Permanent Warming Systems

Reduces Start-up Time

• Pre-warms components, cutting fuel costs and unproductive time
  
• Maintains a warm or hot stand-by condition to minimize required “soak” periods that drain time and profits
  
• Reduces costly power purchases while helping you meet on-line commitments 

Controls Differential Expansion

• Reduces excessive blade seal wear
  
• Increases unit availability
  
• Prevent mechanical binding and damage
  
• Enhances structural integrity

Decreases Thermal Stress Cracking

• Keeps components above Fracture Appearance Transition Temperatures
  
• Reduces low-cycle fatigue and brittle fractures

Minimizes Corrosion

• Maintains component temperatures above dew point
  
• Decreases the formation of condensation

Built-in Safety

• High/low/deviation temperature alarm
  
• Individual zone ground-fault protection
  
• Zone heater-failure indicators
  
• Zone power-on indicators
  
• Zone control selectors
  
• Open thermocouple alarm    
  
• Power failure alarm
  
• Cabinet door interlock
• Custom alarms and interlocks

The typical Permanent Warming System has multiple separately controlled heating zones, each with unique thermal requirements. As shown, zones 1 through 4 can be accurately maintained within ±5° F of a given setpoint temperature. A setpoint temperature can be input manually or can be determined from the internal process fluid, such as steam

Team offers both manual and automatic control systems. Both types of systems provide user-friendly operation and safety protection. The typical Permanent Warming System Control network includes:

Single-loop Control

Typically local operation with control and power distribution components in one free standing unit.  Ideal for simple, manual control of up to 16 heating zones.

PLC Control Center

Local or remote option with user-friendly operator interface.  The PLC provides advanced and comprehensive capabilities for more sophisticated control.  Its ease of use and flexibility make this a very practical option.

Distributed Control System (DCS)

Team's engineers can design a system to network with your existing plant DCS.

Optional PC Supervisory Station

Trending analysis, data acquisition, and additional programming capabilities are possible for a more thorough thermal analysis and performance evaluation.
