Integrating this HVAC voltage monitor into your existing control circuit ensures that the 3-phase compressor protection is active the moment a fault is detected

this differential air pressure switch is the industry standard for verifying fan proof of flow and preventing unsafe operating conditions in commercial boilers and air handlers

This single-phase HVAC motor includes a 10 MFD 370 VAC start capacitor

As a direct replacement Fenwal ignition module

reliability is everything

Fenwal 12-E27121-000-05 Sensor Freon Integrating this HVAC voltage monitorAs an HVACR contractor, you know that reliable fire protection in commercial ducting and air handling equipment starts with the Fenwal 12 E27121 000 05. This Detect A Fire vertical mount heat detector is engineered with a rate compensation design, allowing it to accurately sense surrounding air temperature regardless of fire growth rate. Unlike standard rate of rise devices, the Fenwal heat sensor ignores transient thermal gradients to virtually
