Plate Heat Exchangers
Plate Heat Exchangers
Preface
With GEA Ecoflex you use the technical know how of one of the worldwide
leading manufacturers of plate heat exchangers (PHE).
We would like to make the handling of the plate heat exchanger as safe and
simple as possible. For this reason, these comprehensive operating instructions serve as your personal adviser who explains everything understandably and clearly: structure, function, installation, operation, maintenance,
troubleshooting, transport and repair.
We especially devote ourselves to the subject of safety, so that all possible
dangers or damage can be avoided from the start. For that reason alone, all
employees who deal with the plate heat exchanger should be able to refer to
these important operating instructions at all times.
In the concise table of contents you will quickly find what you are looking
for. If not, look in the index with page references. In the same way all technical terms are informatively explained. After all, no questions should
remain open, and in the case they do, your GEA Ecoflex agent or the central
service department is glad to assist you further.
Additional operating instructions for special applications supplement these
general operating instructions.
With this in mind, we wish you a trouble-free operation with GEA Ecoflex
plate heat exchangers.

Installation/Operating Manual
Installation/Operating Manual
The marking on the pump refers to the pump only.
Example of such marking: II 2 G c TX
Refer to the Temperature limits table for the temperatures permitted for the
individual pump variants. (⇨ )
An EC manufacturer's declaration is required for the shaft coupling; the shaft
coupling must be marked accordingly.
The motor has its own marking. The marking is maintained on the condition that the
temperatures the pump causes to develop at the motor flange and motor shaft are
permitted by the motor manufacturer.
The motors fitted by KSB on pumps with ATEX certification meet this condition.
2.10.2 Temperature limits
In normal pump operation, the highest temperatures are to be expected on the
surface of the pump casing and at the shaft seal.
The surface temperature at the pump casing corresponds to the temperature of the
fluid handled. If the pump is heated, the operator of the system is responsible for
observing the specified temperature classes and fluid temperature (operating
temperature).
The table below lists the temperature classes and the resulting theoretical
temperature limits of the fluid handled. (A possible temperature rise in the shaft seal
area has already been taken into account).
The temperature class specifies the maximum permissible temperature at the surface
of the pump set during operation. For the permissible operating temperature of the
pump in question refer to the data sheet.
Table 4: Temperature limits
Temperature class as per EN 13463-1 Max. permissible fluid
temperature
T1 Temperature limit of the pump
T2 280 °C
T3 185 °C
T4 120 °C
T5 85 °C
T6 Only after consultation
with the manufacturer
If the pump is to be operated at a higher temperature, the data sheet is missing or if
the pump is part of a pool of pumps, contact KSB for the maximum permissible
operating temperature.
If a pump is supplied without motor (as part of a pool of pumps), the motor specified
in the pump data sheet must meet the following conditions:
▪ The permissible temperature limits at the motor flange and motor shaft must be
higher than the temperatures generated by the pump.
▪ Contact the manufacturer for the actual pump temperatures.

The WITT hermetic refrigerant pump type is designed to
deliver exclusively refrigerant liquid at its boiling point.The pump is labelled with model and design limitation for
pressure and temperature.
The HRP refrigerant pump is designed with safety features, which ensures security from the escape of ammonia; in the event the stator can leaking the pump body and
the complete motor housing is designed to 25 bar pressure to contain high pressure refrigerantRefrigerant will
not escape from the pump or through the cable connections

Evaporative Condensers Baltimore Aircoil Company equipment needs to be properly installed, operated and maintained. Documentation of the equipment used, including a drawing, technical data sheet and this manual should be kept on record. To achieve long, trouble-free and safe operation, it is necessary to establish an operating plan including a programme of regular inspection, monitoring and maintenance. All inspections, maintenance and monitoring actions should be recorded in a cooling system logbook. The operating and maintenance instructions published here can be used as a guide to achieve these goals. In addition to establishing the operating plan and the cooling system logbook it is recommended to conduct a cooling system risk analysis, preferably by an independent third party. For the cooling system, scale, corrosion and biological control must be established and initiated when the system is first filled with water and administered on a regular basis thereafter in accordance with recognized Codes of Practice, (such as EUROVENT 9 - 5/6, ACOP HSC L8, Guide des bonnes pratiques, Legionella et tours aéroréfrigérantes, etc.). Water sampling, test results and corrective actions should be recorded in the cooling system logbook. For more specific recommendations on keeping your cooling system efficient and safe, contact your local BAC Balticare representative.

Baltimore Aircoil Company VX equipment has
been designed to give long, trouble-free
service when properly installed, operated, and
maintained. To obtain optimum performance and
maximum service life, it is important that a program
of regular inspection and maintenance be developed
and carried out. This bulletin is published as a guide
to establishing such a program.
Included in the bulletin are the recommended
services for start-up, operation and shutdown
and the approximate frequency for each. Note that
the recommendations on frequency of service are
minimums and where operating conditions are
severe, the services should be performed more
often. For each required service, follow the
procedures outlined under the “Maintenance
Procedures” section of this bulletin.
The VXT, VXI, and VXC models are illustrated in a
cutaway form on pages 2 and 3 with the major points
of inspection and service identified. A copy of the
unit certified drawing should also be available for
reference. If you do not have a copy of this
drawing, or if you need additional information about
operation or maintenance not covered in this
bulletin, contact the local B.A.C. representative. The
name and phone number are on a label at the
connection end of the unit
