The TRV5-60 temperature transmitter is designed for the connection of a TRG 5-6x temperature sensor (platinum resistance thermometer Pt100 to EN 60751), to enable the redundant acquisition and monitoring of its measured values. The measured temperature and any system malfunctions that occur are displayed directly on the TRV5-60 temperature transmitter, and made available via the CAN bus as a con- verted data telegram.

The temperature transmitter can be used as:

  • A safety temperature limiter/monitor in combination with a TRG 5-6x temperature sensor and URS 60/URS 61 safety control units.

Safety temperature limiters or monitors switch off the heating when the maximum admissible temperature is reached. Method of operation TYPE 2.BKP (+JV, with external lock) to EN 60730-1.

Visualisation and operation take place via the URB 60 or SPECTORcontrol operating unit.

Combinations of these units can be used as monitors or limiters in steam boiler and hot-water plants.

In combination with the URS 60 / URS 61 safety control unit, the TRV5-60 temperature transmitter is suitable for safety functions up to SIL 3.

It is an element of a safety circuit up to SIL 3 as per IEC 61508 in the SPECTORconnect system, and can transmit alarm notifications.

The TRV5-60 temperature transmitter has a dedicated TRG 5-6x temperature sensor, the readings of which are recorded and monitored redundantly.

The actual temperature is displayed on the temperature transmitter itself, as are any system malfunctions that occur.

The temperature in the transmitter terminal box is continually monitored by a temperature sensor on the PCB.

Behaviour in the event of alarms (limit values)

The alarm state is displayed on the TRV5-60 and transferred to the URS 6x safety control unit via CAN bus. After the delay time, the safety control unit switches off the connected safety circuit. The safety control unit does not lock independently during this process.

The following error messages:

  • Sensor malfunction
  • Communication failure

provoke an undelayed break in the safety circuit.

Automatic self-test

An automatic self-test periodically monitors the safety and function of the temperature sensor and measured value acquisition.

The data are transferred to the URS 60/URS 61 safety con- trol unit in the form of a black channel data telegram via the CANopen protocol using a CAN bus to ISO 11898, and saved there.

GESTRA Pump Trap UNA 25-PK, PN 40, DN 40 Condensate Lifter UNA 25-PS, PN 40, DN 40

GESTRA: The Ultimate Solution for Industrial Steam & Fluid Control Systems

PN 40 DN 40 – High Performance Steam Condensate Pump Trap

Reliable Condensate Removal Solution for Low-Pressure & Vacuum Steam Systems

The GESTRA Pump Trap UNA 25-PK and GESTRA Condensate Lifter UNA 25-PS are high-performance mechanical pump trap systems designed for efficient condensate removal when gravity drainage is not possible. Operating at PN 40 and available in DN 40, these units ensure safe, automatic, and energy-efficient condensate discharge in demanding industrial steam applications.

If you are searching for a steam pump trap, condensate lifter, or GESTRA UNA 25 pump trap, this solution offers maximum reliability, zero electricity requirement, and proven GESTRA engineering.

A pump trap combines the function of a steam trap and a condensate pump in a single unit. The GESTRA UNA 25-PK pump trap uses steam, compressed air, or gas as the motive medium to pump condensate from low-pressure or vacuum systems to a higher return line.

The UNA 25-PS condensate lifter is designed specifically to lift condensate when the condensate outlet is below the return line, ensuring continuous drainage without flooding equipment.

Available Models

  • GESTRA UNA 25-PK Pump Trap PN 40 DN 40

  • GESTRA UNA 25-PS Condensate Lifter PN 40 DN 40

2. Prevents Equipment Flooding

Ensures effective condensate removal from heat exchangers, coils, and process equipment operating under vacuum or low pressure.

3. Automatic & Reliable Operation

Fully mechanical design provides automatic cycling with minimal maintenance.

4. High Pressure Capability (PN 40)

Designed for industrial-grade performance with long service life.

  • Lifts condensate to higher return lines

  • Ensures continuous drainage without backpressure issues

  • Prevents water hammer and corrosion

  • Ideal for retrofit and new installations

The GESTRA UNA 25-PK and UNA 25-PS are widely used in:
