TriStar Hot Water Sets are engineered to match each application. Water temperature, water flow rate, steam supply characteristics, and condensate recovery are all considered when designing each system.

Flow rates range from 25 GPM to 400 GPM. Shell and Tube Design or Brazed Plate Designs in both carbon steel and 316 stainless steel models are available.

Electro-Pneumatic Control Loop

A complete control system for applications where sudden or large load changes, or rapid temperature changes occur. The system senses the current temperature of the process using an RTD. It then compares the current temperature to the set point using an electronic controller. The controller sends a corrective 4-20 ma electric signal to the positioner. The signal then controls pneumatic air supply to the steam control valve which increases or decreases the steam flow into the system. The change in steam flow raises or lowers the water (service fluid) temperature. Components include:

  • Steam Control Valve
  • Thermowell
  • Temperature Sensor (RTD)
  • RTD Extension Wire
  • Electronic Controller
  • Enclosure for Electronic Enclosure

Self-Operating Control Loop

Simple, and economical, control loop utilizing hydraulic line for controlling relatively stable systems, where small valve stroke modulations will correct temperature drift. The temperature sensing bulb sends a hydraulic control signal to the special steam valve. Components include the Self-Operating Temperature Regulator and the Thermowell for the temperature sensor.

Control Options

Depending on the steam supply pressure and quality, a steam control valve is selected to provide the correct amount of steam to meet the water heating demand.

Three different type of controls are available for the steam control valve:

Steam Control Valve Only

For plants and applications where the hot water set is going to be operated by the plant's Distributed Control System (DCS). Also for applications where the temperature sensor (RTD) is located far from the hot water set. A pneumatically operated steam control valve is supplied.  Two signal types are available:

  • 4-20 ma - Standard configuration
  • 3-15 psi air - For air-only operation

Engineered to Match Each Application

Hot Water Sets have many different names depending on their use and manufacturer. In the end, they all do the same thing: indirectly heat water using steam energy by means of a steam to water heat exchanger.

  • CIP
  • Pasteurization
  • Plate Heat Exchangers
  • Cooking Vessels
  • Process Heating
  • Reactor Vessels
  • Hose Stations
  • Washdown Stations
