COMPACT HEAT EXCHANGER – KL-TZ seriesPressure independent heat exchanger station

Heat transfer stations are designed for systems with a primary heating medium temperature up to 100°C and pressures up to 0.6MPa, it is installed the direct pressure connection to the piping system of the supplied object.



FUNCTIONAL DESCRIPTION

The primary heating water enters through a valve and strainer to transfer station, where it is divided into hot water for heating and exchanger - TV. Before exchanger TV classified mixing circuit, which serves to reduce the temperature of water entering the heat exchanger. Heating water for plate heat exchanger - UT is regulated by two-way control valve-rim and through the back flap is mixed to the heating curve with the return water secondary circuit UT. Heating water circulation system ensures circulation pump with electronically the controlled speed drives.

TV is prepared by direct heating and circulating cold water in the plate heat exchanger. TV temperature is controlled by a control valve with spring-return function at a constant temperature. Circulation from TV enters the headend through the isolating valve, strainer, circulation pump and check valve. Cold water enters the headend through, valves, strainer, check-valve and water meter. Before entering the heated medium to the heat exchanger is fitted with a fuse-ing valve. In exchanger TV cold water (mixed circular and cold water) is heated to the desired temperature (55°C) and via the isolating valve performs in of the supplied object. To balance of the hot water temperature setting and optimum performance values of the control valve it is recommended mount stainless steel buffer tank.


SPECIFICATIONS

  • Max. fluid temperature: 100°C
  • Max. medium pressure
  • Primary: 0.6 MPa
  • Max. power: 2000kW

 

STANDARD EQUIPMENT STATION

  • Plate heat exchanger: SWEP, Alfa Laval
  • Control valves: LDM, Siemens
  • Taps: BROEN
  • Pumps: Grundfos, Wilo

DESIGN support construction consists of a steel frame welded from thin sections, presented in which it is firmly held their own machinery. Primary distribution pipe and pipe sections UT is steel class. 11, duct section TV is steel class 17th The station is designed and constructional solution, the minimized noise and vibration operation.


Station Control Stations can be mounted control technology to the extent of the customer's choice. Simple controllers provide fully autonomous operation of the stations, including the choice of several time programs, setting equitherm dependencies with limited communication with the dispatching center. Programmable controllers offer a wide range of compact control at substations. Well-chosen programs can be up to optimize operation of the stations. Programmable controllers allow two-way communication with the control center, traffic monitoring, reporting, emergency situations, etc.

DIAGRAM diagram and used components can be replaced by the customer. Stations are supplied without pipe insulation that can be reordered, possibly in the plating compact. For the less accessible places it is possible to produce an atypical involvement and adapt best compact a defined space. Overall design of substations, including drawings, it is always consulted with the chief engineer and the client.
