Dragon’s Breath – Heat Blaster

The system uses compressed air and an industrial heat tube to produce the heat blast. The Dragon’s Breath – heat blaster hot air cannon stays hot with a constant low level of air flowing through it, until the Dragons Breath system is activated, and compressed air is blasted through the nozzle, thus blasting heat at the guests almost instantly. When the Dragon’s Breath is de-activated, the system almost instantly cuts off the heat the guests feel. The Dragon’s Breath system then goes into “ready” mode awaiting the next “go” signal.

Heater Control System

Heat Control System:

The Heat Controller utilizes a self-contained microprocessor based Process Controller. The unit monitors temperature utilizing a Type K thermocouple sensor and controls temperature with a rapid response three mode (PID) control scheme, with anti-reset windup. Numerous status and alarm functions are incorporated to monitor various system parameters.

The unit is housed in a NEMA 12 enclosure and contains the temperature controller and the necessary terminal blocks, transformers, safety relay and solid state relay to make up a complete system.

An independent high limit circuit is also provided. The sensor is a second Type K thermocouple. This circuit shuts off the internal safety relay should an over-temperature condition occur. It is totally independent of the microprocessor.

The following are some of the features:

  • USES TYPE K THERMOCOUPLE FOR PROCESS CONTROL
  • USES SECOND TYPE K THERMOCOUPLE FOR HIGH LIMIT
  • AUTOMATIC THERMOCOUPLE COLD JUNCTION COMPENSATION
  • HI LIMIT CIRCUITRY INDEPENDENT OF MICROPROCESSOR
  • ADVANCED RAPID RESPONSE 3 MODE CONTROL
  • BUILT IN SAFETY RELAY
  • BUILT IN SOLID STATE RELAY
  • BUILT IN CLASS 2 TRANSFORMER
  • EXTERNAL HEAT SINK
  • ON/OFF SWITCH
  • HEATER SNAP SWITCH INPUT
  • FLOW SWITCH INPUT
  • ACCESS CODE PARAMETER PROTECTION
  • EEPROM PARAMETER MEMORY
  • AUDIO ALARM/ANNUNCIATOR
  • ALL PARAMETERS SET IN SOFTWARE
  • NEMA 12 ENCLOSURE
  • TWO FOUR DIGIT LED DISPLAY
