|
Electrical rotation device in heavy construction
DV-S
• The strengthened storage of the electrical rotating device in heavy construction guarantees continuously reliable handling of heavy weight probes. The heavy construction is recommended for furnace probes from a length of 1300 mm |
