An SCR controlled heater is a time proportioned heater that modulates to supply the exact amount of heat required to satisfy the zone requirements. Titus offers (2) types of SCR style electric reheat options and this article will help clarify the differences between the two. Our two SCR heater codes are the CXX and LXX codes. The CXX code is an SCR heating code that offers lower kW’s available per voltage than the LXX as well as other voltage requirements like 580V & 600V. The LXX code (Lynergy) is the Titus branded SCR heater which has more capabilities than the CXX code but no special voltages available.
CXX:
- Utilizes an air flow sensor instead of a standard mechanical air flow switch
- 0-10v DC or AC/DC pulse
- Special voltages and lower kw options are available
- No quick ship options available
LXX (Lynergy):
- More cost effective
- Faster lead time
- Utilizes a mechanical air flow switch instead of an air flow sensor
- 0-10VDC
- 2-10VDC
- 3 point floating
- Incremental
- On/off
- 2 stage
- 3 stage
- Binary
If you are looking for very low kW or voltages higher than 480V then the CXX code will work best. For faster lead times, competitive pricing, and more control functionality then the LXX Lynergy code will be the best choice.
