HVAC Equipment
Reliable Ignition And Temperature Control for Modern HVAC Performance
Heating, ventilation, and air conditioning systems play a critical role in building safety, comfort, and operational uptime. Whether serving residential towers, commercial buildings, industrial facilities, or specialty climate systems, HVAC equipment must perform dependably through wide temperature swings, variable fuel quality, and years of continuous cycling.
KiddeFenwal solutions deliver the ignition reliability, temperature stability, and protective safety limits manufacturers depend on. Built for durability and engineered for precise performance, our Fenwal Controls branded line ensures that HVAC equipment operates safely, efficiently, and consistently, even in demanding environments.
HVAC System Fire & Safety Challenges
Modern HVAC designs face increasing performance expectations and regulatory pressures. These systems must reliably:
- Ignite burners safely across cold starts, rapid cycling, and variable gas conditions
- Prevent over-temperature events caused by blocked airflow, component wear, or unexpected heat buildup
- Maintain accurate temperature control for heating efficiency and occupant comfort
- Integrate with building automation systems for optimized performance
- Withstand vibration, moisture, power variations, and long-duty cycles
From furnaces and rooftop units to hydronic equipment and makeup-air systems, proper ignition and temperature control aren’t optional — they’re essential to equipment safety, longevity, and energy efficiency.
