Air Coils

Quality - Integrity - Reliability

Air Coils

PMT supplies replacement air coils for HVAC applications.  These coils can be designed based on your existing design documentation, or PMT can dispatch our design team to your site to reverse engineer your existing coils.

For applications where water chemistry is problematic, PMT can perform  an engineering evaluation to compare a new coil to your existing one, and then propose new coils made from alternate materials.

PMT can perform full thermal performance testing on the coils to validate heat transfer and confirm the design meets your specifications.  Installation services are also available.

Containment Fan Coils

PMT manufactured 30 containment fan coils for the Point Beach Plant. The original coils were in leaking due to age. The utility replaced all installed coils. These coils have a removable water box cover for cleaning. The original coils did not have water boxes. Call PMT today for specific information regarding coil services.
