or differential air pressure in HVAC systems and industrial process control

the assembly features a high-intensity green LED indicator that resists the high-vibration and thermal stress common in overhead heating applications

this relay features Class B insulation and is rated for operational temperatures from -40°F to 149°F

reliability is everything

Can the BASO H17AA-2 be used in high-pressure systems

Fenwal 12-E27121-000-05 Sensor Freon or differential air pressure inAs 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
