Chilled water coil replacement goes wrong when the replacement is specified for the original system rather than the current one. Entering air conditions, supply temperature, flow rate, and face velocity can all change over the life of a commercial building without being reflected in the as-built documentation.

HX Coils reviews every chilled water coil application before fabrication begins. We wrote the full guide on what to confirm before the replacement is ordered.

Steam coil freeze damage is preventable. The vacuum breaker is what prevents it. The distributing steam coil design is what protects outdoor air preheat applications. The correct pressure and material specification is what protects high-temperature hot water coils.

HX Coils wrote a complete guide covering steam coil selection, freeze protection, vacuum breaker specification, and high-temperature hot water coil design in one reference.

Reactive coil replacement costs more than planned replacement. The coil costs the same either way. Everything around it costs less when it is planned.

HX Coils works with facility managers and property management organizations on coil replacement programs across the Mid-Atlantic. Inventory, condition assessment, priority scheduling, and capital planning. We wrote the full guide on how to get ahead of coil failures before they become emergencies.

Campus and district energy coil applications involve pressure ratings, temperature conditions, and performance documentation requirements that standalone building HVAC coils are not designed for.

HX Coils manufactures custom coils for campus and district energy applications across the Mid-Atlantic. Every application reviewed before fabrication begins. Performance documentation for energy modeling available. We wrote the full guide.

The nameplate records what a coil was when it left the factory. It does not record what the system has become in the decades since.

Water chemistry changes. Operating temperatures change. Airflow changes. A direct replacement replicates the original specification. It does not account for any of that.

HX Coils manufactures custom replacement coils for commercial and industrial HVAC applications across the Mid-Atlantic. We wrote a practical guide on what to look for before the next replacement order is placed.

07/01/2026

Face and bypass coils are a specific HVAC coil configuration used when precise discharge air temperature control is required across a wide range of load conditions. Laboratories, healthcare facilities, humidity-controlled spaces, high minimum airflow applications.

The coil operates at full design conditions at all times. Discharge air temperature is controlled by mixing conditioned air with bypass air, not by varying fluid flow through the coil. More stable, more precise, and the right answer for applications where standard valve control falls short.

HX Coils manufactures custom face and bypass coils for commercial and industrial applications across the Mid-Atlantic. We wrote the full specification guide.
