MVH Series
Medium Voltage Heater Controller
The MVH Series Medium Voltage Heater can be used in different heating applications across multiple industries including gas heaters, boilers, and steam heaters. Medium voltage heaters offer multiple benefits over low voltage heaters: lower installation cost, improved efficiency, energy savings, and lower maintenance cost.
| Applications | Gas heaters, boilers, steam heaters |
| Key Benefits | Lower cost, improved efficiency, energy savings |
| vs Low Voltage | Lower installation & maintenance cost |
Lower Installation Cost
MV heaters require less current for the same heating power — smaller cables, lower installation cost.
Improved Efficiency
Higher voltage operation delivers improved system efficiency over equivalent LV heaters.
Energy Savings
Reduced losses in wiring and switchgear compared to low voltage equivalents.
Lower Maintenance
Simplified distribution system means fewer components and lower long-term maintenance cost.
