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.
