Series MX40

The Series MX40 Discharge Air Temperature Control System is for use with atmos­pheric indirect fired heaters using a two-stage inducer. The controller senses and maintains a constant discharge air temper­ature by modulating the gas flow and staging the inducer. The Series MX40 controller is used with the E42, E52, and E62 Series modulators. Typical appli­ca­tions achieve a turndown of approx­i­mately 5:1 during continuous operation. 

 

System Components

  • A40 Series Amplifier
  • E42, E52, E62 Series Modulating Gas Valves
  • TD114+ Remote Temperature Selector (optional)
  • TS194Q/MT1 Discharge Air Temperature Sensor/Mixing Tube

Series MX4010

The Series MX4010 Discharge Air Temperature Control System is for use with split manifold atmos­pheric indirect fired heaters. The split manifold operates as two independent manifold sections sharing a single inducer. The controller senses and maintains a constant discharge air temper­ature by modulating one section of the manifold and staging the non-modulated section. The Series MX4010 controller is used with the E42, E52, and E62 Series modulators. Typical appli­ca­tions achieve a turndown of approx­i­mately 10:1 during continuous operation. 

 

System Components:

  • A40-SM2 Series Amplifier
  • E42, E52, E62 Series Modulating Gas Valves
  • TD114+ Remote Temperature Selector (optional)
  • TS194Q/MT1 Discharge Air Temperature Sensor/Mixing Tube

Signal Conditioners

The SC40 Series signal condi­tioner, used with the E42H, E52H, and E62H Series modulating gas valves, is designed to modulate atmos­pheric indirect fired heaters with a 2‑speed inducer. Most appli­ca­tions are able to achieve approx­i­mately a 5:1 turndown. The system is easily integrated into existing heater designs. The system’s relia­bility and simplicity greatly reduce the engineering time required to bring a high turndown modulating heater to market.

The SC40-SM2 Series signal condi­tioner is used with the E42, E52, E62 Series modulating gas valve. The sectioned — or split — manifold design operators as two independent manifolds sharing a single 2‑speed inducer. One manifold section is fully modulating, and the other section operates as a 2‑stage. Typical appli­ca­tions achieve a turndown of approx­i­mately 10:1.
